JEROME ADAMS: Viruses mutate. That's what they do. SARS-CoV-2, which is the virus which causes COVID-19, has mutated dozens of times already this year. That doesn't mean it's more dangerous. It doesn't mean it's more contagious.

So we're working with the WHO, we're working with the CDC, we're working with the UK to figure out whether this new strain of virus is going to behave any differently. But I just talked to Dr. Collins, who heads the National Institutes of Health. So far, nothing looks like it's going to change the effectiveness of this vaccine, number one. And number two, even if there is a mutation at some point which changes the effectiveness, it'll be just like the seasonal flu vaccine that we know how to tweak.
