A third dose of coronavirus vaccine reduces the risk of death from COVID-19 by 90% among patients aged 50+, according to a new study by Israeli scientists. The Jerusalem Post reports.
The study was carried out by the Clalit Health Insurance Fund, Ben-Gurion University and Sapir Academic College. The findings were published in the New England Journal of Medicine.
A team of scientists analyzed data from the Clalit Health Insurance Fund using advanced statistical methods to determine the effectiveness of the third dose of Pfizer vaccine in preventing mortality.
Among those who received three vaccines, there was an average 90% reduction in mortality (88% for men and 94% for women) compared with patients who received two doses of the vaccine.
& quot ; The results of our study clearly show that booster vaccination is significantly associated with a reduction in the risk of death from coronavirus, including from the Delta strain. These results provide important research-based information for people in Israel and elsewhere who are still undecided about the introduction of a third vaccine, '' said Dr. Doron Netzer, who led the study.
The study was conducted from August 6 to September 29. More than 800,000 Clalit patients aged 50+, two-dose vaccinated were divided into two groups based on whether they received the third vaccine or not. The data were matched for age, sex, socioeconomic status and comorbidities. The average age of the participants was 68.5 years. .
It is noted that this is the world's largest study on this issue.
