Coronavirus Frequently Asked Question

What does “fully vaccinated” mean?

Does it refer to one or two shots depending on the vaccine? Does it include a period of time after the dose for an immune response?

A person is considered “fully vaccinated” when two weeks have passed since they completed a COVID-19 vaccine series (for example, one dose of the Janssen/J&J vaccine, or two doses within no more than 12 weeks of the Moderna or Pfizer vaccine) as well as any boosters consistent with manufacturer’s instructions and applicable agency approval, authorization, or listing.

All vaccines approved by the World Health Organization are accepted.
