Opinion: A winter pandemic wave is looming. Get the booster.

Will there be an autumn or winter wave of covid? Right now, in the United States, daily cases and deaths are gradually declining off a still-high plateau. On the horizon, however, there are worrisome signals of a possible new wave. It is not too soon to grab protection with the bivalent booster. Europe is a telltale indicator. For the past few weeks, cases among people 65 years and older have been on the rise in 19 of the 26 countries reporting data to the European Center for Disease Prevention and Control. Fifteen countries in the group reported rising hospitalizations. Germany, France and Italy have all seen growing caseloads, which often portend a similar jump in the United States a few weeks later.
