What if I received a first dose of a WHO-authorized vaccine in my home country, but wasn’t able to get the second dose before leaving for UB?

The recommendations for people vaccinated outside of the United States depend on the vaccine(s) received for the primary series, whether the primary series was completed, and whether a booster dose was received

People who initiated vaccination outside of the United States are considered to be up to date with their COVID-19 vaccines when they have completed the recommended actions described in CDC interim guidance for people who received COVID-19 vaccine outside the United States.

Students who completed a WHO-EUL COVID-19 vaccine series, and then got a WHO-EUL vaccine as a booster should not repeat the booster dose according to the CDC.
