U.S. Health and Human Services Secretary Robert F. Kennedy Jr. said he’s spoken directly with Gov. Greg Abbott about the measles outbreak in Texas, but neither are telling Texas families to get the vaccine that can stop the spread of the highly contagious respiratory illness.

Kennedy wrote in an opinion piece published Sunday on Fox News Digital that parents should consult with physicians about the MMR vaccine.

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.
