About The Study: In this study of 6.3 million older U.S. adults, the mRNA-1273 (Moderna) vaccine was associated with a slightly lower risk of several adverse events compared with BNT162b2 (Pfizer-BioNTech), possibly due to greater protection against COVID-19. Future research should seek to formally disentangle differences in vaccine safety and effectiveness and consider the role of frailty in assessments of COVID-19 vaccine performance.

Authors: Daniel A. Harris, Ph.D., of the Brown University School of Public Health in Providence, Rhode Island, is the corresponding author.
