Post COVID-19 injection syndrome is just “distorted disinformation”


A group called the World Health Council – which includes several COVID-19 conspirators – says coronavirus vaccines are behind a new “complex multisystem inflammatory syndrome” called pCoIS.

However, there is no credible evidence that such a syndrome exists, and experts say the group’s information regarding the alleged syndrome is “a muddled mixture of misinformation.”

The World Health Council page, shared on Facebook by a New Zealand account among others, is presented as a guide to health and side effects following a COVID-19 vaccination.

The page includes an entry for “Post COVID-19 Injection Syndrome”, or pCoIS, also purportedly known as “Post COVID-19 Vaccination Syndrome”. He says that “the syndrome is a set of symptoms that can differ from person to person.”

He goes on to say that “emerging data” shows the syndrome to be “similar to long COVID or chronic fatigue syndrome” before listing a number of symptoms, such as muscle and joint pain and severe fatigue.

Nonetheless, there is no record of a “post COVID-19 injection syndrome” or vaccination syndrome in reputable academic journal aggregators, such as PubMed and the Cochrane Library. The American Center for Disease Control and Prevention (CDC) and World Health Organization The (WHO) websites also do not contain any reference to any of the names of the suspected syndrome.

The website claims that the eight categories of pCoIS included conditions such as Parkinson’s disease, dementia and multiple sclerosis, as well as various cancers. However, none of these are among the rare and serious side effects of COVID-19 vaccinations by reputable health organizations.

The CDC says The rare serious side effects of the vaccination included anaphylaxis, blood clots and myocarditis, but said that “serious side effects that could cause a long-term health problem are extremely unlikely after a vaccination.”

that of New Zealand Ministry of Health website lists headache, chills, fever, nausea, and fatigue as common side effects of Pfizer vaccine, while rare but potentially serious side effects included myocarditis and allergic reactions.

Professor of Medicine at Flinders Nikolai Petrovsky University, who founded the company Vaxine, who developed COVID-19 vaccines among other diseases, says AAP fact check that he had never heard of “post COVID-19 injection syndrome” or pCoIS.

“Obviously, there is no evidence base for claims such as cancer caused by vaccines, so the information appears to be a confusing mix of misinformation,” he said via email.

Three other experts – James Ussher, University of Otago Immunologist, which is part of the New Zealand government COVID-19 Vaccine Technical and Scientific Advisory Group, University of Otago epidemiologist Peter McIntyre, a medical adviser for New Zealand Vaccination advisory center, and Graham Le Gros, Immunologist from Victoria University of Wellington – also says FactCheck AAP they had never heard of pCoIS.

Dr Ussher noted that the website did not contain any references to substantiate its information and that the definition of “pCoIS” was “extremely broad and could encompass anything”.

Professor McIntyre said that while some people experience muscle and joint pain, gastrointestinal upset and fatigue after vaccination, the eight categories of pCoIS are “just tosh.”

Professor Le Gros said the description of pCoIS “would appear to be a complete fabrication of the World Health Council website”.

“There is no database to back up their claims, nor a clinical study or published clinical report to back up the claims,” he said in an email.

The pCoIS therapies listed on the website include ivermectin, which has often been touted as a potential COVID-19 treatment despite the lack of clear evidence of its effectiveness.

The World Health Council page referring to pCoIS is identified as having been reviewed by six physicians. One of them, Mark Trozzi, labeled the COVID-19 vaccines “a dangerous experimental injection for a non-fatal disease”, while others such as Nasseba Kathrada and Pierre Kory are leading advocates of ivermectin as a COVID-19 treatment (see here and here).

The origins of the World Health Council are unclear. The “About” section of its website refers to a launch announcement from September 2021 describing the group as “an umbrella organization led by several frontline health and wellness organizations from around the world.”

Meanwhile, his “steering group” includes the names of various personalities who have promoted unfounded conspiracy theories about COVID-19 vaccines, as well as advocates for ivermectin.

Among them, Anna de Buisseret, who has said COVID-19 vaccinations are biological weapons used as part of a “eugenics program”. Other members include Tess Lawrie, the founder of a ivermectin advocacy group and Zac Cox, a homeopathic dentist.

The verdict

There is no recognized new disease called post COVID-19 injection syndrome, or pCoIS, and there is no evidence that COVID-19 vaccines cause many of the conditions associated with them.

The origin of the term appears to be the World Health Council, an organization that includes several supporters of baseless COVID-19 and anti-vaccination conspiracy theories. Many experts claim that there is no scientific basis for the claims related to the so-called syndrome.

False – The assertion is incorrect.
