When Biden got elected, the political right/fox started a campaign to politicize Covid and the vaccines--fact. There have been efforts to portray the vaccines as unsafe when the FACT is they are safe. Does that mean that there /won't be any adverse reactions? No, of course not. But more than two-thirds of the country has been vaxxed and there have been no significant issues.
The CDC is independent and almost entirely government funded save for a little private foundation money. The FDA is a different story. It gets about 40 percent of its funding from drug company "user fees," and there has long been too much of a relationship between the drug companies and the regulatory agency. There are certainly instances of the industry having too much sway over the FDA, and no question the opioid crisis was a major regulatory failure that got a LOT of people killed, partly because there are in fact a lot of corrupt doctors in American who prescribe drugs too often and too easily. One big problem is that there is far too much direct to consumer advertising by drug companies, who go over the heads of the medical community and try to gin up demand for their drugs with TV commercials and other advertising. I think drug advertising should be banned. Even though it can sometimes cave in to drug industry pressure, the FDA nevertheless seems to do a solid job of analyzing the efficacy and safety of new drugs--powerful pain killers being the unfortunate exception. I can certainly be skeptical of big business/big pharm---but when it comes a global/national health crisis, as we had with Covid, my feeling is that there is a genuine effort by everyone to do the right thing for the public. That doesn't mean mistakes weren't made or that there wasn't confusion or uncertainty about particular issues, but this was the first major pandemic the U.S. has experienced in decades. Everyone did the best they could.
