Now this is really interesting - dealing with coronavirus infections

Check out this paper:

Chloroquine is a potent inhibitor of SARS coronavirus infection and spread
Background
Severe acute respiratory syndrome (SARS) is caused by a newly discovered coronavirus (SARS-CoV). No effective prophylactic or post-exposure therapy is currently available.

Results
We report, however, that chloroquine has strong antiviral effects on SARS-CoV infection of primate cells. These inhibitory effects are observed when the cells are treated with the drug either before or after exposure to the virus, suggesting both prophylactic and therapeutic advantage. In addition to the well-known functions of chloroquine such as elevations of endosomal pH, the drug appears to interfere with terminal glycosylation of the cellular receptor, angiotensin-converting enzyme 2. This may negatively influence the virus-receptor binding and abrogate the infection, with further ramifications by the elevation of vesicular pH, resulting in the inhibition of infection and spread of SARS CoV at clinically admissible concentrations.

Conclusion
Chloroquine is effective in preventing the spread of SARS CoV in cell culture. Favorable inhibition of virus spread was observed when the cells were either treated with chloroquine prior to or after SARS CoV infection. In addition, the indirect immunofluorescence assay described herein represents a simple and rapid method for screening SARS-CoV antiviral compounds.

Looks pretty cut and dried - a lot more at the site. The numbers are really plain and clear - the stuff works.

What is interesting is that this paper was published on August 22nd, 2005 by the National Institutes of Health. That would be Dr. Fauci's stomping ground. He knew and yet he promoted the development of a new vaccine instead of this simple, cheap, known and effective cure. Dr. Fauci let tens of thousands of people die all so he could promote the expensive vaccine development.

I am most definitely not anti-vax - the common and known ones: Smallpox, MMR, Polio, etc... are life saving and need to be given. What Gates, Fauci, et. al. are doing is unconscionable though. Big difference...
