There has been approximately one year since an Ebola outbreak affected the populations in western Africa. Scientists have been working from that point on to find a cure for this epidemic. The Ebola virus disease is a viral hemorrhagic fever that can be contacted through an open wound from an infected being. This disease can kill between 25 and 90% of its victims, and there are probably the fruit bats that carry this virus in nature without developing its deadly symptoms. The good news is that one of the vaccine trials has finally ended with promising results. The scientists are already talking about an effective vaccine.
In 2014 only, Ebola killed around 11,000 patients in Africa. Fortunately, after a year of trials, the World Health Organization announced the discovery of an effective vaccine against such a deadly virus. However, the research is only at its initial stage. These impressive results were only recorded under medical trial circumstances. The medicine will have to go through other tests and paperwork until it is approved for safe public purposes.
The estimated release year of the first Ebola vaccine is 2018. The serum was already administered in 2015 to around 6,000 people in Guinea. Until now, none of the exhibited any symptoms of the Ebola virus. The effective virus is known as rVSV-ZEBOV, and it proved to protect people. However, the protection works when the serum is administered 10 or more days before people are exposed to the deadly virus. This way, the vaccine works more efficient as a preventive solution and not a cure. The composition has just finished the stage three of a medical trial. This means that the serum was already tested on hundreds of participants. Furthermore, it also proved to be safe and efficient.
The official trial designated its participants into 117 clusters. Among these, 70 groups received the vaccine on the spot while the other 47 clusters got the serum 21 days later. None of the participants developed the disease after an Ebola infection. Furthermore, the study surprised another key element. Even though only 52.1% of the participants were vaccinated, there was a 70.1% rate of success in preventing the presence of the virus. This extensive protection was possible thanks to a phenomenon known as the herd immunity. The vaccinated persons protected those ineligible for vaccination also.
However, even though the test results were more than satisfactory, the new effective vaccine might not work 100% in real life. The biology of each person is different, and no serum can guarantee the safety of all beings. Nonetheless, humanity will more than likely get rid of yet another deadly virus in the near future.
