Visiting students
Incoming students should include their COVID-19 vaccine information on their Yale Vaccination Record form and submit it to Medicat,  Yale's online immunization portal, along with all of their documentation (including their government-issued COVID-19 vaccination card). 

The university requires all students, other than those with approved medical exemptions, to be fully vaccinated and to have obtained a booster shot if they are eligible by the time they arrive on campus for Summer 2022.

COVID-19 Vaccine Exemption Requests

The university’s COVID-19 vaccine requirement is critical for the health of our community and safe in-person university operations. Faculty, staff, postdoctoral/postgraduate trainees, and students may request exemptions from the vaccine/booster requirement for medical reasons.

Anyone requesting an exemption must access, complete and upload the request forms through the Yale Vaccine Portal (the portal). Once completed and uploaded on the portal, requests are submitted to the university’s COVID-19 vaccine exemption review committees. Information about the public health requirements that are applicable to individuals who have exemptions may be found on the Vaccine Policy site.
