A vaccine against the deadly Ebola virus has led to 100 per cent protection and could transform the way Ebola is tackled, preliminary results suggest.
There were no proven drugs or vaccines against the virus at the start of the largest outbreak of Ebola in history, which began in Guinea in December 2013, the BBC reports.
The World Health Organization (WHO) said the findings, being published in the Lancet, could be a “game-changer.”
The trial centred on the VSV-EBOV vaccine, was started by the Public Health Agency of Canada and then developed by a pharmaceutical company – Merck.
It combined a fragment of the Ebola virus with another safer virus in order to train the immune system to beat Ebola.
A unique clinical trial took place in Guinea. When patients were discovered, their friends, neighbours and relatives were vaccinated to create a “protective ring” of immunity.
