A rush of Israeli medical research — some emerging too fast for academic journals to keep up — reveals that the Pfizer-BioNTech vaccine is even more effective than hoped at preventing serious disease and death, safe for nearly all adults, and almost completely free of serious side effects.
Israel’s scientific results have allowed health officials to open the inoculation program to pregnant women and nursing mothers, while the findings also showed that it was safe for those with food allergies and autoimmune diseases.
And the vaccine has proved so good at protecting the elderly, who are especially vulnerable, that hospital administrators here say it has all but eliminated the risk that covid-19 cases would collapse their critical care systems. Almost 90 percent of Israelis over 50 have been fully vaccinated.
Israel’s small population of about 9 million, and its universal national health system, makes it a natural vaccine lab for the world.
“Sometimes when you go from clinical trials to the real world, you get different results,” said Hagai Levine, an epidemiologist at Hebrew University and chairman of the Israel Association of Public Health Physicians. “What these studies are showing us is the vaccine gives very good protection against disease and mortality. That is great news for the world.”
