The Administration will end the COVID-19 vaccine requirements for international air travelers at the end of the day on May 11, the same day that the COVID-19 public health emergency ends. This means starting May 12, noncitizen nonimmigrant air passengers will no longer need to show proof of being fully vaccinated with an accepted COVID-19 vaccine to board a flight to the United States. CDC’s Amended Order Implementing Presidential Proclamation on Safe Resumption of Global Travel During the COVID-19 Pandemic will no longer be in effect when the Presidential Proclamation Advancing the Safe Resumption of Global Travel During the COVID-19 Pandemic is revoked .

Fact Sheet: Biden Administration Releases Additional Detail for Implementing a Safer, More Stringent International Air Travel   System

As we continue to work to protect people from COVID-19, today, the Biden Administration is releasing additional detail around implementation of the new international air travel policy requiring foreign national travelers to the United States to be fully vaccinated. This updated policy puts in place an international travel system that is stringent, consistent across the globe, and guided by public health. Starting on November 8, non-citizen, non-immigrant air travelers to the United States will be required to be fully vaccinated and to provide proof of COVID-19 vaccination status prior to boarding an airplane to fly to the U.S., with only limited exceptions. The updated travel guidelines also include new protocols around testing. To further strengthen protections, unvaccinated travelers – whether U.S. Citizens, lawful permanent residents (LPRs), or the small number of excepted unvaccinated foreign nationals – will now need to test within one day of departure. Today, the Administration is releasing the following documents to implement these requirements: 1) a Presidential Proclamation to Advance the Safe Resumption of Global Travel During the COVID-19 Pandemic; 2) three Centers for Disease Control and  Prevention (CDC) Orders on vaccination, testing, and contact tracing; and 3) technical instructions to provide implementation details to the airlines and their passengers.  With science and public health as our guide, the United States has developed a new international air travel system that both enhances the safety of Americans here at home and enhances the safety of international air travel. The additional detail released today provides airlines and international air travelers with time to prepare for this new policy ahead of the November 8 implementation date. As previously announced, fully vaccinated foreign nationals will also be able to travel across the Northern and Southwest land borders for non-essential reasons, such as tourism, starting on November 8. Additional detail on amendments to restrictions with respect to land borders will be available in the coming days. Travelers can find full details about today’s air travel announcement on the CDC and Department of State websites.  A summary is below: Fully Vaccinated Status:

  • Starting on November 8, non-citizen, non-immigrant air travelers to the United States will be required to be fully vaccinated and to provide proof of vaccination status prior to boarding an airplane to fly to the U.S.

Proof of Vaccination:

  • For foreign nationals, proof of vaccination will be required – with very limited exceptions – to board the plane.
  • Match the name and date of birth to confirm the passenger is the same person reflected on the proof of vaccination;
  • Determine that the record was issued by an official source (e.g., public health agency, government agency) in the country where the vaccine was given;
  • Review the essential information for determining if the passenger meets CDC’s definition for fully vaccinated such as vaccine product, number of vaccine doses received, date(s) of administration, site (e.g., vaccination clinic, health care facility) of vaccination.
  • The Biden Administration will work closely with the airlines to ensure that these new requirements are implemented successfully.

Accepted Vaccines:

  • CDC has determined that for purposes of travel to the United States, vaccines accepted will include FDA approved or authorized and World Health Organization (WHO) emergency use listed (EUL) vaccines.
  • Individuals can be considered fully vaccinated ≥2 weeks after receipt of the last dose if they have received any single dose of an FDA approved/authorized or WHO EUL approved single-dose series (i.e., Janssen), or any combination of two doses of an FDA approved/authorized or WHO emergency use listed COVID-19 two-dose series (i.e. mixing and matching).
  • More details are available in the CDC Annex here .

Enhanced Testing:

  • Previously, all travelers were required to produce a negative viral test result within three days of travel to the United States.
  • Both nucleic acid amplification tests (NAATs), such as a PCR test, and antigen tests qualify.
  • As announced in September, the new system tightens those requirements, so that unvaccinated U.S. Citizens and LPRs will need to provide a negative test taken within one day of traveling.
  • That means that all fully vaccinated U.S. Citizens and LPRs traveling to the United States should be prepared to present documentation of their vaccination status alongside their negative test result.
  • For those Americans who can show they are fully vaccinated, the same requirement currently in place will apply – they have to produce a negative test result within three days of travel.
  • For anyone traveling to the United States who cannot demonstrate proof of full vaccination, they will have to produce documentation of a negative test within one day of departure.

Requirements for Children:

  • Children under 18 are excepted from the vaccination requirement for foreign national travelers, given both the ineligibility of some younger children for vaccination, as well as the global variability in access to vaccination for older children who are eligible to be vaccinated.
  • Children between the ages of 2 and 17 are required to take a pre-departure test.
  • If traveling with a fully vaccinated adult, an unvaccinated child can test three days prior to departure (consistent with the timeline for fully vaccinated adults). If an unvaccinated child is traveling alone or with unvaccinated adults, they will have to test within one day of departure.

Limited Exceptions from the Vaccination Requirement:

  • There are a very limited set of exceptions from the vaccination requirement for foreign nationals. These include exceptions for children under 18, certain COVID-19 vaccine clinical trial participants, those with medical contraindications to the vaccines, those who need to travel for emergency or humanitarian reasons (with a US government-issued letter affirming the urgent need to travel), those who are traveling on non-tourist visas from countries with low-vaccine availability (as determined by the CDC), and other very narrow categories.
  • Those who receive an exception will generally be required to attest they will comply with applicable public health requirements, including, with very limited exceptions, a requirement that they be vaccinated in the U.S. if they intend to stay here for more than 60 days.

Contact Tracing:

  • The CDC is also issuing a Contact Tracing Order that requires all airlines flying into the United States to keep on hand – and promptly turn over to the CDC, when needed – contact information that will allow public health officials to follow up with inbound air travelers who are potentially infected or have been exposed to someone who is infected.
  • This is a critical public health measure both to prevent the introduction, transmission, and spread of new variants of COVID-19 as well as to add a critical prevention tool to address other public health threats.

DHS to Require Non-U.S. Individual Travelers Entering the United States at Land Ports of Entry and Ferry Terminals to be Fully Vaccinated Against COVID-19

New Requirements at Land Ports of Entry and Ferry Terminals Will Protect Public Health While Facilitating Cross-Border Trade and Travel

WASHINGTON – Beginning on January 22, 2022, DHS will require non-U.S. individuals seeking to enter the United States via land ports of entry and ferry terminals at the U.S.-Mexico and U.S.-Canada borders to be fully vaccinated for COVID-19 and provide related proof of vaccination, as COVID-19 cases continue to rise nationwide. These new restrictions will apply to non-U.S. individuals who are traveling for both essential and non-essential reasons. They will not apply to U.S. citizens, Lawful Permanent Residents, or U.S. nationals.

