Vaccine & booster requirements

The University is requiring COVID-19 vaccinations for all Harvard community members and COVID-19 boosters 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 receive and verify your COVID-19 booster is January 31. If you’re not yet eligible to receive your booster, your deadline to receive and verify your booster will be 30 days after you become eligible.

  • Schedule your booster

    If you’re unable to get a booster before you return to campus, you will not be barred from entering campus. You will, however, be expected to arrange for the booster as soon as possible. If you received your primary vaccine series outside the United States, you should seek a booster 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.

  • 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.
