UPDATED MAY 20, 2022
Booster doses are now available to all Missourians age 5+.
The CDC recommends COVID-19 booster doses for:
- Pfizer recipients (ages 5+) 5 months after completing primary series
- Moderna recipients (ages 18+) 5 months after completing primary series
- J&J recipients (ages 18+) 2 months after single dose
Some individuals are eligible for a second booster dose 4 months after their first booster:
- Pfizer recipients (ages 50+)
- Moderna recipients (ages 50+)
- J&J recipients who received an mRNA booster (ages 50+)
- J&J recipients who received a J&J booster (ages 18+)
- Immunocompromised people (ages 12+)
Some immunocompromised folks should get an additional primary shot.
After completing the primary series, some moderately or severely immunocompromised people should get an additional primary shot. If you are eligible for an additional primary shot, you should get this dose first before you get a booster shot.
The CDC recommends COVID-19 additional doses for:
- Pfizer recipients (ages 5+) who are moderately to severely immunocompromised after 28 days
- Moderna recipients (ages 18+) who are moderately to severely immunocompromised after 28 days
- No additional primary shot is recommended for J&J recipients at this time
If you would like to receive your booster or additional dose, you can make an appointment or walk into one of our clinics. Visit our clinic calendar to learn more about vaccine brands offered and clinic hours / locations.
