Background: Studies have demonstrated disparities in influenza vaccination coverage in the United States. Vaccination during pregnancy significantly reduces the risk of influenza illness among pregnant women and their infants up to 6 months of age; however, many women do not get vaccinated. We examined disparities in vaccination uptake by women who delivered a live-born during 2009-2010 when two separate influenza vaccinations were recommended. Methods: Pregnancy Risk Assessment and Monitoring System (PRAMS) data from 29 states and New York City were used to examine seasonal (n=27,153) and influenza A(H1N1) pdm09 (pH1N1) (n=27,372) vaccination uptake by racially/ethnically diverse participants who delivered a live-born infant. To account for PRAMS methodology, analyses were performed using SUDAAN 10.0. Results: PRAMS data show variation in seasonal and pH1N1 influenza vaccination coverage by racial/ethnic group. For seasonal influenza vaccination, coverage was 50.5% for whites, 30.1% for Blacks, 42.1% for Hispanics, and 48.2% for others. For pH1N1, vaccination coverage was 41.1% for whites, 25.5% for blacks, 41.1% for Hispanics, and 43.3% for others. Compared to whites, black women had lower seasonal (crude RR [cRR]=0.60; 95% Confidence Interval (CI) = 0.55-0.64) and pH1N1 (cRR=0.62; CI: 0.57-0.67) vaccination coverage; these disparities remained after adjusting for provider offer or advice for influenza vaccination, insurance status, and demographic factors for seasonal (adjusted RR [aRR]=0.76; CI: 0.71-0.82) and for pH1N1 (aRR=0.70; CI: 0.64-0.77). Conclusions: To reduce disparities in influenza vaccination uptake by pregnant women, targeted efforts towards providers and interventions focusing on structural barriers inhibiting influenza vaccination may be needed.
