What If the COVID Case Numbers Were Wrong?

One of the foundations of the world's response to COVID was the PCR test.

Every evening we watched the number of new "cases". Those numbers drove public fear and helped governments justify lockdowns, border closures, mask mandates, school closures and, eventually, vaccine mandates.

But what if those numbers substantially overstated the number of people actually infected?

A remarkable peer-reviewed German study highlighted recently by Dr John Campbell, titled "PCR Massively Wrong", raises precisely that question.

The German study

The study, published in Frontiers in Epidemiology, analysed PCR and antibody testing data from Germany's ALM consortium of accredited medical laboratories. These laboratories conducted approximately 90% of Germany's SARS-CoV-2 PCR testing during the pandemic.

The researchers compared positive PCR results with subsequent IgG antibody evidence of infection.

Their conclusion was startling.

They estimated that only about 14% — and possibly as few as 10% — of PCR-positive individuals were actually infected, as inferred from the antibody data.

Put another way, their analysis suggests that 86–90% of positive PCR results may not have represented genuine infections as they defined them.

That does not mean researchers have taken individual PCR tests and demonstrated an 86–90% laboratory false-positive rate. The German study uses population-level PCR and antibody data to reach its conclusion, and its assumptions will undoubtedly be challenged.

But even allowing for that qualification, the discrepancy is enormous.

For readers interested in how PCR testing works and the reasoning behind the study, I recommend watching Dr John Campbell's explanation and reading the original peer-reviewed German study.

Why does it matter?

Because PCR-positive "cases" became one of the principal measures by which governments judged the severity of the pandemic.

Rising case numbers were used to justify extraordinary restrictions on normal life.

Businesses were closed. Children were kept out of school. Borders were shut. Families were separated. People were prevented from visiting dying relatives. Governments accumulated enormous debts. Eventually millions of people faced vaccination requirements to work, travel or participate normally in society.

COVID was real, and it undoubtedly killed many people, particularly among the elderly and vulnerable.

But that does not answer a different question:

Was the scale of the threat substantially exaggerated by the way we measured it?

If this German analysis is even approximately correct, that question demands serious investigation.

The COVID story keeps changing

Perhaps the most disturbing legacy of COVID was the insistence that "the science was settled".

It wasn't.

The lab-leak theory moved from being dismissed as a conspiracy theory to a legitimate subject of investigation. Claims about vaccines preventing infection and transmission proved far less durable than originally suggested. Questions about adverse effects continue to emerge. Excess mortality remains a subject of debate.

And now a peer-reviewed study is questioning the reliability of the very "case" numbers that dominated our lives.

This doesn't prove that every pandemic policy was wrong. Nor does one study settle the PCR debate.

But it provides another reason why the COVID years deserve a thorough and independent reassessment.

The COVID story on Grappy's Soap Box

I have followed this evolving story for several years. For readers interested in exploring it further:

The mRNA Story Is Not Finished Yet — Why continuing evidence about the behaviour and persistence of mRNA vaccines deserves investigation.

Pandemic Excess Mortality 2025 — Excess mortality remained elevated years after the pandemic, raising questions that still deserve answers.

On the Grapevine — COVID Archive — A continuing collection of research, reports and videos questioning aspects of the pandemic response, vaccines and excess mortality.

Grapevine 2023 — COVID, Excess Deaths and Origins — Earlier material covering excess deaths, vaccine safety, parliamentary debate and the origins of COVID.

The picture is still incomplete. Some of today's conclusions may themselves be revised as better evidence emerges.

That is how science is supposed to work.

What should never happen again is for legitimate questions to be silenced simply because the answers might be inconvenient.

Five years later, perhaps the most important lesson of COVID is very simple:

Never confuse "the science" with science.