“Starting on January 22, 2022, the Department of Homeland Security will require that non-U.S. individuals entering the United States via land ports of entry or ferry terminals along our Northern and Southern borders be fully vaccinated against COVID-19 and be prepared to show related proof of vaccination,” said Secretary Alejandro N. Mayorkas. “These updated travel requirements reflect the Biden-Harris Administration’s commitment to protecting public health while safely facilitating the cross-border trade and travel that is critical to our economy.”

These changes – which were first announced in October 2021 and made in consultation with the White House and several federal agencies, including the Centers for Disease Control and Prevention (CDC) – will align public health measures that govern land travel with those that govern incoming international air travel.

Non-U.S. individuals traveling to the United States via land ports of entry or ferry terminals, whether for essential or non-essential reasons, must:

  • verbally attest to their COVID-19 vaccination status;
  • provide proof of a CDC-approved COVID-19 vaccination, as outlined on the CDC website ;
  • present a valid  Western Hemisphere Travel Initiative  (WHTI)-compliant document, such as a valid passport, Trusted Traveler Program card, or Enhanced Tribal Card; and,
  • be prepared to present any other relevant documents requested by a U.S. Customs and Border Protection (CBP) officer during a border inspection.

COVID-19 testing is not required for entry via a land port of entry or ferry terminal.

Although these new vaccination requirements do not apply to U.S. citizens, Lawful Permanent Residents, or U.S. nationals, all travelers are reminded to bring a  WHTI -compliant document when re-entering the United States. Non-U.S. individuals attempting to enter the United States irregularly, through any illegal means or without proper documentation, will continue to be expelled pursuant to CDC’s Title 42 public health order.

To help reduce wait times, travelers can take advantage of  facial biometrics  and CBP One™ , which is a single portal for CBP mobile applications and services.

Considering travel during the pandemic? Take precautions to protect yourself from COVID-19.

A coronavirus disease 2019 (COVID-19) vaccine can prevent you from getting COVID-19 or from becoming seriously ill due to COVID-19 . But even if you're vaccinated, it's still a good idea to take precautions to protect yourself and others while traveling during the COVID-19 pandemic.

If you've had all recommended COVID-19 vaccine doses, including boosters, you're less likely to become seriously ill or spread COVID-19 . You can then travel more safely within the U.S. and internationally. But international travel can still increase your risk of getting new COVID-19 variants.

The Centers for Disease Control and Prevention (CDC) recommends that you should avoid travel until you've had all recommended COVID-19 vaccine and booster doses.

Before you travel

As you think about making travel plans, consider these questions:

  • Have you been vaccinated against COVID-19 ? If you haven't, get vaccinated. If the vaccine requires two doses, wait two weeks after getting your second vaccine dose to travel. If the vaccine requires one dose, wait two weeks after getting the vaccine to travel. It takes time for your body to build protection after any vaccination.
  • Have you had any booster doses? Having all recommended COVID-19 vaccine doses, including boosters, increases your protection from serious illness.
  • Are you at increased risk for severe illness? Anyone can get COVID-19 . But older adults and people of any age with certain medical conditions are at increased risk for severe illness from COVID-19 .
  • Do you live with someone who's at increased risk for severe illness? If you get infected while traveling, you can spread the COVID-19 virus to the people you live with when you return, even if you don't have symptoms.
  • Does your home or destination have requirements or restrictions for travelers? Even if you've had all recommended vaccine doses, you must follow local, state and federal testing and travel rules.

Check local requirements, restrictions and situations

Some state, local and territorial governments have requirements, such as requiring people to wear masks, get tested, be vaccinated or stay isolated for a period of time after arrival. Before you go, check for requirements at your destination and anywhere you might stop along the way.

Keep in mind these can change often and quickly depending on local conditions. It's also important to understand that the COVID-19 situation, such as the level of spread and presence of variants, varies in each country. Check back for updates as your trip gets closer.

Travel and testing

For vaccinated people.

If you have been fully vaccinated, the CDC states that you don't need to get tested before or after your trip within the U.S. or stay home (quarantine) after you return.

If you're planning to travel internationally outside the U.S., the CDC states you don't need to get tested before your trip unless it's required at your destination. Before arriving to the U.S., you need a negative test within the last day before your arrival or a record of recovery from COVID-19 in the last three months.

After you arrive in the U.S., the CDC recommends getting tested with a viral test 3 to 5 days after your trip. If you're traveling to the U.S. and you aren't a citizen, you need to be fully vaccinated and have proof of vaccination.

You don't need to quarantine when you arrive in the U.S. But check for any symptoms. Stay at home if you develop symptoms.

For unvaccinated people

Testing before and after travel can lower the risk of spreading the virus that causes COVID-19 . If you haven't been vaccinated, the CDC recommends getting a viral test within three days before your trip. Delay travel if you're waiting for test results. Keep a copy of your results with you when you travel.

Repeat the test 3 to 5 days after your trip. Stay home for five days after travel.

If at any point you test positive for the virus that causes COVID-19 , stay home. Stay at home and away from others if you develop symptoms. Follow public health recommendations.

Stay safe when you travel

In the U.S., you must wear a face mask on planes, buses, trains and other forms of public transportation. The mask must fit snugly and cover both your mouth and nose.

Follow these steps to protect yourself and others when you travel:

  • Get vaccinated.
  • Keep distance between yourself and others (within about 6 feet, or 2 meters) when you're in indoor public spaces if you're not fully vaccinated. This is especially important if you have a higher risk of serious illness.
  • Avoid contact with anyone who is sick or has symptoms.
  • Avoid crowds and indoor places that have poor air flow (ventilation).
  • Don't touch frequently touched surfaces, such as handrails, elevator buttons and kiosks. If you must touch these surfaces, use hand sanitizer or wash your hands afterward.
  • Wear a face mask in indoor public spaces. The CDC recommends wearing the most protective mask possible that you'll wear regularly and that fits. If you are in an area with a high number of new COVID-19 cases, wear a mask in indoor public places and outdoors in crowded areas or when you're in close contact with people who aren't vaccinated.
  • Avoid touching your eyes, nose and mouth.
  • Cover coughs and sneezes.
  • Wash your hands often with soap and water for at least 20 seconds.
  • If soap and water aren't available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub your hands together until they feel dry.
  • Don't eat or drink on public transportation. That way you can keep your mask on the whole time.

Because of the high air flow and air filter efficiency on airplanes, most viruses such as the COVID-19 virus don't spread easily on flights. Wearing masks on planes has likely helped lower the risk of getting the COVID-19 virus on flights too.

