WHO announces possible existence of Ebola vaccine

Definitely the world crusade against the epidemic of Ebola is making progress. After the recent report prepared by the World Health Organization of a "real decline" in the number of new victims infected with the terrible virus in the three most affected countries (Liberia, Sierra Leone and Guinea Conakry) and the announcement by the United Nations of its total eradication in Mali, another good news was revealed by researchers: the discovery of an effective vaccine.

It is in this dynamic that the first trials of two vaccines against the most promising trial Ebola began Monday in Liberia. Good news coming from the cooperation project Americano-liberien Prevail, leading them.

It is the ChAd3, developed by the British firm GSK (GlaxoSmithKline) with the American Institute of Allergy and infectious diseases (NIAID), and VSV-ZEBOV by the public health agency of Canada (PHAC), for which the American laboratory Merck acquired the rights and cooperates with the American company NewLink Genetics.

Both vaccines have proved to prevent Ebola in animals and have been determined safe in human tests on smaller safety studies in Africa, Europe and America, according to scientists of Prevail (partnership for research on vaccines anti-Ebola in Liberia).

This is no doubt an important step in the fight against Ebola. Since its reappearance in December 2013, the killer virus killed some 9,000 people and undermined the efforts of socio-economic development of the three countries which have suffered enormously at the height of the epidemic.

The fact that the first large trials of vaccines have begun in Liberia is not random. With more than 3,700 deaths, Liberia has paid the highest price of the devastation caused by the pandemic. Arrived in the country a week ago, two experimental vaccines were so far kept in a secret location.

It is now hoped that the effective implementation of this scientific project will bring to term a probative response to the mystery that surrounds this deadly disease that scares around the world and for which there is no vaccine.

The goal is to achieve the future eradication of the virus.
