Influenza and Tetanus, Diphtheria, and Acellular Pertussis Vaccination During Pregnancy, Pregnancy Risk Assessment Monitoring System, 2019

Abstract Background Influenza and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccines is recommended for pregnant women to protect themselves and their infants from adverse health outcomes. Objectives To estimate the prevalence of maternal influenza and Tdap vaccination and determine factors associated with receipt of these vaccines. Methods We analyzed 2019 data from the Pregnancy Risk Assessment Monitoring System, from 43 jurisdictions. We estimated the overall prevalence of women reporting receipt of a healthcare provider offer or recommendation for influenza vaccine (n=44,528), and influenza vaccine during the 12 months before delivery (n=44,213). We also estimated Tdap vaccine receipt during pregnancy from the 21 jurisdictions (n=22,972). Maternal influenza and Tdap vaccination were examined by selected maternal characteristics and by jurisdiction. Results Overall, 86.4% of women reported being offered or recommended an influenza vaccination, and 60.8% of women reported receiving an influenza vaccination in the 12 months prior to their delivery, ranging from 36.0% in Puerto Rico to 82.1% in Rhode Island. Tdap receipt during pregnancy was 73.7%, ranging from 52.2% in Mississippi to 85.1% in Vermont. Prevalence of influenza vaccination was lower among women aged 18–24 years (52.2%), who are non-Hispanic black (44.5%), with a high school diploma or less education (51.3%), with no prenatal insurance (43.2%), having no (42.0%) prenatal care, with ≥3 previous live births (49.3%) and not offered or recommended the influenza vaccine by a healthcare provider (20.0%). Tdap vaccination also varied by all characteristics examined and was lower among similar groups of women observed to have lower influenza vaccination uptake. Conclusion In 2019, influenza and Tdap vaccination were suboptimal among women with a recent live birth. It is important that U.S. jurisdictions provide equitable access to these vaccines during pregnancy. These results may also inform efforts for vaccination for other infectious diseases among pregnant women.

Abstract Background Influenza vaccination has been shown to reduce influenza risk in pregnant women and their infants who are not yet age-eligible for vaccine. Ascertainment of vaccination history is important for vaccine safety and effectiveness evaluations. Our goals were to (a) determine coverage, location, and timing of maternal influenza vaccination and (b) compare a subset of self-reported influenza vaccinations with documented vaccine records. Methods We enrolled children < 18 years. with acute respiratory illness in 7 pediatric hospitals and emergency departments in the New Vaccine Surveillance Network from December 1, 2016 to October 31, 2018. We interviewed all mothers of enrolled infants < 1 year, and obtained mother’s influenza vaccine information while pregnant. As an option, sites obtained maternal influenza vaccine records from reported sources (e.g., registries, provider records, pharmacies). Results Among 5,458 mothers, 2,944 (54%) self-reported receiving influenza vaccine during pregnancy (57% in 2016–2017; 51% in 2017–2018), varying from 49% to 74% by site. Among self-reported vaccinees, 17%, 36%, and 47% received vaccine during their first, second, and third trimester, respectively. Most women (76%) were vaccinated at their OB/GYN or midwife office, 7% at their primary care provider, 7% at their workplace, and 5% at a retail pharmacy. Among 1,338 infants < 6 months. during early influenza season (i.e., born from June to August) and thus ineligible for vaccination, only 46% of mothers reported receiving vaccine during pregnancy (42% reported not receiving it, 12% were unsure). Of 2,242 women for whom vaccine verification was attempted, 1,491 (67%) self-reported receiving influenza vaccine during pregnancy; of those, documentation of vaccine receipt was found for 901 (60%). Conclusion Influenza vaccination coverage among pregnant women was suboptimal, potentially increasing the risk of influenza in unvaccinated pregnant women. Infants born to unvaccinated women, particularly those born from June to August, may also be at higher risk since they are not age-eligible to receive vaccine before influenza season. The optimal approach to ascertainment of maternal vaccination history with accuracy and completeness merits further investigation. Disclosures All authors: No reported disclosures.

Abstract BackgroundOur objective was to investigate: (1) the proportion of influenza vaccination, attitudes, and barriers among pregnant women, (2) the proportion of obstetrics and gynecology (OBGYN) doctors who routinely recommend influenza vaccination in pregnant women, and (3) the influencing factors in Korea, during the flu season of 2019-2020, following the introduction of free influenza vaccination program for pregnant women.MethodsTwo separate anonymized questionnaires were developed for pregnant or postpartum women and physicians, and distributed to public or private healthcare centers and clinics, in South Korea. The proportions of women who received influenza vaccination during pregnancy and OBGYN doctors who routinely recommend influenza vaccine for pregnant women were analyzed. Independent influencing factors of influenza vaccination and OBGYN doctors’ routine recommendation for pregnant women were analyzed using multivariate logistic regression analysis, respectively.Result The self-reported proportion of influenza vaccination during pregnancy among 522 women was 63.2%. Independent factors influencing maternal influenza vaccination were ‘(ever) received information about influenza vaccination during pregnancy’, ‘information obtained from OBGYN doctors’, and ‘2nd/3rd trimester or postpartum period’ (OR 8.988, 95% CI 4.21–19.188, p < 0.001, OR 2.611, 95% CI 1.705-3.998, p < 0.001 and OR 3.082, 95% CI 1.508–6.297, p < 0.001, respectively).In 372 OBGYN doctors, the proportion of doctors with the routine recommendation of influenza vaccine for pregnant women was 76.9%. Independent factors affecting the routine recommendation were: 1) affiliation with private hospital or clinic (OR 4.508, 95% CI 2.225–9.133, p<0.001); 2) awareness of guidelines (OR 3.153, 95% CI 1.118–8.894, p=0.03); (3) awareness of 2019 National free influenza vaccination program for pregnant women (OR 4.955, 95%CI 2.377–10.329, p<0.001). For a future recommendation of influenza vaccine for pregnant women, the guidelines proposed by the government or public health care [108 (46%)] and academic committees [59 (25%)] were most commonly chosen by OBGYN doctors.Conclusion This study demonstrated that providing information about maternal influenza vaccination and the recommendation by OBGYN doctors are crucial for increasing the vaccination coverage in pregnant women.
