I think Corona virus itself is stomping out the common cold by means of us all being more cleanly. I'm sanitizing after I Go Everywhere, I don't even touch a gas pump I use a paper towel. I wear a mask when I'm around a bunch of people I don't know. I haven't been sick since this bullshit started year ago. So I don't think it has anything to do with a vaccine more than it does with people being "clean".
