In 2005, this was released in "Virology Journal": "Chloroquine is a potent inhibitor of SARS coronavirus infection and spread" - How many lives could have been saved if that hadn't been covered up? This is the article from 14.5 years ago:            https://virologyj.biomedcentral.com/articles/10.1186/1743-422X-2-69 and as a pdf: https://virologyj.biomedcentral.com/track/pdf/10.1186/1743-422X-2-69 (for spreading it via mail etc.) A copy is on: https://www.researchgate.net/publication/7646092_Chloroquine_is_a_potent_inhibitor_of_SARS_coronavirus_infection_and_spread Chloroquine is C18H26ClN3 Hydroxychloroquine is C18H26ClN3O         Both are used for "CoVid-19" (pneumonia) treatment (best with additional zinc) after President Trump recommended it.      So that treatment has been known long before. Who (or better "WHO"?) is responsible for all the deaths from that kind of pneumonia since then? This is the famous 2020 french study (in english): https://www.mediterranee-infection.com/wp-content/uploads/2020/03/Hydroxychloroquine_final_DOI_IJAA.pdf and an earlier version: https://www.mediterranee-infection.com/wp-content/uploads/2020/03/COVID-IHU-2-1.pdf with nearly 100% success after a few days. Another very good info source is Jon Rappaport's blog: https://blog.nomorefakenews.com/ and his informative 3 part audio series (downloadable as mp3): https://home.solari.com/the-creation-of-a-false-epidemic-with-jon-rappoport/ Edit: Thanks to @MolochHunter  for linking from a thread where a much earlier publication is mentioned.  It's from 1982, published in 1983:     "Mechanism of uncoating of influenza B virus in MDCK cells: action of chloroquine." And here the publication as a pdf.
