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.
I don't remember hearing if he got any vaccine. It would not have made sense to since he had already had covid and recovered, and thus was immune based on basic pre-2020 biology. (You know, the same biology that has 2 sexes based on very bigoted chromosomes)
Regeneron is a treatment based on monoclonal antibodies harvested from plasma of recovered people, and seems fairly safe but it's a treatment post infection not a vaccine.
Remdesivir is an expensive antiviral that doesn't seem to work but for some mysterious reason is the only one approved for use.
The approved treatment protocol is beyond fucking stupid
Here’s the video from an interview with Hannity where he admits receiving it (JnJ I believe), time stamp 3:30: https://nypost.com/2021/04/19/trumps-urges-americans-to-get-vaccines-takes-shot-at-jj-pause/
That's too bad. This may be an area where he could get better advice.
