COVID-19 Vaccination for Endocrine Patients: A Position Statement from the Korean Endocrine Society

Abstract

Since the first outbreak of coronavirus disease 2019 (COVID-19), ongoing efforts have been made to discover an efficacious vaccine against COVID-19 to combat the pandemic. In most countries, both mRNA and DNA vaccines have been administered, and their side effects have also been reported. The clinical course of COVID-19 and the effects of vaccination against COVID-19 are both in-fluenced by patients' health status and involve a systemic physiological response. In view of the systemic function of endocrine hor-mones, endocrine disorders themselves and the therapeutics used to treat them can influence the outcomes of vaccination for COV-ID-19. However, there are very limited data to support the development of clinical guidelines for patients with specific medical backgrounds based on large clinical trials. In the current severe circumstances of the COVID-19 pandemic, position statements made by clinical specialists are essential to provide appropriate recommendations based on both medical evidence and clinical experienc-es. As endocrinologists, we would like to present the medical background of COVID-19 vaccination, as well as precautions to pre -vent the side effects of COVID-19 vaccination in patients with specific endocrine disorders, including adrenal insufficiency, diabetes mellitus, osteoporosis, autoimmune thyroid disease, hypogonadism, and pituitary disorders.
