Subacute thyroiditis after COVID-19 vaccination

The Society's Clinical Committee request your help to gather data on the occurrence of subacute thyroiditis after COVID-19 vaccination.

Dr William Bennet and colleagues in Sheffield have had a case of subacute thyroiditis develop shortly after viral vector DNA COVID-19 vaccination (Oxford-AZ), and there is a literature report of it occurring following mRNA COVID-19 vaccination. They want to find out your experience of this, to determine if this is a relatively common occurrence that endocrinologists must remain vigilant for.

Submit your responses to the questions below to clinical@endocrinology.org by Friday 18 June

1. Have you seen a case of subacute thyroiditis which developed within 28 days of COVID-19 vaccination? If yes, how many cases?
2. Which vaccine was used? Oxford–AstraZeneca/Pfizer/BioNTech/Moderna/Other
