Even the WHO admits the PCR test doesn’t do what it’s purported to do. From Jon Rappoport at lewrockwell.com:
In early 2020, the WHO accepted a PCR test for “SARS-CoV-2” that was designed without having possession of the virus. Yet the test is meant to detect…the missing virus. This is evidence of deep criminal intent. 
But as of December 14, 2020, WHO has made a correction . Thereby blowing its own cover. Why?
Two reasons. Huge numbers of people have caught on to the PCR test scam. And by their correction, WHO paves the way for “declining COVID case numbers”—thereby making it appear the new vaccine is a roaring success. I predicted this development.  
A brief review. The PCR test (a complete fraud for several reasons) is run in “cycles.” Each cycle is a giant magnification of a tiny portion of the swab sample taken from the patient.
As I’ve reported, even Tony Fauci readily asserts that if the PCR is run at 35 cycles or higher, it’s meaningless.  
Every positive result—indicating “infection with the virus”—occurring at 35 cycles or higher is meaningless.
BUT, as I’ve also pointed out, public health agencies recommend running the PCR test at up to 40 cycles. Therefore, labs comply.
Therefore, millions upon millions of PCR tests results, over the last nine months, which indicate “infection,” are a vast lie.
Therefore, the COVID case numbers are a vast lie, and the lockdowns, which are based on those numbers, are absurd, insane, criminal, and predatory.
