the reality is that there's probably something like a 95% chance that the vaccine out of russia is fine. for me, a 5% chance of complications is many orders of magnitude higher than the likelihood that the virus harms me in any way. so, i'll wait.
but, if i was a little older, or diabetic, i'd jump at it.
technically, it's untested and comes with some risk, but this isn't as reckless as it's being portrayed as, and things will probably work out fine.
