A new COVID vaccine is due out next month, but health experts and analysts say it is likely to be coolly received even as hospitalizations from "Eris", a variant of the Omicron form of the coronavirus, rise around the country. Some public health experts hope that Americans will welcome the new shot as they would a flu jab. In the fall of 2022, by which time most people had either had the COVID virus or the vaccine, fewer than 50 million people got the shots.
