The director of the US Centers for Disease Control and Prevention reiterated that unvaccinated Americans should continue to wear masks and practice social distancing, encouraging them to get vaccinated as soon as possible.
"The science is also very clear about unvaccinated people. You remain at risk of mild or severe illness, of death, or spreading the disease to others. You should still mask, and you should get vaccinated right away," Dr. Rochelle Walensky said.
Walensky added that if Covid-19 conditions worsen in the US, today's new mask guidance for fully vaccinated people could be rolled back.
"We know that the more people are vaccinated, the less cases we will have and the less chance of a new spike or additional variants emerging," she said.
