"Herd immunity only applies if the vaccine ... prevents infection".
There is no vaccine that prevents some kind of infection with 100% accuracy across all population.
Basically implies you know jack about herd immunity.
- collias 5y agoYou're right, no vaccine is 100% effective. But there are vaccines that are more than ~75% effective at preventing infection, which is the number that Fauci kept mentioning when this all started.
- esalman 5y agoHerd immunity does not depend on the efficacy of the vaccine. It depends on the R_nought of the disease. There are several ways to reduce the R_nought below 1 (at which point we achieve herd immunity). Vaccines is just one of them. Claiming things that vaccines don't work, doesn't prevent infection, impossible to achieve herd immunity with them- helps absolutely nobody.
- collias 5y agoCovid-19 vaccines don't prevent infection, and it is impossible to achieve herd immunity with them. These are facts, and they are relevant to the comment I was originally replying on.
- esalman 5y agoWhere did you find these facts? fyi, I have studied epidemiology in the context of network science in school.
