Dr. Rochelle Walensky, director of the US Centers for Disease Control and Prevention, said the agency's guidance for people who have been vaccinated against Covid-19 is still in the works and coming soon.
"These are complex issues and the science is rapidly evolving. CDC is working to ensure that the communication we release on this guidance are clear and that the American public can act on them," Walensky said during Friday's virtual White House briefing.
The guidance had been expected to release this week.
"Our goal and what is most important is that people who have been vaccinated and those not yet vaccinated are able to understand the steps they can take to protect themselves and their loved ones," Walensky said. "We will be releasing this guidance soon."
