"I would note that Wuhan has China's only biosafety level-four super laboratory that works with the world's most deadly pathogens to include, yes, coronavirus,"
Some scientists now speculate that the government of the PRC was using this lab to devise a biowarfare pathogen. The process would include developing a vaccine, then testing the vaccine. The test subjects would likely be human. China, with the assistance of other communist countries, has a history of experimentation on human subjects, e.g. Korean War POWs.
The possible scenario for the current outbreak is that the test vaccine was ineffective and the human test subjects were not effectively quarantined. There is an historical parallel concerning the Spanish Flu outbreak. It has been alleged that the Spanish Flu of 1918 was the result of contaminated Yellow Fever vaccines. If a bioweapon development proves to be the cause, then it is likely that this pathogen will not be contained effectively, at least not in China. The measures that the PRC has taken so far seem too little too late. Leaked video of doctors having meltdowns as the hospitals are overwhelmed seem to confirm that the situation is out of control.
