I don't know about you but personally I have not met - nor heard of - many people who reject all vaccines and see no value in vaccination. As for these COVID "vaccines", so called (they wouldn't even qualify as vaccines under the old definition) - well, being wary of them is just common sense. This is experimental technology, developed by parties that have a questionable reputation, using a process that they don't want to be transparent about, with more and more evidence coming out that shows that bad side effects are not so infrequent. It sounds like common sense to me to be suspicious of a technology like that.
