COVID-19: Symptomatic Cases Drop By 94% With Pfizer Jab, Study Shows

Symptomatic cases of COVID-19 are dropping by 94% after two doses of the Pfizer vaccine, according to the largest study of real-world data from Israel.

Research by Clalit, the biggest healthcare provider in Israel, shows that the Pfizer vaccine is equally effective for all age groups, with preliminary data showing a 94% drop in symptomatic cases and a 92% drop in serious cases.

Clalit analysed 1.2 million people - 600,000 of who had received two doses of the Pfizer jab and the same number who had not. Israel's detailed digital collection of patient data allowed scientists to match the two groups.

Professor Ran Balicer, founding director of the Clalit Research Institute said: "It's now unequivocally clear that Pfizer's coronavirus vaccine is extremely effective in real life a week after the second dose, just as was found in the clinical trials."
