| Comment | Obviously global covid zero would be lovely but that horse bolted a long time ago.
Local covid zero isn't desirable because there's no end point. So long as covid is circulating somewhere in the world you're always going to need tight border controls and have the hammer of social restrictions hanging over your people in case of outbreaks because you've decided noone can become infected with covid ever.
Herd immunity is a state where there's enough immunity in a population that individual infections don't snowball into mass outbreaks because chains of infection are broken by immune individuals.

In our end state of vaccine induced herd immunity people will occasionally get covid like any other endemic virus, some will get sick and die, but there'll be no more mass outbreaks. In a covid zero approach this position would be intolerable because covid is still circulating even though it's not impacting society at large. |
