You or your child will need four doses.
Schedule the second dose four weeks after the first dose.
Schedule the third dose at least four weeks after the second dose.
The fourth dose should be an omicron dose. Schedule the fourth dose at least two months after the third dose.
If you or your child already received booster doses of the original formulation of the COVID-19 vaccine, schedule the omicron dose at least two months after your most recent dose. It doesn’t matter how many original booster doses you already received – you should get an omicron dose as well.
People aged 6 years and older can get either a Pfizer or Moderna omicron dose, regardless of which types of vaccines you previously received. There is no preference. Children 5 years of age can only get Pfizer’s omicron dose.
- Getting Novavax for your fourth dose
Adults aged 18 years and older who haven’t received any booster doses yet and either can’t or would prefer not to get a Pfizer or Moderna omicron dose can get Novavax for their fourth dose. Schedule this fourth dose six months after your third dose. This dose is the same formulation and dosage as the doses in the Novavax primary series.
