At Bellbrook High School in Bellbrook, Ohio, 98% of 12th graders had all required vaccines entering the 2016-17 school year. Of 232 12th graders, zero were medically exempt from vaccines and four had exemptions for religious or personal beliefs. The information comes from data reported to the Ohio Department of Health each year by every school in the state, and obtained by the Dayton Daily News. The data is only collected at kindergarten, seventh grade, twelfth grade and when new students enter other grades. Many schools have struggled to get vaccination rates up to recommended standards that health officials say would prevent outbreaks of whooping cough, mumps and measles. Some schools see parents in their communities opting out of vaccinations, but the vast majority of the schools that didn’t meet state standards missed the mark because students simply didn’t have the shots in time for the October deadline. Three out of four elementary schools in Ohio failed to have every incoming kindergartner documented as either vaccinated or exempt from vaccination by the state deadline in 2016. More on Bellbrook High School’s numbers: 26 out of 28 new pupils entering during the 2016-17 school year had all required vaccines. Zero new pupils had medical exemptions and zero had religious or personal belief exemptions.
