Abstract Background Maternal influenza and pertussis vaccinations have been proven safe and effective in reducing maternal and infant morbidity and mortality. Though recommended, not all pregnant women receive these important vaccines. We aimed to evaluate the vaccine coverage of maternal immunization in pregnancy for seasonal influenza and acellular pertussis and elucidate the reasons for non-vaccination among pregnant women. The secondary objective was to describe factors that affect vaccine uptake. Methods A cross sectional observational study using anonymous questionnaires distributed to women in the maternity ward or pregnant women hospitalized in the high-risk ward, between Nov 2017 and June 2018, In an Israeli tertiary hospital. Results Of 321 women approached, 313 were eligible, with a total of 290 women completing the questionnaire (92.6%). We found a 75.9% (95% CI 71–81) and 34.5% (95% CI 29–40) vaccination rate for pertussis and influenza vaccines, respectively. The most prominent reason for not receiving the pertussis vaccine was being under-informed (24%). Influenza vaccine was not received mainly due to concerns about vaccine efficacy (28%). Other factors influencing vaccine uptake included education, prior childbirth and vaccine recommendations made by the provider. Conclusion Although maternal vaccination of pertussis and influenza is officially recommended, vaccine uptake is suboptimal. Our study suggests a central role for medical providers in diminishing the concerns about safety and efficacy, and presents novel factors influencing compliance rates, like seasonality and number of prior births.

Abstract Background Influenza in pregnancy is associated with elevated morbidity and mortality. Influenza vaccines are both safe and effective in pregnancy, supporting routine use in this population. Even though influenza vaccination in Mexico is recommended for pregnant women, there are no publications of influenza vaccine coverage in pregnancy. This is the first Latin American survey done only in physicians aiming to assess the knowledge, beliefs, and attitudes that Mexican Obstetrics-Gynecologists (OBG) and Family Physicians (FP) have towards influenza and influenza immunization during pregnancy. Methods A cross-sectional survey was conducted, both paper-based and online. The questionnaire was composed of 35 questions, which addressed general knowledge of influenza, recommendations for vaccination during pregnancy, and beliefs and attitudes concerning the acceptability of the vaccine in pregnant women. Results A total of 206 completed surveys were available, 98 (47.6%) from OBG, 108 (52.4%) from FP. Regarding current practicing medical institutions, 76 (37%), 69 (34%), 31 (14.5%), 30 (14.5%) reported working for the Mexican Institute of Social Security, Private Sector, Secretariat of Health, or a combination of all respectively, representing an estimated 2,472 daily pregnancy consultations. About a quarter (26.2%) reported not having a notion that influenza is more severe among pregnant women. More than half (51.5%) ignored the potential side effects of influenza infection on the fetus. The majority (56.8%) did not know when vaccination during pregnancy should occur. Pregnancy as a risk factor for developing influenza complications was known only in 48.1%. Also, 46.1 % believed that vaccination only confers protection to the mother, but not to the fetus. Nevertheless, 96.1% considered that immunization against influenza during pregnancy is a safe and effective preventive intervention. A results’ summary is shown in Figure-1. Conclusion Based on this survey, current knowledge of OBG and FP for influenza morbidity and mortality during pregnancy, and the importance of influenza vaccination in pregnant women, is poor. Mandatory recommendations to educate medical providers regarding influenza vaccination during pregnancy in Mexico are necessary, even as imperative for CME credits.

Introduction: Seasonal influenza vaccination is recommended for pregnant women, but half of the pregnant women in the United States remain unvaccinated. Vaccine coverage in U.S.–Mexico border states has not been examined in depth even though risk factors for low vaccine coverage exist in these states, especially in the counties bordering Mexico. Method: Using 2012-2014 New Mexico (NM) Pregnancy Risk Assessment and Monitoring System data, this study examined the weighted annual seasonal influenza vaccination rates and the relationship of various factors to vaccination among NM residents with a live birth during those years. Results: Among respondents, 53.8% were Hispanic, 15.7% were Native American, and 30.5% were non-Hispanic White. The vaccination rate in NM increased from 49.0% in 2012 to 64.8% in 2014. The adjusted odds of vaccination were higher among women whose health care provider recommended/offered vaccination during the year prior to delivery compared to women whose provider did not (AOR = 11.92, 95% confidence interval [CI: 9.86, 14.42]) and among those living in the U.S.–Mexico nonborder counties compared to those living in the border counties (AOR = 1.23, 95% CI [1.18, 1.25]). Conclusion: Efforts to increase the vaccination rate among pregnant women in border states should concentrate on health care providers and the highest risk women, such as those resident in the border region.

