Abstract Background The ACIP recommends influenza and Tdap vaccination during pregnancy to reduce the risk of influenza and pertussis in the mother and her infant. We assessed influenza and Tdap vaccination coverage and associated factors among pregnant women enrolled in PREVAIL, a prospective birth cohort study in Cincinnati, OH. We assessed sensitivity and specificity of self report for both vaccines against state registry, maternal healthcare provider, and work-place records. Methods We enrolled and interviewed 265 pregnant women regarding self-reported receipt of influenza and Tdap vaccines, and obtained vaccine records from registry, electronic medical record, provider, employer, or pharmacy. We grouped subjects by documented vaccination status and analyzed demographic variables and vaccine attitudes regarding efficacy, safety, and hesitancy using unadjusted Fisher exact tests. We analyzed sensitivity and specificity of maternal recall. Results We identified documentation of influenza and Tdap vaccine receipt during pregnancy in 172/265 (64.9%) and 238/265 (89.8%) of women, respectively (Figure 1); by self report, 177/265 (66.8%) reported receiving influenza and 221/265 (83.4%) Tdap vaccine. The two most common primary reasons cited for receiving influenza vaccine were “to protect my baby” (36.7%) and “to protect myself” (26%; Figure 2). Pregnant women were more likely to get Tdap vaccine if a healthcare worker recommended it (OR 5.4). Subjects were more likely to get influenza vaccine if they believed it was effective in preventing influenza in themselves (OR 9.0) or their babies (OR 8.1). While positive recall had a high concordance (95.2% and 93.4% for influenza and Tdap, respectively), 12.5% and 32.1% of mothers incorrectly recalled not receiving an influenza or Tdap vaccine, respectively, that was documented as received in the records (Figure 3). Conclusion We found high concordance between maternal recall and verification for both influenza and Tdap vaccines. In this single-site cohort of 265 women, self report was a reliable measure of vaccination status among pregnant women. Provider communication to pregnant women regarding effectiveness of influenza and Tdap vaccinations for themselves and their infants may lead to higher maternal vaccination rates.

Background: Although recall-based data are collected by survey when the vaccination records are not available, the preferred estimates remain the record-based ones due to the limited validity of recall-based data. However, the evidence on validity of maternal recalls is limited and varied across vaccine types. To close the gaps, we validated the maternal recall on vaccination against record-based data in six districts in Zhejiang Province, China. Methods: We used a cross-sectional survey of about 648 households with mothers who delivered in the last 12 months prior to the survey in October 2017, from six districts in Zhejiang Province. Vaccination status on five vaccine types scheduled before 12 months of age were collected through maternal recall and vaccination records. The level of agreement and recall bias between the two resources, the sensitivity and specificity of maternal recall were evaluated. Risk factors for maternal recall bias were also identified through logistic regression model for each type of vaccine. Results: The level of agreement between recall and record was above 90% across vaccine types, with the recall bias ranged from 2.2% to 9.7%. Recall bias due to over-reporting was slightly higher than that due to under-reporting. Recall bias was positively associated with high parity, home delivery, younger mothers, mothers with low education, and migrant mothers. Conclusions: This study indicated most of the vaccination status across vaccine types was accurately identified through maternal recall and supported the use of maternal recall to estimate the vaccination coverage as an alternative in the absence of record-based data.

