U.S. kindergarten vaccination rates dipped last year and the proportion of children with exemptions rose to an all-time high, according to federal data posted Tuesday.
The share of kids exempted from vaccine requirements rose to 3.3 percent, up from 3 percent the year before. Meanwhile, 92.7 percent of kindergartners got their required shots, which is a little lower than the previous two years. Before the COVID-19 pandemic the vaccination rate was 95 percent, the coverage level that makes it unlikely that a single infection will spark a disease cluster or outbreak.
The changes may seem slight but are significant, translating to about 80,000 kids not getting vaccinated, health officials say.
