In her hometown of Lubbock, Texas, Leah, a pregnant mother, has been avoiding stores and other public spaces for the last two weeks. On Wednesday, the city saw a six-year-old child who was not vaccinated against the virus die – the first US death from the measles in nearly a decade.

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.

Dozens of children have contracted measles in Texas' largest outbreak in 33 years. Online, some are blaming vaccines for the disease’s spread.
