From what I know, the vaccine doesn't lessen probability of spread just the severity of the virus.
Would it matter to you to know if you were incorrect?
I'm pretty sure that your position would be the same even if the vaccine were 100% effective in preventing acquisition of the virus. Pfizer and Moderna both reported about a 95% reduction in cases in vaccinated people, meaning that unvaccinated people were 19 times more likely to acquire the virus. Also, before delta, they were also much less likely to transmit the virus, since they carried a much reduced viral load.
That's changed with delta. Pzifer reported that its vaccine was still 91% effective against that variant, meaning that the unvaccinated were only about ten times likelier to acquire the virus in any given setting. If 1000 vaccinated and 1000 unvaccinated people were exposed to the virus such that 200 of the unvaccinated became seropositive (20%), with 95% protection, only 10 of the 1000 vaccinated would become positive, and with 91% protection, about 20 of the vaccinated would convert.
However, we are told that the vaccinated with delta COVID are now just as likely to infect others as are the unvaccinated with active disease. So although there are fewer infected vaccinated people to spread the disease, those few are no longer also less contagious than the unvaccinated with COVID.
But I don't think that matters to you. I don't think any fact or evidence can make you change your mind, except possibly the horror of watching a COVID death in a loved one, and possibly not even that. That one seems to convert a few of the staunchest holdouts, especially the ones dying, although for them, it is too late. Only the survivors witnessing the suffering and the pleas of the dying to not do what he did have a chance of benefiting from evidence.
There's also a chance that things will become so much more difficult for the unvaccinated that they will relent and get the vaccine just to keep their jobs, or to be able to participate more fully in social life. They may get tired of being unable to fly, to go to all restaurants, to see ballgames and concerts.
But short of those two, I don't see any fact being relevant to people still willfully unvaccinated.
My take away is that you are trying to convince yourself your bias is justified.
Agreed. Herself, others, or both.
I have suggested that what she is trying to do is justify ignoring expert advice that she doesn't like by disqualifying any opinion that recommends vaccination.
She did it in two parts. First, she disqualified everybody recommending a vaccine that hasn't examined her by claiming that only her own doctor has the necessary knowledge about her to decide what's best for her.
Then, she doesn't ask her doctor, the one who she says would just "look at [her] funny anyway," which suggests that she already knows what his recommendation would be, and isn't interested in hearing that, either.
