Immunize Colorado’s Legislative District Data Dashboard and supplemental fact sheets provide important information on childhood immunization coverage to help legislators and constituents in each legislative district understand the level of vaccine protection in their community and identify areas for improvement. Using data released annually by CDPHE, Immunize Colorado develops the dashboard and fact sheets customized to all 65 House and 35 Senate districts in Colorado. These tools contextualize school- and student-level protection from vaccine-preventable diseases, vaccination rates across schools, and more. We encourage advocates to use them to inform local discussions on immunization-related policy and in meetings with legislators.
