An Israeli healthcare provider that has vaccinated half a million people with both doses of the Pfizer vaccine says that only 544 people — or 0.1% — have been subsequently diagnosed with the coronavirus, there have been four severe cases, and no people have died.
That means the effectiveness rate stands at 93 percent, Maccabi Healthcare Services announced on Thursday, after comparing its immunized members to a “diverse” control group of unvaccinated members.
Full protection against COVID-19 for people who have been vaccinated is believed to kick in a week after the second shot, so the Maccabi data covers all those of its members who are seven or more days after receiving that second dose.
Maccabi’s statistics are being closely monitored around the world, for giving the first major insight into how the vaccine performs outside of clinical trials. And they are being widely hailed for indicating that real-word effectiveness is close to the 95% efficacy cited after Pfizer’s clinical trials.
“This data unequivocally proves that the vaccine is very effective and we have no doubt that it has saved the lives of many Israelis,” said senior Maccabi official Dr. Miri Mizrahi Reuveni after the new data release.
