LOS ANGELES, April 26 (Xinhua) -- Millions of unused COVID-19 doses in the United States are set to go wasted as the country's vaccination rates continued to decline amid an uptick of new infections.
Since the emergency use authorization of the first COVID-19 vaccines in the country last winter, federal data show that U.S. states received a staggering 720 million COVID-19 doses, and more than 570 million of those shots have been administered, according to a report of ABC News.
