Influenza vaccination during pregnancy is considered safe and effective in preventing serious maternal complications and adverse birth outcomes associated with influenza infection. However, limited research exists regarding the long\u2010term impact of maternal influenza vaccination on offspring neurodevelopment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective cohort study of all singleton\u2010live births among members of Clalit Health Services (CHS), Israel's largest healthcare provider, between January 2016 and December 2020, with follow\u2010up through May 2024. Offspring with developmental disorders of known genetic etiology were excluded. Maternal influenza vaccination during pregnancy (exposure) and offspring ASD diagnosis (outcome) were identified via CHS electronic medical records. The association between exposure and outcome was assessed using Cox proportional hazards models, adjusting for sociodemographic, maternal, and gestational covariates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 153,321 children included in the analysis, 39,361 (25.7%) were exposed to maternal influenza vaccination during pregnancy. The cumulative incidence of ASD was 3.6% for offspring of vaccinated mothers and 2.9% for offspring of unvaccinated mothers resulting in a modestly increased hazard ratio (HR) of ASD associated with influenza vaccination during pregnancy (HR\u00a0=\u00a01.22, 95% CI: 1.14\u20131.31). However, this association was no longer evident after adjustment for sociodemographic and clinical covariates (aHR\u00a0=\u00a00.97, 95% CI: 0.91\u20131.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Maternal influenza vaccination during pregnancy was not associated with an increased risk of ASD in offspring. These results provide valuable confirmation of similar findings from earlier studies, thus further support the long\u2010term safety of maternal influenza vaccination as a preventive healthcare
