From [HERE] A peer-reviewed study of 9.2 million South Koreans published in Nature Communications uncovered a 620% increased risk of myocarditis and 175% higher risk of pericarditis following mRNA COVID-19 vaccination. Researchers also noted increased risks of several autoimmune conditions, especially after booster doses.

A large-scale peer-reviewed South Korean study has found significantly increased risks of serious cardiac and neurological conditions following mRNA COVID-19 vaccination, and lesser risks of several autoimmune diseases.

The nationwide population-based cohort study, published Tuesday in Nature Communications, followed nearly 4.5 million people for an average of 15 months after vaccination.

Researchers found a striking 620% increased risk of myocarditis and 175% increased risk ofpericarditis in people who received the vaccine compared to historical controls.

The study also revealed a 62% increased risk for Guillain-Barré syndrome (GBS), a rare neurological disorder.

The researchers did not highlight the the cardiac and GBS risks, but only used the data to confirm the validity of their study design, which focused on determining the risks of autoimmune diseasesassociated with mRNA COVID-19 vaccines.

The researchers found a 16% increased chance of systemic lupus erythematosus (SLE — the most common lupus type) and a 58% higher risk of bullous pemphigoid (BP — large, fluid-filled blisters).

The study also revealed that booster shots were associated with slightly increased risks of severalautoimmune connective tissue diseases (AI-CTDs), including alopecia areata (patchy hair loss),psoriasis (scaly, inflamed skin) and rheumatoid arthritis.

“Given that the risk of SLE and BP was increased in certain demographic conditions such as age and sex, long-term monitoring is necessary after mRNA vaccination for the development of AI-CTDs,” the study authors noted.

Brian Hooker, Ph.D., chief scientific officer at Children’s Health Defense (CHD), noted how the authors minimized the most alarming data but told The Defender the study was otherwise “very robust.”

Hooker said several other studies also show relationships between autoimmune disorders — including systemic lupus — and mRNA vaccination.

The Nature Communications article follows another South Korean study published in May that found significant increases in the incidence of Alzheimer’s disease and mild cognitive impairment following COVID-19 mRNA vaccination. [MORE]
