Cases in the ongoing measles outbreak have risen to 258 across Texas, New Mexico and Oklahoma, and state health departments are urging more people to get the measles-mumps-rubella vaccine. In an interview with Fox News, HHS Secretary Robert F. Kennedy Jr. said that "people ought to be able to make that choice for themselves. And what we need to do is give them the best information and encourage them to vaccinate. The vaccine does stop the spread of the disease." But Kennedy also downplayed the safety of the vaccine and wrongly told Fox News' Sean Hannity that measles outbreaks could be driven in part by people who have waning immunity from the vaccine.
