That study seems very odd to me. Patients in most cases were given some combination of vaccines Pfizer/Moderna being the most common combo. That's not how it's done in real life (at least not normally). Also, one of your links mentioned that the Moderna vaccine led to 3 times the rate of heart problems than the Pfizer vaccine. Mixing all the stats together as if there was one vaccine gives somewhat of a false impression. But knowing that certainly makes the Pfizer vaccine seem a lot safer.

I get the impression that gateway pundit article is very misleading as well. It talks about myocarditis increasing you risk of death by a lot within 5 years, however my understanding is that would be for a chronic condition. While the mRNA vaccines may have myocarditis as a possible side effect, it is an immune response and is usually temporary and self limiting. That isn't to say it can't be dangerous, it certainly can. But not in the long term way that article indicates. Most myocarditis cases triggered by the vaccine are mild and treatable or self resolving with no long term effects likely. While you might not be able to say definitively that the vaccine won't have long term effects, the likely long term effects of myocarditis specifically can be determined by severity. While there may be a 1/1000 (0.1%) chance of myocarditis, the chances of a severe case with potential long term side effects is much smaller than that.

As you indicate, Facebook will do whatever Facebook does because they do it for money. That doesn't really say anything about the veracity or accuracy of the comments though.

People want to proscribe some sinister motive for pushing the vaccines but it is really simple. Covid spreads much easier and faster than the flu, it also has symptoms that, on average, are somewhat worse than the average flu strain. Hospitals do not typically have lots of extra capacity in the best of times. It wouldn't be too difficult, if COVID were just left to run rampant, for hospitals to be overwhelmed. If this happens, even more people will die. The vaccine is supposed to slow the spread, reduce your chance for hospitalization and reduce your chance of death. It SEEMS to be doing that. As far as risk factors, well, if you are a young adult male, consider the J&J vaccine over Pfizer or Moderna. If you are a female of child bearing age consider Pfizer or Moderna over J&J. If you are not in one of those groups, flip a coin. The point is, the risks are pretty well known and publicized. You even have to sign something that says you have read what they are before getting the vaccine. It's easy to make a choice that limits your exposure to risk even further.

I keep hearing conflicting stories about how in some places, most hospitalized people are vaccinated and in others they are not. I'm not sure of the reason for that. I can say that here in Florida, most hospitalized people have been unvaccinated...by a very large margin (95+%). Most of the stories that show the opposite seem to be coming out of Israel but i'm not sure of the origin. News articles that I have read out of Israel indicate that the Pfizer vaccine is only ~40% effective against the Delta variant but still highly effective vs. hospitalization and death. I suppose that it also may be true that there is a genetic component where the vaccine works better in some groups than in others.
