“Nearly 40% of new COVID patients were vaccinated - compared to just 1% who had been infected previously.””
About 10% of Israelis were previously infected. About 90% of adults were vaccinated.
That disparity alone could (should) account for some significant number more cases among the vaccinated, if protection was equal. There are other confounding factors that might come into play, with small samples.
I’d expect natural immunity to be stronger, especially among those who had severe infections - but it does not follow that vaccine protection is weak. I think that would be the erroneous conclusion some would seek to paint.
Although they use the term “patients”, in the USA we would call them “Cases” - meaning positive tests, not hospitalizations, which is what “Patient” implies in the American context.
Vaccine protection from any infection is quite good - vaccine protection from Hospitalization and Death is profoundly powerful.
Re-reading the article I see what I missed last night.
The “previously infected” group includes those who were also vaccinated. That could be all of them, or practically so.
Real world evidence of the great protection provided by natural immunity and a shot- which has been consistently shown by in-vitro testing.
