It seems that a lot of the thyroid diseases are linked to the COVID-19 vaccines, according to the latest reports. Check out more details about this below.
Thyroid diseases and COVID vaccination
According to a recent Indian study, COVID-19 vaccinations, particularly in individuals who have experienced hypothyroidism, may be associated with adverse reactions. The researchers from Banaras Hindu University identified 75 instances of thyroid disturbance following COVID-19 vaccinations.
Patients who received vaccinations after recovering from COVID-19 were at a greater risk of post-vaccine adverse reactions, which persisted.
The study focused on vector-based vaccines of AstraZeneca and the Indian biotech company Bharat Biotech’s Covaxin.
However, it should be noted that isolated cases of thyroiditis have been reported in the early stages of COVID-19 vaccinations, mainly after mRNA vaccines.
Dr. Yusuf Saleeby, an internist and functional medicine practitioner at Carolina Holistic Medicine, believes that similar reactions could be expected from both vector-based and mRNA-based COVID-19 vaccines as both stimulate the body to produce the virus’s spike proteins.
“I see hypothyroidism 90 percent of the time” for patients with thyroid problems post-vaccination, Dr. Saleeby said. It has been observed that some individuals initially show symptoms of hyperthyroidism and later develop hypothyroidism.
Dr. Saleeby suggested that the spike protein may interfere with the normal feedback mechanism that regulates hormone production between the thyroid and other endocrine organs, resulting in hormonal disruption.
A study conducted in May 2020 revealed that antibodies produced in response to the spike protein can bind strongly to thyroid proteins, potentially causing autoimmune thyroid damage.
It is also worth noting the fact that a subsequent study conducted in 2021 found that human antibodies created against the spike protein can react with thyroid tissues.
In October, an Israeli study was conducted to compare the incidence of Graves’ disease in over 1,400 healthy people and more than 700 Graves’ disease patients.
The study found that there was no significant link between those who received at least one dose of the COVID-19 vaccine and the incidence of Graves’ disease.
