Covid-19 Vaccinations Cut Hospitalizations and Deaths, U.K. Finds

February 22, 2021

(The Wall Street Journal) – The U.K.’s rollout of Pfizer Inc. and BioNTech SE’s Covid-19 vaccine has led to a substantial drop in infections in people 80 and over, according to preliminary data that adds to a growing body of evidence that the shots provide significant if not complete protection against the disease. The data from the U.K., published Monday, is preliminary and hasn’t been reviewed by other scientists. It provides reasons for optimism that vaccines offer a route out of a pandemic that has claimed at least 2.5 million lives world-wide and sickened tens of millions.
