The first stage was: these anti-vaxxers don't have a degree in immunology, what makes them qualified to even attempt to interpret scientific papers on the subject?

The second stage was: wait, I don't have a degree in immunology either, why am I pretending to be "following the science" when I don't have even the vocabulary or the context to properly grasp immunology papers?

Accepting that I am a functional ignoramus with regards to Covid, viruses, immunology, vaccine development etc. is very freeing. I'm basically knowledgeable on very few things, and am not an authority on (vaccines|economics|law|history|basically everything). Being good at software engineering doesn't make me an expert at everything I read two articles on.
