Abstract

Objectives: 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 coverage among women who delivered a live-born infant during the 2009–2010 influenza season, when two separate influenza vaccinations were recommended. Methods: Pregnancy Risk Assessment Monitoring System (PRAMS) data from 29 states and New York City, collected during the 2009–2010 influenza season, were used to examine uptake of seasonal (unweighted n =27, 153) and pandemic influenza A(H1N1)pdm09 (pH1N1) ( n =27, 372) vaccination by racially/ethnically diverse women who delivered a live-born infant from September 1, 2009, through May 31, 2010. Results: PRAMS data showed variation in seasonal and pH1N1 influenza vaccination coverage among women with live-born infants by racial/ethnic group. For seasonal influenza vaccination, coverage was 50.5% for non-Hispanic white, 30.2% for non-Hispanic black, 42.1% for Hispanic, and 48.2% for non-Hispanic other women. For pH1N1, vaccination coverage was 41.4% for non-Hispanic white, 25.5% for non-Hispanic black, 41.1% for Hispanic, and 43.3% for non-Hispanic other women. Compared with non-Hispanic white women, non-Hispanic black women had lower seasonal (crude prevalence ratio [cPR] = 0.60, 95% confidence interval [CI] 0.55, 0.64) and pH1N1 (cPR=0.62, 95% CI 0.57, 0.67) vaccination coverage; these disparities diminished but remained after adjusting for provider recommendation or offer for influenza vaccination, insurance status, and demographic factors (seasonal vaccine: adjusted PR [aPR] = 0.80, 95% CI 0.74, 0.86; and pH1N1 vaccine: aPR=0.75, 95% CI 0.68, 0.82). Conclusion: To reduce disparities in influenza vaccination uptake by pregnant women, targeted efforts toward providers and interventions focusing on pregnant and postpartum women may be needed.
