ABSTRACT
Early-life immunotherapies are increasingly being explored as a preventive and therapeutic strategy to modulate immune development and protect against both infectious and non-communicable diseases. Administered during critical windows of immune plasticity, these interventions—ranging from vaccines and monoclonal antibodies to microbial-derived adjuvants and immune-modulating agents—can exert long-lasting effects on immune competence, disease susceptibility, and overall health trajectories. This review synthesizes emerging and established evidence on the long-term benefits of early-life immunotherapies, highlighting their potential to reshape health outcomes well beyond childhood. By priming the immune system early, these interventions enhance resistance to infections, reduce the incidence and severity of allergic and autoimmune diseases, and improve the effectiveness and durability of future vaccinations. Mechanisms underlying these benefits include epigenetic reprogramming, development of robust immunological memory, trained innate immunity, and interactions with the microbiome. The review also explores the implications for public health strategies, especially in low-resource settings where early-life interventions may yield significant lifelong health gains. As research advances, early immunotherapeutic approaches may become cornerstone strategies in global efforts to promote immune resilience and reduce the burden of chronic disease
