Exactly right on how control groups are supposed to work! As just a thought experiment, I wonder what would happen if half of the Pfizer participants were to receive a letter that they had been injected saline. Maybe that would explain some evidence that vaccinated people are getting the virus.
Or maybe the real culprit is the PCR test. In a page explaining a 'debunked' claim, we see that CT counts over 28 are not suitable for genomic sequencing. Are virus still then suitable for replication and infection? Its likely all tests over 28 cycle count were 'false positives' (or possibly asymptomatic at 28-35 range)

Volunteer control group is not science, but neither is what the wizards are doing behind their curtains.
