Booster shots and additional cans
A booster vaccination is given when a person has completed their first series of vaccinations and protection against the virus has diminished over time. Certain groups of people, including older adults, are entitled to a booster vaccination at least 6 months after completing their first series of vaccinations. Find out more about who is eligible for a COVID-19 booster vaccination.
An additional dose is given when a person may not have developed the same immunity to their initial series of vaccinations as a person 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 first series of vaccinations. Learn more about COVID-19 vaccines for moderately to severely immunocompromised people.
Vaccination certificate and booster vaccinations
At your first vaccination appointment, you should have received a vaccination card that tells you which COVID-19 vaccine you received, the date you received it and where you received it. Bring this vaccination certificate with you to your appointment for a booster vaccination.
