WHO finally admits that PCR tests are unreliable

The World Health Organization has finally admitted in a memo from December 14, that high cycle thresholds on PCR tests for Sars-Cov-2 will result in false positives. The question is: Why only now?

    This explosive information on the unreliability of PCR tests has been available for months. It is therefore curious that the WHO took so long to make such an announcement. Cynics argue that the WHO dragged their feet on purpose, because they wanted to make it appear as though vaccines actually work.

    As FWM reported earlier, the design of the vaccine used false positive PCR results to boost its efficacy rate. Dr. Tommy Megremis had warned on Facebook: “The problem is in the false positivity if you will for the PCR test. If you are generally aware, the PCR test is used to amplify small amount of genetic material so as to recognize patterns of DNA by ‘cycling’. […] It works because if you amplify and cycle enough times to ‘grow’ legitimate DNA fragments, you get something with with a fair amount of specificity.

    “What is becoming more and more apparent is that the PCR test was not designed as a diagnostic tool for infection, and really cannot function as one without having a huge amount of false positives, period. When it comes to Covid, the presence of viral particles picked up by the PCR technique does not and has not been quantitatively linked to an active ‘symptomatic’ infection. It simply cannot be so, because infection threshold as a result of viral load is different for each patient. It turns out, if you ‘cycle’ over around 25 times, the false positivity of Covid infection starts getting very high.”

    The polymerase chain reaction tests (PCR) works by taking nucleotides – tiny fragments of DNA or RNA – and replicating them until they become enough in quantity to eventually identify.

    The replication is done in cycles, with each cycle doubling the amount of genetic material. The number of cycles it takes to produce an identifiable gene is known as the “cycle threshold” or “CT value”. The higher the CT value, the more likely it is to test for the presence of Sars-Cov-2. Despite this, many governments and health officials have been relying on PCR tests to make far-reaching pronouncements.

    According to the WHO: “Users of RT-PCR reagents should read the IFU carefully to determine if manual adjustment of the PCR positivity threshold is necessary to account for any background noise which may lead to a specimen with a high cycle threshold (Ct) value result being interpreted as a positive result.

    “The design principle of RT-PCR means that for patients with high levels of circulating virus (viral load), relatively few cycles will be needed to detect virus and so the Ct value will be low. Conversely, when specimens return a high Ct value, it means that many cycles were required to detect virus. In some circumstances, the distinction between background noise and actual presence of the target virus is difficult to ascertain.”

    Thus, any test with a CT value of over 35 is potentially meaningless. Dr Kary Mullis, the Nobel Prize laureate who invented the PCR process, has been adamant that was never meant as a diagnostic tool. Similarly, the MIQE guidelines for the use of PCR state: “Cq values higher than 40 are suspect because of the implied low efficiency and generally should not be reported.”

    Therefore PCR tests will in future be done “under the new WHO guidelines”, running only 25-30 cycles instead of more than 35. This in turn, will result in the number of “positive Covid cases” plummeting, making it appear as if vaccines work.

    Thus, after months of flooding the Covid data pool with false positives, miscounting deaths “by accident”, or adding “Covid-19 related death” on many death certificates, the WHO is now back-peddling on its claims.

    Recipients of placebo jabs to have same privileges as the fully vaxxed, UK minister says

    LondonThe British Vaccine Deployment Minister Nadhim Zahawi stretched the incredulity of his subjects once again by announcing that people who have received placebo jabs would be regarded as "fully vaccinated". According to Zahawi, fake shots would be considered proof of vaccination status.

    Second French hospital calls unlimited strike against forced vax

    How safe are jabs if vaccinated still get infected and transmit Covid-19?

    The aggressive promotion of Covid vaccine passports and draconian vaccine mandates by globalists are not going as smoothly as they had hoped. Vaccinated people can still get infected and transmit disease, so this clearly eliminates the argument that the unvaccinated bring harm to others. And how safe are the jabs?

    The single most important objective of mass vaccination with Covid-19 vaccines was to achieve herd immunity. This is no longer within reach. Now "experts" not only blame disappointing vaccine coverage rates but also the unvaccinated.

    Incompetence or malice: Navalny case uncovers European bureaucratic inconsistencies

    MoscowA year ago, the topic of the alleged “poisoning” of the Russian oppositional blogger and political activist Alexei Navalny was one of the most discussed in the West. Almost everyone commented: politicians were denouncing the next “crimes” of the Kremlin, while journalists and human rights activists called the incident with Navalny a political reprisal if not a political murder sanctioned personally by Putin.

    AlmeríaSpanish scientists have become aware of graphene oxide being used in Covid vaccines, but their claims have been dismissed by "fact-checkers" as nonsense. However, graphene-based “neuromodulation” technology showing “biocircuits” based on graphene oxide are, in fact, already available.
