There are currently three vaccines authorized by the U.S. Food and Drug Administration under Emergency Use Authorization. Two are two dose vaccines, requiring a booster at 21 days and 28 days, respectively. The third is a one-dose vaccine.

Recipients must receive the same vaccine for both the first and second doses. Your vaccination provider will give you a card with the manufacturer's name and other critical information you will need for a second dose. If you miss your second dose, please get it as soon as possible after the 21- or 28-day recommendation.
