The Delta variant is so contagious that everyone will eventually be exposed regardless of what we do. There will be no significant herd immunity effect to protect people who cannot be vaccinated or who are immune compromised.
Vaccinated people who get infected are probably contagious for a shorter period. However that only marginally reduces the risk of contagion for any individual interaction. Over an extended period of time everyone will be exposed.
Think of it like a soccer goalie defending against an endless series of penalty kicks. He might block the first few but eventually a ball will get through.
Yes: if you notice I used the word less, that’s why. Anything which reduces load or time cuts into the R factor — we still need masks to get the community levels under control but it seems likely that vaccination will let us hit the point where immune compromised people, those with allergic reactions, etc. can live normally during non-pandemic conditions.