Abstract Background Vaccinating children against influenza has shown both direct and indirect beneficial effects. However, despite being offered free of charge, childhood influenza vaccine coverage in Israel has been low. Our objective was to evaluate the factors associated with childhood influenza vaccination in Israel. Methods A cross-sectional language-specific telephone survey was conducted among adults 18 years or older, to examine childhood influenza vaccination practices and their associations with socio-demographic and relevant health variables. We further explored the reasons for these practices among parents. Multivariate logistic regression was used to identify factors associated with childhood influenza vaccine acceptance. Results Of a total of 6518 individuals contacted by mobile phone, 1165 eligible parents, ≥18 years old with children 1–18 years of age, were interviewed, and 1040 of them completed the survey successfully. Overall, factors associated with childhood influenza vaccination were younger child’s age, influenza vaccination of other family members and belonging to the Arab population group. No association was found between childhood influenza vaccination and routine childhood vaccine uptake. Several of the parents’ reasons for vaccine acceptance - preventing influenza or its transmission, awareness regarding the need for influenza vaccination and receipt of invitation to get vaccinated - differed significantly between Jewish and Arab parents. Several reasons reported by parents for not vaccinating children against influenza, indicated a likelihood to accept influenza vaccine outreach efforts. Such reasons were reported by 27.5% of Jewish parents and 37.5% of Arab parents. Conclusions We found that certain demographic factors were associated with childhood influenza vaccination in Israel. Several reasons described by the parent for not vaccinating their children indicate that outreach efforts are likely to increase childhood influenza vaccination. Addressing population group-specific needs is recommended to optimize the success of influenza vaccine outreach efforts.

Nigeria is making effort to address the child mortality burden by increasing vaccine coverage rates, yet the vaccine coverage falls short of 90% target. Scaling up of new and under-used vaccines to 90% coverage could save more than 600,000 Nigerian children. Healthcare givers knowledge of vaccine used for immunization is essential to increase the vaccine uptake rates. This study assesses the knowledge of routine, underutilized and future vaccines among health workers. A cross sectional descriptive study was done among health care workers at a tertiary health facility in Nigeria. Using a pre-tested semi structured interviewer administered questionnaire, 220 respondents were selected by cluster sampling technique. The health workers’ knowledge of these vaccines was assessed using a scale developed for the study. Data collected were analyzed using SPSS version 22.The mean age of the respondents was 31.9 + 5.7 years . Doctors and nurses formed more than half of the respondents, 51.8% (n=114). About three quarters of respondents 72.3% (n=159) had good knowledge of vaccines used in routine immunizations. Knowledge of under-utilized and future vaccine was low with less than a fifth 18.6% (n=41) and one tenth 9.1% (n=20) having good knowledge scores respectively. Similarly, poor perception scores of future vaccines were observed in 90.1% (n=218) of the respondents. Only marital status was associated with knowledge of underutilized vaccines (p<0.05) and no association was observed between other sociodemographic variables and knowledge of these vaccines (P>0.05). The awareness level of health care workers on routine immunization is high. Their knowledge and perception of under-utilized and future vaccines were however low. There is, therefore, need for more training and retraining of health care workers on the vaccines.

ABSTRACTBackgroundHuman papillomavirus (HPV) is the main cause of cervical cancer and contributes to a number of other cancers that affect both men and women. Vaccines exist that offer protection against the most common cancer-causing HPV types. In England, a school-based vaccination programme for girls has been in place since 2008 but vaccine coverage rates have declined since its introduction. Understanding variation between schools and between local authorities may help to inform quality improvement and guide policy development and commissioning.MethodsCross-sectional, ecological analysis of vaccine uptake among 164 schools representing 13,127 children in eight out of ten local authorities in Greater Manchester. Logistic mixed effects regression models were used to test for associations between school level factors and vaccine uptake, while allowing for variation between local authorities.ResultsIn multivariable mixed effects models, lower vaccination rates were associated with: increasing numbers of children eligible for vaccination; increasing proportions of children eligible for free school meals; increasing proportions of children with English as an additional language; Ofsted ‘inadequate’ ratings; Christian and Muslim faith schools; independent schools and special schools.ConclusionsConsistent with previous studies on vaccine uptake, this study identifies a number of factors that are associated with uptake of the school-based HPV vaccine programme. We also show that local authority variation remains after adjustment for the mix of schools in each area. This evidence may be used to guide vaccine providers, commissioners, and policymakers who want to increase uptake of the school-based HPV vaccine.

