There is sometimes a minor theme on conservative sites about being suspicious of vaccines in general or swearing by some form of alt-medicine. I seem to recall that this is worse on conservative sites I don't go to very much - only when linked by a site I have more trust in, usually. The idea of things that are "natural" being more what the Bible teaches and God wants has traction in Christian churches.*
This has exploded on conservative sites over the covid vaccine. People are making their medical decisions on political grounds of "not trusting the government," or to be fair, of trusting the government not because it is trustworthy but because it is what their party currently requires of them. Pfizer and Moderna are not the government. If they are hiding something just to make a quick buck and it turns out to make you sterile later, the class-action suit would bankrupt them. They might be many terrible things, but stupid is not generally one of them.
You can also put in some effort and look at the numbers of what the testing of vaccines has produced in terms of side effects. Or you could, of course, just let highly partisan and politicised people tell you what's safe and what's not. Because they must know more than "so-called experts" because they share your suspicion of "experts," right? What other evidence do you need? They are suspicious of experts, you are suspicious of experts, they like to show how independent and brave they are by "standing up" to the government, and they must be right!
Between liberals and conservatives on this issue, it's really hard to decide who has been the smart kid in the dumb row.
The latest twist is a flurry of stories about how nurses and other health professionals (drive a truck through that) are declining to get the vaccine at an "alarming" rate. There is a study out of Europe making the rounds that is supposed to provide evidence that YOU should be suspicious because all these European Health Professionals must know something you don't.
I think I can be of some help here. I spent forty years working with nurses and "other health professionals," including the occasional European. Nurses believe a lot of woo. Not all of them certainly, but a ridiculous percentage. They often went into the field because they had strong priors about What Other People Need To Do. For "other health professionals," the OT's, the massage therapists, the chiropractors, physical therapists, registered dieticians...double that. Also for Europeans, double that. That still leaves plenty of entirely reasonable people in those fields, but please, don't take the fact that you can find "alarming percentages" of these folks supporting or opposing anything as evidence. They love Reiki. They love herbs and homeopathy - the modern definition, not the previous theory of "the water remembers" - mind-body medicine, integrated medicine, suspicion of GMO foods, megadoses of just about anything that comes in a bottle.
Hell, even some doctors believe that stuff. No amount of data and training will beat it out of some people. I applaud people who try to be open-minded, willing to consider whether St. John's Wort, or Rolfing, or bee venom really do work. I admire their fortitude in the face of other professionals scoffing and telling them they are silly. But I neither applaud nor admire people who still hold these ideas after the evidence is in, especially if the proposed treatment is not merely ineffectual, but actively damaging.
Pay zero attention to news stories about what European Health Professionals think about the vaccine. They know more random facts about medicine than you do, but you start from a much firmer foundation of "Look, all I want to know is if this is a good idea or not, and I am willing to do some reading." They have agendas, you have a family.
