Expert: It takes at least one month to develop a vaccine and more time for test, approval

It will take at least a month to develop a vaccine for the novel coronavirus and half of a month to test it, said Li Lanjuan, a member of the Chinese Academy of Engineering, in an interview. 

And it needs at least another month and a half for final approval, she added. 

Earlier, a laboratory in Hangzhou had successfully isolated strains, which provided the basis for research and development of a vaccine for the novel coronavirus.
