One dose of Pfizer’s COVID-19 vaccine still leaves recipients vulnerable to variants: U.K. study
2021-04-30 from theglobeandmail.com
Researchers in Britain have found that one dose of the Pfizer-BioNTech vaccine provides insufficient protection against new variants of the COVID-19 virus and urged public health officials to be vigilant about ensuring that people receive a second injection.
“We’re looking rather vulnerable to variants after one dose,” said Danny Altmann, a professor of immunology at Imperial College London who co-authored the research.
Dr. Altmann said the findings were especially relevant to countries such as Britain, where most people have had only one dose of a vaccine so far. More than 34.2 million people in the United Kingdom have had one shot and 14.5 million have had two.
“For the situation of countries like the U.K., we’re saying hang on a minute, those people are doing well at the moment, and the U.K. has done well, but watch out and keep your eye on the ball for the variants because [people] are far more vulnerable than you might have expected to the variant strains,” he told a media briefing on Friday.
