What do you mean by not working? It seems that the two choices are a.) getting covid and building some immunity or b.) getting a covid vaccine and getting some immunity, in the end a and b both provide some immunity. To me the downsides of a are clear, but I'd be interested in hearing why you think there are no upsides to b.
> remember the lab leak hypothesis?
I'm not expert but I think the most recent thing I heard about the origins of COVID is that is some natural origin is back on the table as the most likely scenario.
> definition of vaccine was modified to fit that new drug
Please tell me if I'm mistaking what you mean, but I don't think the definition of a vaccine was modified? Instead I think the public had a working lay definition, based on the success of previous vaccination efforts. I think the definition was always something like a medicine that enhances immunity against a disease.
> The whole thing is sickening.
This I agree with, but for me it's been more that people start with conclusions, work backwards to find evidence, and then call it research.
