Confirmation bias.
Sounds like a theory that works both ways.
Anti-vaxxers and pro-vaxxers will use Confirmation bias to support their arguments and tear down their opponents.

Certainly true. But there is also this: the anti-vaxxers base much of their argument on an allegation that there really isn’t a threat from the CV that would justify taking the vaccine. They are also stressing that even though CV disproportionately affects the elderly, the elderly are even more vulnerable to the side-effects of the vaccine. IOW, no one should take the virus.
