Letter to the editor: Exacerbation of autoimmune hepatitis after COVID-19 vaccination.

We read with interest in the autoimmune hepatitis (AIH) case following COVID-19 vaccination (1) and Dr. Mungmunpuntipantip' comment (2). COVID-19 vaccine could also act as a trigger in the disease course of AIH. We report a case of AIH exacerbation following inactivated whole-virion SARS-CoV-2 vaccine (CoronaVac). The patient is a 57-year-old Asian female without medical history. She developed choluria and acholic stools two weeks after 1st-dose CoronaVac but didn't seek medical advice and received 2nd-dose CoronaVac after three weeks.
