Students are required to submit proof of receiving at least a single dose of bivalent COVID-19 vaccine, either as booster received on or after September 2, 2022 or as a single dose received on or after April 19, 2023, regardless of previous doses. If you already received a Pfizer or Moderna booster after September 2, 2022, you received a bivalent dose. Any Pfizer or Moderna dose received after April 19, 2023, regardless of previous doses received, is bivalent. More information on staying up to date with COVID-19 vaccines is available from the CDC.

If Vax Viewer previously showed your status as boosted and now shows that you need a booster, this indicates the booster dose you reported does not qualify as bivalent and you need to submit documentation of a bivalent dose.
