Get your flu shot
It’s always important to get a flu shot. But with COVID-19, it’s even more important this year. Flu is a dangerous disease, but it’s even more deadly when combined with the risks associated with COVID-19.
Our 2021 Cambridge Campus walk-in flu clinic has ended.
The 2021–22 flu vaccine offered at MIT is quadrivalent, protecting against two strains of influenza A (H1N1 and H3N2) and two strains of influenza B.
Active flu strains are different each year, so even if you got a flu shot last year, you still need to get this year’s vaccine. More information about this year’s vaccine is available from the CDC (Vaccine Information Statement) and the Commonwealth of Massachusetts (Massachusetts Immunization Information System).
