The largest-ever global study on the effects of COVID-19 vaccines has found links to increased blood, heart, and neurological-related conditions.
The study, which examined data from 99 million vaccinated individuals, was performed by the Global Vaccine Data Network and published in the journal Vaccine. It found that mRNA vaccines — those made by BioNTech SE, Moderna, and Pfizer — were linked to an increased risk of myocarditis. Viral-vector vaccines like AstraZeneca’s were linked to an increased risk of cerebral venous sinus thrombosis — a type of blood clot in the brain — and an increased risk of the neurological disorder Guillain-Barre syndrome.
Researchers looked for 13 medical conditions considered “adverse events of special interest” among 99 million vaccinated individuals in eight countries, seeking to identify higher-than-expected cases following a COVID-19 vaccine. In addition to the aforementioned conditions, the scientists also discovered a link between mRNA vaccines and an increased risk of pericarditis and increased risks of transverse myelitis (inflammation of the spinal cord) and acute disseminated encephalomyelitis (inflammation and swelling of the brain and spinal cord) after taking viral-vector vaccines.
The new study is the largest and most comprehensive that points to serious health risks associated with COVID-19 vaccines. A study released last year in the journal Nature revealed that mRNA COVID-19 vaccines produce “unintended proteins” that the body attacks, while a study published in January in the Neurochemical Research journal found that the same vaccines resulted in “autism-like” symptoms in neonatal rats. Also in January, a group of German scientists urged the cessation of mRNA COVID-19 vaccines as “the problems of mRNA-based vaccines are becoming increasingly obvious.”
