Apr 20 MOH update
Rotavirus vaccine tied to 67% drop in serious cases of rotavirus diarrhea
The introduction of rotavirus vaccines a decade ago has cut global hospitalizations and emergency department (ED) visits among young kids for diarrhea caused by rotavirus by 67% and for all causes of diarrhea by 38%, according to estimates published this week in the Journal of Infectious Diseases.
Scientists from the US Centers for Disease Control and Prevention conducted a review of 57 studies involving patients in 27 countries since two rotavirus vaccines were licensed in 2006.
They found that hospitalizations and ED visits in children 5 years and younger for rotavirus-related diarrhea dropped 67% overall since vaccine introduction and 71%, 59%, and 60% in low, medium, and high child mortality countries, respectively. For the same age-group for all-cause diarrhea, hospitalizations and ED visits declined 38% overall and 41%, 30%, 46% in low, medium, and high child mortality countries, respectively.
An accompanying editorial notes that the study's findings coupled with new vaccine and funding efforts indicate that even more sickness can be avoided. Experts from the Chinese University of Hong Kong and the Bill & Melinda Gates Foundation note that India rolled out a new vaccine last year and expanded its reach this year. And, thanks to funding by Gavi, the Vaccine Alliance, two hard-hit African nations, Nigeria and the Democratic Republic of the Congo, will begin major immunization campaigns next year. In addition, India just licensed two new vaccines.
