They reduce the likelihood of catching it, and reduce the likelihood of transmission when you get it.
A herd immunity situation still involves individuals catching and spreading a disease, but the R value is below 1, so it fizzles out quickly.
Have a node in the graph reduce both incoming and outgoing probability of transmission reducea the R value.
The argument you can make is that covid's R value is so high that it doesn't matter how many people get vaccinated or catch covid, it will continue spreading, but "full protection" is irrelevant
- mythrwy 5y agoThe "reduce likelihoods" would need real numbers to determine if the R value would be below 1 and thus fizzle. Hand waving doesn't show this and I feel it's unlikely given the amount vaccinated infection observed. We didn't know everything we do now, but near as I can tell herd immunity was never a realistic possibility. It was with for the foreseeable future as soon as it went multinational and became a management rather then elimination task.
