"South Africa and the variant discovered there offer a powerful example. Recent research suggests that the highly contagious variant is less responsive to at least four vaccines." This from the New York Times.https://www.nytimes.com/2021/01/31/world/africa/coronavirus-south-africa-variant.html Like I've said. There is a solution that no-one is looking at. It's in my video and in my book, A User Manual for Life On Earth. https://www.smashwords.com/books/view/1029328 The book contains R130 million of Research over a 22 year period. It is available for $4.95 or you can get it free if you can't afford the $4.95. If you get more value out of it, then you can pay more, eg buy another book at a higher price.
