While global concern over vaccine-associated alopecia has been gradually increasing, it has also been reported that alopecia, classified as an autoimmune disease, can manifest as an immune-related side-effect caused by vaccinations. However, comprehensive research on vaccine-associated alopecia has been limited. Therefore, we carried out a comprehensive analysis using information from VigiBase (1979–2023) from more than 156 countries, managed by the WHO and the Uppsala Monitoring Centre. Thus, this global pharmacovigilance study of vaccine-associated alopecia, encompassing all age and sex groups, provides international and comprehensive evidence that substantiates the overall real-world impact of vaccines.
