A small but growing measles outbreak in central Ohio has sickened at least 77 children, almost all under age 5. The vast majority are either unvaccinated or have received just one of the two recommended doses of measles, mumps and rubella vaccine, according to City of Columbus Public Health.
More than a third of the children have been hospitalized.
The outbreak, the largest in the U.S. since 2019, is happening as resistance to school vaccination requirements is spreading across the country.
On Friday, the Kaiser Family Foundation released data showing that 28% of adults surveyed this summer were against vaccination requirements for kids entering kindergarten, up from 16% in 2019.
The percentage of parents who said they were against vaccination requirements for school was even higher. This year, 35% of surveyed parents said it should be up to moms and dads whether to have their kids vaccinated, up from 23% in 2019.
