Preterm infants had higher uptake than term (96.9% vs 88.7%; p=0.001), and those admitted to the neonatal unit also had higher uptake (93.0% vs 88.4%; p=0.009). In adjusted analyses, maternal age (adjusted OR (aOR) 1.06 per year, 95%\u2009CI 1.03 to 1.09, p&lt;0.001) and preterm birth (aOR 3.08 (95% CI 1.14 to 8.37), p=0.027) were associated with uptake. Uptake varied by maternal ethnicity: 91.5% in white Irish, 53.6% in Irish Traveller (aOR 0.13 (95% CI 0.08 to 0.23)), 79.7% in other white background (aOR 0.39 (95% CI 0.24 to 0.61)), 90.0% in black or black Irish, 98.3% in Asian or Asian Irish and 84.2% in other\/mixed or prefer not to say. Although uptake among white Irish was high, they accounted for the largest absolute number of infants who did not receive nirsevimab, reflecting their predominance in the birth cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>During the first season of Ireland\u2019s Pathfinder RSV pilot programme in the Mid-West region, nearly 90% of newborns received nirsevimab before discharge. Uptake was consistently high across months, indicating effective implementation but lower among infants of Irish Traveller and other white background mothers, highlighting the need for targeted, culturally adaptable equity strategies within a high-uptake programme. These findings may inform national and international policies and offer practical lessons for universal RSV immunisation.<\/jats:p>\n
