The CDC announced new guidelines Tuesday that fully vaccinated individuals no longer need to wear a mask outside, except in crowded settings, and they don't need to wear a mask during small outdoor gatherings with vaccinated family and friends, or while gathering with a mixture of vaccinated and unvaccinated individuals. The agency maintains stricter guidelines for people who are unvaccinated, and the CDC continues to recommend everyone wear masks at indoor public places, saying that is still the safer course, even for those who are vaccinated. The announcement by the CDC doesn't alter the mask requirements in Boone County, said Ashton Day, spokeswoman for the Columbia/Boone County health department.
