WHO Director-General: New crown vaccine development is difficult
On the 19th local time, WHO Director General Tan Desai said that there is currently no vaccine against coronavirus in the world. If the new crown vaccine is successfully developed, it will become the first coronavirus vaccine, which shows the difficulty of research and development. Tan Desai also emphasized that the new crown vaccine should be safe and provided to all people in need.
Michael Ryan, WHO health emergency project leader, said that vaccine development should not skip any step, there are no shortcuts, but some measures can be taken to accelerate research and development, and these months have demonstrated unprecedented cooperation. (Headquarters reporter Zhu He)
