People have their own circumstances, and some may be medically advised against the vaccine for such circumstances.
But when I saw that the Moderna vaccine was not only 95% better than control - meaning that your chance of getting Covid is approximately 0.1% - and that even if you did get it, you didn’t need hospitalization - I was on board. What I got was Pfizer, but it’s quite similar to Moderna, so I reckon the probabilities are about the same.
I accede reluctantly to the mask requirements in effect out of courtesy, but otherwise have no confidence that my wearing them significantly benefits anyone. The requirements are a nuisance.
