The vaccinations you receive in your childhood often fade over time, and many others require routine boosters to maintain their safeguards. To continue the protection for St. Charles County’s adult population, our department offers all recommended adult vaccines to those ages 19 and older through our Adult Immunization Program (AIP).

To schedule an appointment, please call 636-949-1857.

There is a minimal fee for these vaccines (which may be covered by your insurance provider). For those ages 19 and older who meet Section 317 program eligibility guidelines, these vaccines may be received at no charge.

Adult Section 317 Program - Eligibility Requirements

To qualify, an individual must be age 19 or older and meet one of the following criteria:

  • Have no health insurance.
  • Have health insurance that does not cover 1 or more vaccines.
  • Have vaccine requirements in response to a declared event.
