Fourth COVID-19 vaccine shots have provided a 72 percent reduction in death rates among the most vulnerable Israelis, according to new peer-reviewed research.
The finding comes from a large Israeli study that analyzed data on elderly people in care homes who received four shots, comparing them to those who only took three. It was conducted during last winter’s coronavirus outbreak, which was dominated by the Omicron variant.
The fourth shot of Pfizer’s vaccine slashed the chance of hospitalization for COVID by over 60% and delivered a 34% reduction in chances of infection, according to the study, which was conducted by Tel Aviv University, Ben Gurion University and the Health Ministry. It was published in the journal, JAMA Internal Medicine.
