Agreeing with RFK would mean that Trump has thought about and has an opinion on government’s role in healthcare. Trump got the COVID vaccine the moment it came out. Trump only cares about RFK as a chaos agent and embarrassment to the Kennedys.

He's waiting on Laura Loomer's guidance. Once she declares he's "still a Dem!", it'll be dicey for RFK ... although Trump LOVES that a Kennedy is on his side erroneously believing the man still has some Kennedy prestige. And as you said, he agrees with his "science".
