WV SB992

Requires the West Virginia Secretary of Health to conduct a retrospective, longitudinal study comparing health outcomes between vaccinated and unvaccinated children in the state

Study must examine associations between vaccination status and chronic conditions including respiratory diseases, autoimmune disorders, neurodevelopmental diagnoses, metabolic disorders, and healthcare utilization frequency

Data sources include existing Medicaid claims, state immunization registry, hospital discharge records, and vital records—no new personal health data collection is required

Report on findings must be submitted to the Governor, legislative leadership, and the Joint Committee on Health and Human Resources within eight months of the law taking effect

Study is explicitly observational in nature and may not claim causal conclusions; the Department must acknowledge limitations related to data completeness and potential confounding factors
