I think there's two sets (or batches) of vaccines. Trump bought up FDA untested vaccines that were in development on the gamble they would be ready before his term was up. He may have had a futures type of deal, and the final price was dependent on the speed to release and effectiveness of the released product. Then he didn't charge for it. Downside has always been the apparently quick run in, which would have the effect of ratcheting up the questions of the vaccine's safety. It may have been the only card to play at that juncture, though.
My feeling is the vaccine, coming out of HIV/AIDS research was fairly well tested and, with minor modifications, not a long term development item. That short-circuited any, for example, Fauci, plan to gaslight a 5 year or more timeframe and to jack up the public's acceptance for and the price of the product that crew was promoting.
So, Trump's vaccine was pretty much a known quantity, he went private sector to get it developed, and it may very well do what it says it will do on the tin, with downside it was, arguably, not safe because of the lack of testing.
Say, however, that whatever is circulating know has the Brandon gangs paws all over it, either content-wise or monetarily, and is used as a crony type money making scheme in cahoots with big pharma and Fauci's agencies.
Perhaps, for example, all the vaccine requirements many countries WW are imposing are because foreign aid or military aid now have "strings attached" in conjunction with vaccine sales. Basically, say, vaccines sales are subsidized for these countries via US tax payers in the form of foreign aid.
That scam, if it, or something like it, does exist, is a post-Trump introduction by Brandon's boys, though. If the boys are now getting 'skeered, that it may be revealed, then my guess is they are going to try to drag Trump into it by conflating their scam products with the original Trump rollout.
Trump has been saying, though, that he is proud of 'his' three vaccines, and that they're good, they work, but with the caveat that nothing medical should be mandated. So, I see it as a move by Trump to get daylight between his original initiative, and whatever bastardization the Brandon gang may have undertaken to get their big guy 10% out of the uninterrupted pandemic politics.
If Trump's stuff actually worked, and maybe they do, there should be no further need for pandemic politics. That's where the circle back bites itself in the ass. If Brandon's boys tell Psaki to say the Trump stuff sucks, then why mandate it? She's saying the Trump stuff is good, though, which isn't evident in the continuing spread of variants needed to keep the pandemic going. That, if my take is accurate, is because of the shit Brandon's gang is offering up, though. Psaki can't say that.
Recent history tells me the card these fuckers pull when their backs are against the wall is to blame Trump, and I think this is just an attempt to try to do just that before the revelation of the bullshit that was pulled by the Brandon gang gets revealed.
