US childhood vaccination exemptions reach their highest level ever

The proportion of U.S. kindergartners exempted from school vaccination requirements has hit its highest level ever, 3%, U.S. health officials said Thursday.

More parents are questioning routine childhood vaccinations that they used to automatically accept, an effect of the political schism that emerged during the pandemic around COVID-19 vaccines, experts say.

Even though more kids were given exemptions, the national vaccination rate held steady: 93% of kindergarteners got their required shots for the 2022-2023 school year, the same as the year before, the Centers for Disease Control and Prevention said in a report Thursday. The rate was 95% in the years before the COVID-19 pandemic.

“The bad news is that it’s gone down since the pandemic and still hasn’t rebounded,” said Dr. Sean O’Leary, a University of Colorado pediatric infectious diseases specialist. “The good news is that the vast majority of parents are still vaccinating their kids according to the recommended schedule.”
