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.
Yes I think at this point switching policy to ivermectin treatments and no boosters is a reasonably effective way out. As long as ADE is not a common problem, vaxxed people are probably a little worse off than unvaxed after 6 months, but with early treatment with an antiviral hopefully not that much worse off.
Even if ADE is a problem post vax, so far it seems like it only effects certain immune systems, not all people. Here's to hoping because otherwise there's really no solution to that problem
