HB 2755 increases transparency and reporting on epidemiological data and immunization exemptions in Texas. It mandates the Texas Department of State Health Services to publicly report outbreaks of vaccine-preventable diseases and de-identified immunization exemption statistics. It also requires public schools and school districts to submit annual vaccination rate reports, including the number of students with exemptions due to medical reasons or conscience objections. This data must be posted online for public access. The bill applies to school years beginning in 2025​.
