Measles has sickened nearly 150 mostly unvaccinated people in rural West Texas, and a school-age child has died. The virus is spreading among Gaines County’s Mennonite community, where government mandates are not trusted.

When the local hospital warned of a brewing measles outbreak, Kaleigh Brantner urged fellow residents of this rural West Texas community to beware of vaccinating their children. Two weeks later, her unvaccinated 7-year-old son came home from school with a fever.
