Médecins Sans Frontières or MSF vaccinate a large scale of South Sudanese refugees against cholera in Gambella region of Ethiopia to protect them and the host community.
MSF in its statement on Monday said United Nations or UN High Commissioner for Refugees registered 185 thousand refugees.
It blamed overcrowding and the poor sanitation as perfect breeding ground for the cholera virus.
MSF teams administered the first dose between July 24 and August 2 to refugees in Lietchuor, Kule and Tierkidi camps and to newly arrived refugees in Pagak, Pamdong and Matar transit centres.
It said the vaccine is given in two doses to protect the host population against the disease due to the movement of people and trade between the camps and surrounding villages.
