Science is hard :p

Good poker players can lose all their chips at the table to an unlucky draw and walk away knowing that they made the right play and that they'd do it again, even if they got unlucky on the river card. Good basketball coaches will still draw up plays to get the ball into the hands of their best shooter at the end of the game even if they miss sometimes.

If you're choosing between option A that has a 0.0001% chance of hurting you and option B that has a 10% chance of hurting you, and you choose A and still get hurt, that doesn't mean you made the wrong choice or that if you have it to do over again you should choose B.

In reality, we don't have that. We get whatever ideas have the largest marketing budget behind them, and we just have to trust them. It's more like "nobody gets fired for buying IBM (or pick your favorite pundit)" than running a poker scenario through a solver. And that's fine, I don't think you can expect much more than that out of people.

The stupidity of requiring people that already have antibodies to vaccinate, or even to require people to vaccinate. If you are worried, vaccinate and that's it, you are protected, don't impose others to do it. Especially a novel experimental vaccine that changes your genetic code.

Pick your poison, then.

2. The vax doesn’t prevent infection anyway, so whatever the point they are making is moot.

3. The risk is being compounded each time- first from vax, then from infection, then from boosters.

I don't understand why anyone would do that, perhaps only because they understood that it was a mistake and they want others to make the same mistake.

You're saying "If you survive getting covid without serious injuries once, then you'll be less likely to get serious injuries on a re-infection later". The vaccine is to make it less likely that you get serious injuries from that first exposure.

The argument makes more sense when you take into account that the interesting case is actually "given that you've already had covid, should you get vaccinated?" rather than "given no exposures yet, should I make out with someone that has it or should I get vaccinated". I've seen a lot of noise about the latter case, and a lot of overlooking the former.

COVID was around before the vaccines, and before the boosters, and between the boosters. Some of us got it before the boosters were available, and before the next booster was due. This is the context you're responding to.

For a stupid real world example, my college friend had COVID was required to get the booster while he was recovering from COVID, so that he could continue school after. There's plenty of nonsense still going around. Natural infection usually doesn't count in the school system, from what I've seen. Surprisingly it does, where I work.
