Attorney General Josh Kaul says Wisconsin is joining a lawsuit over federal changes to the childhood vaccine schedule.
Attorneys general from 14 other states, along with the governor of Pennsylvania, are also part of the effort. The suit challenges the Trump administration’s decision to remove several vaccines, including rotavirus, hepatitis A and B, and COVID-19. State health leaders report responding to measles cases in 2025 and 2026, including 36 in late 2025. Officials say all cases involved unvaccinated people.
