Exploring Perceptions and Barriers: A Health Belief Model-Based Analysis of Seasonal Influenza Vaccination among High-Risk Healthcare Workers in China.

The annual seasonal influenza vaccination rate among high-risk healthcare workers (HCWs) has fallen below expectations, underscoring the importance of exploring the impact of perception on vaccination behavior. An online survey, grounded in the Health Belief Model (HBM), was administered to high-risk healthcare workers at West China Hospital. The data analysis encompassed descriptive statistics, logistic regression for univariate analysis, and path regression for multivariate analysis. A total of 1845 healthcare workers completed the survey, with an acceptance rate of 83.90% (95% CI, 82.20-85.60%). Path analysis revealed significant correlations between vaccination acceptance and perceived susceptibility (β = 0.142), perceived benefits (β = 0.129), perceived barriers (β = 0.075), exposure to vaccination advertisements (β = 0.115), and knowledge about seasonal influenza (β = 0.051). Vaccination education efforts should prioritize elucidating the risks associated with the disease and emphasizing the benefits of vaccination. Furthermore, leveraging advertising proves to be an effective strategy for promotion.

Pediatric influenza vaccination in the perioperative setting: A quality improvement project.

Unmet need for seasonal influenza vaccination administration to pediatric patients exists at national and local levels. Vaccination during the perioperative period remains controversial, though opportunity exists to meet vaccination need through perioperative programs. The initial SMART Aim of this quality improvement initiative was to establish and increase seasonal influenza vaccination rate in eligible patients during in person preoperative clinic visits in a pediatric perioperative surgical home (PSH) to 10%. Informed by each prior season's experience, we increased our SMART Aim target for vaccinations in seasons two and three to 15 and 18%, respectively. Following the Model for Improvement methodology, the PSH team developed and implemented a perioperative pediatric influenza vaccination program. Across three influenza seasons, key interventions included updates to organizational perioperative vaccination policy, obtaining material influenza vaccination supplies, development of EHR tools, PSH staff education, and communication with patient-families. Rate of eligible patients receiving influenza vaccination at their PSH clinic appointment was tracked over time. Influenza vaccination rates were reported monthly during Season 1, then weekly during seasons two and three. The balancing measure was same day surgery case cancellations related to influenza vaccination given at PSH clinic appointment. Statistical analysis methods utilized include Shewart's control chart and statistical process control (SPC) standards. Special cause variation was determined by eight or more consecutive data points above or below the centerline. The influenza vaccination rates in each of the three influenza seasons exceeded vaccination rate goals of 10, 15, and 18%, respectively. A total of 695 vaccines have been administered since program inception. No same day surgical case cancellations were observed as balancing measure. Over three consecutive influenza vaccination seasons, we safely established and met vaccination rate goals of 10, 15, and 18% to eligible patients during preoperative clinic visits within a pediatric PSH system. Through iterative PDSA cycles, we continue to identify opportunities for future improvement. This suggests that the perioperative period presents opportunity for seasonal influenza vaccination with potential program expansion to include routine vaccines of childhood.

A Cross-Sectional Survey of Knowledge, Attitude, and Practices Regarding Influenza Vaccination Among Jordanians Aged 18-64 Years with Chronic Diseases.

Influenza is a frequent infectious disease that can be prevented and is associated with significant mortality and morbidity. The most economical way to prevent influenza is through vaccination, although this method is not widely used. This study aimed to assess the seasonal influenza vaccination rates and the knowledge and attitudes of Jordanian adults with chronic illnesses toward the influenza vaccine. A cross-sectional design was employed. A 26-item online survey was used to gather data about patients' knowledge of and attitudes toward the influenza vaccine as well as their status as influenza vaccine recipients. A total of 19% of the 564 study participants received an influenza vaccination. Most (81%) of individuals reported inconsistent vaccination uptake. The most important factor affecting vaccination is the belief that the flu is not a threat (39%) and that their doctors did not advise them about the vaccination (32%). Participants with no health insurance and those with public insurance had a lower level of vaccination than those with private insurance (p= 0.008). The adult population of Jordan with chronic diseases has subpar immunization rates. What is also revealed is a blatant misunderstanding about the value of routine influenza vaccination. These findings emphasize how urgently the public needs to be made aware of the effectiveness of the influenza vaccine.

