First came the Chloroquine and Hydroxychloroquine suppression
In 2020, I compiled a list of over 50 ways authorities and pharma companies in multiple countries stopped the use of the chloroquine drugs for COVID. This was (and is) a stunning collection, which has been widely read and reproduced on many websites. When you read it, you are astounded to learn that all the US (and many international) public health agencies took many different actions to increase deaths and destruction from COVID and prolong the pandemic. "Avoiding the Trump drug" served as a great cover story. Taking hydroxychloroquine for COVID was equated to drinking bleach.
But here's the kicker: the authorities knew all about chloroquine and other treatments for COVID before there was a COVID... because they had figured it out for the 2003 SARS epidemic and the 2012 MERS epidemic, both caused by related coronaviruses. But they hushed it up.
Five CDC (US government) scientists published a paper, along with three Canadian government scientists, showing that chloroquine was an effective drug against SARS coronaviruses, in 2005. European scientists had shown the same thing in 2004.
Here is the CDC paper.
