Colorado public health officials have worked for years to increase immunization rates for school kids, with a particular concern about the percentage of kindergarteners who are not getting the measles vaccine.
They’ve offered free shots, sent letters and launched radio ads. Yet, the state’s vaccination rate is dropping.
Statewide, 86.8% of kindergarteners were vaccinated against measles, mumps and rubella last year. That’s the lowest since 2017, erasing any gains the state had made in the prior five years.
