Quarantine rules for international travel

Quarantine Requirements:

Some countries, including the US, have previously had quarantine requirements for incoming travellers, but these rules are now relaxed for vaccinated individuals. It is important to check the latest guidelines for your specific destination, as requirements may vary.

Vaccination Status:

Your vaccination status can impact your quarantine obligations. Many countries, like the US, Australia, and Greece, waive quarantine requirements for fully vaccinated travellers. However, the type of vaccine may also be a factor, as not all vaccines are deemed equal by every country. For example, Australia currently only accepts vaccines approved by its Therapeutic Goods Administration (TGA).

Testing Requirements:

Even if you are fully vaccinated, some countries may still require a negative COVID-19 test result, such as a PCR or antigen test, before granting exemption from quarantine. These tests often need to be taken within a specified timeframe before departure and may also be required upon arrival.

Proof of Vaccination:

It is essential to carry valid proof of your vaccination status when travelling internationally. Ensure you have multiple copies, both hard copies and digital versions, to present to the relevant authorities or airlines.

Dynamic Nature of Rules:

Quarantine and entry requirements can change rapidly, so staying informed is crucial. Regularly check for updates from official sources, such as government websites or health authorities, to ensure you comply with the current rules for your destination.

Additional Considerations:

Some countries or institutions may have specific requirements, such as digital passes tied to vaccination status, which can impact access to certain spaces or activities. It is also important to be mindful of any recommendations or guidelines provided by health organisations, such as the CDC, to help protect yourself and others during your travels.

Quarantine exemption for the fully vaccinated

Quarantine exemption policies for the fully vaccinated vary across different countries and regions. For example, in the US, the CDC states that fully vaccinated individuals who have received both doses of the Moderna or Pfizer vaccines or the single dose of the Johnson & Johnson vaccine do not need to quarantine if they come into close contact with someone infected with COVID-19, as long as they are asymptomatic. However, the CDC still recommends taking precautions such as wearing masks and practicing social distancing. Additionally, individuals returning from travel may need to follow different guidelines, as advised by the CDC's COVID-19 travel planner.

In the Czech Republic, as of August 23, 2021, fully vaccinated travellers were exempt from quarantine upon entry, regardless of their country of origin. However, it is important to note that quarantine rules can change rapidly, and travellers are advised to check the latest updates before planning their trip.

While being fully vaccinated reduces the risk of developing severe symptoms of COVID-19, it is important to remember that the vaccines are not 100% effective, and there is still a small chance of contracting the virus even after vaccination. As such, it is recommended to continue following safety guidelines, such as wearing masks, maintaining physical distance, and avoiding large gatherings whenever possible.

The definition of "fully vaccinated" may vary depending on the vaccine type and the time elapsed since the last dose. For the Pfizer and Moderna vaccines, individuals are typically considered fully vaccinated two weeks after receiving the second dose. It is important to stay updated with the latest recommendations from official health organizations and governments to understand the specific requirements for quarantine exemption.

Quarantine rules for specific countries

As of 2025, quarantine rules for vaccinated travellers continue to vary across countries. Here are the rules for some specific countries:

Canada

Fully vaccinated travellers are exempt from quarantine requirements in Canada. However, it is important to have a suitable backup quarantine plan in place before travelling, as border officials may deny quarantine exemption upon arrival. Travellers need to enter their quarantine information into the ArriveCAN app before departure. Additionally, all travellers aged five and older, regardless of vaccination status or citizenship, must provide proof of a negative COVID-19 test taken within 72 hours before arrival in Canada.

United Kingdom

The United Kingdom has specific isolation measures based on travellers' vaccination status and country of departure. Fully vaccinated travellers from most countries are generally not required to quarantine upon arrival. It is recommended that they take a COVID-19 test before departure and within two days of arrival. However, travellers should regularly check official UK government websites for updates as rules can change.

Germany

Germany's quarantine rules depend on federal state regulations. As of January 2025, travellers with proof of vaccination or a recent recovery certificate (issued within the last six months) may be exempt from certain requirements. It is advisable to check for updates before travelling to Germany as circumstances can shift.

Romania

International travellers arriving in Romania, including Americans, can skip the 14-day quarantine requirement if they provide proof of vaccination completed at least 10 days before arrival or proof of recovery from COVID-19. Children aged 3 and under are exempt, while those aged 3 to 16 must present a negative COVID PCR test taken within 72 hours of travel.

New Zealand

New Zealand has relaxed its previous restrictions. Travellers can now enter without mandatory isolation by showing proof of full vaccination and a negative test result within a specified timeframe.

It is important to note that travel restrictions can change suddenly, and travellers should always check the latest information from official government sources before planning their trips. Rules may vary based on factors such as vaccination status, testing requirements, country of departure, and local health conditions.

Quarantine and testing after exposure

Quarantine and testing requirements after exposure to COVID-19 vary depending on vaccination status and location. Here is some information regarding quarantine and testing after exposure to COVID-19 for individuals who are fully vaccinated:

Quarantine Guidelines:

In the United States, the CDC states that fully vaccinated individuals do not need to quarantine if they are exposed to someone with COVID-19. However, they should still take precautions such as wearing a mask and practicing social distancing. For individuals living in congregate settings, such as nursing homes, the Department of Health recommends quarantining after exposure, regardless of vaccination status.

In the Czech Republic, as of August 23, 2021, fully vaccinated travellers were exempt from quarantine upon arrival. However, it is important to note that travel guidelines can change, and individuals should refer to the latest official sources for updated information.

Testing Guidelines:

Fully vaccinated individuals who have been exposed to COVID-19 should follow testing guidelines. It is recommended to wait 3-5 days after exposure before getting tested, as testing too early may yield a false negative result. During this time, it is important to monitor for any COVID-19 symptoms, such as fever, shortness of breath, or other symptoms associated with the virus. If symptoms develop, seek emergency care if they are severe or life-threatening.

After exposure, fully vaccinated individuals should wear a mask in public indoor settings for 14 days or until they receive a negative test result. This precaution helps prevent the potential spread of the virus, even if the individual is asymptomatic.

Quarantine and mask-wearing

For example, in the US, the CDC advises that fully vaccinated people exposed to COVID-19 do not need to quarantine if they meet certain conditions. They must be fully vaccinated, which means having received both doses of the Moderna or Pfizer vaccines or the single dose of Johnson & Johnson within the past three months. Additionally, it must have been at least two weeks since their last dose, and they should not be experiencing any COVID symptoms. However, if a vaccinated person develops symptoms, they should quarantine and get tested. The CDC recommends that people in this situation watch for a fever, shortness of breath, or other COVID-19 symptoms, and get tested immediately if symptoms develop. It is important to note that the CDC still recommends taking precautions, such as wearing a mask and practicing social distancing, even for vaccinated individuals.

In the Czech Republic, as of August 23, 2021, fully vaccinated travellers were exempt from quarantining upon entry into the country. However, this information was difficult to find, with one traveller expressing confusion over conflicting information from the Czech and UK governments. This highlights the importance of staying up-to-date with the latest guidelines, as quarantine and mask-wearing requirements can change rapidly.

While vaccination has reduced the need for quarantining in many parts of the world, it is important to follow the latest guidelines from local health authorities. Quarantine and mask-wearing requirements can vary by country and are subject to change as new variants emerge and the situation evolves. Staying informed helps protect individuals and communities from the spread of COVID-19.
