Vaccine & booster requirements

The University is requiring COVID-19 vaccinations for all Harvard community members and one COVID-19 booster for all eligible community members. This includes students, faculty, staff, and researchers. Vaccines and boosters must be FDA- or WHO-authorized. If you’re unable to access an FDA- or WHO-authorized vaccine, the University will offer vaccination with an mRNA vaccine to all Harvard affiliates with a Harvard ID.

  • Booster deadline

    The deadline to verify that you have received a COVID-19 booster is 30 days after you become eligible to receive the dose.

  • Schedule your booster

    Those without a booster shot will not be barred from entering campus, but will, however, be expected to arrange an appointment for their booster as soon as possible. If you received your primary vaccine series outside the United States, you should seek a first booster dose with any WHO-approved vaccine that is available to you (mixing of brands is acceptable). HUHS is hosting booster clinics in the coming weeks. See the scheduling options.

  • Verify your booster

    See the step-by-step guidance to verify your booster through the HUHS Patient Portal. Beginning February 11, the registrar will place an immunization holds on the accounts of students who are eligible for a booster but have not submitted proof of vaccination. The hold will be removed upon verifying vaccination status with HUHS. For more information, visit the HUHS immunization page.

  • Second booster doses

    On March 29, the FDA approved usage of a second booster dose of either the Pfizer-BioNTech or the Moderna vaccine for individuals 50 years of age and older, and individuals 12 years of age and older with certain immunocompromising conditions. Members of the community who receive their optional second booster dose can submit proof in the HUHS portal.

  • Exemptions

    If you have an approved exemption for the vaccine, you don’t need to submit additional documentation for a booster exemption.

  • Federal vaccination mandate

    Consistent with federal guidance, all Harvard employees, including those who are on 100% remote work status, must be fully vaccinated unless they have an approved exemption. Employees do not have the option to opt for additional testing instead of vaccination.

Plan for your vaccine and booster


Already received the vaccine and booster?

Keep your vaccination card safe and make a copy for your files. You never know when that card might be required in the future (for in-person participation in activities, international travel, etc.).

Community members are advised to complete their vaccination and booster (if eligible) as soon as possible and must submit verification to HUHS. Visit the University’s Verify Your Vaccination & Booster webpage to learn how to submit your verification.
