To the members of the MIT community,

On Monday, the Centers for Disease Control and Prevention (CDC) strengthened its recommendations to advise that all adults 18 and older who are six months past their last Covid-19 vaccine (two months for Johnson & Johnson/Janssen) SHOULD receive a Covid-19 booster vaccination. The evidence is clear: Vaccines are the most powerful weapons we have in combatting this virus. It is also clear that booster doses increase immunity against infection, and help reduce asymptomatic transmission. This is especially important in light of the recent identification of Omicron, a new variant of concern.

Because of the heightened risks posed by travel, MIT is now requiring all booster-eligible community members participating in MIT-sponsored travel beginning on December 17 to receive a Covid-19 booster vaccine before their travel commences. If you are still in the six-month window (two months for Johnson & Johnson/Janssen) since your last dose, the requirement takes effect two weeks after you become eligible.

If you have already received a Covid-19 booster dose:

All MIT community members can now upload evidence of their booster doses. Visit or update your MIT Atlas app to upload your proof.

If you have yet to receive a Covid-19 booster dose:

MIT Medical will be holding a series of booster clinics by appointment only in Walker Memorial (Building 50) over the coming weeks. These clinics are free to Covid Pass participants (including all students, faculty, and staff) and MIT Medical patients, and you must book an appointment online. If you are working entirely remotely (not in Covid Pass) and are not an MIT Medical patient, you may still come to MIT to get your booster. All eligible individuals can come to the clinic regardless of whether they plan to engage in MIT-sponsored travel.

Clinics will offer mRNA vaccine from different manufacturers (Pfizer and Moderna) on different days. You can safely receive either vaccine regardless of the type of Covid-19 vaccination(s) you received initially.

Because we are expecting high demand, please book your appointment as soon as possible.

Again, to be eligible for a booster dose, you must be 18 years of age or older. It must be six months or longer since your final Pfizer or Moderna vaccine, or at least two months since your Johnson & Johnson/Janssen vaccine.

Proof of prior vaccination is required to participate in the clinic. Please bring your Covid-19 vaccination card to the clinic.

If you cannot make it to campus, limited booster vaccine appointments are available at local pharmacies, but you may need to wait a few weeks to receive a booster at a pharmacy due to high demand.

A few additional points you need to know:

  • We are offering booster doses at these clinics — not third doses. If you have a condition that requires a full third dose of vaccine, speak with your personal clinician to receive your required immunization. If you receive a third dose, you can upload proof of that immunization instead of a booster.
  • If you already have an approved exemption, no further action is required. If you have an approved medical or religious exemption on file, you do not need to reapply.
  • We will also be administering a limited number of flu vaccines at these clinics. Those who make an appointment for a booster may safely receive both a Covid-19 booster and a flu vaccine at the same time while supplies last. Students who get a flu vaccine at the clinic will have their proof of vaccination recorded automatically to complete the flu vaccine requirement.