The effectiveness of interventions to improve the seasonal influenza vaccination uptake among nurses: A systematic review.

Seasonal influenza is a significant cause of mortality and morbidity worldwide. Despite annual recommendations, influenza vaccination uptake rates are disproportionately lower among nurses compared to other health care professionals, especially when compared to physicians. Nurses have an additional risk of exposure to influenza infection due to the nature of their work. To determine the effectiveness of interventions in increasing seasonal influenza vaccination uptake among nurses. Evidence on the effectiveness of interventions to improve seasonal influenza vaccination uptake among nurses was systematically reviewed. A comprehensive search of six electronic databases and grey literature was undertaken. A minimum of two reviewers completed study selection, data extraction and risk of bias assessment independently. One hundred and thirty-four studies were identified of which one cluster randomised trial met the inclusion criteria. The results of the included study found the implementation of an intervention with multiple components increased nurses' seasonal influenza vaccination rates during a single influenza season in geriatric healthcare settings in France. As the evidence in this review was very limited, it was not possible to make recommendations regarding which interventions were effective at increasing the seasonal influenza vaccination rate for nurses. This systematic review highlights a lack of high-quality studies that assessed interventions to improve the seasonal influenza vaccination of nurses. In view of the likelihood of influenza and the coronavirus (COVID-19) pandemic occurring together, it is imperative to have evidence on effective interventions for the nursing workforce and for policy decision makers.

Low uptake of seasonal influenza vaccination in Al-Jouf region of Saudi Arabia

IntroductionSeasonal influenza is a contagious viral respiratory condition typically occurring in the fall to early spring months of the year globally. The risk of infection from seasonal influenza can be greatly reduced with vaccination. Unfortunately, research has indicated that the seasonal influenza vaccination rate in Saudi Arabia is low. This study assessed the uptake of seasonal influenza vaccination among adults residing in Al-Jouf region, Saudi Arabia. Materials and MethodsA cross-sectional survey targeting adults (20–80 years) residing in Al-Jouf region, Saudi Arabia, was conducted to gather information about their sociodemographic characteristics, chronic conditions, knowledge about periodic health examinations (PHE), regular use of PHE, and uptake of seasonal influenza vaccination. Comparative statistics and a multivariate logistic regression analysis were conducted to determine characteristics associated with the uptake of seasonal influenza vaccination. ResultsA total of 624 respondents completed the survey and participated in this study. Among the participants, 27.4% indicated they visited their primary healthcare centers or hospitals every year to get a seasonal influenza vaccination. The regression analysis showed that the odds of getting a seasonal influenza vaccination were higher among employed respondents (Odds Ratio [OR] = 1.73; P = 0.039), respondents who were employees of the healthcare sector (OR = 2.31; P = 0.001), and those with a higher PHE Knowledge Score (OR = 1.22; P = 0.008), compared to their counterparts. ConclusionsSeasonal influenza is a serious condition warranting appropriate prevention measures, including vaccination. However, this study confirmed low rates of seasonal influenza vaccination in Al-Jouf Region of Saudi Arabia. Interventions to boost vaccination uptake, in particular among unemployed individuals, those not working in the healthcare sector, and those with lower PHE knowledge Scores, are therefore recommended.

What motivates adults to accept influenza vaccine? An assessment of incentives, ease of access, messaging, and sources of information using a discrete choice experiment

Seasonal influenza vaccination rates remain low, and contribute to preventable influenza cases, hospitalizations, and deaths in the US. While numerous interventions have been implemented to increase vaccine uptake, there is a need to determine which interventions contribute most to vaccine willingness, particularly among age groups with vaccination rates that have plateaued at suboptimal levels. This study aimed to quantify the relative effect of multiple interventions on vaccine willingness to receive influenza vaccine in three age groups using a series of hypothetical situations with different behavioral interventions.We assessed the relative impact of four categories of interventions: source of vaccine messages, type of vaccination messages, vaccination incentives, and ease of vaccine access using a discrete choice experiment. Within each category, we investigated the role of four different attributes to measure their relative contribution to willingness to be vaccinated by removing one option from each of the intervention categories. Among the 1,763 Minnesota residents who volunteered for our study, participants expressed vaccine willingness in over 80% of the scenarios presented. Easy access to drop-in vaccination sites had the greatest impact on vaccine willingness in all age groups. Among the younger age group, small financial incentives also contributed to high vaccine willingness.Our results suggest that public health programs and vaccination campaigns may improve their chances of successfully increasing vaccine willingness if they offer interventions preferred by adults, including facilitating convenient access to vaccination and offering small monetary incentives, particularly for young adults.

