Perhaps you will answer this question that I have posed since May across multiple forums--while we await proven vaccines for Covid (which Pfizer and Moderna are not becuase they decided not to test for infections unless symptoms were reported)(https://medium.com/illumination/critique-of-phizers-and-moderna-s-efficacy-and-safety-trials-d56a3e80e653), why were we not prescribed an exising ACE2 inhibitor while a new drug were easily manufactured using the best ACE2 receptor blocker, the Spike itself?
