This article in USA Today confirms my suspicions that all the anti-COVID measures would drastically reduce the prevalence of seasonal flu in the U.S.:
During the 2019 flu season from Sept. 29 to Dec. 28, the CDC reported more than 65,000 cases of influenza nationwide. During the same period last year, the agency reported 1,016 cases.
I get a vaccine every year for the flu—and luckily have not caught it since I was in elementary school—but other than that, I never think about it. My dream right now is that the COVID vaccine be the same kind of thing: a prick on the arm once a year, and otherwise nothing much to think about.
