"The conventional SARS-CoV-2 vaccine’s ability to provide immunological protection may be significantly impacted by over-vaccination. If this happens, either newly diagnosed COVID-19 cases or people who have already contracted the virus again may have a more severe case of the illness. This concept was proposed after seeing tolerance of both the humoral and cellular immune responses to prolonged booster immunization doses."
In a turn of events characterized by profound irony, an outbreak of the SARS-CoV-2 virus, which causes COVID-19, occurred at the 2023 Epidemic Intelligence Service (EIS) Conference hosted by the U.S. Centers for Disease Control and Prevention (CDC) itself.
"The signal detected for myocarditis or pericarditis is consistent with that reported in peer-reviewed publications demonstrating an elevated risk of myocarditis or pericarditis following mRNA vaccines, especially among younger males aged 12 to 29 years," the researchers noted.
"Our meta-analysis highlights a link between SARS-CoV-2 vaccination and new onset or worsening of inflammatory and autoimmune skin diseases," the study authors write.
One of the potentially serious side effects of COVID-19 vaccination is acute ischemic stroke, according to a publication in Journal of the Neurological Sciences.
However, a recent U.K. community-based population study found that those who have previously been infected with SARS-CoV-2, which causes COVID-19, demonstrate a lower rate of new Omicron BA.4/BA.5 infections compared to those who were vaccinated.
The study discovered that "the overall risk of retinal vascular occlusion in the vaccinated cohort was 2.19 times higher than that in the unvaccinated cohort at 2 years (95% Cl 2.00–2.39)."
