By Michael Nedelman, CNN A new study shows the Delta Covid-19 variant produced similar amounts of virus in vaccinated and unvaccinated people if they get infected — illustrating a key motivation behind the federal guidance that now recommends most fully vaccinated Americans wear masks indoors. Experts say that vaccination makes it less likely that you’ll

By Maggie Fox, CNN The US has done an about-face on its approach to the coronavirus pandemic this week.