However, air travel involves spending time in security lines and airport terminals, which can bring you in close contact with other people. Getting vaccinated and wearing a mask when traveling can help protect you from COVID-19 while traveling.

The Transportation Security Administration (TSA) has increased cleaning and disinfecting of surfaces and equipment, including bins, at screening checkpoints. TSA has also made changes to the screening process:

  • Travelers must wear masks during screening. However, TSA employees may ask travelers to adjust masks for identification purposes.
  • Travelers should keep a distance of 6 feet apart from other travelers when possible.
  • Instead of handing boarding passes to TSA officers, travelers should place passes (paper or electronic) directly on the scanner and then hold them up for inspection.
  • Each traveler may have one container of hand sanitizer up to 12 ounces (about 350 milliliters) in a carry-on bag. These containers will need to be taken out for screening.
  • Personal items such as keys, wallets and phones should be placed in carry-on bags instead of bins. This reduces the handling of these items during screening.
  • Food items should be carried in a plastic bag and placed in a bin for screening. Separating food from carry-on bags lessens the likelihood that screeners will need to open bags for inspection.

Be sure to wash your hands with soap and water for at least 20 seconds directly before and after going through screening.

Public transportation

If you travel by bus or train and you aren't vaccinated, be aware that sitting or standing within 6 feet (2 meters) of others for a long period can put you at higher risk of getting or spreading COVID-19 . Follow the precautions described above for protecting yourself during travel.

Even if you fly, you may need transportation once you arrive at your destination. You can search car rental options and their cleaning policies on the internet. If you plan to stay at a hotel, check into shuttle service availability.

If you'll be using public transportation and you aren't vaccinated, continue physical distancing and wearing a mask after reaching your destination.

Hotels and other lodging

The hotel industry knows that travelers are concerned about COVID-19 and safety. Check any major hotel's website for information about how it's protecting guests and staff. Some best practices include:

  • Enhanced cleaning procedures
  • Physical distancing recommendations indoors for people who aren't vaccinated
  • Mask-wearing and regular hand-washing by staff
  • Mask-wearing indoors for guests in public places in areas that have high cases of COVID-19
  • Vaccine recommendations for staff
  • Isolation and testing guidelines for staff who've been exposed to COVID-19
  • Contactless payment
  • Set of rules in case a guest becomes ill, such as closing the room for cleaning and disinfecting
  • Indoor air quality measures, such as regular system and air filter maintenance, and suggestions to add air cleaners that can filter viruses and bacteria from the air

Vacation rentals, too, are enhancing their cleaning procedures. They're committed to following public health guidelines, such as using masks and gloves when cleaning, and building in a waiting period between guests.

Make a packing list

When it's time to pack for your trip, grab any medications you may need on your trip and these essential safe-travel supplies:

  • Alcohol-based hand sanitizer (at least 60% alcohol)
  • Disinfectant wipes (at least 70% alcohol)
  • Thermometer

Considerations for people at increased risk

Anyone can get very ill from the virus that causes COVID-19 . But older adults and people of any age with certain medical conditions are at increased risk for severe illness. This may include people with cancer, serious heart problems and a weakened immune system. Getting the recommended COVID-19 vaccine and booster doses can help lower your risk of being severely ill from COVID-19 .

Travel increases your chance of getting and spreading COVID-19 . If you're unvaccinated, staying home is the best way to protect yourself and others from COVID-19 . If you must travel and aren't vaccinated, talk with your health care provider and ask about any additional precautions you may need to take.

Remember safety first

Even the most detailed and organized plans may need to be set aside when someone gets ill. Stay home if you or any of your travel companions:

  • Have signs or symptoms, are sick or think you have COVID-19
  • Are waiting for results of a COVID-19 test
  • Have been diagnosed with COVID-19
  • Have had close contact with someone with COVID-19 in the past five days and you're not up to date with your COVID-19 vaccines

If you've had close contact with someone with COVID-19 , get tested after at least five days. Wait to travel until you have a negative test. Wear a mask if you travel up to 10 days after you've had close contact with someone with COVID-19 .

Domestic travel for unvaccinated travelers

International travel for unvaccinated travelers, final thoughts on traveling without a covid vaccine.

Between constantly changing entry requirements, mandated quarantines, testing rules and vaccine provisions, traveling during the COVID-19 pandemic isn’t easy. If you’re not vaccinated, it's even harder. Some countries flat-out don’t admit unvaccinated travelers, while others require a mandatory quarantine and extra tests.

If you plan on traveling and aren't vaccinated, here’s what you need to know.

As recently as Jan. 12, the Centers for Disease Control and Prevention continues to recommend delaying travel until you’re fully vaccinated.

Requirements are up to each city and state. For example, while Illinois doesn’t have statewide restrictions, its recommendations differ based on the daily COVID-19 case rates of the state the traveler is arriving from. Unvaccinated travelers arriving from states with higher case rates are encouraged to secure a negative COVID-19 test taken within 72 hours of travel to Illinois. At the city level, unvaccinated travelers going to Chicago are asked to get tested for COVID-19 before and after arrival and to quarantine upon arrival.

Meanwhile, all travelers 16 and older who enter California via Los Angeles International Airport, Van Nuys Airport or Los Angeles Union Station are required to fill out a City of Los Angeles Traveler Form, agreeing to follow CDC travel guidance — or face up to a $500 fine.

Other states may be more flexible and have no recommendations or requirements related to vaccination, quarantine, forms or testing for visitors.

Tips for traveling domestically without a vaccine

If the required time frame for getting a COVID-19 test ahead of travel is less than 24 hours, check if an urgent care center near you offers a rapid results option. In addition, check if a PCR and/or antigen test will be accepted. Generally, results from an antigen test can be provided faster. If you have insurance, the test may be covered.

Before heading to your intended destination, check the city and state requirements and recommendations, because they may differ (like Chicago and Illinois). Find out if your destination has any special requirements based on the state you’re arriving from.

Some businesses require proof of vaccination for entry. Be prepared to be turned away from restaurants, bars, stores and other establishments if this is the case.

Check if there are any ongoing testing requirements. For example, unvaccinated travelers staying in Puerto Rico longer than a week must submit weekly COVID-19 test results.

Traveling internationally may present a greater number of obstacles, especially due to different systems and a potential language barrier. Some countries don't allow unvaccinated travelers to enter, period . For example, travel to the majority of European countries is possible only to those who are vaccinated. If you’re not vaccinated, make sure the country you want to visit will allow you entry.

In addition, before returning to the U.S., you’re required to provide proof of a negative COVID-19 test taken within one day of the flight's departure. While abroad, you’ll need to go to a COVID-19 testing center. Unlike getting tested in the U.S., COVID-19 tests abroad aren't covered by insurance, so you'll need to budget for the out-of-pocket cost .

