From January 31st –
The disease progression in of 2019-nCoV is consistent with those seen in animals and humans vaccinated against SARS and then challenged with re-infection. Thus, the hypothesis that 2019-nCoV is an experimental vaccine type must be seriously considered.
In the worst-case scenario, if the vaccination strain is more highly contagious and lethal, 2019-nCoV could become the worst example of vaccine-derived contagious disease in human history. With an uncharacteristic aysmptomatic prodromal period of 5-7 days, individuals returning from China to other countries must be forthright and cooperative in their now-prescribed 2-week quarantine.
