If you are already fully vaccinated, you can’t make an appointment to receive another type of vaccine as your primary vaccine series, but most vaccination clinics allow walkup appointments, or you can request a different type of vaccine onsite, if available. Since your clinical team is best positioned to determine the appropriate timing of vaccination, it is best to get a physician’s order to receive a different vaccine. Be sure to take the 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.
