Is There Gain of Function in Vaccines?

Researchers that are attempting to figure out how viruses mutate over time they could have massive problems create pandemics across the globe. The whole this is all this solution but a lot of this came out of SARS right because like we were not prepared for what happened with SARS and so I assume China was in this Wuhan lab studying those coronaviruses that cause respiratory infection. We're trying to mutate the virus to anticipate how it might show up again right. But the point is you're supposed to do it in a very secure contained environment so you can predict how a virus might mutate, he says.
