Israeli research carried out before the emergence of the Omicron variant of the coronavirus found that people over the age of 50 who received a third dose of the Pfizer-BioNTech vaccine had 90 percent lower mortality than those who did not get the booster.
The research, based on data from the Clalit health maintenance organization and published in the New England Journal of Medicine, examined those who had received their second dose of the vaccine at least five months earlier. Clalit is the largest of Israel’s HMOs.
