We compared influenza and pertussis vaccination reporting on the New South Wales (NSW) Perinatal Data Collection (PDC) and the Australian Immunisation Register (AIR) to understand coverage, reporting, timing of vaccination and provider type.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective population-based cohort study in NSW, Australia, included people giving birth at \u226520 weeks gestation (2017\u20132022) on the NSW PDC (total number of pregnancies 555,553), linked to AIR-reported influenza and pertussis vaccinations. The main outcomes of interest were influenza and pertussis coverage according to: (1) the PDC; and (2) linked AIR records. We assessed agreement between data sources (i.e. whether an AIR record during the pregnancy existed if vaccine receipt was reported on the PDC, and vice versa) by year (influenza: 2021\u20132022, pertussis: 2017\u20132022) and selected characteristics (2022). Provider type and timing for vaccinations reported to the AIR are described (2022).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>PDC-reported influenza and pertussis coverage peaked in 2020 (influenza: 58.8%, pertussis: 79.0%), decreasing thereafter (influenza: 49.1%, pertussis: 77.6% in 2022). AIR-reported influenza and pertussis vaccination coverage increased (influenza: 34.7% in 2021 to 44.8% in 2022; pertussis: 24.4% in 2017 to 51.6% in 2022). Agreement between the AIR and PDC improved over time but remained suboptimal (influenza: 75.5%, pertussis: 56.6% in 2022). AIR and PDC agreement differed most by antenatal care model, particularly for pertussis vaccinations. In 2022, of pregnancy vaccinations reported to the AIR, &amp;gt;75% were provided in general practices. Co-administration occurred infrequently (8.8%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Despite mandated reporting to the AIR, there was significant underreporting of pregnancy vaccinations to the AIR when compared with the NSW PDC. National collection of accurate and timely data on pregnancy vaccination coverage is needed to monitor vaccine uptake, and identify and monitor strategies to improve uptake, particularly with the new pregnancy respiratory syncytial virus vaccine program in 2025. We identified co-administration as a potential strategy to improve influenza vaccination coverage during pregnancy.<\/jats:p>\n
