The US Centers for Disease Control and Prevention was motivated to update its guidance for fully vaccinated people after seeing a rise in the number of vaccinated people and a fall in the rates of Covid-19 cases, CDC Director Dr. Rochelle Walensky said during a virtual White House briefing on Tuesday.
"There's increasing data that suggests that most of transmission is happening indoors rather than outdoors – less than 10% of documented transmission in many studies have occurred outdoors," Walensky said.
