> I know you used "pretty strongly" as sarcasm, but it's not falsifiability is absolute - and this is not.
I'm having a very hard time parsing what you're saying. At this point, it looks like you're trying to make an argument that "falsifiability" must mean that it is both possible and practical to reject a hypothesis with 100% certainty, and if you can't then you're not doing science. Would you care to explain more clearly why the position you're taking is less extreme and absurd than that?
(Additionally, I did not use "pretty strongly" in any sarcastic way. I used it to acknowledge the possibility of confounding factors that I did not care to enumerate, which mean that even the experimental outcome of getting COVID-19 after inoculation with the homemade vaccine would not be a 100% certain rejection of the hypothesis that the vaccine conferred some protection against COVID-19. But if you're operating in a mindset of 100% certainty being achievable and necessary for science, then I can see how you would misunderstand me.)
