So far, I personally have encountered the following viewpoints in my family and peer group (none of which I share) - in decreasing order of how much credence I'll give them:
1. I'm pregnant and don't know what it does to my baby.
2. I do not think the vaccine is safe, because we developed it too fast. Corollary: blood clots in two of them are my proof.
3. I agree the vaccine is safe and effective, but it was made with "aborted babies" [actually: stem cell lines, as are many vaccines that I'm sure they _have_ taken], and I will not take it on religious grounds.
4. I will not take the vaccine on principle, as it constitutes government overreach into our lives. It is irrelevant whether it is safe or effective.
That's not to speak of some of the other egregious ones I've heard that people believe, like the vaccine having an ICE tracker embedded in it to enable roundups (https://www.boston25news.com/news/health/local-leaders-vacci...).
Given that all of the communication I've seen has centered around safety and effectiveness, it seems like two out of these four cases are not being addressed.
