Subacute thyroiditis: New entity?

In 2021, the scientific community was marked by the introduction of vaccine against COVID-19. This is major step in overcoming the pandemic, but it does not mean that several side effects or precautions are not related to the immunization; however, the current level of statistical evidence concerning potential negative effects is low, as logically expected at this point. We aim to introduce a female case who was confirmed with subacute thyroiditis after COVID-19 vaccination. Prompt recognition of subacute thyroiditis avoids unnecessary investigations, hospitalizations or even exposure to antibiotics as seen in this case. Early intervention with anti-inflammatory medication releases the symptoms. The association with vaccine against COVID-19 might be incidental or not; more evidence is needed but as far as we might think nowadays, the connection is possible, thus the importance of specific awareness.
