It is important cause if lots of people have vaccinations people are less likely to get it due to being in a herd, and literally people don’t want to catch any diseases. History Of Ebola!! ■ In 1976, Ebola (named after the river) first emerged in Sudan and Zaire. The first outbreak of Ebola infected over 284 people, with a mortality rate of 53%. ■ A few months later, the second Ebola virus emerged from Yambuku, Zaire. ■ Data also suggests Ebola existed but factors like population growth, and direct interaction with wildlife may have contributed the spread of EBOLA! Ebola Vaccine Development ■ The Ebola vaccine was developed by Johnson & Johnson and was urgently deployed with a 95-100% chance of effectively working. ■ In October 2014 there were trials of the vaccine but in Geneva, Switzerland there were developed vaccine-related arthritis ■ In April 2015, they conducted phase 3 trial which was proven successful then was deployed ‘Ring Vaccination Protocol’ Effectiveness of Vaccination Program (Does it exist still?) ■ The developed vaccine for Ebola, wiped out most of the cases of it during the major outbreaks. ■ It is still around in West Africa even today there have been 2,100 cases of Ebola since last August and more than 1,400 deaths, which is the 2nd worst Ebola outbreak ever. ■ After the 2014-16 West Africa epidemic which affected 28,000 people, which was to happen in an active war zone.
