Article Synopsis
- A nationwide study was conducted to explore the link between COVID-19 mRNA vaccinations and autoimmune hepatitis (AIH), which had mostly been reported in isolated case reports.* -
- Out of 76 patients diagnosed with acute AIH between January 2019 and February 2023, only 6 women (aged 40+) developed symptoms within 42 days post-vaccination, suggesting a very low incidence.* -
- Both observed-over-expected and self-controlled case series analyses showed no statistically significant increase in AIH cases post-vaccination, indicating that COVID-19 mRNA vaccines don't appear to raise the risk for this condition, though more extensive studies are needed.*
Introduction: Anaphylaxis was the first serious adverse event (AE) of special interest surfaced in Singapore following coronavirus disease 2019 (COVID-19) vaccination. Individuals who developed physician-diagnosed severe allergic reactions to the mRNA vaccines would be medically ineligible for mRNA vaccines and offered non-mRNA alternatives. This paper describes anaphylaxis reports received by the Health Sciences Authority (HSA) and presents a review of individuals who received heterologous COVID-19 vaccination.
