Well. We kinda all need it by that logic if we are going to be around people who are over the age of 70, or anyone else who might be around someone that age, were going to want to reduce the virus per particle as much as possible. I suppose we could just quarantine everyone over the age of 70 to prevent hospitals getting overwhelmed instead.

A 95% reduction of virus proteins in your body typically equals a roughly 95% reduction of virus proteins in your airborne respiratory particles.

You're right tho, it's going to be brutal still next summer without the right combination of people getting the virus, wearing masks, social distancing, staying home as much as possible. We ALSO have to lower community spread period. No matter how we go about this we cant succeed if 20% of people have it at once like some areas.
