This retrospective cohort study of 10,145 pregnant women noted seasonal influenza vaccine coverage increased from 38% to 63% between the 2008–2009 and 2010–2011 seasons and then dropped to 61% in 2011–2012. Vaccine coverage was higher in women considered at high risk of influenza complications, increasing from 43% in 2008–2009 to 71% in 2010–2011, before decreasing to 69% in 2011–2012. H1N1 vaccine coverage was greater than seasonal influenza coverage. The authors observed statistically significant differences in vaccination rates by trimester, gravidity, maternal age, and race/ethnicity
