I'm sure there are usecases for it. It probably should have been studied longer and not rushed out and promoted for profit with false advertising peddled by all the mainstream news organizations.

The thing is it is still effective at reducing symptoms and deaths from COVID. My mom is immunosuppressed and she would have probably died from COVID without the boost to her immune system when she did eventually catch it.
I can see why people are upset though about the risks not being disclosed well and some people having to choose between their job and getting the shot. I just don't think it's a hill worth dying on. The messaging is really tough too, because if you come out against the COVID vaccine people might think you're also against traditional vaccines which have completely irradicated some really nasty diseases.
Idk, I think an experimental vaccine was an appropriate response to the COVID threat at the time. Same with lockdowns and mask mandates. We didn't understand it well and couldn't have known it would evolve to be so much less deadly. Hospitals were getting overwhelmed and people were really afraid.
All I could suggest here is that if this topic interests you, you should dig deeper into it.
The rabbit hole is deeper than what Bitcoin made you understand about money and a lot of other truths.
