 The study found that vaccinating premature and low birth weight, LBW, infants according to chronological age is safe and effective, but often delayed. Vaccination coverage in preterm and LBW infants compared to term infants was evaluated using the National Immunization Registry in a cohort study of 181,543 births in Israel. Preterm infants comprised 7% of the cohort, while LBW infants were 7.7%. Compared to normal birth weight, NBW, infants, LBW infants showed delayed initiation of vaccinations for DTAR-PIPV-HIB and ROTA. At 24 months, there was no significant difference regarding vaccination status. The study highlights the need for health practitioners and parents to cooperate to improve timely vaccination initiation in preterm and LBW infants.
