COVID Booster Cuts Death Rate by 90%, Israeli Study Finds

An Israeli study tracked more than 843,000 people who received two doses of the Pfizer vaccine — and then explored whether the results improved for the 758,000 who then also got a booster shot.

The results? HealthDay reports:
Boosted folks are 90% less likely to die from a Delta infection than people relying solely on the initial two-dose vaccination, Israeli data show.

That protection will be critically important during the next couple of months as the Delta variant continues to dominate throughout the United States, said Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases.

A second study out of Israel focused on infection and severity of illness, and it also produced good tidings for boosters in the face of the Delta variant. This study involved nearly 4.7 million Israelis who'd been fully vaccinated with Pfizer and were eligible for boosters. Confirmed infections were tenfold lower in the group of people who got the Pfizer booster, researchers reported. Further, results showed that the longer a booster was in a person's system, the more resistant they became to infection from the Delta strain.
