The FDA authorized and the CDC approved in September 2022 updated (bivalent) versions of the Pfizer and Moderna COVID-19 vaccines. The updated vaccines offer protection from the original COVID-19 virus and the omicron variant that is currently circulating. The bivalent Moderna and Pfizer COVID-19 vaccine is authorized for administration at least 2 months following completion of primary or booster vaccination for anyone aged 6 months and older. Learn more about the updated omicron doses from CDPHE.

Standard COVID-19 Vaccine Dosing Schedules

COVID-19 vaccine recommendations are based on your age, the vaccine you first received, and the time since your last dose. Children get a smaller dose of COVID-19 vaccine than teens and adults, based on their age group. Updated COVID-19 boosters can both help restore protection that has decreased since previous vaccination and provide broader protection against newer variants. The updated, or bivalent boosters, target the most recent Omicron subvariants, BA.4 and BA.5, that are more contagious and more resistant than earlier strains of Omicron.

COVID-19 Vaccine Dosing Schedules for People who are Immunocompromised

If you have a moderately to severely weakened immune system, you are at an increased risk of severe COVID-19 illness and death. Additionally, your immune response to COVID-19 vaccination may not be as strong as in people who are not immunocompromised. For those reasons, additional doses are recommended.

For more details about vaccination schedules for those who are immunocompromised, go to the CDC's COVID-19 Vaccines for People Who Are Moderately or Severely Immunocompromised webpage.
