In regards to an 'own goal' by China on the Wuhan epidemic, I have read several papers that all have found animal trials of SARS vaccines are disastrous. The vaccines for virii with the SARS spike protein all cause deadly pneumonias in subjects when the subjects are challenged with the infection.

China nonetheless human trialed SARS vaccines. Unbelievable, but they said they did themselves. If they vaccinated a lot of people in Hubei Province, it really explains well why China is suffering such terrible pathogenicity, but no other country in the world is.
