The Pfizer and AstraZeneca coronavirus vaccines reduce the risk of death from the Delta variant by 90%, a new U.K. study finds.
The Delta variant is now the dominant form of the coronavirus in the United States, the United Kingdom and many other countries.
The study collected data from 5.4 million people in Scotland between April 1 and Sept. 27, 2021, is the first country-wide assessment of the effectiveness of vaccines in preventing death from the Delta variant.
