Delta variant leaves vaccinated, unvaccinated with similarly high viral loads: CDC
Data shows that the delta variant leaves vaccinated and unvaccinated people with similarly high viral loads, CDC Director Dr. Rochelle Walensky said in a statement Friday.
"High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with Delta can transmit the virus," Walensky said.
"This finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation" this week, Walensky said.
