Single Dose of Covid Vaccine Linked to Autoimmune Disorders in Thyroid

Study Finds Correlation Between Covid Vaccination and Thyroid Disorders

A recent peer-reviewed study has found a connection between the Covid vaccination and the onset of two new thyroid disorders, Graves’ disease (GD) and Subacute thyroiditis (SAT). The researchers, however, are yet to determine if these vaccine-induced conditions are similar to their non-vaccine-induced counterparts. The study, published this month, states, "GD and SAT have been reported as primary hyperthyroidism etiologies after the mRNA (SARS-CoV-2) vaccine injection. However, whether these two thyroid diseases induced by the mRNA COVID-19 vaccine have the same course and features is unclear."

Research Methodology

In order to reach their conclusions, the researchers examined numerous medical databases for instances of patients developing these disorders following mRNA injections. "We searched multiple databases, including Medline, Web of Science, Cochrane Library, PubMed, Embase, and conference proceedings from inception to November 2023, for articles reporting GD and SAT following the COVID-19 mRNA vaccine (Pfizer and Moderna)," the study explained.

Findings of the Study

The study found 77 cases of individuals who developed thyroid-related diseases (38 cases of Graves’ disease and 39 cases of subacute thyroiditis) after receiving the Covid vaccine. The rate of autoimmune disease onset post-vaccination was higher in women, with a 2 to 1 ratio compared to men. While the risk of developing thyroid-related autoimmune disorders post-vaccination is rare, the researchers noted it as significant, especially considering these patients did not have autoimmune diseases prior to vaccination. The study also found that the rate of thyroid disorder onset was highest after the first injection, with subsequent injections resulting in a lower risk of autoimmune disorders. This is in contrast to overall lethality, which increases with more doses.

Previous Studies on Covid Vaccines and Autoimmune Diseases

Previous research has also suggested that the gene-therapy Covid injections could potentially cause autoimmune diseases. "A growing number of reports have documented associations between COVID-19 vaccination and autoimmunity, suggesting, for example, a causal link between vaccination and new-onset and/or relapsing autoimmune disorders such as type 1 diabetes mellitus, rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosus, Graves disease, and Hashimoto’s thyroiditis," the study stated. Despite these findings, the CDC continues to recommend that all Americans receive their Covid shot, and that young children receive an additional dose.

Conclusion

This study brings to light the potential risks associated with the Covid vaccine, particularly in relation to autoimmune disorders in the thyroid. While the risk is considered rare, it is significant, especially for those who did not have autoimmune diseases prior to vaccination. It raises important questions about the safety and potential side effects of the vaccine. What are your thoughts on this?