Influence of Digital Intervention Messaging on Influenza Vaccination Rates Among Adults With Cardiovascular Disease in the United States: Decentralized Randomized Controlled Trial.

BackgroundSeasonal influenza affects 5% to 15% of Americans annually, resulting in preventable deaths and substantial economic impact. Influenza infection is particularly dangerous for people with cardiovascular disease, who therefore represent a priority group for vaccination campaigns.ObjectiveWe aimed to assess the effects of digital intervention messaging on self-reported rates of seasonal influenza vaccination.MethodsThis was a randomized, controlled, single-blind, and decentralized trial conducted at individual locations throughout the United States over the 2020-2021 influenza season. Adults with self-reported cardiovascular disease who were members of the Achievement mobile platform were randomized to receive or not receive a series of 6 patient-centered digital intervention messages promoting influenza vaccination. The primary end point was the between-group difference in self-reported vaccination rates at 6 months after randomization. Secondary outcomes included the levels of engagement with the messages and the relationship between vaccination rates and engagement with the messages. Subgroup analyses examined variation in intervention effects by race. Controlling for randomization group, we examined the impact of other predictors of vaccination status, including cardiovascular condition type, vaccine drivers or barriers, and vaccine knowledge.ResultsOf the 49,138 randomized participants, responses on the primary end point were available for 11,237 (22.87%; 5575 in the intervention group and 5662 in the control group) participants. The vaccination rate was significantly higher in the intervention group (3418/5575, 61.31%) than the control group (3355/5662, 59.25%; relative risk 1.03, 95% CI 1.004-1.066; P=.03). Participants who were older, more educated, and White or Asian were more likely to report being vaccinated. The intervention was effective among White participants (P=.004) but not among people of color (P=.42). The vaccination rate was 13 percentage points higher among participants who completed all 6 intervention messages versus none, and at least 2 completed messages appeared to be needed for effectiveness. Participants who reported a diagnosis of COVID-19 were more likely to be vaccinated for influenza regardless of treatment assignment.ConclusionsThis personalized, evidence-based digital intervention was effective in increasing vaccination rates in this population of high-risk people with cardiovascular disease.Trial RegistrationClinicalTrials.gov NCT04584645; https://clinicaltrials.gov/ct2/show/NCT04584645

Current Epidemiological Data on Community Acquired Pneumonia in Children After Improvements in the Health System and Socioeconomic Changes in Turkiye

In this study, it was investigated that current epidemiological situation and risk factors of community-acquired pneumonia (CAP) in pediatric patients in Türkiye, after socioeconomic changes and health system improvements in the past two decades. In total 1,488 children treated with a diagnosis of pneumonia in Gulhane Training and Research Hospital (Ankara) Pediatrics Department between 2016 to 2021 were included in the present study. The patients’ demographic data, personal and family histories, and socioeconomic status were recorded. Of the 1,488 pediatric patients (mean age; 43.20±41.04 months and 46.8% girls); 108 were aged 0-6 months (7.3%), 672 were aged >6-24 months (45.2%), 444 were aged >24-60 months (29.8%), and 264 were aged >60 months (17.7%). In total, 98.4% of patients underwent routine vaccination and the rate of seasonal influenza vaccination was 5.6%. Additionally, 444 patients (29.8%) had chronic disease; asthma and cerebral palsy were the most common chronic diseases, 276 and 84 patients respectively. A family history of asthma in first-degree relatives was present in 396 patients (26.6%). There have been substantial changes in the epidemiology of CAP in Türkiye, due to socioeconomic changes, increasing urbanization, and health system improvements and the current effects of these changes are presented in our study with comprehensive data that can be used in further comparative studies.

