Evidence generated through years of research has built a solid scientific 
foundation on the safety and efficacy of rotavirus vaccines, and has served to 
raise awareness of global rotavirus disease burden and the potential impact of 
vaccination. In this commentary, we explore the role that researchers can play 
in closing key gaps of knowledge, demand, and financing to support 
decision-making on introduction of new vaccines in developing countries. With 
safe and efficacious rotavirus vaccines now on the verge of widespread adoption, 
researchers can be vital advocates for their uptake into routine immunization 
programs.
