  • Childhood Vaccinations Information

    The Texas Vaccines for Children (TVFC) program provides low-cost or free vaccines to eligible children from birth through 18 years of age who meet one or more of the following criteria:


    • Eligible for participation in the Medicaid program
    • Enrolled in the Children's Health Insurance Program (CHIP)1
    • American Indian or Alaska Native (As defined by 25 U.S.C. 1603)
    • Uninsured Children: Children who do not have health insurance
    • Underinsured: Children who have commercial (private) health insurance, but
    1. Coverage does not include vaccines; or
    2. Covers only selected vaccines (TVFC-eligible for non-covered vaccines only); or
    3. Health insurance covers all vaccines, but the plan has a fixed dollar limit or cap on the amount that it will cover for vaccines (TVFC-eligible once fixed dollar amount or cap is reached).

    Though children whose insurance pays for vaccines do not qualify for TVFC vaccine, CHIP children do qualify by special arrangement.


    Underinsured children must be seen by a Federally Qualified Health Center (FQHC), Rural Health Clinic (RHC), or deputized clinic.
