RFK Jr.'s will admit that his kids are vaccinated, even though he has expressed skepticism about many of the vaccines children receive.

The U.S. has seen three measles outbreaks since the start of the year, including one in the South Plains region of Texas. Some 223 cases have been reported since late January, the Texas Department of State Health Services said Tuesday, including one fatality in a school-age girl who wasn’t vaccinated.

RFK Jr. has claimed measles can be treated with vitamin A and that severe infection is linked to poor diet. But many experts who spoke with ABC News disagreed.
