As for me:
I used to trip off street drugs when I was a teenager, no idea what I was actually taking, only the word of the dealer for it and what I felt.
After remembering what I used to do out of boredom I feel fine and safe taking a vaccine, from a doctor in a hospital, that was tested and peer reviewed, even if some people question if it was enough test.
Ah yes, to be young and wild again. putting all sorts of crazy drugs in our bodies.. hahahahah. Good times but I wouldn't go back to that, best left in the past!
I mean, is the vaccine safer than street drugs? Man I fucking hope so, but we really don't know for sure yet. Maybe I am paranoid, but I don't exactly take what the government or health / pharma industry says at face value anymore. :(
