With the caveats that 1) I suspect that this isn't actually data-driven as RFK Jr. is an anti-vax nut and 2) personally I think the government should fund vaccine development:

Were Shockley, Franklin, or Watts funded by the US government? To the tune of half a billion dollars?

That's not a rhetorical question - I don't know to what extent their work received grants. But I think you need to connect those particular dots to effectively make the kind of comparison you're making.

The implication of your post (sort of) is that work on mRNA vaccination development either needs to be funded by the government or it'll be given up on. If it's the kind of breakthrough that it likely is (and already has been, really) I doubt that's really the case. It's just unfortunate for Americans and the world that the work will likely be done elsewhere, perhaps more slowly, and perhaps (?) with less public (rather than for-profit) interest.

it will be government funded, but just not our government, and not in our universities

AIUI early transistor research was funded by public (defense) grants. And Bell Labs was definitely government supported, if not outright government funded.
