From the Key Points: "How many SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2] infections and COVID-19 [coronavirus disease 2019]-associated hospitalizations and deaths have been prevented among vaccinated persons by the US COVID-19 vaccination program? [...] In this modeling study, COVID-19 vaccination was estimated to prevent 27 million SARS-CoV-2 infections, 1.6 million COVID-19- associated hospitalizations, and 235 000 COVID-19-associated deaths among vaccinated persons 18 years or older from December 1, 2020, to September 30, 2021. By September 30, 2021, vaccination prevented an estimated 52% of expected infections, 56% of expected hospitalizations, and 58% of expected deaths. [...] The US COVID-19 vaccination program was estimated to prevent substantial morbidity and mortality through direct protection of vaccinated individuals."