Furthermore, you should book your accommodations wisely. Does the hotel you want to stay at allow unvaccinated guests? Will you be able to dine at the hotel restaurant? Can you use the spa or gym facilities? These are important questions you’ll need to consider before booking an international hotel stay.

Scrutinize your access to activities and other places you’d like to visit during your trip, too, like restaurants and museums. On my recent trip to Germany, I had to show my proof of vaccination and identification in every bar, restaurant, shop and hotel I entered.

If you’re unvaccinated, you may be refused entry to all these places, which can ruin your trip.

Tips for traveling internationally without a vaccine

Get travel insurance with Cancel For Any Reason coverage since entry requirements are changing constantly. What happens if you book a nonrefundable flight and hotel, and a week before your departure, your destination stops allowing in unvaccinated travelers? If you have travel insurance with CFAR, you’ll be able to cancel your trip and get your nonrefundable deposits back so long as changes aren’t made at the last minute. For example, with CFAR coverage from Berkshire Hathaway Travel Protection, "you may only be eligible if you purchase CFAR at the time of your base policy purchase, insure your full trip cost, and cancel more than 48 hours prior to departure," according to the company's website.

Confirm entry eligibility for your must-have experiences, like restaurants, museums, shopping malls or bars and clubs. Double-check that your hotel will allow you entry as well.

Research COVID-19 testing sites in the area before departure. Will you need to travel far to get your test? Consider travel time when making a test appointment.

Check if there's an app that your destination country uses that will accept your pre-departure negative COVID-19 test result. This step could make it easier to visit any bars, hotels, shops, restaurants and museums you’d like to check out.

Traveling domestically and internationally may pose a new set of challenges for those who are unvaccinated. Be sure to keep up to date with the latest requirements to make sure that your trip goes smoothly. International travel may result in many more difficulties, so if you’re not prepared to deal with all the uncertainties of being abroad, consider travel to a location within the U.S.

What is COVID-19?

Who can get covid-19, can i travel if i recently had covid-19, what can travelers do to prevent covid-19, more information.

CDC Respiratory Virus Guidance has been updated. The content of this page will be updated soon.

Coronavirus disease 2019 (COVID-19) is a respiratory illness caused by the virus SARS-CoV-2. The virus spreads mainly from person to person through respiratory droplets and small particles produced when an infected person coughs, sneezes, or talks. The virus spreads easily in crowded or poorly ventilated indoor settings.

People with COVID-19 have reported a wide range of symptoms   – ranging from no or mild symptoms to severe illness. Symptoms may appear 2–14 days after exposure to the virus. Possible symptoms include fever, chills, cough, shortness of breath, fatigue, muscle aches, headache, new loss of taste and smell, sore throat, runny nose, nausea, vomiting, or diarrhea.

Anyone can get COVID-19. However, some people are more likely than others to get very sick if they get COVID-19. These include people who are older, are  immunocompromised , or have certain  disabilities , or have  underlying health conditions .  Vaccination, past infection, and timely access to testing and treatment can help protect you from getting very sick from COVID-19.

Yes, you can travel once you have ended isolation . Check CDC guidance for additional precautions, including testing and wearing a mask around others. If you recently had COVID-19 and are recommended to wear a mask, do not travel on public transportation such as airplanes, buses, and trains if you are unable to wear a mask whenever around others.

Get  up to date  with your COVID-19 vaccines before you travel and take steps to protect yourself and others . Consider wearing a mask in crowded or poorly ventilated indoor areas, including on public transportation and in transportation hubs. Take additional precautions if you were recently exposed to a person with COVID-19. Don’t travel while sick.

If you have a  weakened immune system  or  are at increased risk for severe disease talk to a healthcare professional before you decide to travel.  If you travel, take multiple prevention steps to provide additional layers of protection from COVID-19, even if you are up to date with your COVID-19 vaccines. These include improving ventilation and spending more time outdoors, avoiding sick people, getting tested for COVID-19 if you develop symptoms, staying home if you have or think you have COVID-19, and seeking treatment if you have COVID-19.

Consider getting travel insurance in case you need medical care abroad .

Consider getting a COVID-19 test if you:

  • Develop COVID-19 symptoms before, during, or after travel.
  • Will be traveling to visit someone who is at higher risk of getting very sick from COVID-19.
  • Were in a situation with a greater risk of exposure during travel (e.g., in an indoor, crowded space like an airport terminal while not wearing a mask).

If you traveled and feel sick, particularly if you have a fever, talk to a healthcare professional, and tell them about your recent travel.

The countries you can travel to without a vaccine

By Abigail Malbon

The 28 most popular countries you can travel to without a vaccine

Travel around the world is easier now, particularly for those who are fully vaccinated with an approved Covid vaccine – but some countries are allowing unvaccinated travellers to enter. Yet with restrictions constantly changing, how do the latest rules affect those who aren't fully vaccinated, and which countries are allowing tourists to enter if they're unvaccinated?

Where can I travel unvaccinated?

There are currently a number of countries that will allow visitors who have not been vaccinated to enter. A few of them are in Europe , and the others are slightly farther afield. We recommend always closely following UK health guidance, including having your Covid vaccine and booster if you are able to. Before travelling, you should regularly check government guidelines both for the country you might be considering visiting and for the UK when you return.

You can find the full list of countries allowing people to enter without a vaccine below:

Since 1 May 2022, unvaccinated travellers are able to visit the country without proof of a negative PCR or rapid antigen test. Passenger locator forms are also no longer required.

Arrivals may, however, be required to undergo a rapid Covid test on arrival. If you test positive on arrival in Greece, you (and those you are travelling with) will have to self-isolate for at least five days, either at home or in a hotel (this will be paid for by the Greek state). If you have no symptoms on day five you will be allowed to leave quarantine.

For holiday inspiration, see our guide to the best Greek Islands to visit .

Read the rules on travel to Greece .

2. Portugal and Madeira

Portugal ’s mainland and Madeira are open to travellers who have not been vaccinated, as long as they can prove they don't have coronavirus when they enter the country. To enter mainland Portugal, you will be required to show proof of a negative PCR test taken within 72 or an antigen test taken within 24 hours of departure for the country as well as complete and submit a traveller questionnaire before departure for the country. Self-administered tests are not accepted. Your temperature will also be screened on arrival.

To enter Madeira, you must register on the Madeira Safe travellers platform and download a QR code to present to airport staff on arrival. You must provide proof of a negative antigen test taken within 48 hours of departure that has been administered by a trained healthcare professional.

Your airline may deny boarding if you cannot show one of these documents when you check in for your flight. Check with your airline before you travel.

