We have a local vaccine center here ...who already had a vaccine effort for SARS, so they quickly came up with a patch type (protein needles) vaccine that produces antibodies in mice... we deal with the mind boggling logic that volunteers cannot trial vaccines and be intentionally exposed (not even 20 or 25) because it creates an ethical dilemma...At the pace we're talking about for actual distribution of a viable vaccine (that may never come), everyone will have herd immunity, and I would be surprised if the death rates by country in the end are much different.
David, at the risk of being super-cynical ("moi??") can you extrapolate from your comments and consider a less-than-ethical superpower, not far from your western borders, who WOULD 'accidentally' trial any given promising vaccine (on dissidents, say?)... If successful, where would that put them in terms of dominance?
Maybe I'm just too stir-crazy, depressed and Orwellian....
