Pfizer-BioNTech and Moderna have each created an updated booster dose formula designed to protect against original strains of the virus, as well as Omicron variants that cause most new infections. Updated boosters of Pfizer-BioNTech and Moderna contain two formulas that boost immunity against the original coronavirus strain and also protect against the newer Omicron variants.
The CDC recommends eligible people 6 months and older receive an updated, bivalent Pfizer or Moderna vaccine that offers better protection against variants. Some people, like those who are immunocompromised or over 65, are eligible for a second bivalent dose.
The latest CDC recommendations on booster doses help to ensure more people across the U.S. are better protected against COVID-19. The best way to protect yourself from COVID-19 is to get vaccinated and boosted if eligible. Vaccination and boosting are particularly important for individuals more at risk for severe COVID-19, such as older people and those with underlying medical conditions.
The CDC has guidance for everyone 6 months and older based on age and medical condition.
