WHO chief says U.S., Saudi discussing MERS vaccine
Margaret Chan said there were many gaps in the science of MERS and so far the world had taken only "baby steps" in tackling the virus.
She said cases in Saudi Arabia and South Korea showed that infection control in hospitals was not good enough, one of many examples where countries were failing to meet their obligations to protect public health.