Effectiveness of a pay-it-forward intervention compared with user-paid vaccination to improve influenza vaccine uptake and community engagement among children and older adults in China: a quasi-experimental pragmatic trial

SummaryBackgroundChina has low seasonal influenza vaccination rates among priority populations. In this study, we aimed to evaluate a pay-it-forward strategy to increase influenza vaccine uptake in rural, suburban, and urban settings in China.MethodsWe performed a quasi-experimental pragmatic trial to examine the effectiveness of a pay-it-forward intervention (a free influenza vaccine and an opportunity to donate financially to support vaccination of other individuals) to increase influenza vaccine uptake compared with standard-of-care user-paid vaccination among children (aged between 6 months and 8 years) and older people (≥60 years) in China. Recruitment took place in the standard-of-care group until the expected sample size was reached and then in the pay-it-forward group in primary care clinics from a rural site (Yangshan), a suburban site (Zengcheng), and an urban site (Tianhe). Participants were introduced to the influenza vaccine by project staff using a pamphlet about influenza vaccination and were either asked to pay out-of-pocket at the standard market price (US$8·5–23·2; standard-of-care group) or to donate any amount anonymously (pay-it-forward group). Participants had to be eligible to receive an influenza vaccine and to have not received an influenza vaccine in the past year. The primary outcome was vaccine uptake. Secondary outcomes were vaccine confidence and costs (from the health-care provider perspective). Regression methods compared influenza vaccine uptake and vaccine confidence between the two groups. This trial is registered with ChiCTR, ChiCTR2000040048.FindingsFrom Sept 21, 2020, to March 3, 2021, 300 enrolees were recruited from patients visiting three primary care clinics. 55 (37%) of 150 people in the standard-of-care group (40 [53%] of 75 children and 15 [20%] of 75 older adults) and 111 (74%) of 150 in the pay-it-forward group (66 [88%] of 75 children and 45 [60%] of 75 older adults) received an influenza vaccine. People in the pay-it-forward group were more likely to receive an influenza vaccine compared with those in the standard-of-care group (adjusted odds ratio [aOR] 6·7 [95% CI 2·7–16·6] among children and 5·0 [2·3–10·8] among older adults). People in the pay-it-forward group had greater confidence in vaccine safety (aOR 2·2 [95% CI 1·2–3·9]), importance (3·1 [1·6–5·9]), and effectiveness (3·1 [1·7–5·7]). In the pay-it-forward group, 107 (96%) of 111 participants donated money for subsequent vaccinations. The pay-it-forward group had a lower economic cost (calculated as the cost without subtraction of donations) per person vaccinated (US$45·60) than did the standard-of-care group ($64·67).InterpretationThe pay-it-forward intervention seemed to be effective in improving influenza vaccine uptake and community engagement. Our data have implications for prosocial interventions to enhance influenza vaccine uptake in countries where influenza vaccines are available for a fee.FundingBill & Melinda Gates Foundation and the UK National Institute for Health Research.

Pharmacists' Seasonal Influenza Vaccine Recommendations.

Seasonal influenza vaccination rates among European countries remain low despite the World Health Organization’s recommendations to vaccinate high-risk groups. Healthcare worker recommendations are strong predictors of increased vaccination uptake in the population. Therefore, this study aimed to analyze seasonal influenza vaccination recommendation behavior among pharmacists towards high-risk groups including patients, coworkers, and pharmacists’ family members during the COVID-19 pandemic. This cross-sectional, questionnaire-based research was conducted in Switzerland during the flu season and sent to all members of the Swiss Pharmacist Association. In December 2020, 569 community pharmacists completed the online survey. The influenza vaccination recommendation rates for high-risk patients were 93.6% for the elderly, 70.7% for pregnant women, 65.2% for immunocompromised people, and 60.3% for patients with chronic diseases. Pharmacists tend to recommend influenza immunization to patients more than to family members and colleagues. Holding a certification to administer immunization and personal influenza vaccine history were the main predictors for recommending influenza vaccination to patients, family members, and colleagues. Our results indicated that influenza vaccination recommendation rates in our whole sample of pharmacists, were higher for vaccinated and immunizing pharmacists. Ensuring high vaccinations rates and high ratio of immunizing pharmacists may be important in promoting seasonal influenza vaccination in the general population.

Risk perceptions regarding inclusion of seasonal influenza vaccinations in the school immunization program in Israel: Arab vs. Jewish mothers.

