Note that that is "burn" in the sense of giving people enough immunity to prevent future hospitalization spikes. We likely can't achieve herd immunity for a disease this naturally infectious, factoring ability to mutate.
(R0 for Delta is 5 to 8 -- and our vaccine is only 64% protective against infections making the 80% herd immunity threshold impossible to reach).
- crooked-v 5y agoThe current vaccine is only 64% effective, but new safe and effective mRNA vaccines can be made on a very short timescale compared to other vaccines (as seen by the initial COVID-19 vaccines themselves). The problem isn't having a vaccine available that's protective enough... it's getting enough holdouts to actually take it before another mutated variant takes over.
