COVID-19 Vaccine Related Painless Reactive Thyroiditis - Abstract
In the second year of the SARS-COV-2 global pandemic, there have been many vaccines that has been produced all around the globe. Despite it being safe to be administered, its side effect profile is not fully understood yet. This report aims to document a case of symptomatic hyperthyroidism developing three days after first dose of the Pfizer-BioNTech vaccine. With undetectable TSH, high free T3 and T4, negative thyroid antibodies and thyroid stimulating immunoglobulins, and zero uptake on his thyroid uptake scan, this is consistent with painless reactive thyroiditis, likely vaccine-related due to the time frame.
