Clinical studies show vaccination is safe and highly effective in:

  • Preventing COVID-19 infection.
  • Reducing the risk for severe complications and hospitalization.

St. Charles County Public Health is authorized by the Missouri Department of Health and Senior Services (DHSS) to administer free COVID-19 vaccinations to those ages 6 months and older. This includes first, second, third and booster doses of the Pfizer/BioNTech (Pfizer), Moderna or Janssen (Johnson & Johnson) vaccines to those who are eligible.

Bivalent COVID-19 Booster Vaccinations

In September 2022, DHSS, the U.S. Food and Drug administration (FDA) and the Centers for Disease Control and Prevention (CDC) authorized the administration of the Pfizer and Moderna bivalent COVID-19 booster vaccinations. Eligible individuals for the bivalent booster include those who have completed their primary vaccination series or received a booster dose for the Pfizer, Moderna or Janssen vaccines at least two months prior. The bivalent Pfizer booster is authorized for individuals ages 12 and older, while the Moderna booster is authorized for those ages 18 and older. Eligible individuals may choose to receive either of these booster doses, regardless of which primary series or original booster dose they had previously.

Pediatric COVID-19 Vaccinations

In June 2022,  DHSS, the FDA and CDC authorized the administration of the Pfizer and Moderna COVID vaccines to those ages 6 months and older. Parents and caregivers should speak with their pediatrician to determine which vaccine is preferred.

Schedule a COVID-19 Vaccine Appointment

Individuals ages 6 months and older who have not yet been vaccinated, who have not completed their primary vaccination series or who are seeking booster vaccinations may schedule a vaccination appointment with the St. Charles County Department of Public Health (SCCDPH) online. PLEASE NOTE: Individuals ages 17 and younger must be accompanied by a parent or guardian at the time of the vaccination.
