“This 2012 research study would suggest the elites knew of Coronavirus Vaccine Induced Immunopathology....”
Yes, there were several dead ends, in earlier technical approaches to coronavirus vaccines. Whole virus approaches have been abandoned everywhere because of the potentially (frequently) fatal side effects (immune over-reaction), upon later challenge by the disease.
Toward the end of the article (Table 2. Summary of Reported Protection and Immunopathology in Animal Model Studies with SARS Coronavirus Vaccines.) you can see that several technical approaches were identified that caused this serious immune over-reaction - but two types using the spike protein did not.
None of the Operation Warp Speed candidates used the technical approaches that such earlier research has ruled out (such as whole virus approaches).
Knowing that immune over-reaction to future challenge had been a problem with coronavirus vaccines (ADE, cytokine storm), that was a particular area of testing for the currently authorized vaccines. They did not have the effect described for these earlier failed approaches.
