Stay Up to Date with COVID-19 Vaccines and Boosters

You are up to date with your COVID-19 vaccines if you have completed a COVID-19 vaccine primary series and received the most recent bivalent dose recommended for you by the CDC.

Vaccine recommendations are based on your age, the vaccine you first received, and time since last dose. People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines.

Updated bivalent vaccines are now recommended for anyone six months old and older. Per the CDC, bivalent mRNA vaccines are not authorized at this time for primary series doses with the following exception: children ages six months to four years who receive two primary series doses of a monovalent Pfizer-BioNTech vaccine should receive a bivalent Pfizer-BioNTech vaccine as their third primary series dose. Consult with your primary care manager on availability and the best options to help protect you and your loved ones from severe illness, hospitalization, or death from COVID-19.
