It sure does. I know you have debilitating autism to the point where you get a tugboat for it and thus your diseased brain cannot understand things that aren't 0% or 100%, but they are still effective even though they aren't 100% effective. Why do you anti-vax retards keep parroting this incorrect talking point? Is it because, like your cult leader, you want to repeat a lie over and over again until it becomes true?
It does this, too, but again, not 100% effective.
Maybe. The jury is still out on that.
Citation needed on 80% being immune to covid. You can still catch covid, even severely, if you've already had it, you retard.
Again, why do you want the vaccine to fail? You haven't answered that yet, son. I know you won't answer these questions and you'll dodge them like a good little anti-vax spaz, but at least I gave you a chance
