this report is from a very credible place and it also sounds like an entirely plausible explanation why they are doing so well at developing the vaccine
still and all, my best guess is that the various governments will require more than 90 days testing before mass marketing begins
(selective availability on some sort of high risk test basis...could happen faster, however, but exactly how such determinations would be made for a vaccine ...as opposed to a treatment... I am uncertain?)
Best countries for a quick test:
China
S Korea
Italy
