GENEVA: The hunt for an Ebola vaccine will produce data soon about whether two experimental vaccines are safe and could lead to larger medical trials in West Africa by January, a top World Health Organization official said Tuesday.

Dr. Marie Paule Kieny, an assistant director general for WHO, said clinical trials either planned or underway in Europe, Africa and the US are expected to produce preliminary safety data by December. In the meantime, she said, governments are pushing for immediate “real-world use” of an approved Ebola vaccine.
