First FDA-approved vaccine for the prevention of Ebola virus This is very important news for anybody who travels to central Africa.
The U.S. Food and Drug Administration announced today the approval of Ervebo, the first FDA-approved vaccine for the prevention of Ebola virus disease (EVD), caused by Zaire ebolavirus in individuals 18 years of age and older. Cases of EVD are very rare in the U.S., and those that have occurred have been the result of infections acquired by individuals in other countries who then traveled to the U.S., or health care workers who became ill after treating patients with EVD.
This is good news.
