When Texas officials first discovered measles cases this year, they were among the Mennonite population. Now, officials say cases are spreading to other communities.

The measles vaccine uses a weakened virus that's never been shown to spread to others. Samples from the outbreak in Texas also show that a wild-type virus is responsible. Yet, social media posts have falsely claimed that the outbreak is due to a vaccine strain.

This week, the Texas Department of State Health Services made the Department of Government Efficiency's list of targets. DOGE plans to cut $877 million of a $1.5 billion federal grant and $97 million of a $473 million grant both from the U.S. Department of Health and Human Services.