A blue mind

Unvaccinated adult travellers can enter Spain if they are able to show proof of a negative test taken before entering the country. Previously, only fully vaccinated travellers aged 12 and over could enter Spain from the UK, but the destination has relaxed rules slightly, so it is now accepting negative PCR tests taken in the 72 hours before departure for the country or negative antigen tests taken in the 24 hours before departure for the country in lieu of full vaccination in adults. However, those who cannot meet either criteria will not be able to enter.

As of 1 February, you need to have received your second jab between 14 and 270 days before travel to Spain and the Canary Islands to be classed as fully vaccinated. Children aged 12-17 no longer need to show proof of a vaccine, but will need a negative PCR test to enter.

Read the rules on travel to Spain .

Unvaccinated travellers can enter Croatia without showing proof of a vaccine or negative test. The requirement to fill out a passenger locator form also no longer exists.

Read the rules on travel to Croatia .

Unvaccinated travellers to  Cyprus  must provide proof of a negative PCR test taken within 72 hours before departure for the country or an antigen test taken in the 24 hours before departure for the country. Travellers over 12 may then be asked to take another PCR test upon arrival at Larnaca or Paphos airports, and remain in isolation until the result comes back (this should take roughly three hours). This costs €15–€19 and must be paid for by the traveller.

Read the rules on travel to Cyprus .

If you are unvaccinated and over 12 years old, you must provide a negative PCR test result taken within 72 hours or an antigen test result taken within 48 hours pre-departure for entry to France.

Read the rules on travel to France .

7. Maldives

All travellers to the Maldives must fill in a Traveller Declaration form in the 72 hours prior to departure. A PCR test is no longer required regardless of vaccination status.

Read the rules on travel to the Maldives .

Unvaccinated tourists entering Italy from the UK must show a negative PCR test taken within 48 hours before entering, or a negative lateral flow test taken within 48 hours before entering. The requirement to fill in a passenger locator form has now been lifted.

Read the rules on travel to Italy .

9. Dubai and United Arab Emirates

You do not have to be fully vaccinated to visit the UAE. Unvaccinated arrivals to the Emirates must present evidence of a negative PCR test taken 48 hours before departure. Unvaccinated travellers from the UK to Dubai may be required to have a Covid-19 PCR test on arrival.

Read the rules on travel to Dubai .

10. Slovenia

Unvaccinated British travellers to Slovenia must provide a Digital Passenger Locator Form, but are not required to show proof of a negative test or vaccination to enter.

You do not need to be fully vaccinated to visit Turkey, but you must be able to show proof of a negative PCR test (taken no more than 72 hours before entry), rapid antigen test (taken no more than 48 hours before entry), or proof of a recent recovery from Covid-19 within the last six months. Arrivals into the country should also show an online form completed 72 hours before travel and will be subject to a medical evaluation for symptoms of coronavirus, including temperature checks. Arrivals may be subject to random PCR testing on arrival.

18. Cape Verde

You do not need to be fully vaccinated to enter Cape Verde, but you do need to be able to prove that you don't have Covid, either with a negative PCR test taken 72 hours before departure for the country or a lateral flow test taken 48 hours, when you check-in for your flight to Cape Verde.

19. Iceland

On 25 February 2022 all Covid restrictions were removed, including domestic rules. This means you do not need to test or show proof of vaccination status to enter the country.

20. Luxembourg

Those who are not vaccinated need to show proof of a negative PCR test taken no more than 48 hours before their flight, or a negative lateral flow test taken no more than 24 hours before.

Foreign tourists are required to pay BZ$36 (US$18) for Belize Travel Health Insurance – this is mandatory even if you already have personal travel insurance and helps protect against incurred medical and non-medical expenses should you test positive for Covid during your stay in Belize.

There are no direct flights from the UK to Belize, so it's important to check the rules of the country you will be transiting through too.

The Ultimate Guide to Maintaining Long-Lasting Friendships While Traveling

With Florida being a popular tourist destination, many unvaccinated individuals may be wondering if they should travel to the state. While Florida has reopened its doors to tourists, there are potential risks for unvaccinated travelers visiting the state that need to be taken into consideration.

One of the biggest risks for unvaccinated travelers in Florida is the potential for COVID-19 exposure. The state has seen high transmission rates, and there is a risk of coming into contact with the virus, particularly in crowded tourist areas. Unvaccinated individuals are at a higher risk of contracting and spreading the virus, which could lead to serious health complications or transmission to vulnerable individuals.

Another risk for unvaccinated travelers in Florida is the limited access to healthcare resources. With high transmission rates and potential outbreaks, the healthcare system in the state may become overwhelmed. Unvaccinated individuals may face challenges in accessing timely medical care if they were to fall ill during their trip.

Additionally, there is the risk of facing certain restrictions and limitations as an unvaccinated traveler in Florida. Some businesses and attractions may require proof of vaccination or negative COVID-19 tests for entry. This could limit the experiences and activities available to unvaccinated individuals, potentially impacting their travel plans.

It is important for unvaccinated travelers to be aware of the potential risks and take necessary precautions if they decide to visit Florida. This includes practicing good hygiene, such as frequent handwashing and wearing face masks in crowded areas. It is also recommended to maintain social distancing whenever possible and avoid large gatherings.

Travelers should stay informed about current COVID-19 guidelines and regulations implemented by the state and local authorities in Florida. These guidelines may change frequently, so it is crucial to stay updated on any travel advisories or restrictions that may affect unvaccinated individuals.

Before traveling to Florida, unvaccinated individuals should consider consulting with a healthcare professional to assess their individual risk factors and discuss any necessary precautions for their specific situation.

Overall, while Florida may be open to tourists, unvaccinated travelers should carefully weigh the potential risks and make an informed decision based on their health status and personal circumstances. It is crucial to prioritize personal health and safety when considering travel plans during the ongoing COVID-19 pandemic.

Florida is a popular travel destination for many, but what if you are unvaccinated and unable to travel there? Don't worry, there are still plenty of alternatives for unvaccinated individuals who cannot make it to Florida. Here are some options to consider:

  • Outdoor Activities: If you enjoy the outdoors, there are numerous activities you can partake in closer to home. Explore local hiking trails, go camping, or visit nearby state parks. These activities allow you to enjoy nature and get some exercise while avoiding crowded indoor spaces.
  • Beaches or Lakes: If you're looking for a beach-like experience, consider visiting a nearby lake or river. Many regions have beautiful waterfront areas where you can relax, swim, or have a picnic. Just make sure to follow local guidelines and practice social distancing if the area is popular.
  • Cultural Experiences: Florida is known for its vibrant culture, but you can find cultural experiences in other locations as well. Visit local museums, art galleries, or historic sites in your area. These attractions offer opportunities to learn, appreciate art, and immerse yourself in the local culture.
  • Road Trips: Instead of flying to Florida, consider planning a road trip to nearby destinations. Explore neighboring states and discover hidden gems along the way. This allows you to have a change of scenery and enjoy the journey itself, even if you can't make it to Florida.
  • Staycation: If you're unable to travel at all, embrace the idea of a staycation. Turn your home into a vacation destination by creating a relaxing ambiance. Try new recipes, watch travel documentaries, and set aside time for self-care. Seek out local attractions like nearby parks, gardens, or even local spas to add some variety to your staycation.

