Booster Shots and Additional Doses
A booster shot is administered when a person has completed their initial vaccine series and protection against the virus has decreased over time. Certain groups of people, including older adults, are eligible to get a booster shot at least 6 months after completing their initial vaccination series. Learn more about who is eligible for a COVID-19 vaccine booster shot.
An additional dose is administered when a person may not have built the same level of immunity to their initial vaccine series as someone who is not immunocompromised. CDC recommends that people with moderately to severely compromised immune systems receive an additional dose at least 28 days after completing their initial vaccine series.

Vaccination Card and Booster Shots
At your first vaccination appointment, you should have received a vaccination card that tells you what COVID-19 vaccine you received, the dates you received it, and where you received it. Bring this vaccination card to your booster dose vaccination appointment.
