Potential COVID19 vaccines not affected by recent mutations: Study

Vaccines currently being developed for COVID-19 should not be affected by recent mutations in the novel coronavirus, according to researchers, including one of Indian origin, who said the finding is good news for the hundreds of vaccine candidates around the world.The researchers, including those from the University of York in the UK, noted that most vaccines under development worldwide have been modelled on the original ‘D-strain’ of the virus, which were more common amongst sequences published early in the pandemic.Since then, the virus has evolved to the globally dominant ‘G-strain’, which now accounts for about 85 per cent of published SARS-CoV-2 genomes, they said.There had been fears the G-strain, within the main protein on the surface of the virus, would negatively impact on vaccines under development.However, the research by Australia’s national science agency the Commonwealth Scientific and Industrial Research Organisation (CSIRO), found no evidence the change would adversely impact the efficacy of vaccine candidates.
