President Joe Biden announced Thursday that his administration will require all civilian federal workers provide their Covid-19 vaccination status or face strict testing measures, social distancing and masking requirements and limited travel.

The new rule comes as Covid cases are rising again in all 50 states due to the highly contagious delta variant and vaccination rates have leveled off. In the U.S., 69.3% of adults have received at least one dose of the vaccine, according to the Centers for Disease Control and Prevention.