Abstract Background The resurgence of measles globally and the increasing number of unvaccinated clusters call for studies exploring factors that influence measles vaccination uptake. Armenia is a middle-income post-Soviet country with an officially high vaccination coverage. However, concerns about vaccine safety are common. The purpose of this study was to measure the prevalence of measles vaccination coverage in children under three years of age and to identify factors that are associated with measles vaccination in Armenia by using nationally representative data. Methods Cross-sectional analysis using self-report data from the most recent Armenian Demographic Health Survey (ADHS VII 2015/16) was conducted. Among 588 eligible women with a last-born child aged 12–35 months, 63 women were excluded due to unknown status of measles vaccination, resulting in 525 women included in the final analyses. We used logistic regression models in order to identify factors associated with vaccination status in the final sample. Complex sample analyses were used to account for the study design. Results In the studied population 79.6% of the children were vaccinated against measles. After adjusting for potential confounders, regression models showed that the increasing age of the child (AOR 1.07, 95% CI: 1.03–1.12), secondary education of the mothers (AOR 3.38, 95% CI: 1.17–9.76) and attendance at postnatal check-up within two months after birth (AOR 2.71, 95% CI: 1.17–6.30) were significantly associated with the vaccination status of the child. Conclusions The measles vaccination coverage among the children was lower than the recommended percentage. The study confirmed the importance of maternal education and attending postnatal care visits. However, the study also showed that there might be potential risks for future measles outbreaks because of delayed vaccinations and a large group of children with an unknown vaccination status.

The study aimed to determine influenza vaccine uptake among medical students and their intention to receive a hypothetical Ebola or COVID-19 vaccine. This cross-sectional questionnaire-based study was performed in 2015 and 2020 on 675 medical students at the Medical University of Warsaw, Poland. In 2020, the influenza vaccination coverage was 36.5%, and students were almost five times more likely to be vaccinated than in 2015 (OR = 4.8; 95% CI: 3.1–7.5). In 2020, the survey was conducted during the first university campaign targeted at free influenza vaccinations for all students, as well as during the first lockdown in Poland due to the COVID-19 pandemic. In 2020, clinical students (4th–6th study year) were significantly more often vaccinated than preclinical students (p < 0.001), in contrast to 2015. A majority—67.0% and 94.6%—of students expressed their intention to receive a hypothetical Ebola or COVID-19 vaccine, respectively. Among the medical students, influenza vaccination status was a predictor of the intention to receive a COVID-19 vaccine. Influenza vaccine uptake among medical students has increased significantly, but it is still not optimal; thus, further educational efforts are needed to convince those who are hesitant regarding vaccines. A high number of students reported their intention to receive a COVID-19 vaccine, and it is crucial to support their positive attitude about it.

Background: Influenza vaccination is the most effective strategy to prevent comorbidity and mortality of this infection in pregnant women. Objectives: The current study aimed at evaluating the influenza vaccination rate and its related factors among pregnant women. Methods: The current cross-sectional study was conducted on 520 pregnant women referring to antenatal clinics of tertiary hospitals affiliated to Kerman University of Medical Sciences from January to April 2019 in Kerman city, Iran. The collected data through a form distributed among the subjects were analyzed using SPSS version 22. Results: The influenza vaccination coverage rate was 30.0% (95% confidence interval (CI): 26.1 - 34.1) among the pregnant women. Age older than 30 years (AOR = 3.79; 95%CI: 1.55 - 9.24), being employed (AOR = 2.44; 95%CI: 1.01 - 5.88), having an underlying chronic disease (AOR = 4.39; 95%CI: 1.33 - 14.51), receiving recommendation to undergo influenza vaccination (AOR = 65.76; 95%CI: 11.04 - 391.48), and having good knowledge of influenza vaccine (AOR = 9.64; 95%CI: 3.87 - 24.02) increased the likelihood of receiving influenza vaccine. Conclusions: The current study highlighted that the influenza vaccination coverage rate was suboptimal. Also, findings of the current study suggested that influenza vaccination, as an important component of antenatal care services, should be considered by health policymakers. Furthermore, educating pregnant women and healthcare providers can improve compliance with influenza vaccination.

