The modal vaccine 'skeptic' with respect to covid mostly complies with things while people are watching and is worried about something in their life forcing them to take the vaccine and putting off the choice as long as they can.
Some are combing through VAERS data, reading stuff from scientists about how this stuff works, etc. so I think what we really know is more accessible stuff to relay what we do and do not know as factually as possible without trying to directly convince anyone, instead making an honest best effort to put the 'informed' into 'informed consent'.
Yeah, there will always be a few who don't go for it, but if you want to help the most people who are nervous, that's the best approach to take as someone who has managed to convince a few nervous people to get vaccinated.
I'm doing my best to help people in that vein, but I'm only one person.
