President Donald Trump compared the Measles, Mumps, and Rubella vaccine to a nuclear bomb being set off inside a kid's body during a Tuesday interview on Real America's Voice. The president championed the new childhood vaccine guidelines he and HHS Secretary Robert F. Kennedy Jr. debuted Monday, with Trump claiming the old schedule was "too big" and "too much" at one time. He then talked about the MMR vaccine . "If you give them separately " the M, the M, and the R, it's fine," Trump said. "When you put them together, they're sort of like a nuclear weapon, according to some. So why wouldn't you give them separately? What's hurt by giving them separately?"
