(Reuters) - U.S. healthcare workers and others recommended for the nation's first COVID-19 inoculations could start getting shots within a day or two of regulatory consent next month, a top official of the government's vaccine development effort said on Sunday.
Some 70% of the U.S. population of 330 million would need to be inoculated to achieve "herd" immunity from the virus, a goal the country could achieve by May, according to Dr. Moncef Slaoui, chief scientific adviser for "Operation Warp Speed."
