The state of California and New York City have announced plans to require government workers to get vaccinated or face weekly COVID-19 tests. These new initiatives come as the number of new COVID cases has quadrupled in the United States over the past month and are expected to keep rising for months as the highly contagious Delta variant continues to spread, particularly in areas with low vaccination rates. On Monday, the Department of Veterans Affairs became the first federal agency to require its frontline healthcare workers to get vaccinated. The American Medical Association and American Nurses Association have also joined with other medical groups calling for mandatory vaccination of all healthcare workers. In a statement, the groups said, “The health and safety of U.S. workers, families, communities, and the nation depends on it.”
