While mixing doses during a primary series is not recommended at this time, you may choose to receive a different vaccine for your booster shot if you have completed a primary series and are eligible for a booster. CDC’s recommendations allow for this type of mix and match dosing for booster shots.
For your primary vaccine series, you should get the same kind of vaccine for both doses to be as protected as possible. If you received one dose of your primary series and wish to complete your primary series with a different vaccine, please speak with your physician. You can’t make an appointment to receive another type of vaccine in your primary vaccine series, but most vaccination clinics allow walkup appointments, or you can request a different type of vaccine onsite, if available. Be sure to take a physician’s order with you, but please know it is up to the clinic to decide if it will honor the order.
The CDC recommends that people stay up to date with their vaccinations and get boosted when eligible. Use CDC’s COVID-19 vaccination schedule for people who are moderately or severely immunocompromised to make sure you are up to date.
