1. As ayoung boy my Aunt gave me a model kit for my birthday. A four foot high DNA molicule. That was likley the last time I spent hours pondering DNA, but I understand that #COVID19 is an RNA virus and has only a single helix unlike DNA that is a double helix.
2. Relenave as I understand and as explained by Dr Cheng in Shanghai, is the single helix is much more capable of mutation. Dr Cheng reports 8 variants of #COVID19 and thus difficult to find a vaccine. It’s not ending soon. So we may need to fight it with the tools we have.
