This study says much less than 71% reduction, 25% of vaccinated and 38% of unvaccinated people got Covid when living with an infected person.
a) eradication to be a possibility (intuitively, it would seem not); or, failing that
b) to lower the possibility of novel mutations emerging to a negligible level (I don’t have the knowledge to answer, so this is a genuine question, but again intuition would suggest not)
if, say, 99% of the population is vaccinated.
I’m asking if that makes sense given the evidence, and commenting that my (lay) intuition says it isn’t.
