Wild times ahead…
Current hypotheses include that a covert SARS vaccination program was included in the national mandatory vaccination program started on Dec 1, 2019 that happened to involve a secondary true outbreak of Coronavirus with secondary exposure. Under such conditions, the animal models clearly show that vaccination against SARS spike proteins lead to high rates of morbidity and mortality, especially in older mice. No children seem to be dying in China, consistent with them being excluded from a large-scale initial Phase II or Phase III trial. Mortality appears highest in Hubei and Wuhan as well. We know a Phase I trial against SARS was conducted with 120 people by Sinovac around 2007.
Another possibility is that a vaccine used by the Chinese has weakened their response to an otherwise mild coronavirus infection. SARS 2 binding to ACE2 is weaker. Thimerosal inhibits ERAP1. Vaccination with aluminum hydroxide containing vaccines might induce autoimmunity in the lungs. All of these factors could play a role in making vaccinated individuals more susceptible.
A third possibility is that people in that geographic region who had prior SARS infections might be less able to fight off SARS 2 simply due to original antigenic sin from infection. Toronto, Canada, take note.
