COVID-19 Vaccine Requirement FAQs

Why is Harvard requiring vaccination for all Harvard community members?

A high vaccination rate across the Harvard community is a critical aspect of our on-campus activity, public health conditions permitting. To reach the high levels of vaccination needed to protect our community, Harvard is requiring COVID-19 vaccination for all Harvard community members, including students, faculty, staff, and researchers, who will have any on-campus presence. Exceptions will be provided only for medical or religious reasons. Note that unvaccinated individuals may be subject to additional public health measures (e.g., masking, testing) above and beyond what is required of vaccinated individuals. Updates and information regarding the University’s vaccine requirement can be found on the University’s vaccine webpage, and additional details will be added when available.

Community members are advised to complete their vaccination as soon as possible and submit verification of vaccination to HUHS.  Please see the University’s Verify Your Vaccine webpage for updates and additional information.

Students should plan to be fully vaccinated before returning to campus, meaning that at least two weeks have passed since the final dose of an FDA-authorized or approved vaccine (currently Pfizer, Moderna, or Johnson & Johnson) or vaccines that have been authorized for emergency use by the World Health Organization (e.g., AstraZeneca/Oxford). You can read more about the requirement and how to submit documentation on the Harvard University Health Services (HUHS) website.  

What vaccines will Harvard accept?

All vaccines authorized by the FDA or the World Health Organization (WHO) will meet the University’s vaccine requirement. The list of vaccines authorized by WHO is updated regularly. We strongly encourage you to be vaccinated when you can with the vaccine that is available to you. Protection from vaccination is helpful while traveling.

Should I be re-vaccinated if I got the vaccine outside the U.S.?

I received a COVID-19 vaccine in another country (not one of the approved in the United States or by the WHO) and will be coming to Harvard. Should I be re-vaccinated when I get to the U.S.?

If you are already vaccinated, you do not need to get any additional vaccines right now. If the vaccine you received is not authorized by WHO by the time you arrive, HUHS will offer you an FDA-authorized vaccine. Guidelines and recommendations are continually updated based on research. It is important to stay updated by reading all communication coming from Harvard about the vaccine requirement.  Harvard’s coronavirus webpage, will also contain the most up-to-date information. 

I was unable to get vaccinated at home before traveling to campus. Can I be vaccinated when I arrive at Harvard?

If you are in the U.S., vaccine appointments are now readily available. Please find vaccine sites at or through at You should make every attempt possible to complete your vaccination before you arrive at Harvard. For those individuals who are not fully vaccinated when they arrive on campus, travel quarantine and testing upon arrival will be required per the university guidelines.

I received one dose of a two-dose vaccine in another country. Can I received my second dose at Harvard?

The only vaccines available for distribution in the U.S. are Pfizer, Moderna, and Johnson & Johnson. If your first dose was not one of these three, recommendations will be made on a case-by-case basis. We still advise you to get whatever vaccine is available to you, so that you can have some protection during travel. You may contact HUHS directly by email at for individual recommendations.

If I have not been vaccinated, where can I get vaccine sources available to me?

If you have not been vaccinated and would like information on vaccine sources available to you, please visit the University’s vaccine webpage, which includes links to resources to help you plan your vaccine and schedule an appointment at a location near you. 

What about international students who may have trouble accessing vaccine before they travel to campus?

For international students and any others unable to access an FDA- or WHO-authorized vaccine, vaccinations can be obtained. Please note, however, that these students may be subject to additional requirements, such as more frequent testing, until they are considered fully protected by a vaccine. Students may contact HUHS with questions.

Will there be more guidance coming for international students?

For instance, if they can't get vaccinated before they travel and will need it when they arrive, should they just be in touch with HUHS directly? Do they have to advise their School? Or HIO?

International students are encouraged to receive a COVID-19 vaccine as soon as possible. All vaccines authorized by the World Health Organization (WHO) will meet the University’s vaccine requirement.

How will Harvard verify if a community member is vaccinated?

You can now upload a copy of your COVID vaccination card to your HUHS Patient Portal. If you have already submitted your COVID vaccination documentation to you do not need to resubmit to the Patient Portal.

June 11th Immunization Submission Due Date and Registration Holds Update

We understand that WHO-approved COVID-19 vaccines, as well as other required vaccines, may be difficult to acquire right now. Please submit any immunization documentation that you have at this time to the Patient Portal. Health Services staff will verify what you have submitted and will let you know if you are missing anything. Vaccine documentation can and should continue to be submitted after June 11th as you receive any required, missing vaccinations. Due to the large volume of submissions we are receiving, it can take 2 to 3 weeks for the Portal to be updated and reflect your submission. We encourage the submissions earlier rather than later so that we can process them in time for class registration.

Registration Holds are not activated at this time. Secure messages announcing the date on which holds will be activated will be sent to all non-compliant students. In the event you have a Registration Hold due to an outstanding immunization, Health Services staff will work with you to provide information and options for you to receive the immunizations you need in order to register for classes.

Faculty and staff returning from an approved leave should submit their vaccination attestation or exemption request prior to returning to campus.

I'm a Person of Interest (POI) at the University but can't log into the Pt Portal to upload my vaccination record. What do I do?

Only Persons of Interest (POIs) who have been authorized to be on campus and have been enrolled in a testing cadence in Crimson Clear are eligible to enter their information directly via the Patient Portal. If the POI is not in a testing cadence, they will not have an Electronic Medical Record with HUHS and, therefore, will not be able to login to the portal. 

A POI can determine if they have a testing cadence by logging into Crimson Clear. If a POI does not have a testing cadence, they should contact their Local Test Coordinator.

Is there any charge to get vaccinated?

There is no cost to you to receive the vaccine, but your insurance company may be billed for the administration of the vaccine, which is covered by your insurance. There are a number of places to get vaccinated through local pharmacies and state-run or community-based clinics. Additional information on vaccination options as well as links may be found on the University vaccine site and the vax finder.

Do I need to remain in the asymptomatic testing program if vaccinated?

Yes, we are requiring regular testing of all community members regardless of vaccination status. Our testing program is one of our key protocols for assessing the overall health and safety of the community. Color will send you notifications of when it is your day to test. You can find up-to-date information on testing frequency on the coronavirus site.

Do I need to quarantine as a close contact if I've been vaccinated?

Individuals who have been fully vaccinated and submitted their vaccination information to HUHS will no longer need to quarantine if they are identified as a close contact and their last exposure to a positive person was later than two weeks after their vaccination (the second of two doses for two-dose vaccines, or the single dose for one-dose vaccines) is complete. Vaccinated individuals are still expected to participate in contact tracing efforts as requested by HUHS.

Who can I contact with questions about my specific situation?
