There has been a flood of anecdotal reports on social media of thyroid dysfunction and new thyroid diseases following COVID-19 mRNA vaccination, for both Pfizer and Moderna.

A new Japanese study by Morita et al., of 70 healthcare workers showed increased thyroid auto-antibodies following 2 Pfizer jabs as well as booster shot (click here).

These effects were long-lasting (> 32 weeks). The increase of thyroid auto-antibodies (TRAb) after 2 jabs and after booster jab can be seen in the graph below:

The authors conclude:

“SARS-CoV-2 BNT162b2 (Pfizer) vaccine not only disrupted the steady state of Graves’ Disease, but also newly induced the disruption of thyroid autoimmunity. These findings support previous cases and series that showed the relapse or even new onset of Graves’ Disease potentially associated with the SARS-CoV-2 BNT162b2 mRNA vaccine.”

Types of thyroid dysfunction post mRNA vaccination:

COVID-19 mRNA vaccines can significantly worsen thyroid function (increase or decrease it). These effects are usually permanent, resulting in a need for medication for life. Symptoms usually appear in 10-15 days following mRNA vaccination.

Subacute thyroiditis – thyroid inflammation, mostly in women (click here). Seems to be the most common thyroid disease reported after mRNA vaccination, with symptoms developing on average 10 days after 1st or 2nd dose. Treated with NSAIDs or steroids (click here).

Graves Disease is the most commonly reported autoimmune thyroid disease post mRNA vaccination which can cause new onset Graves’ disease or a relapse of Graves’ Disease hyperthyroidism (click here), also about 10 to 15 days after 1st or 2nd jab.

Hashimoto’s Disease (decreased function) is also starting to show up (click here)

Thyroid storm – a severe case of thyroid inflammation requiring hospitalization has been reported in the literature (click here).

Thyroid cancer – these are most concerning stories of all. People develop strange lumps in the neck following mRNA vaccination and sometimes these turn out to be malignant.

My Take…

This is yet more evidence of immune system damage and dysfunction following COVID-19 mRNA vaccination.

This new Japanese study of 70 healthcare workers shows an increase of thyroid auto-antibodies after every Pfizer mRNA dose. The authors suggest it may be due to “molecular mimicry of the SARS-CoV-2 mRNA vaccines encoding proteins that may cross-react with thyroid antigens”, which results in auto-antibodies being produced against your thyroid gland.

Thyroid problems following mRNA vaccination seem to be increasing in frequency and anyone experiencing unusual symptoms in the first few weeks after mRNA vaccination, should have their thyroid function checked by their doctor.
