Neonatal infectious diseases remain an important cause of early-life morbidity and mortality. In Uzbekistan, improvements in maternal and child healthcare have enhanced neonatal survival; however, conditions such as neonatal sepsis, hepatitis B vertical transmission, and tuberculosis exposure continue to pose challenges. Early vaccination, administered at birth or during the first weeks of life, is a key preventive strategy. This review analyzes national epidemiological data from 2022 to 2024 to evaluate the impact of early immunization on neonatal infectious disease incidence in Uzbekistan. The study focuses on BCG vaccination, hepatitis B birth-dose coverage, and maternal tetanus immunization. The findings show a consistent decline in neonatal infectious disease rates over the three-year period, alongside vaccination coverage levels exceeding 95%. Reductions in perinatal hepatitis B transmission and sustained elimination of neonatal tetanus highlight the effectiveness of timely immunization and strengthened perinatal care. Overall, early vaccination remains a cornerstone of neonatal infection prevention in Uzbekistan, contributing significantly to improved health outcomes and reduced infectious morbidity.
