It sounds like Trump is now beginning to publicly cast some doubt on the vaccines. He's starting cautiously, by questioning the booster shots, but I suspect (hope) that he will be slowly ramping up the questioning and criticism going forward, from here on out.
If he knew what "vaccines" really are, he would never have recommended anyone get jabbed.
I remember hearing Trump on... was it the Hugh Hewitt show? Loooong time ago. I think it was before 2016. Anyway, he was going on about vaccines. He wasn't even against vaccines, he just said he thought they should be spaced out from each other. He said he saw a huge syringe that looked like it was going into a horse, but injected into a little baby, and the syringe looked like it could hold about half of the blood that baby had.
