Coronavirus live updates: WHO says 172 countries in on global vaccine plan; Chinese e-commerce giants see a boost

Scientists are expressing some doubts about the Food and Drug Administration’s emergency use authorization for convalescent plasma as a treatment for Covid-19 patients. In a Sunday news briefing, President Donald Trump touted the treatment as a “breakthrough.” Former FDA chief Dr. Scott Gottlieb told CNBC that while there was enough data to justify the authorization, the treatment is not a “home run.” 

The following data was compiled by Johns Hopkins University:

• Global cases: More than 23.4 million
• Global deaths: At least 809,300
• U.S. cases: More than 5.7 million
• U.S. deaths: At least 176,800
