Second COVID vaccine booster significantly lowers death rate, Israeli study shows

Senior citizens who received a second booster of the Pfizer–BioNTech COVID-19 vaccination had a 78% lower mortality rate from the disease than those who got one only, a study from Israel showed on Sunday. The country's largest healthcare provider, Clalit Health Services, said the 40-day study included more than half a million people aged 60 to 100. Some 58% of participants had received a second booster - or two shots in addition to the basic two-shot regimen. The remainder had received only one booster.
