Several years ago, my former employer took on a contract to manufacture an experimental 'compound' for HIV prevention in Africa, for the Gates Foundation. After watching an operator nearly slip on a small spill of the material on the floor, I asked someone 'what is that stuff?"... Turned out it was a kind of personal lubricant. Ever since that day, I've never held the belief that Bill Gates was terribly bright. #truestory.
If he's saying everyone should get a vaccine, make sure someone like Merck / J&J or BMS has manufactured an actual vaccine, whose RNA matches the virus.
