Vaccine efficacy - % reduction in disease incidence in a vaccinated group compared to
an unvaccinated group under optimal conditions
I think we're saying the same thing big daddy.
Efficacy is just as you described but now with millions in the sample size, and just beginning the alloted time since the second dose, they'll get on to how it is projected to stabilize disease resistance over time in the population. Which I think is what we both are indicating.
I am curious as to the duration of efficacy across the various vax's and varient strains of this virus, J&J's single shot vax is almost out, different science.
One the rules I live by:
"First contact reports are almost always wrong"
