… efficacy is a vaccine’s ability to prevent development of disease, which in this case is Covid-19, and not its ability to eliminate detectable infection, in this case of the virus designated SARS-CoV-2.
According to that globally-accepted definition, we can indeed discuss Oxford/Astra, Pfizer, Moderna and the rest in terms of their ability to prevent people getting sick, and by that measure the statistics you quoted are the ones that apply. |
We are indeed talking about two different things. However the post I replied to clearly referred to a ceiling of people to infect. A number of vaccines have been shown to have near zero efficacy against Omicron infection.
Vaccines will likely change the numbers getting seriously ill and/or die. But they aren’t likely to dent the Omicron spread.
I’m not sure they’re “my own terms” when they’re the headlines all the major vaccine manufacturers were happy to run with in their own press releases.
