Why was this done? How did it happen?
One of dozens upon dozens by so-called “experts”, and yet, each step along the way there was nothing but arrogant recrimination, jeers, mockery directed at voices crying out SCAM!
And then, silence followed by a repeat of the mudslinging playbook directed at IVM.
The enemy reveals itself by foolishly repeating its duplicity.
Non sequitur.
Apples and oranges. In the case of batch checkers, you have lab workers all over the world physically checking samples from each batch.* In the case of your HCQ study published in the Lancet, the article was pulled because raw data used in the study was not available for peer review.
*And they have caught contaminants in some batches and prevented distribution. People are not perfect, however, and human error happens, which is how a few contaminated batches of Moderna got shipped from Spain to Japan back around August. The contaminants had been flagged by Spanish batch checkers, but a few batches were mistakenly sent to Japan because somebody goofed. When Japanese distributors checked those batches and found the contamination, Japan immediately suspended *all* Moderna vaccines until the issue was sorted and all contaminated vials identified and withdrawn.
