The World Health Organization (WHO) has revealed that the Ebola virus has killed over 11,000 people in West Africa so far. A restructured Ebola vaccine independently developed by China has entered phase two clinical trials in Sierra Leone, West Africa, marking the vaccine's first overseas clinical trial permit.
The Chinese Ebola vaccine has three major features- first, the vaccine is the first based on the Ebola virus strain responsible for the West African outbreak in 2014. Until now, all tested Ebola vaccines were based on a virus strain from the Democratic Republic of the Congo outbreak of 1976.
Second, the Chinese vaccine is currently in the form of a freeze-dried powder which will keep it stable for at least two weeks in temperatures of up to 37 degrees Celsius. This will also make it suitable for the tropical West African region and assist with large-scale production.
