Do you need a COVID-19 Vaccine booster?

COVID-19 vaccine booster shots are recommended for all adults aged 18 years and older who have completed their initial 2-dose series of the Pfizer or Moderna vaccine at least six months ago.

COVID-19 vaccine booster shots are also recommended for those who received the Johnson & Johnson COVID-19 vaccine two or more months ago and are 18 years and older.

Eligible individuals may choose which vaccine they receive as a booster dose. Some people may have a preference for the vaccine type that they originally received, and others may prefer to get a different booster. The CDC's recommendations now allow for mix and match dosing for booster shots.

All three vaccine types are safe and effective. However, if you have questions about which vaccine to receive, please contact your physician.

For more information, visit the CDC.

We will continue to monitor federal and state guidelines for more information on COVID-19 vaccine booster shots for other populations.
