More data from Israel’s vaccination program suggests the Pfizer jab prevents 94% of symptomatic infections.
The Pfizer Covid-19 vaccine is proving highly effective at preventing illness and severe disease among all age groups afflicted by the coronavirus, according to public health doctor Prof Hagai Levine.
Israel’s largest health fund Clalit looked at positive tests in 600,000 vaccinated people and the same number of unvaccinated people, according to age and health status.
It found 94% fewer infections among the vaccinated group.
This pattern was the same in all age groups—including over-70s, who may have been under-represented in clinical trials.
The vaccine prevented almost all cases of serious illness.
The data from the trial has not yet been formally published.
