I mean it's definitely good that it caused less severe variants to take over, but I remember being told by the CDC director, Fauci and President of the U.S. that I wouldn't catch or spread Covid if I took the shots.
Bunch of talking heads on tv said it too, "will stop the spread" but I don't really care about them as much, they say what they get paid to say.
They thought that... things progress though. It was very effective against the original virus, which it was made for. No one can possibly anticipate how a virus is going to mutate. Unfortunately it mutated so that it was not very effective at all against preventing sickness (though it still worked pretty well against severe disease but not anywhere near well enough all in all). It doesn't mean they were lying, it means viral evolution happened. If it hadn't evolved and had stayed the alpha variant, the picture would be extremely different.
If you look at the numbers against the original virus, they're looking really good. Not the most effective vaccine of all time, but not the least, either. In an acceptable range (no vaccine is perfect).
At this point I consider it a win because the virus is getting less deadly, and IMO we should be thinking about this as the new endemic disease similar to influenza. That is, take precautions if you're susceptible when there is an outbreak. There will be a yearly vaccine, like the flu, but some people will do it, some won't. It should not be mandated, and we shouldn't be running around like the sky is falling. Thankfully, it's less dangerous than when it first started. We're not gonna eliminate it, it's past time to learn to live with it, like we do with other endemic diseases. Everyone will get covid eventually unless you're a hermit. I've had it twice.
At this point, any further lockdowns are more destructive than the virus. Lockdown for as long as it happened probably was more destructive than the virus overall (though if you lost someone or got long covid, you might not think so - in fact I lost 2 family members, but I hadn't seen them in 15 years and we were estranged so it didn't affect my life, as sad as that is to say). The original caution was the only sensible thing to do though... we knew almost nothing about it, and people were dying. I think lockdowns went on too long, and at this point trying to enforce vaccine mandates still is nonsensical, since it doesn't stop you from getting and catching it, only reduces its severity... an argument could be made that less people in the ER costs society less, but I don't think that trumps personal right to choose what to put in your body, when at this point all it's doing is protecting you, if you want to choose not to get that protection, that's your thing. I won't be getting another booster, I got boosted and caught omicron anyway and I'd rather just get omicron again, unless there is another mutation where I am seeing it become far more dangerous again, and a vaccine can be proven to me to greatly reduce the risk. Then I'd consider it. But as it stands now, I'm done with it, personally.
