Reply to comment by swesley49 in A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga

Even as spelled out in your comment, the vaccines do not induce herd immunity. They merely help to reduce death while herd immunity is being developed through natural infection.

Although you cannot qualify the efficacy of a vaccine simply by its ability to reduce severity of infection from the targeted pathogen. You need to look at all cause death over the long term.

First, yes, AFAIK herd immunity may very well require true immunity. Although I'm also thinking about the possibility of reducing infections by enough that the spread is just too slow to get through our quarantine strategies. In that case, vaccines don't need to provide full immunity.

Second, these vaccines are not and will not ever cause more deaths than covid. I'm not sure what you mean by looking at all causes of death.

Do you have any data to suggest that these vaccines effectively reduce the rates of transmission? If so, by what rate?

Secondly, are you suggesting that zero people who would fully recovered covid without vaccination, will suffer a death caused by an adverse event caused by these vaccines?

Do you know how many healthy people you need to vaccinate in order to statistically prevent a single covid death?
