On February 20, 2024, amid a measles outbreak at Manatee Bay Elementary School in Broward County, Florida, Surgeon General Joseph Ladapo sent a letter to parents stating that the Department of Health was 'deferring to parents or guardians to make decisions about school attendance' for unvaccinated children. The letter acknowledged that measles is highly contagious and that the MMR vaccine is effective, but it did not urge parents to vaccinate. The guidance contradicted CDC advice that unvaccinated children exposed to measles should stay home for about three weeks, and drew criticism from public-health experts.
