“…29,32,33 Interestingly, in our study population we consistently observed the highest coverage rates in Asian/Pacific Islanders during the entire study period, as well as Hispanics during the last 2 influenza seasons. We saw increases in vaccination coverage in all racial and ethnic groups, but we saw the largest increases in blacks (from 32% in 2008-2009 to 60% in 2011-2012) and Hispanics (from 33% to 69%), to the extent that coverage in these ethnic and racial groups is now on par with, or exceeding, coverage in other groups.…”

“…The coverage rates we observed are significantly higher than historic rates but are consistent with more recent reports of vaccine coverage. [26][27][28][29] We found that rates of MIV coverage during the 2009-2010 influenza season were higher than for TIV coverage, suggesting that improved vaccination rates may have been spurred by increased awareness or concern about H1N1 infection, as well as by increased efforts on the part of clinicians and of our managed care organization to increase vaccination rates in this population. 27 Table 4 summarizes a number of strategies our Health Plan has implemented over the past several years to improve influenza vaccination coverage during pregnancy, including patient reminders on after-visit summaries, clinician reminders on prenatal visit checklists, and clinician tools and reminders in the EMR.…”

“…6 Before 2009, vaccination coverage in pregnant women ranged from less than 10% to 33%. 17,26,27 Seasonal vaccination rates have risen dramatically since the 2009 H1N1 pandemic, with recent vaccination coverage rates during pregnancy reported at approximately 50%, [27][28][29] but still fall well below the Healthy People 2020-recommended target of 80% vaccination coverage for pregnant women. 30 The goal of this retrospective cohort study was to compare seasonal trivalent influenza vaccine (TIV) coverage rates in pregnant women during four consecutive influenza seasons (2008-2009, 2009-2010, 2010-2011, 2011-2012), as well as the novel monovalent pandemic H1N1 vaccine (MIV) during the 2009-2010 influenza season.…”

Context: Pregnant women are at increased risk of severe influenza-related complications and hospitalizations and are a priority group for influenza vaccination.Objective: To examine coverage of seasonal and pandemic influenza A (H1N1) vaccines in pregnant women in a managed care setting, from 2008 to 2012.Design: Retrospective cohort study of 10,145 pregnant women. Main Outcome Measures: H1N1 and seasonal influenza vaccination rates.Results: Seasonal influenza vaccine coverage increased from 38% to 63% between the

Pregnancy Dose Tdap and Postpartum Cocooning to Prevent Infant Pertussis: A Decision Analysis

et al. 2013

View full text Add to dashboard Cite

WHAT'S KNOWN ON THIS SUBJECT: Infants aged ,2 months are at highest risk for pertussis morbidity and mortality but are too young to receive pertussis vaccines. To protect young infants, the Advisory Committee on Immunization Practices recommends mothers receive 1 dose of Tdap during pregnancy. WHAT THIS STUDY ADDS:This article evaluates the effect of Tdap during pregnancy compared with postpartum Tdap and cocooning in preventing infant pertussis cases, hospitalizations, and deaths, as well as their relative cost-effectiveness. abstract BACKGROUND: Infants ,2 months of age are at highest risk of pertussis morbidity and mortality. Until recently, the US Advisory Committee on Immunization Practices (ACIP) recommended protecting young infants by "cocooning" or vaccination of postpartum mothers and other close contacts with tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis, adsorbed (Tdap) booster vaccine. ACIP recommends pregnancy vaccination as a preferred and safe alternative to postpartum vaccination. The ACIP cocooning recommendation has not changed. METHODS:We used a cohort model reflecting US 2009 births and the diphtheria-tetanus-acellular pertussis schedule to simulate a decision and cost-effectiveness analysis of Tdap vaccination during pregnancy compared with postpartum vaccination with or without vaccination of other close contacts (ie, cocooning). We analyzed infant pertussis cases, hospitalizations, and deaths, as well as direct disease, indirect, and public health costs for infants in the first year of life. All costs were updated to 2011 US dollars.RESULTS: Pregnancy vaccination could reduce annual infant pertussis incidence by more than postpartum vaccination, reducing cases by 33% versus 20%, hospitalizations by 38% versus 19%, and deaths by 49% versus 16%. Additional cocooning doses in a father and 1 grandparent could avert an additional 16% of cases but at higher cost. The cost per qualityadjusted life-year saved for pregnancy vaccination was substantially less than postpartum vaccination ($414 523 vs $1 172 825).CONCLUSIONS: Tdap vaccination during pregnancy could avert more infant cases and deaths at lower cost than postpartum vaccination, even when postpartum vaccination is combined with additional cocooning doses. Pregnancy dose vaccination is the preferred alternative to postpartum vaccination for preventing infant pertussis. Pediatrics 2013;131: e1748-e1756 AUTHORS:

“…22 Our surveys, comparing pre-and post-pandemic cohorts, demonstrate a shift in knowledge and attitudes during and immediately following the 2009 pandemic influenza A (H1N1), consistent with other studies reporting trends in vaccine uptake among pregnant women following the pandemic. 13,19,23,24 Almost twice as many of the post-pandemic cohort knew that seasonal flu was more severe in pregnant women, and they were also aware that the pandemic virus caused more severe illness in pregnant women than the seasonal flu virus. Attitudes also seemed significantly affected by the experience of living through the pandemic.…”
