The Centers for Disease Control and Prevention is expected to recommend Tuesday that fully vaccinated people begin wearing masks indoors again in places with high Covid-19 transmission rates, according to people familiar with the matter.

Federal health officials still believe fully vaccinated individuals represent a very small amount of transmission, according to the sources. Still, some vaccinated people could be carrying higher levels of the virus than previously understood and potentially transmit the virus to others, they said.

The updated guidance comes ahead of the fall season, when the highly contagious delta variant is expected to cause another surge in new coronavirus cases and many large employers plan to bring workers back to the office.

"Get the shot so life can go back to normal," they said.

"Get the shot and you can take that awful mask off," they said.

"Get the shot and keep your mask on," they're now saying.

What will they be saying next week?

I've got a hunch, and that hunch is this: They're gonna have a hard time getting people to mask up this time. I don't think Americans will be willing to endure a lockdown round 2.