Remember, it's essential to stay informed about current travel guidelines and restrictions in your area. Stay updated with local health department recommendations and make decisions that prioritize your safety and the safety of others.

While Florida may be off-limits for now, there are still plenty of enjoyable alternatives for unvaccinated individuals. So, explore your local area, try new activities, and make the most of your time, wherever you may be.

Measles outbreak mapped: Signs of the incredibly infectious disease and how it spreads

H ealth officials in the US are on alert due to a widespread measles outbreak with several clusters identified by the Centers for Disease Control and Prevention .

The CDC has already identified 58 new measles cases in 2024 — the same number on record for the whole of 2023. It said in a report released this week that 94% of the cases identified were linked to international travel and mostly affected children aged 12 months and older who had not received the measles-mumps-rubella (MMR) vaccine.

Measles is highly contagious, as one person infected with it can infect 9 out of 10 unvaccinated individuals with whom they come into close contact. Other countries including Austria, the Philippines, Romania, and the UK are also experiencing outbreaks.

Ten infections have been reported in Chicago, including eight people living at a shelter for migrants which houses around 1,900 people. The Chicago Department for Public Health said this was the first instance of measles detected locally since 2019. Two of the cases — an adult and a child — were not shelter residents.

An outbreak was also recorded in Philadelphia this year, with nine cases confirmed as of January 16. The health department listed several addresses where people might have been exposed, including multiple hospitals and a daycare.

Another warning was issued by health officials in Virginia in January regarding potential measles exposure at Dulles International Airport and Reagan Washington National Airport after a person who had contracted measles during international travel was present there. Officials urged anyone who believed they may have been exposed and was not vaccinated for measles to be vigilant for potential symptoms. The recommended period for monitoring symptoms extended until January 25, 2024.

A measles outbreak occurred in Idaho in September 2023, when a resident of Nampa, the state's third largest city, returned home from a trip abroad. Last year, parents in Idaho opted out of state-required vaccines for 12% of kids entering kindergarten, the highest rate in the nation.

As a viral illness, measles can be very dangerous and cause severe health complications including pneumonia, encephalitis, and death, especially in unvaccinated persons. The initial symptoms usually include fever, cough, runny nose, and conjunctivitis which last two to four days before a rash develops.

The incubation period for measles, from exposure to fever, is usually about 10 days, while rash onset is typically visible around 14 days after initial exposure. The CDC explains: "The virus is transmitted through direct contact with infectious droplets or by airborne spread when an infected person breathes, coughs, or sneezes, and can remain infectious in the air and on surfaces for up to 2 hours after an infected person leaves an area. Individuals infected with measles are contagious from 4 days before the rash starts through 4 days afterward."

Worries over the potentially lethal infection have led to warnings for parents to monitor any symptoms. Renuga Vivekanandan, MD, assistant dean and professor at Creighton University School of Medicine Nebraska, said earlier this year: "It is important to monitor measles cases and be vigilant.

Vivekanandan blamed a decrease in vaccinations for the increase in cases, adding: "Overall, there has been vaccination hesitancy since the pandemic, with a decrease in vaccinations among children who can develop complications from measles, in addition to significant bad outcomes, such as meningitis. Staying up to date on the MMR vaccine can boost immunity and help prevent outbreaks."

The CDC issues new rules for bringing dogs into the U.S., aimed at keeping out rabies

Rob Stein, photographed for NPR, 22 January 2020, in Washington DC.

Traveling internationally with a dog — or adopting one from abroad — just got a bit more complicated. The CDC issued new rules intended to reduce the risk of importing rabies. mauinow1/Getty Images/iStockphoto hide caption

Traveling internationally with a dog — or adopting one from abroad — just got a bit more complicated. The CDC issued new rules intended to reduce the risk of importing rabies.

The Centers for Disease Control and Prevention announced new rules Wednesday aimed at preventing dogs with rabies from coming into the United States.

Under the new regulations, all dogs entering the U.S. must appear healthy, must be at least six months old, must have received a microchip, and the owner must verify the animal either has a valid rabies vaccine or has not been in a country where rabies is endemic in the last six months.

Dogs coming from a country that is considered at high risk for rabies and who received a rabies vaccine from another country must meet additional criteria. Those include getting a blood test before they leave the other country to make sure the animal has immunity against rabies, a physical examination upon arrival and getting a U.S. rabies vaccine. If the dog doesn't have a blood test showing immunity, it must be quarantined for 28 days.

These are much stricter requirements than existing regulations for dog importation — for those who want to adopt from abroad and for those traveling internationally with their pets.

Vaccine hesitancy affects dog-owners, too, with many questioning the rabies shot

Shots - Health News

Vaccine hesitancy affects dog-owners, too, with many questioning the rabies shot.

But, U.S pet owners shouldn't panic, says Dr. Emily Pieracci , a CDC veterinary medicine officer. "This really isn't a big change," she says. "It sounds like a lot, but not when you break it down, it's really not a huge inconvenience for pet owners."

Rabies was eliminated in dogs in the United States in 2007 , but unvaccinated canines can still contract the disease from rabid wildlife such as raccoons, skunks or bats.

And rabies remains one of the deadliest diseases that can be transmitted from animals to humans around the world. Globally, about 59,000 people die from rabies each year. The illness is nearly always fatal once a person begins to experience symptoms .

Today, pet dogs in the United States are routinely vaccinated against rabies.

"This new regulation is really set to address the current challenges we're facing," Pieracci says. Those include an increased risk of disease "because of the large-scale international movement of dogs," she adds, as well as fraudulent documentation for imported dogs.

The U.S. imports an estimated 1 million dogs each year. In 2021, amid a surge of pandemic-inspired dog adoptions, the CDC suspended importations from 113 countries where rabies is still endemic because of an increase in fraudulent rabies vaccination certificates. The countries include Kenya, Uganda, Brazil, Colombia, Russia, Vietnam, North Korea, Nepal, China and Syria.

That suspension will end when the new rules go into effect Aug. 1.

"This will bring us up to speed with the rest of the international community which already has measures in place to prevent the importation of of rapid dogs," Pieracci said. "So, we're playing catch-up in a sense."

The new regulations replace rules that date back to 1956. Those rules only required that dogs be vaccinated before entering the country.

