Vaccinations Provided to the Medicaid and CHIP Population under age 19

Metadata Updated: June 27, 2024

This data set includes monthly counts and rates (per 1,000 beneficiaries) of vaccinations provided to Medicaid and CHIP beneficiaries under age 19 (as of the first day of the month), by state. The following vaccinations are included: Chickenpox, DTaP, HPV, Hepatitis A, Hepatitis B, Influenza, MMR, Meningococcal, Meningococcal B, Pneumococcal conjugate, Pneumococcal polysaccharide, Polio, Rotavirus, Tdap, and all vaccinations.

These metrics are based on data in the T-MSIS Analytic Files (TAF). Some states have serious data quality issues for one or more months, making the data unusable for calculating vaccination measures. To assess data quality, analysts adapted measures featured in the DQ Atlas. Data for a state and month are considered unusable if at least one of the following topics meets the DQ Atlas threshold for unusable: Total Medicaid and CHIP Enrollment, Procedure Codes - OT Professional, Claims Volume - OT. Please refer to the DQ Atlas at for more information about data quality assessment methods. Cells with a value of “DQ” indicate that data were suppressed due to unusable data.

Some cells have a value of “DS”. This indicates that data were suppressed for confidentiality reasons because the group included fewer than 11 beneficiaries.
