In a small trial, an experimental vaccine protected 100 percent of people at high risk for Ebola. But more data are needed to figure out exactly how well the vaccine works.
The first vaccine against a parasite — one that causes malaria — was recommended for approval. It's not as effective as researchers had hoped, but they still think it could make a big difference.
