Israeli Study Finds 94% Drop In Symptomatic COVID-19 Cases With Pfizer Vaccine
02/14/2021
Israel’s largest healthcare provider on Sunday reported a 94% drop in symptomatic COVID-19 infections among 600,000 people who received two doses of the Pfizer’s vaccine in the country’s biggest study to date.
Health maintenance organization (HMO) Clalit, which covers more than half of all Israelis, said the same group was also 92% less likely to develop severe illness from the virus.
The comparison was against a group of the same size, with matching medical histories, who had not received the vaccine.
“It shows unequivocally that Pfizer’s coronavirus vaccine is extremely effective in the real world a week after the second dose, just as it was found to be in the clinical study,” said Ran Balicer, Clalit’s chief innovation officer.
He added that the data indicates the Pfizer vaccine, which was developed in partnership with Germany’s BioNTech, is even more effective two weeks or more after the second shot.
