  ABSTRACT: Background: Although pneumococcal vaccination prevents the most common pneumonia of bacterial etiology, its associations without comes of Acute Coronary Syndrome (ACS) are unknown. Methods: This is a prospective cohort study of 1436 patients hospitalized with suspected ACS/non-ST elevation MI that were eligible for pneumococcal vaccination. Primary outcomes were death and subsequent Myocardial Infarction (MI) within 6-months of the index hospitalization. We used Cox regression to assess associations between pneumococcal vaccination and outcomes, adjusting for influenza vaccination and relevant clinical covariates. We also utilized propensity scores to adjust for potential confounding. Results: Overall, 937 (65.3%) patients received pneumococcal vaccination either prior to or during the index hospitalization. Unvaccinated patients had higher mortality (26.9% vs. 7.9%; p
