 Paul's on an FDA advisory committee for the COVID vaccines. We had a meeting last Thursday, which was a nine hour meeting. It was shown on C-SPAN. Oh, that is a long meeting. But anyway, so we asked Paul, what is mumps? And how is it contagious? In the same way that SARS-CoV-2 is contagious, which is it spreads by small respiratory droplets that emanate from the mouth and nose. So like coughing, sneezing, talking, kissing. And mostly the virus infected children.
