The pace of coronavirus vaccinations continued to accelerate over the weekend. The number of shots surpassed four million in a single day on Saturday, a first. The seven-day average exceeded three million for the first time, according to the Centers for Disease Control and Prevention. The increase came as President Biden pushed to make enough COVID-19 vaccines for every American adult by the end of May. Although coronavirus infections and deaths have fallen from their winter peaks, the numbers have spiked again recently in many states, especially in the Midwest and the Northeast. Public health experts disagreed on Sunday news talk shows about whether the increases indicated that the nation was heading into a fourth wave. Elsewhere, India's health ministry reported over 100,000 new COVID-19 cases Monday, making India the second country after the U.S. to report that case level in a single day.
