Rotavirus vaccines lead to significant reductions in severe and fatal diarrhea in both vaccinated and unvaccinated children
Rotavirus vaccines are saving lives and improving health in countries where children have access to them. Swift and significant declines in hospitalization and deaths due to rotavirus and all-cause diarrhea have been observed in many of the countries that have introduced rotavirus vaccines into their national immunization programs. Researchers also have found that use of rotavirus vaccines may protect unvaccinated children and adults by reducing transmission of rotavirus from the vaccinated population to unvaccinated members of the community (an effect called herd immunity). These remarkable results underscore the incredible potential for rotavirus vaccines to improve child health and save children’s lives.
