About The Study: In this study that included 3.4 million adults, co-administration of the BNT162b2 BA.4/5 bivalent mRNA COVID-19 vaccine (Pfizer-BioNTech) and seasonal influenza vaccine was associated with generally similar effectiveness in the community setting against COVID-19–related and seasonal influenza vaccine-related outcomes compared with giving each vaccine alone and may help improve uptake of both vaccines. 

Authors: Leah J. McGrath, Ph.D., of Pfizer Inc., in New York, is the corresponding author.
