I will continue to disagree with your one size fits all prescription. It would be trivial to allow an antibody test in lieu of vaccination.
Responding to your edit: I already answered the original question. Allow an antibody test to prove immunity. Stop demanding vax as if it's the only way to acquire immunity.
It's quite funny to me how presumptuous covid vaxx advocates are. They seem to be saying, "you're going to have to relent eventually. What do I need to say to speed that up?". As if there aren't people who will listen to what they have to say yet continue to refuse and have perfectly valid reasons to do so.
That's not an answer to the original question. That's an excuse to not take the vaccine, and I've already addressed how these two things aren't the same.
If 999/1000 of vaccinated people were uninfected while only 998/1000 unvaccinated (but recovered) people were uninfected that would amount to that 2x improvement.
When you look at the error bars on those numbers (due to the ridiculously low statistics of the study) the conclusion becomes even more suspect.
Frankly a study involving less than a thousand participants is pretty poor justification to strip others of their rights.
I do believe the carrot works better than the stick, but I don't think this goes as far as being "treated like a threat".
I understand that you believe that unvaxxed are where the mutations happen.
I didn't say this and this is not my full belief :( . Mutations can happen at any new infection (including breakthrough infections, yes). So, the premise is to reduce new infections as much and as fast as possible. I think we're on the same page that vaccination greatly reduces your chance of infection (even more than having previously been infected before). Getting the most people vaccinated, as fast as possible, is the most efficient way to achieve that.
Overall, though, you've gotten pretty far away from the original question, "Well, what would it take for you to change your mind [to get the vaccine]?"