"As you can imagine a lot has changed since then," Pieracci says. "International travel has increased dramatically and people's relationships with dogs have changed since the 1950s. During that time, it really wasn't common for dogs to be considered family member. They didn't sleep in peoples' beds. They certainly didn't accompany them on international trips."

The new rules won praise from the American Veterinary Medical Association . The organization "is pleased to see the implementation of this new rule that will help protect public health and positively impact canine health and welfare," said Dr. Rena Carlson, president of the AVMA in a statement to NPR.

Dog rescue advocates also welcomed the changes.

"This updated regulation will allow us to continue bringing dogs to the U.S. safely and efficiently," Lori Kalef, director of programs for SPCA International, said in a statement.

"We have seen that dogs have been a lifeline for U.S. service members during their deployments. One of our key programs reunites these service members and their animal companions here in the U.S. once they have returned home," she said. "The CDC's commitment to improving its regulations has a profound impact on the animals and service members we support, and this new policy is an important piece of that effort."

I’m a U.S. Citizen. Where in the World Can I Go?

For Americans eager to resume international travel, here are the countries that currently allow U.S. citizens to enter, though there may be restrictions, including vaccine requirements.

This list is no longer being updated. Find the latest coronavirus updates here .

Most of the world’s countries are open to travelers from the United States, and many nations are easing their requirements for visitors to test or quarantine. Some countries that had fully closed to foreign tourists — including Israel, Morocco, Bhutan, Australia and New Zealand — have now reopened to U.S. visitors, although they may continue to impose testing, vaccination or quarantine requirements.

In Europe, a growing number of nations — including Germany, Greece, Italy, Ireland, Switzerland and the United Kingdom, among many others — have eliminated their Covid-related travel restrictions for the summer travel season. Meanwhile, several Southeast Asian nations that had closed their borders to tourists have now reopened. Laos, Thailand, Vietnam, Indonesia, Malaysia, Myanmar and Cambodia are once again welcoming American visitors, although vaccine or testing requirements are in force in most cases.

For its part, the United States has lifted the requirement that inbound passengers, including returning Americans, provide a negative test result taken within one day of departure. The decision to lift the test requirement will be re-evaluated in September; the rule could be reinstated if authorities deem it necessary.

The Centers for Disease Control and Prevention, meanwhile, continues advising Americans not to travel internationally until they are fully inoculated against Covid-19.

Those wanting to learn about the coronavirus risk in a specific country can visit the C.D.C. website where a four-tier ranking system provides guidance. The agency reserves the highest “Level 4” ranking for countries with “special circumstances” that include spiking case numbers, the emergence of worrying variants, or threats to the viability of health care infrastructure. (Levels 1 to 3 are still based primarily on Covid-19 case counts.) At the moment, no countries are classified at Level 4; those at Level 3, which have a “high” incidence of Covid-19, are indicated in the list below. For information on entry requirements like testing and quarantine, as well as curfews and movement restrictions, the State Department’s website offers detailed information by country.

What follows is a list of countries that are open to tourists from the United States.

Baylor College of Medicine Blog Network

On March 18, the Centers for Disease Control and Prevention issued a Health Advisory warning of an increase in both global and U.S. measles cases. There were 132 confirmed cases in the U.S. from January 1 to May 9, which emerged as a result of eight outbreaks compared to a mere 58 cases in total in 2023. As practicing pediatricians trained since the widespread use of vaccines, we have never seen measles and never expected to see it in our careers. Some of our colleagues have seen measles, and their stories reinforce the severity of the disease. The rapid rise in measles cases is worrisome as it is affecting children in growing numbers around the world. We need to stop it together.

What is measles ?

Measles is a virus that spreads very easily. Nine out of 10 unvaccinated children exposed to measles will get the disease. It causes high fever, cough, runny nose and eye redness followed by a rash. Children can also have life-threatening complications like pneumonia and swelling of the brain. Symptoms can take up to three weeks to appear after exposure.

How did measles come back?

In pre-vaccination years, there were 3 to 4 million cases of measles and 400 to 500 deaths from measles each year in the U.S. The measles, mumps and rubella vaccine (MMR) was introduced in 1963. By 2000, measles cases decreased by 90% and were virtually eliminated in the U.S. This means that cases seen in the U.S. after 2000 were more likely due to travel than being exposed to the virus in the U.S.

Vaccination rates have  dropped since the 1980s, partly because of vaccine misinformation. The COVID-19 pandemic also made it difficult for children to get vaccinated against other non-COVID viruses.

These low vaccination rates have resulted in the measles virus making a comeback in the U.S. The measles virus is still common around the world and it is increasing globally because of low vaccination rates. When children travel to the U.S. or unvaccinated children from the U.S. travel to other countries, the virus can spread.

What is causing the current outbreaks?

If a child with measles is in contact with a child too young to receive the MMR vaccine, there will usually be a small number of cases. Others may be vaccinated so the virus stops spreading. Outbreaks in the U.S. happen when one of these measles cases finds a group of unvaccinated children and keeps spreading.

This year, 20 states have reported measles cases, with recent outbreaks in Chicago , New York and Florida .

How do I protect my children?

Getting the vaccine is much, much safer than getting the measles virus . The comparison is not even close.

Make sure your child is vaccinated. The MMR vaccine is safe and highly effective. Children should have one dose at 1 year old and a second dose at 4 years old. If your baby will be traveling out of the country, talk to their pediatrician about vaccinating as young as six months old. Two doses of the vaccine protect 98% of children, so they are unlikely to get the virus if they are exposed.

If finding a vaccine is difficult for your family, there are options for free vaccines for children who qualify through the Vaccines for Children Program . You can find a clinic here: https://findahealthcenter.hrsa.gov/ (site in multiple languages).

What else can we do?

Making sure your family is vaccinated is critical, but there are other ways we can prevent measles from spreading in our communities. Make sure you are registered to vote and choose candidates who you believe prioritize your community’s health. We can encourage our local representatives to write and vote for policies that encourage high vaccination rates and require proof in daycares and schools. We can also encourage public health surveillance and participate in community surveys given by our local and national public health officials.

How to Check If You’re Immune to Measles

Certain adults may need to get an additional dose of the measles vaccine. Here’s how to know if you have adequate immunity to measles

By Tara Haelle

Measles virus

Now is a good time to check if you have been vaccinated or have immunity to measles.

James Cavallini/Science Source

The U.S. is in the midst of one of its largest measles outbreaks since the disease was declared eliminated from the country in 2000. Its elimination two decades ago meant that measles no longer circulates on its own in the U.S. But outbreaks can occur there when a traveler—such as an infected tourist returning from a country where measles has been spreading—introduces the virus.

