Health maintenance organization (HMO) Clalit, the largest healthcare provider in Israel, has reported a drop of 94 per cent of symptomatic Covid-19 infections from a group of 600,000 people who have gotten both of the necessary doses of the Pfizer vaccine, according to Reuters.
HMO Clalit covers more than half of Israel’s population, and also reported that the same 600,000 people were 92 per cent less likely to come down with a serious illness as a result of contracting the virus if they had taken the vaccine.
This study, the biggest one to date in the country, represents a continuation of promising news for the Pfizer inoculation(s), as just last month (along with Moderna) Pfizer got credit for a similar effectiveness rate of 95 per cent in a New York Times report.
If you’re wondering what the measuring stick Clalit was comparing against to come up with those percentages was, Reuters reports that the group of 600,000 was set side-by-side with a similarly-sized amount of people that had matching medical histories. Also, as you can probably guess, that second group was not given the vaccine.