BackgroundThe issue of whether to include seasonal influenza vaccinations in school-located vaccination programs (SLIV) has been examined in many countries, mainly in the context of economic effectiveness and morbidity prevention. Yet not enough studies have examined the impact of parental risk perceptions, health literacy and SLIV on parental vaccination uptake.ObjectivesThe most recent statistics in Israel point to a higher rate of seasonal influenza vaccination among Arab children (aged 7–9 years) than among Jewish children in the same age group. The present study attempts to explain this high vaccination uptake among mothers from Arab society by comparing their risk perceptions regarding seasonal influenza vaccination and disease to those of Jewish mothers. The study further examines the impact of SLIV on parental risk perceptions and influenza vaccination uptake.MethodsThis cross-sectional study included mothers of children in the second and third grades faced with the decision of whether their children should receive the seasonal influenza vaccination at school. The study population included a stratified sample of Jewish mothers (n = 159) and Arab mothers from all the Arab population sub-groups: Muslim, Christian, Druse and Bedouin (n = 534).ResultsA comparison of the Arab and Jewish populations revealed a significant difference in vaccination rates; 61.7% among Arab mothers compared to 33.5% among Jewish mothers (χ2(1) = 39.15, P<0.0001). Moreover, significant differences emerged between the Arab and Jewish populations in health literacy and ability to seek information regarding the seasonal influenza vaccination (t (691) = -5.81, p < 0.0001). While no differences emerged in mothers’ perceptions regarding influenza as a disease (t (691) = 1.20, p = 0.2318), Arab mothers perceived the vaccination to be safer than Jewish mothers (t (691) = 2.74, p = 0.0063) and saw its inclusion in the school-located vaccination program as providing more legitimacy (Z = -6.6719, P < .0001).ConclusionThis study showed that the factors influencing vaccination uptake among both the Arab and the Jewish populations include perceived influenza risk, perceived vaccination risk, inclusion in the school-located vaccination program and health literacy. Moreover, influenza vaccination uptake is higher among those who have positive attitudes toward vaccinations, low risk perceptions regarding the vaccine, and low health literacy that impedes their ability to seek information. The research also points to the need for education and tools to boost health literacy among minority groups so that mothers can make independent and informed decisions about whether or not to vaccinate their children.

Investigation of Seasonal Influenza Vaccination Status in Chronic Kidney Failure Patients Undergoing Hemodialysis: A Survey Study

Aim: Respiratory tract infections due to influenza virus are more mortal in hemodialysis patients than in the healthy population. These patients should be provided with influenza vaccination every year. In this study; the frequency of influenza vaccination in hemodialysis patients in our region and the factors affecting it were investigated. Material and method: A total of 239 patients who had undergone hemodialysis for at least one year were asked the prepared questionnaires. The obtained data were analyzed in SPSS 20 program. Results: The rate of seasonal influenza vaccination of the patients was 87%. Vaccination rates were found to be significantly higher in patients with a duration of hemodialysis longer than five years and those who were vaccinated in the last year (respectively p=0.02, p=0.016). The rate of pneumococcal vaccination in those vaccinated against influenza and the rate of vaccination in the families of these patients were also found to be significantly higher (p&amp;lt;0.01). Conclusion: In this study, it was found that influenza vaccination rates were high in patients undergoing hemodialysis in our region. The reason for this is that the influenza vaccine is provided free of charge to those with chronic diseases every year by the Ministry of Health in our country.

Seasonal influenza vaccine awareness and factors affecting vaccination in Turkish Society.

Objective:Influenza vaccine reduces the burden of seasonal influenza and related complications. Potential vaccination barriers need to be identified to raise awareness and increase acceptance. We aimed to investigate the rates of seasonal influenza vaccination and the knowledge, opinions, and behaviours prevalent in Turkish society.Methods:The study among seven regions in Turkey was conducted from October-November 2018 in 28 family health centres, using a cross-sectional, descriptive design. The knowledge, opinions, and behaviours of participants regarding the influenza vaccine were obtained by family physicians through face-to-face interviews with participants.Results:A total of 3,492 people aged 10-97 years age range (median: 50 years) were included in the study. Over half of the participants (59.9%, n = 2093) were female. It was found that the percentage of participants who never received the influenza vaccine was 78.4%; only 13.4% were occasionally vaccinated, and 8.1% received regular annual vaccination. Influenza vaccination rates were higher in married people (p < 0.001), women (p = 0.005), patients with chronic lung and cardiovascular disease (p < 0.001), those over 65 years /nursing home residents (p < 0.001). Awareness of the vaccine’s benefit was higher in the group at high risk of influenza (p < 0.001).Conclusion:The rate of regular vaccination against influenza every year was insufficient, at 8.1%. Individuals’ insensitivity, insufficient knowledge, and attitudes toward influenza vaccination is a serious health problem for Turkish society. Barriers to influenza vaccination can be reduced by good communication between family physicians and their patients.

