"The order recommends that all shots be given at separate medical visits, a frequent point Trump has made despite the safety, ease and lower costs of giving vaccines together."

'“Together, there could be a possibility they’re quite lethal,” Trump said of the MMR vaccine at the signing of the order on Monday.'

'Asked if he had evidence that the combined MMR vaccine was “lethal”, Trump said: “No. What I’ve heard is that there are some people who say it is that way.”'

Antivax fundamentally has its contemporary roots in Andrew Wakefield's fraudulent anti-MMR campaign.

So directing by executive order and by his own admission without evidence that the MMR vaccine be split up into separate shots is, very clearly, an antivax action. This is the first victory that Wakefield (a man who had a patent on a single measles vaccine!) wanted, and RFK Jr was pursuing.

But this is Trump saying this and signing it. So as of yesterday, it now has everything to do with Trump, sorry. He has handed the anti-MMR movement its ultimate victory and in so doing validated the entire antivax worldview.