Tetanus Immunization

Even though attempts have been effectively applied to eradicate the neonatal tetanus through widespread childhood vaccination and improved conditions at delivery, it remains major cause of infant mortality and continues a problem of public health in developing countries including Yemen.  The aims of this study were to determine the tetanus immunization status, the association between the risk factors and failure of protection in pregnant women at time of delivery. This cross-sectional study included 476 women seeking care for delivery at Al Thawra Modern General Hospital and Al Sabain Hospital, women age ranged from 16-49 years old. Immunization information and factors affecting it were obtained through a standard questionnaire. Serum samples were collected and level of IgG antibody against Clostridium tetani was measured by ELISA technique. Protected women were defined as those with serum antibody levels > or = 0.6 IU/ml.  The total vaccine covering rate of tetanus was 87%, and  maternal vaccine rate was 33.6%, the protective rate at time of delivery was 68.5%. There were significant association between  unvaccinated (OR=18.6), older ages (OR=1.7), rural residency (OR=34) and malaria infection during pregnancy (OR=2.9); with protection failure in pregnant women at time of delivery. It can be concluded that the total vaccine coverage rate and antenatal tetanus vaccine rate were insufficient. In addition, the protective rate at time of delivery was low and large numbers of neonate are susceptible to neonatal tetanus and death. Vaccinating every pregnant woman with at least one dose of TT would be an affordable and effective way to protect against neonatal tetanus, and would be a step toward eliminating the deaths that continue to occur due to this preventable disease in Yemen.

Vaccination Recommendation

Abstract Background Seasonal influenza vaccination has been recommended for pregnant women in Germany since 2010. The aim of this study was to examine prevalence and determinants of receipt of provider recommendation for influenza vaccination as well as influenza vaccination uptake during pregnancy. Methods We analysed data from the “KUNO Kids Health Study”, a prospective birth cohort. During the study period (5th July 2015 to 27th June 2018) data were collected from participating mothers by interview and questionnaire. According to Andersen’s behavioural model of health services use potential influencing factors describing the circumstances and characteristics of the mothers and their pregnancies which are potentially affecting whether women receive a recommendation for a vaccination or whether they utilize influenza vaccination were classified into three domains: ‘predisposing characteristics’, ‘enabling resources’ and ‘need’. Using multivariable logistic regression models odds ratios (OR) and corresponding 95% confidence intervals (95% CI) were calculated. Results As a combined result across three flu seasons, 368 of 1814 (20.3%) women received an influenza vaccination recommendation during pregnancy. Having had a high-risk pregnancy increased the odds of receiving a vaccination recommendation (OR = 1.3; 95% CI = 1.0–1.6; p = 0.045). In contrast, pregnancy onset in summer (OR = 0.7; 95% CI = 0.5–1.0; p = 0.027), autumn (OR = 0.4; 95% CI = 0.3–0.5; p < =0.001) or winter (OR = 0.5; 95% CI = 0.3–0.6; p < =0.001) (compared to spring) as well as mother’s birthplace outside Germany (OR = 0.6; 95% CI = 0.4–0.9; p = 0.023) reduced the chance of getting a vaccination recommendation. Two hundred forty-two of one thousand eight hundred sixty-five (13%) women were vaccinated against influenza during pregnancy. Having received a vaccination recommendation was strongly associated with vaccination uptake (OR = 37.8; 95% CI = 25.5–55.9; p < =0.001). Higher health literacy status was also associated with a higher chance of vaccination uptake (OR = 1.7; 95% CI = 1.2–2.6; p = 0.008), whereas pregnancy onset in autumn (compared to spring) reduced the chance (OR = 0.5; 95% CI = 0.3–0.8; p = 0.008). Conclusions At 13% the uptake rate of influenza vaccination is low. Having received a recommendation to vaccinate was strongly associated with uptake but only one fifth of all mothers report such a recommendation. Raising awareness in physicians regarding vaccinating during pregnancy seems to be of essential importance to increase vaccine uptake and to prevent influenza-related complications in pregnant women.