Background: Puberty is a milestone in child and adolescent development, yet a feasible tool to accurately assess pubertal stage in community context has not been validated in Vietnam. Aim: This study was conducted to validate pubertal self-report among Ho Chi Minh City children and adolescents in comparison with paediatrician’s assessment. Methods: 80 girls and 76 boys aged from 6 to 17 years old from 5 schools in Ho Chi Minh City were recruited. Self-administered questionnaires about sexual maturation were distributed to participants and results were compared with physician’s pubertal examination. Kappa statistic and Kendall’s τ b were used to evaluate validity of the questionnaire. Results: Boys tended to overestimate their development stages while girls tended to underestimate. Fair to almost perfect agreement between students’ reports and paediatricians’ evaluation, along with high concordance was recorded, however younger boys (aged 6-11) showed limited evaluation of their own sexual maturation. Conclusion: This method was inaccurate to evaluate younger boys’ sexual maturation; however, acceptable accuracy in sexual maturation estimation among younger girls and adolescents could allow it to serve as an effective screening tool in community context.

Background: There is limited information on vaccination coverage and characteristics associated with vaccine uptake in Aboriginal and/or Torres Strait Islander adults. We aimed to provide more current estimates of influenza vaccination coverage in Aboriginal adults. Methods: Self-reported vaccination status (n=559 Aboriginal and/or Torres Strait Islander participants, n=80,655 non-Indigenous participants) from the 45 and Up Study, a large cohort of adults aged 45 years or older, was used to compare influenza vaccination coverage in Aboriginal and/or Torres Strait Islander adults with coverage in non-Indigenous adults. Results: Of Aboriginal and non-Indigenous respondents aged 49 to <65 years, age-standardised influenza coverage was respectively 45.2% (95% CI 39.5–50.9%) and 38.5%, (37.9–39.0%), p-value for heterogeneity=0.02. Coverage for Aboriginal and non-Indigenous respondents aged ≥65 years was respectively 67.3% (59.9–74.7%) and 72.6% (72.2–73.0%), p-heterogeneity=0.16. Among Aboriginal adults, coverage was higher in obese than in healthy weight participants (adjusted odds ratio (aOR)=2.38, 95%CI 1.44–3.94); in those aged <65 years with a medical risk factor than in those without medical risk factors (aOR=2.13, 1.37–3.30); and in those who rated their health as fair/poor compared to those who rated it excellent (aOR=2.57, 1.26–5.20). Similar associations were found among non-Indigenous adults. Conclusions: In this sample of adults ≥65 years, self-reported influenza vaccine coverage was not significantly different between Aboriginal and non-Indigenous adults whereas in those <65 years, coverage was higher among Aboriginal adults. Overall, coverage in the whole cohort was suboptimal. If these findings are replicated in other samples and in the Australian Immunisation Register, it suggests that measures to improve uptake, such as communication about the importance of influenza vaccine and more effective reminder systems, are needed among adults.

Objective Pregnant women are at increased risk of serious complications from influenza and are recommended to receive an influenza vaccination during pregnancy. The objective of this study was to assess trends, timing patterns, and associated factors of influenza vaccination among pregnant women. Methods We used 2010-2018 MarketScan data on 1 286 749 pregnant women aged 15-49 who were privately insured to examine trends and timing patterns of influenza vaccination coverage. We examined descriptive statistics and identified factors associated with vaccination uptake by using multivariate log-binomial and Cox proportional hazard models. Results In-plan influenza vaccination coverage before delivery increased from 22.0% during the 2010-2011 influenza season to 33.2% during the 2017-2018 influenza season. About two-thirds of vaccinated women received the vaccine in September or October during each influenza season. For women who delivered in September through May, influenza vaccination coverage increased rapidly at the beginning of influenza season and flattened after October. For women who delivered in June through August, influenza vaccination coverage increased gradually until February and flattened thereafter. Most vaccinated women who delivered before January received the vaccine in the third trimester. Increased likelihood of being vaccinated was associated with age 31-40, living in a metropolitan statistical area, living outside the South, enrollment in a consumer-driven or high-deductible health plan, being spouses or dependents of policy holders, and delivery in November through January. Conclusions Despite increases during the past several years, vaccination uptake is still suboptimal, particularly after October. Health care provider education on timing of vaccination and recommendations throughout influenza seasons are needed to improve influenza vaccination coverage among pregnant women.
