Ebola Vaccine Debuts

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, BBC repportd.

The World Health Organization (WHO) said the findings, being published in the Lancet, could be a “game-changer”.

Experts said that the results were “remarkable”.

This trial centred on the VSV-EBOV vaccine, which was started by the Public Health Agency of Canada and then developed by the pharmaceutical company, Merck.

It combined a fragment of the Ebola virus with another safer virus to train the immune system to beat Ebola.

A unique clinical trial took place in Guinea. When a patient was discovered, their friends, neighbours and family were vaccinated to create a “protective ring” of immunity.

This could be the breakthrough the world has been waiting for.

There is caution as the results are still preliminary, with more data coming in.

But officials at the WHO believe the effectiveness of the vaccine will end up being between 75 per cent and 100 per cent.

If such a vaccine was available 18 months ago then thousands of lives could have been saved.

There are still other vaccines being trialled – notably from GSK and Johnson&Johnson – although as the number of cases continues to fall it is becoming increasingly difficult to prove how effective they are.
