In the recurring, deadly Ebola outbreaks in parts of Africa, today`s health workers now have at least some tools to fight the disease: vaccines. Vaccines against Ebola have been administered to over 100,000 people to date, but they are barely out of the experimental stage. It is not known how well these vaccines will provide long-term protection across a broad population. Furthermore, on the basic scientific level, the effect of vaccination on the immune system and how the immune response of vaccinated individuals compares with that of individuals who have survived Ebola infections was not known.
