Immunize Colorado has updated a measles data visualization tool first released in 2018 with data from the 2019-20 school year. The tool, a data dashboard, demonstrates the potential impact that measles outbreaks could have on students and schools across Colorado counties and school districts. These dashboards can be used to look up the percent and number of students that would be potentially excluded from attending school at the county and school-district level either due to claiming an MMR vaccine exemption or having an incomplete or missing vaccination record on file. Statewide, nearly 45,000 Colorado students would potentially be excluded from school for up to 21 days in the case of a measles outbreak.
During the 2019-20 school year, 91% of Colorado kindergarteners were vaccinated for MMR, an increase of 3.7% from the previous year. However, we have also seen pediatric immunization rates drop significantly due to the COVID-19 pandemic since the start of 2020, a drop that is not reflected in the current available data. The full effects of this drop in routine vaccination rates will not be seen until the 2020-21 school immunization data is released.
