Not a fair analogy (in my opinion) because, as delicious as M&M's are, they are not something that can protect the vast majority if you personally eat just one. (and who can eat just one??). I see your point, but the idea of the vaccine is to get as many protected as possible, to then protect others. It's supposed to be perpetual. And the gains are supposed to outweigh the risks. From what I've read/seen/heard, they still do. (the AZ jab notwithstanding)ie; Here's a bowl full of 100,000 M&M's, knowing that one or more of them may be poisoned. Would you still risk it and help yourself to them?
I am (relatively) healthy... and could most likely survive from COVID, but my dad couldn't. My mother in-law couldn't. I did it more for them than myself.
I was not first in line though. I waited to see if there was a Zombie Apocalypse.
I did not grow a third nipple.
The tail is pretty handy though!
