Novel coronavirus vaccine still months away: Scientists

The video discusses how research on MERS and SARS can inform vaccine development strategies against the Wuhan coronavirus. It highlights nucleic acid vaccine technology, which uses viral DNA or RNA, as a promising approach. The process of creating vaccines involves constructing antigens for the immune system to target the virus, followed by animal and human trials to ensure safety and efficacy. Challenges include the lack of isolated virus samples and suitable animal models. The video stresses the importance of global virus surveillance and the need for adaptable vaccine technologies to combat future epidemics.

What challenges do scientists face in testing the vaccine?

Why is better global surveillance of viruses important according to the authors?
