Is there any data on how younger people with underlying diseases handle this illness? I've only seen mortality by age for the whole population. E.g. are children with cancer as likely to die from this as old people with cancer?

What are the chances of creating a vaccine that gives lasting protection? I've heard so much about some people getting reinfected and the virus mutating that it's starting to seem likely that making a vaccine would be hard.

Also, do you think that there is a large number of unidentified cases of people having milder symptoms?

Thank you for your excellent work!!
