Johnson & Johnson’s single-dose Covid-19 vaccine may not be authorized for use until March, weeks later than U.S. officials have suggested. The number of hospitalized patients in the U.S. was roughly flat this week, and probably will begin declining for the first time since September.

The U.K. reported the most deaths in one day since the pandemic began. Germany agreed on stricter rules for travelers arriving from high-risk nations to curb the spread of more transmissible Covid-19 strains. Turkey granted emergency approval to the vaccine developed by Sinovac Biotech Ltd. of China.
