The confluence of coronavirus disease 2019 (COVID-19) and seasonal influenza this fall and winter will result in considerable morbidity and mortality, stressing the health system. With more than 100 000 COVID-19–related deaths already, the US could see a second wave of disease later this year. In 2018-2019 (a “moderate” year for influenza), the US experienced 35.5 million influenza cases, with 490 600 hospitalizations and 34 200 deaths related to influenza.1 An effective COVID-19 vaccine is unlikely until 2021. Even though seasonal influenza vaccines have variable year-to-year effectiveness, they can significantly reduce morbidity and mortality, especially with high coverage.
