On 1 April 2015, Lao PDR became the first country to use support from Gavi, the Vaccine Alliance to protect its children from Japanese encephalitis.

WHO coordinated clinical trials of Ebola vaccine published in New England Journal of Medicine.

In August 2014, WHO received a donation of 800 vials of the rVSV-ZEBOV ebola vaccine candidate from the Public Health Agency of Canada. While there was promising preclinical data on the candidate, only a single human had received it after a needlestick exposure in Germany. It was therefore a priority to generate safety and immunogenicity data in high quality, accelerated Phase 1 trials.

WHO identified 4 leading clinical trial sites in Gabon, Germany, Kenya and Switzerland and world leading laboratories in Germany, USA and UK and initiated a unique consortium to generate Phase 1 clinical data in exceptionally fast timelines.

The Guinean Government with WHO initiated the very first efficacy trial of an Ebola vaccine this week in an affected community of the Basse-Guinée, one of the areas where most Ebola cases are found in the country.