As of May 2 the Centers for Disease Control and Prevention reported that so far this year there have been 131 cases in 21 states , stretching from California and Washington State to New York State and New Jersey. Measles is possibly the most contagious disease that can infect humans: it’s airborne and remains in the air several hours after an infected person leaves an area, and it stays on surfaces for up to two hours. Just one person with measles can infect nine out of 10 nonimmune individuals who encounter that person’s aerosols. And it’s estimated that in an unvaccinated population, one person with measles would infect about 12 to 18 people on average. Epidemiologists estimate that at least 95 percent of a population needs to be vaccinated to prevent measles from spreading. But the total measles immunization coverage of U.S. kindergarteners has dropped below that, to 93 percent .

Many experts worry that the U.S. is at risk of losing its measles elimination status, which occurs if an outbreak lasts longer than a year .

“That threat is real,” says Patsy Stinchfield, a registered nurse and president of the National Foundation for Infectious Diseases. Even in states that do have at least 95 percent vaccination coverage, smaller communities within the state may be undervaccinated, Stinchfield says.

Here’s how to know if you’re protected.

How do you know if you have immunity to measles?

People born before 1957 are presumed to be immune to measles because they had it in childhood. Those born in 1957 or later, however, are likely protected only if they have been vaccinated. Initially, U.S. children received just one dose of the measles, mumps and rubella (MMR) vaccine, but that changed after a big measles outbreak that occurred from 1989 to 1991 and resulted in a reported 55,622 cases in the country. The outbreak killed 123 people and led to a congressional hearing .

Public health officials determined that a single MMR dose was not enough to prevent outbreaks. So in late 1989 both the American Academy of Pediatrics and the CDC began recommending that all children—including older children who received their MMR shot as toddlers—receive two doses of the vaccine.

“Most people born after 1975 would have received the second dose as part of their routine vaccinations,” says CDC spokesperson Jasmine Reed. “Most adults born between 1957 and about 1975 likely have had only one dose.”

How many doses of the measles vaccine are needed for immunity?

Vaccination against measles is highly effective in preventing infection. One dose of the MMR vaccine is 93 percent effective at preventing measles; it protects the vast majority of people. A second dose increases the effectiveness to 97 percent, capturing more of those who didn’t gain full immunity from the first dose.

How can you find your vaccination records?

You can start by asking your parents or former pediatrician, if that’s an option. If not, every state, as well as Washington, D.C., and most U.S. territories, maintains an immunization registry called an immunization information system (IIS). You can contact your state’s IIS to see if it has your immunization records. The CDC and the nonprofit group Immunize.org have additional tips on locating your vaccination records.

What if you’ve never been vaccinated against measles?

If you’re an adult born in 1957 or later who has never received an MMR dose, you should get two doses, four weeks apart , Stinchfield says. Or if you’re unsure if you were vaccinated, especially if you work in health care or childcare or in a long-term care facility, it’s worth making sure you’re protected by getting the vaccine.

If you’ve only had one dose of the measles vaccine, do you need another?

It depends on your risk factors.

When the CDC recommended that all children receive a second dose, it did not advise catch-up doses for most vaccinated adults. But the agency does recommend that the following adults get a second dose because they may be at higher risk during an outbreak: students in colleges, universities, trade schools and other post-high school institutions; health care workers born during or after 1957; and anyone traveling internationally.

Others who may want to consider a second dose during a measles outbreak are those who work around or have close contact with immunocompromised individuals who are unable to be vaccinated and those living in a group setting, such as barracks, says Erica Johnson , an infectious disease physician at Johns Hopkins Medicine. Stinchfield adds that those who work in a long-term care or childcare facility may also want to consider a second dose.

If you’re still concerned because there’s an outbreak in your area, Johnson recommends talking to your health care provider about your personal risk.

How can you find out if you have immunity to measles?

When you get a vaccine, your body produces proteins called antibodies that recognize the pathogen. “You’re basically teaching the immune system to remember a particular pathogen so that when the immune system sees that pathogen again, it remembers it and responds much more quickly,” Moss says.

You can get some sense of your immunity level with a blood test to check your antibody titers , or the concentration of antibodies in your blood. But that may not always be helpful. Often the results will be “indeterminate,” Stinchfield says. This could mean that you have insufficient immunity or that you do have protection but that the test did not show it. The immune system also has another vaccine response called cell-mediated immunity . It stores a memory of the pathogen in three other cell types: memory B cells, the factories where antibodies are made; memory T cells, which facilitate the immune response against the pathogen; and long-lived plasma cells in the bone marrow, which continually produce antibodies throughout a lifetime. Even if you have low antibody levels, these other immune cells can still protect you.

Drawing blood to check your antibody titers therefore may not give you the information you want to know. “It’s probably just as easy or easier to get an additional dose,” Moss says. Johnson and Stinchfield agree. “A third shot is not going to hurt anyone,” Johnson says.

Even if you’re vaccinated, can breakthrough infections happen?

In most cases, the vaccine confers lifelong protection. Secondary vaccine failure — in which someone develops the disease despite being immunized because of waning immunity—can occur, but it’s uncommon. Even in such cases of secondary vaccine failure , the illness people experience is very mild, Moss says. “They don’t get very sick because they have some protection.”

Who cannot get vaccinated against measles?

The MMR vaccine is a live vaccine. It contains an extremely weakened version of each virus that’s not potent enough to make most people sick but can still activate the immune system. Live vaccines are not recommended, however, for pregnant people or anyone who has an active immunodeficiency diagnosis (such as HIV) or who is on immunosuppressive therapies, such as chemotherapy, steroids or medications for certain rheumatologic conditions. The CDC has a longer list of other groups who should either delay the vaccine or skip it. If you’re uncertain whether a medication you’re taking makes it risky to get the vaccine, talk to the doctor who prescribed it.

There are no measles outbreaks in my area, but I plan to travel overseas. Do I need a measles vaccine dose?

The CDC recommends that any person planning to travel abroad should make sure before their trip that they have gotten two doses during their lifetime. “Measles transmission is different in different places, and if you’re uncertain about whether or not you’ve been adequately vaccinated for measles, that’s a good time to get another dose,” Johnson says.

Is there anything else I should do to protect myself?

If you’re a parent, make sure your kids are vaccinated, Moss says.

Ensuring both you and your children are immunized against measles is also important for protecting your community through herd immunity , in which a highly immune population makes it harder for a disease to spread and reach people who are not protected. “That’s how we protect immunocompromised people who can’t get vaccinated” and those who are too young to be vaccinated, Moss says.

It also protects those who are vaccinated but still at risk. If full vaccination is 97 percent effective, that means 3 percent of people “will have not made protective antibodies” even after two doses, Stinchfield says. “So we always have vulnerable people in our community.”
