Reasons to be optimistic about the Coronavirus provided by Peter Diamondis (1) We know the disease is mild in most people who get it. At least 80%, most likely more, won’t have an illness bad enough to warrant hospitalization. We’ll have a better idea once testing is more broadly applied, but it would not surprise me if the widely cited case fatality rate of 1-2% is eventually less than half that. (2) Children seem particularly protected from severe coronavirus disease. Many of the sniffles and colds kids experience are due to existing milder coronavirus strains, possibly giving them partial immunity to this more serious new threat. (3) There has been extraordinary global cooperation from doctors, scientists and public health officials. In most cases, this has included remarkable sharing of clinical data and research. It is wonderful to see the medical community responding in such a unified voice, all of us trying to solve this new problem.

Well the first daft comment I read is that children are particularly protected because they have been exposed to milder coronavirus strains...ok so why have we as adults lost that immunity?  Isn't it the case that once a human has antibodies for a particular condition, they never lose them?  

But are you seriously going to be a guinea pig for a vaccine designed in less than 3 months?  Unless the Chinese have divulged how they made it in the first place, this is nonsense.
