## Abstract

Chronic hepatitis B (CHB) remains a significant global health issue, particularly in children, where the virus can lead to long-term hepatic damage and immune system dysregulation. Interferon (IFN) therapy, such as pegylated interferon (PEG-IFN), has served as a fundamental approach in the management of CHB by facilitating immune modulation and viral suppression. Nevertheless, the application of this treatment in children presents unique challenges, including heterogeneous immune responses, potential adverse effects, and constraints regarding long-term efficacy. This perspective discusses the immunological mechanisms associated with IFN therapy in pediatric CHB, emphasizing its potential to enhance immune-mediated clearance and suppress viral activity. We additionally examine the primary clinical challenges, including treatment resistance, adverse effects, and the necessity for personalized approaches to optimize therapeutic outcomes. Furthermore, this study examines prospective developments in IFN therapy, encompassing innovations in drug formulations, combination treatment strategies, and the implementation of personalized medicine approaches. Despite the challenges associated with IFN therapy, it continues to be a promising treatment modality. Furthermore, ongoing research into its combination with other immunomodulatory agents holds potential for developing more effective and sustainable management strategies for children with CHB.
