Vaccine exemptions hitting a record 4.2% of kindergartners is a public health disaster unfolding in slow motion. Measles is at a 35-year high, and dropping MMR coverage below the 95% threshold needed for herd immunity is reckless. The Trump administration's executive order pushing states to expand religious exemptions and split the MMR into three separate shots defies scientific consensus and undermines childhood immunization. Preventable disease surges are the direct consequence of politicizing a vaccine schedule that took decades of science to build.
