Fast-Tracked Vaccine May Have Catastrophic Consequences In a recent interview with Robert Kennedy Jr., he summarized the history of coronavirus vaccine development, which began after 3 SARS epidemics had broken out, starting in early Y 2002. And 2 of the 3 epidemics were lab-created organisms. Chinese, Americans and Europeans all started working on a coronavirus vaccine and around Y 2012, there were some 30 promising candidates. As explained by Mr. Kennedy, the 4 best vaccine candidates were then given to ferrets, which are the closest analogue to human lung infections.
