Our objectives were to estimate 2009 pandemic influenza A (pH1N1) vaccination coverage among pregnant women and identify associated factors.
We distributed a multimodal survey to 5341 women who gave birth between November 1, 2009, and January 31, 2010, identified by hospitals in King County, Washington State, with maternity services (n = 11).
Of 4205 respondents, 3233 (76.9%) reported that they had received pH1N1 vaccine during pregnancy or within 2 weeks after delivery. Women whose prenatal care provider recommended vaccine had a higher vaccination prevalence than women whose provider did not (81.5% vs 29.6%; adjusted prevalence ratio = 2.1; 95% confidence interval = 1.72, 2.58). Vaccination prevalence was lower among women who had received prenatal care from a midwife only compared with women who had received care from other providers (62.9% vs 78.8%; adjusted prevalence ratio = 0.89; 95% confidence interval = 0.83, 0.96).
Among pregnant women in King County, pH1N1 vaccination coverage was high. To improve coverage during nonpandemic seasons, influenza vaccine should be recommended routinely by prenatal care providers and vaccination provided where prenatal care is received. Barriers to midwives providing vaccination recommendations to patients should be explored.
我们的目的是评估 2009 年甲型 H1N1 流感大流行期间孕妇的疫苗接种率，并确定相关因素。
我们向华盛顿州金县的 5341 名产妇分发了多模式调查，这些产妇是在 2009 年 11 月 1 日至 2010 年 1 月 31 日期间分娩的，并通过医院确定（n=11）。
在 4205 名应答者中，有 3233 名（76.9%）报告在怀孕期间或分娩后 2 周内接种了 pH1N1 疫苗。与未推荐疫苗的提供者相比，其产前护理提供者推荐疫苗的女性接种疫苗的流行率更高（81.5%比 29.6%；调整后流行率比=2.1；95%置信区间=1.72，2.58）。与从其他提供者那里获得护理的女性相比，仅从助产士那里获得护理的女性的疫苗接种率较低（62.9%比 78.8%；调整后流行率比=0.89；95%置信区间=0.83，0.96）。
在金县的孕妇中，pH1N1 疫苗接种率很高。为了在非大流行季节提高覆盖率，产前护理提供者应常规推荐流感疫苗，并在提供产前护理的地方接种疫苗。应探讨阻碍助产士向患者提供疫苗接种建议的障碍。
