Influence of COVID-19 vaccines on endocrine system

The COVID-19 pandemic has posed a significant health threat globally. Timely and appropriate vaccination is a key step to reduce the morbidity and mortality from COVID-19. The clinical course of COVID-19 infection and the effects of COVID-19 vaccination are influenced by patients’ health situations and involve a systemic physiological reaction. Just like an “endocrine phenotype” of COVID-19 infection, endocrine dysfunction after COVID-19 vaccination also acquired clinical concerns. In the present review, we briefly introduce the commonly available vaccines against SARS-CoV-2, summarize the influence of COVID-19 vaccines on the endocrine system, and explore the underlying pathogenic mechanisms.
