What The Study Did: The findings of this study, which included 8,889 patients who received a single dose of the Ad26.COV2.S (Johnson & Johnson) COVID-19 vaccine and 88,898 unvaccinated patients, are consistent with the clinical trial–reported efficacy of Ad26.COV2.S, suggesting that the vaccine is effective at reducing SARS-CoV-2 infection, even with the spread of variants such as Alpha or Delta that were not present in the original studies, and reaffirm the urgent need to continue mass vaccination efforts globally.
