Colorado’s school vaccination rate hovers below level needed for herd immunity

June 17, 2024

Colorado’s vaccination rate held steady in the most recent school year, but pockets of the state remain vulnerable to outbreaks of measles and other diseases.

Last school year, 92.1% of children from kindergarten to 12th grade had all of their required shots or a valid exemption, which was virtually unchanged from the 2022-2023 school year. Kindergarteners had lower compliance rates, with 90.1% either up to date on their shots or holding an exemption.

About 93.6% of all schoolchildren had their combined measles, mumps and rubella shots, which are among the most important because a person with measles can infect nine out of 10 unvaccinated people they come across, said Susan Lontine, executive director of Immunize Colorado. Only 88% of kindergarteners had been vaccinated against measles, though.
