you truly are foolish. everything is a risk in life. i had no good reason to disbelieve the CDC (they are generally well trained and well informed; i know because i trained some of them), and after almost dying from my first case of Covid, and knowing the basic biochemistry of how RNA vaccines work, it was a no-brainer to take the vaccine when it finally came out. the people who thought we were gullible and refused the vaccine, well, a lot of them died of Covid. serious side effects have been rare, so the intelligent decision was to risk the vaccine. i got my most recent booster yesterday and have been Covid-free since Spring 2020 with no significant side effects.
