A Leaked Report Shows Pfizer’s Vaccine Is Conquering Covid-19 in Its Largest Real-World Test

February 22, 2021

(MIT Technology Review) – A leaked scientific report jointly prepared by Israel’s health ministry and Pfizer claims that the company’s covid-19 vaccine is stopping nine out of 10 infections and the country could approach herd immunity by next month.  The study, based on the health records of hundreds of thousands of Israelis, finds that the vaccine may sharply curtail transmission of the coronavirus. “High vaccine uptake can meaningfully stem the pandemic and offers hope for eventual control of the pandemic as vaccination programs ramp up across the rest of the world,” according to the authors.
