Well, ye see, the COVID 19 is basically a ball with a bunch of prongs sticking out all over the place. What you need is an anti-virus. Another ball with all holes, but with inert RNA. What you want is to dress up your anti-virus all sexy like, and introduce it into the CV19 population and let nature do its thing.
Once the CV19s pair up with the barren females their RNA isn't going anywhere and they die, like a couple in a loveless marriage.
LOL, you should write children’s books!
