Adverse Events Following COVID-19 Vaccination

COVID-19 Vaccine adverse events is a challenging topic because they are so numerous and of broad variety.

Research shows that the treatment arm of Covid 19 vaccine trials had significantly more adverse events than the placebo arm.1) Several databases are tracking adverse events resulting from the widespread public roll out of these vaccines.

Adverse Events Following COVID-19 Vaccination (by ICD-10 Organization)

COVID-19 Vaccine Associated Auto-Immune Disorders


  • New-Onset Systemic Lupus Erythematosus after mRNA SARS-CoV-2 Vaccination2)

COVID-19 Vaccine Associated Cardiac Injuries

  • Increased emergency cardiovascular events among under-40 population in Israel during vaccine rollout and third COVID-19 wave3)

Myopericarditis is characterized as inflammation of the pericardium, the membrane surrounding the hear, with involvement of the myocardium. Symptoms include chest pain, fever, and shortness of breath, and are similar to pericarditis. Involvement of the myocardium is diagnosed though testing for elevated troponin through cardiac imaging.

COVID-19 Vaccine Associated Blood and Vascular Disorders


See also: Covid-19 Vaccine Associated Thrombosis

There are three categories of causes of thrombosis: damage to the blood vessel (catheter or surgery), slowed blood flow (immobility), and/or thrombophilia (if the blood itself is more likely to clot).


Hemorrhage (Acral and Reticular)


Cerebral Venous Thrombosis

See also: Covid-19 Vaccine Associated Cerebral Venous Thrombosis

Cerebral Venous Thrombosis is a type of stroke in which the venous channels of the brain become thrombosed, resulting in cerebral infarction in the areas corresponding to the thrombosis.

Intracerebral Hemorrhage

Vasculitis, including Microscopic Polyangiitis

See also: Covid-19 Vaccine Associated Vasculitis

Vasculitis is an inflammation of the blood vessels that causes changes in the blood vessel walls. When your blood vessel becomes weak, it might stretch and bulge (called an aneurysm). It might also burst open, causing bleeding. This can be life-threatening.

Microscopic polyangiitis (MPA) is a a rare type of vasculitis, causing inflammation of the small blood vessels. The disease can damage the blood vessels, nervous system and organs. The FIVE most common clinical manifestations of MPA are: kidney inflammation, weight loss, skin lesions, nerve damage, and fevers.

COVID-19 Vaccine Associated Disorders of the Immune System


See also: Covid-19 Vaccine Associated Anaphylaxis

Anaphylaxis is a severe life-threatening allergic reaction, resulting from the immune system's response to a substance.

Allergic Reactions (other than and including Anaphylaxis)

Covid-19 Vaccine Associated Allergic Reactions

While anaphylaxis is a severe allergic reaction, other allergies can result from or be exasperated by vaccination.


See also: CoVid-19 Vaccine Associated Lymphadenopathy

Lymphadenopathy is swelling of the lymph nodes. These swollen nodes can feel like hard nodules that are sometimes painful and are found in the underarm, groin, neck, chest, and abdomen. The lymph nodes filter lymph fluid as it circulates through the body.

Axillary Adenopathy

Axillary adenopathy is a lymphadenopathy of the axilla, or underarm.

COVID-19 Vaccine Associated Infectious Disease

Herpes Zoster

In a study published in late 2021, researchers found reactivation of herpes zoster among 1.2% of patients receiving BNT162b2 mRNA injections among those with autoimmune inflammatory rheumatic diseases (AIIRD), but none among the 99 patients without AIIRD.4) The control group may be too small for a good comparison.

COVID-19 Vaccine Associated Previously Rare Diseases

Eosinophilic Granulomatosis with Polyangiitis

Eosinophilic granulomatosis with polyangiitis (EGPA) has been associated with CoVid Vaccination. EGPA (formerly Churg-Strauss Syndrome) is an extremely rare disease caused by inflammation of blood and/or tissue cells, which previously was known to effect only two to five new people a year per one million people. Candy Palater, star of Trailer Park Boys, died after being hospitalized and diagnosed with eosinophilic granulomatosis with polyangiitis.

COVID-19 Vaccine Associated Neurodegenerative Disease

Sixteen cases of Creutzfeldt-Jakob disease were reported by researches among those who received COVID-19 vaccination.5)

Jiang, H.; Mei, Y.-F. SARS–CoV–2 Spike Impairs DNA Damage Repair and Inhibits V(D)J Recombination In Vitro. Viruses 2021, 13, 2056. Authors note, “Our findings provide evidence of the spike protein hijacking the DNA damage repair machinery and adaptive immune machinery in vitro. We propose a potential mechanism by which spike proteins may impair adaptive immunity by inhibiting DNA damage repair.”

The Nocebo Hypothesis

In an meta-analysis published by the Journal of the American Medical Association, researchers suggested that a substantial portion of COVID-19 vaccine associated AEs are the result of the nocebo effect.11)

  • Fundamentally, this suggests that those who volunteered as test subjects for vaccine research were people with expectations that the vaccines would harm them. If true, the implications about the relationship between pharmaceutical corporations and their patients is profoundly disturbing. It also suggests a lack of agency among those participating in vaccine testing experiments. None of this is taken into account by the researchers.
  • The meta-analysis failed to analyze the effect of unblinding of the vaccine trials.
  • The meta-analysis failed to observe the large proportion of suspected, but untested and undiagnosed cases of COVID-19 in some of the studies.
  • The author took funding from the German Academic Exchange Service, which seems to promote Orwellian scientific relationships as indicated by their verbose statements that look to be aimed at cooperation with Chinese communist authorities.12)

Hot Lots Hypothesis

Some researchers worry that a small number of vaccine lots or batches are harming large numbers of people.
