luiscar/iStockphoto/Thinkstock(NEW YORK) — A preliminary study conducted at the National Institutes of Health Clinical Center determined that a potential Ebola vaccine researchers have been working on has significant promise.
Researchers published the data from the preliminary study in the New England Journal of Medicine on Wednesday. The study contained 20 participants who were given the vaccine and tested about four weeks later for the presence of Ebola-specific antibodies.
According to researchers, the participants were split into two groups, each given different dosages of the vaccine. Four weeks after vaccination, 90 percent of those given the smaller dose and 100 percent of those given the higher dose showed the presence of anitbodies against the Zaire strain of Ebola induced by the vaccine. Even when looking at the strain for which the vaccine was least effective, at least 70 percent of participants showed vaccine-induced antibodies.
None of the participants showed significant side effects, though two of 20 did develop a fever.
