Why would we need to vaccine absolutely everyone ? isn't herd immunity a thing?
- gibatronic 6y agoStill, it would be a lot of people: 50 to 83% [1], and more importantly, it has to be evenly distributed. It would be pointless to have developed countries safe while the rest of the world is in chaos. We're a global economy after all.

- kwhitefoot 6y agoNot yet, and it is possible that immunity does not last long enough for herd immunity to ever happen. It's too early to tell.
- nickthemagicman 6y agoThis is false immunity is strong and long-lasting otherwise they wouldn't be sinking billions into a vaccine which operates the same way that infectious immunity operates.
- anon98356 6y agoHerd immunity is a thing, but as I heard one scientist describe it: It's not a question of achieving herd immunity or not, it's a question of how. Mass vaccination also leads to herd immunity, it's achieved by creating immunity in individuals through a vaccine instead of by contracting the virus naturally.
