Imagine scientists could invent an effective, safe, cheap way to prevent a wide range of terrible diseases and the people in charge of the nation's health system worked hard to stop people from using them.

The share of counties where 95% or more of kindergartners were vaccinated against measles has dropped from 50% before the pandemic to 28%, according to our analysis of public records from 44 states and the District of Columbia. At least 19,000 schools are now more vulnerable to outbreaks.
