LONDON: Initial findings on the Delta variant of Sars-CoV-2 indicate that the people vaccinated against Covid-19 may transmit the highly contagious strain as easily as the unvaccinated, Public Health England said on Friday. The findings come after concerns raised by the US Centers for Disease Control and Prevention (CDC) over people’s infectiousness amid Delta variant spread. The variant of concern, first detected in India, is rapidly becoming the dominant variant across the globe, threatening the gains made by vaccination drives. In a report published by the PHE, scientists have said that vaccination will not completely stop coronavirus transmission even as they provide high levels of protection.
