JERUSALEM, March 28 (Xinhua) -- A study of COVID-19 vaccine recipients in Israel has found that among people aged 60 and over, receiving a second booster shot reduces the death risk by 78 percent compared to only receiving one booster, the country's Clalit Health Services said Monday.
The retrospective analysis was conducted by Clalit and Ben-Gurion University for a 40-day period starting Jan. 10, and its findings were published last week on the preprint platform Research Square.
