There are more and more mixed messages on masks, even for those vaccinated against COVID-19, the CNN website reports today (June 29, 2021).
The World Health Organization is encouraging even the vaccinated to keep the masks on -- especially indoors -- as the Delta variant of COVID-19 ricochets around the world.
On the other hand, the U.S. Centers for Disease Control and Prevention a month ago told vaccinated Americans they could largely take the masks off, indoors and out.
