Vaccine Efficacy Rates not correct?

They were almost certainly overstated. My understanding is that in the trials they tested relatively few old people. Skewing the trials to younger, healthier people drove the efficacy % higher. I still think they will be good and effective. Just probably short of the 95% advertised. That may be what is playing out in Israel.
