World Health Organization has a recent study that proved to have a new vaccine to be useful against Ebola, proving that even Ebola (a stubborn health issue) can be dealt with when there is collaboration among the different countries.
World health experts, including those from the U.S. Centers for Disease Control and Prevention, gathered resources in the search for a vaccine. The breakthrough was reported Dec. 23 by the WHO and various partners, who in 2015 began testing a vaccine in a part of Guinea still experiencing Ebola cases. The vaccine, given to 5,837 people who were exposed in some manner to the disease, showed 100 percent effectiveness. There are still doubts regarding the vaccine’s effectiveness, such as whether it works long-term, remain. (Witchita, 2017)
