Delta variant produces similar viral loads in vaccinated, unvaccinated: Study

The study demonstrated that Delta infection resulted in similarly high SARS-CoV-2 viral loads in vaccinated and unvaccinated people, said CDC Director Rochelle Walensky.

Washington: A new study of the US Centers for Disease Control and Prevention (CDC) shows the Delta variant produced similar amounts of virus in vaccinated and unvaccinated people if they get infected. The study, published by the CDC on Friday, focused on 469 COVID-19 cases identified among Massachusetts residents who had travelled to Barnstable County, a summer vacation destination, during July 3 to 17, the Xinhua news agency reported. A total of 346 cases, about 74 percent, occurred in fully vaccinated people, according to the study.
