A top infectious disease official says there's hope that a vaccine against Ebola will be available as early as next July.
Dr. Anthony Fauci of the United State's National Institutes of Health says such a preventive vaccine has been successfully tested with monkeys.
Fauci told CBS This Morning that human trials with volunteers will commence in September, and by July it should be ready.
He also says people shouldn't have concerns that two infected patients were brought to the US from West Africa, saying they can be handled safely.
More than 1300 people have been stricken in West Africa, and nearly 730 have died in Guinea, Liberia and Sierre Leone.
Ebola currently has no vaccine or antidote. It is contracted through close contact with bodily fluid and blood, unlike other airborne viruses.
