ABSTRACT

Neonatal immunotherapy is rapidly emerging as a transformative approach to reducing the high burden of infectious diseases and immune-mediated conditions in early life. Due to the immaturity of the neonatal immune system—characterized by reduced antigen presentation, lower cytokine production, and limited immunological memory—designing interventions that are both safe and effective poses unique challenges. This review provides a comprehensive analysis of current and emerging immunotherapeutic strategies tailored for neonates, including passive immunity through monoclonal antibodies and IVIG, next-generation vaccines utilizing mRNA and novel adjuvants, microbiota-based interventions to restore immune-microbial balance, and nanotechnology-enabled delivery systems for precise targeting. Special attention is given to the complexities of ensuring safety in this vulnerable population, including risks of immune overactivation, developmental interference, and ethical concerns in clinical research. Regulatory hurdles and the need for age-specific formulations further complicate clinical translation. Advances in systems biology and omics technologies are enabling personalized approaches to neonatal immunotherapy by identifying immune signatures and predictive biomarkers. Looking ahead, the integration of immunological insights, ethical frameworks, and technological innovations will be essential to optimize and implement effective neonatal immunotherapies. Future strategies must prioritize both individual patient needs and global equity to ensure that these innovations benefit all neonates, particularly those most at risk.
