Rotavirus-related diarrhoea kills mostly in developing countries, but vaccine roll outs have begun

25 October 2011 – According
to the latest rotavirus mortality estimates published today in the Lancet Infectious Diseases,
rotavirus still takes the lives of 453,000 children each year, more than 1,200 every day.
These new figures highlight the heavy death toll caused by rotavirus-related
diarrhoea among children under five. Ninety five percent of these deaths occur
in developing countries, where limited access to treatment makes children most
vulnerable to this killer disease.
The support GAVI Alliance offers for rotavirus vaccines brings hope to countries where the most deaths occur. The affordable and financially sustainable introduction of rotavirus vaccines in national immunisation programmes are expected to have a dramatic impact on global mortality due to rotavirus diarrhoea.
In September 2011, GAVI approved rotavirus vaccine funding for 16 more countries,
including two of the 10 countries with the greatest number of rotavirus
deaths worldwide: Angola and Ethiopia. These two countries will soon begin to reverse this tragic outcome with the introduction of
rotavirus vaccines. By 2015, GAVI plans to support the introduction of this life-saving vaccine in some 40 countries, many of them in Africa, where the death toll from rotavirus infections is extremely high.
Swift and significant declines in
hospitalisation and deaths due to rotavirus and all-cause diarrhoea have been
observed in many of the 30 countries that have introduced rotavirus vaccines
into their national immunisation programmes. For example, In Mexico, diarrhoeal
deaths in children five years of age and younger plummeted by 46% during
2007-2009, in the three years following vaccine introduction (1).
The reduction of severe and fatal diarrhoea following the introduction of
rotavirus vaccines underscores the incredible potential for rotavirus vaccines
to save children’s lives. Five GAVI-eligible countries have already introduced
rotavirus vaccines: Nicaragua, Bolivia, Honduras, Guyana, and Sudan.
