Novel pandemic A (H1N1) influenza vaccination among pregnant women: motivators and barriers.

We sought to examine motivators and barriers related to monovalent 2009 influenza A (H1N1) vaccination among pregnant women. We conducted a national poll of pregnant women using a random online sample (237) and opt-in supplement (277). In all, 42% of pregnant women reported getting the vaccine. Vaccination was positively associated with attitudinal factors including believing the vaccine is very safe or benefits the baby, and with provider recommendations. Women in racial/ethnic minority groups, women with less education, and women <35 years were less likely to get the vaccine and had differing views and experiences. Despite H1N1 vaccination rates that are higher than past seasonal influenza rates, barriers like safety concerns may persist in a pandemic. Messaging from providers that encourages women to believe the vaccine is very safe and benefits their baby may be compelling. Messaging and outreach during future pandemics may require customization to increase vaccination among high-risk groups.

Uptake of influenza vaccine in pregnant women during the 2009 H1N1 influenza pandemic.

The goals of this study were to define the uptake of H1N1 and seasonal influenza vaccination during pregnancy among women delivering during the 2009 H1N1 pandemic and explore barriers to vaccination. All postpartum women at the Massachusetts General Hospital from January 2010 through March 2010 were invited to complete an anonymous questionnaire about demographics, vaccination status, and attitudes about vaccination during pregnancy. Among 370 participants (53% response rate), 81% accepted both the H1N1 and seasonal influenza vaccines during pregnancy. Patients who declined one or both vaccines cited concerns over safety as a major deterrent. Of the 36% of participants who reported having flu-like symptoms during this pregnancy only 8.6% took oseltamivir. While a high vaccination rate was identified in this study, further education is needed to reassure patients regarding vaccine safety. Education for providers and patients emphasizing the benefits of early treatment of pregnant women with flu-like symptoms should be a priority.

Influenza vaccination coverage among pregnant women--National 2009 H1N1 Flu Survey (NHFS).

We sought to describe vaccination with influenza A (H1N1) 2009 monovalent (2009 H1N1) and trivalent seasonal (seasonal) vaccines among pregnant women during the 2009 through 2010 influenza season. A national H1N1 flu survey was conducted April through June 2010. The 2009 H1N1 and seasonal vaccination coverage estimates were 45.7% and 32.1%, respectively, among pregnant women aged 18-49 years. Receipt of a health care provider's recommendation for vaccination, perceived effectiveness of influenza vaccinations, and perceived high chance of influenza infection were independently associated with higher 2009 H1N1 and seasonal vaccination coverage. Pregnancy during October 2009 through January 2010 was independently associated with higher 2009 H1N1 vaccination coverage. The 2009 H1N1 vaccination level among pregnant women was higher than the seasonal vaccination level during the 2009 through 2010 season; it was also higher than vaccination among nonpregnant women with and without high-risk conditions. Health care providers and public health messaging played important roles in influencing vaccination behavior.

Predictors of H1N1 vaccination in pregnancy.

The purpose of this review was to determine factors that influence a pregnant woman's acceptance of the H1N1 vaccine with the use of the Health Belief Model (HBM). A self-administered questionnaire based on the HBM was used in a cross-sectional study of postpartum women during the 2009 H1N1 epidemic. Overall, 212 postpartum women were approached and agreed to participate; of these women, 25.5% had received an H1N1 vaccination. Perceived barriers to vaccination (P = .001) and perceived severity of infection (P = .018) were independent predictors of vaccination. The total predictive utility of the full model that incorporated HBM dimensions, age, race, care provider, and education level was moderate (area under the curve, -0.86). The addressing of perceived barriers (such as fear of side-effects), an explanation of the safety of the vaccine for the fetus, and the stressing of complications that are associated with H1N1 infection in pregnancy may increase the rate of vaccination.
