Antibodies post vaccine can fight Delta variant
Washington, August 18
The Delta variant of the SARS-CoV-2 virus is unable to evade the antibodies generated by vaccination, according to a lab study. The findings, published journal ‘Immunity’, help explain why vaccinated people have largely escaped the worst of the Delta surge.
Researchers at Washington University School of Medicine in the US analysed a panel of antibodies generated by people in response to the Pfizer Covid-19 vaccine and found that Delta was unable to evade all but one of the antibodies they tested.
Other variants of concern, such as Beta, avoided recognition and neutralisation by several antibodies, they said. In previous studies, Ali Ellebedy, an associate professor at Washington University, had shown that both natural infection and vaccination elicit lasting antibody production. — PTI
