Johnson & Johnson, the US pharmaceuticals, medical devices and consumer products giant, is developing a preventive Ebola vaccine and offering funds and training to Chinese doctors working in areas most affected by the disease.

More than 1,000 Chinese medical workers have been working or will be dispatched to areas affected by the outbreak.

"Johnson & Johnson is honored to participate in these activities to show our respect to the Chinese doctors, and we will continue to give them professional services and other support," said Jesse Wu, chairman of Johnson& Johnson China.
