Most Americans should get an updated COVID-19 vaccine, health officials said Tuesday.

       Advisers to the Centers for Disease Control and Prevention endorsed the new shots for everyone 6 months and older and the agency’s director quickly signed off Tuesday on the panel’s recommendation. That means doses should be available this week, some as early as Wednesday.

       The severity of the COVID-19 pandemic has faded, but there are still thousands of hospitalizations and hundreds of deaths in the U.S. each week. Hospitalizations have been increasing since late summer, though the latest data indicate infections may be starting to level off, particularly in the South.
