COVID-19 vaccine updates and recommendations for all doses and demographics.

The FDA has recommended the use of bivalent Moderna and Pfizer-BioNTech COVID-19 vaccines for all doses administered to residents at least 6 months old, while monovalent COVID-19 vaccines are no longer recommended for use nationwide. The updated vaccines and boosters are bivalent, which means they are created with two strains of the virus and include the newer omicron variant strains. The CDC’s Advisory Committee on Immunization Practices supports the recommendations. Alternatives to mRNA COVID-19 vaccines are available, and the CDC’s recommendations for monovalent Novavax or Johnson & Johnson’s Janssen COVID-19 vaccines have not changed.
