But @donquixotedelamancha, the vaccines cannot lead to herd immunity. This has been stated now even by the most mainstream, vaccine-enthusiastic of scientists and politicians. We were told at one stage that they would (when we were told - mistakenly - that they would prevent most cases), but it simply can't be the case when people who've had the jab readily get and pass on the virus
Yes and no. Nobody who understood the science thought there was much chance of getting sterilising, long term immunity at any point in the pandemic. I said that on here from early on.
You can get a kind of herd immunity by having enough of the population vaccinated to get the R number below one.
This would involve a very high uptake (possibly still some public health measures over winter) and vaccine boosters ever 6 months or so but it's possibly doable and it's still the goal in some regions.
Some variation on this, to reduce the spread and impact, is the only reason I can think to pay people to vaccinate.
You are right that this is not strictly herd immunity in the usual sense, I was being imprecise.
