Pertussis vaccinations in First Nations pregnancies were 20% lower than non\u2010Indigenous pregnancies; dTpa was strongly associated with IIV uptake (risk ratio (RR): 8.60, 95% CI 8.48\u20138.73). This trend was temporally and jurisdictionally consistent. First Nations women were more likely to have had IIV in pregnancy before the introduction of dTpa in the pregnancy program: (RR: 1.48, 95% CI 1.40\u20131.57), but less likely after dTpa implementation (RR: 0.78, 95% CI 0.76\u20130.80).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Inequity in vaccine uptake between First Nations and non\u2010Indigenous pregnancies, and dismal rates of vaccination in pregnancy overall need urgent review, particularly before the next influenza pandemic or pertussis outbreak.
