MOSCOW – The Delta COVID-19 strain spreads as easily as chickenpox, with fully vaccinated people also transmitting the virus, The Washington Post has reported, citing an internal document from the US Centres for Disease Control and Prevention (CDC), expected to be published later on Friday.
The transmissibility of the Delta variant is almost as high as chickenpox, with each infected person, on average, infecting eight or nine others, according to the document.
Fully vaccinated people can transmit the virus as well as unvaccinated people, it also said. Vaccination, however, provides substantial protection against the virus, the document added.
