My favorite is the play to authority "my cousin works in healthcare" the logic being their relative who is some low level tech that cleans bed pans should be listened to instead of the tens of thousands of actual doctors and scientists saying the opposite.
If only. They'd sooner take medical advice from a garbage man than a leading professional in virology and vaccinology. This is what happens to your brain when you're in the grips of unrelenting fear 24/7. This is why they created every nightmare scenario you could think of relating to the vaccine before, during and after it's release. It's literally nightmare and nightmare. This is what is constantly revolving through their heads every day. They're an emotional mess.
