UK study finds vaccinated people easily transmit Delta variant in households

The Delta coronavirus variant can transmit easily from vaccinated people to their household contacts, a British study found on Thursday, although contacts were less likely to get infected if they were vaccinated themselves. The Imperial College London study illustrates how the highly transmissible Delta variant can spread even in a vaccinated population. The researchers underlined that did not weaken the argument for vaccination as the best way of reducing serious illness from COVID-19 and said booster shots were required.