Association between a usual source of care and influenza vaccination rates among pregnant women.

Pregnant women and infants less than 6 months of age have a higher risk of complications from influenza. Vaccination is recommended for pregnant women to decrease risk of infection and hospitalizations between both the women themselves and infants. However, vaccination rates remain low in pregnant women. The objective of this study was to determine the association between having a usual source of care and seasonal influenza vaccination rates among women who were pregnant between 2012 and 2016. A retrospective study was conducted using pooled data from the 2012-2016 Medical Expenditure Panel Survey. Frequencies of seasonal influenza vaccinations and other sociodemographic factors were estimated. A multivariable log-binomial regression model was used to examine the association between having a usual source of care and seasonal influenza vaccination rates. The weighted influenza vaccination rate among pregnant women was 54.5%. About one third did not have a usual source of care. The adjusted prevalence ratio of receiving an influenza vaccine for pregnant women without a usual source of care was 0.76 (95% confidence interval=0.60-0.98). The top three main reasons for not having a usual source of care were being seldom or never sick (55.7%), not having health insurance (10.6%), and having recently moved to an area (9.9%). Pregnant women without a usual source of care had significantly lower probability of being vaccinated against seasonal influenza. Improving access to care through greater insurance coverage, addressing cost barriers, and providing patient education may help improve vaccination rates in this population.

Perception of Health Care Worker about Uptake of Influenza Vaccine in COVID-19 Era

Background: Considering the important role of health workers in increasing seasonal influenza vaccination coverage and the similarity of seasonal influenza to COVID -19, it is important to increase vaccination rates to reduce the risk of both diseases.&#x0D; Objective: In this study, we aim to investigate how health workers perceive the importance of influenza vaccination, especially in the era of COVID -19.&#x0D; Results: The study involved 316 health workers from Abha in 2021, most of them were physicians, male and young. Participants agreed that influenza can be a serious illness and that the vaccine is very safe. Most HCWs would have preferred to inform their patients about the vaccine. This result changes if the patient disagrees with the COVID -19 vaccine.&#x0D; Conclusion: Despite the low rate of seasonal influenza vaccination, there is a need to recruit health workers to increase this rate, especially in the Covid 19 era.

Improving influenza vaccination coverage at the University Medical Centre Ljubljana with workplace health promotion project

Seasonal influenza vaccination is one of the keys to preventing the spread of this disease. The seasonal influenza vaccination rate is very low for the general Slovenian population (the average rate from the 2015/16 season to the 2019/20 season is 4.3%) and also for healthcare employees (between 2009 and 2019, the average vaccination rate among healthcare workers in Slovenia was 12.9%), and it does not ensure sufficient community protection from the disease. At the beginning of the 2016/17 season, the University Medical Centre Ljubljana (UMCL) launched its first-ever occupational health promotion project with the slogan “I don’t pass on the flu! I get vaccinated to protect myself and others.” The goal of the project was to reach as many employees as possible and increase the general vaccination rate because those working in healthcare have a significantly greater risk of catching influenza than the rest of the working population. By being vaccinated, they protect not only themselves and their families against the disease, but also their patients. The project encouraged all employees to receive the free vaccination, especially those groups that had had lower vaccination rates over the past years. The support of the institution’s executive staff and the heads of individual divisions was key to securing the required funds and suitable conditions for carrying out the project. Different communication tools were used in the project. The promotion strategy increased vaccination coverage at the UMCL from under 10.0% to 13.9% in 2016, 20.9% in 2017, 21.7% in 2018, and 30.1% in 2019. Workplace health promotion can make a difference. The examples of good practice have made a substantial difference and will be taken into account in planning and organizing vaccination activities during future influenza seasons. This practical model can be used in other hospital settings as well.

Structural inequities in seasonal influenza vaccination rates

BackgroundInfluenza immunization is a highly effective method of reducing illness, hospitalization and mortality from this disease. However, influenza vaccination rates in the U.S. remain below public health targets and persistent structural inequities reduce the likelihood that Black, American Indian and Alaska Native, Latina/o, Asian groups, and populations of low socioeconomic status will receive the influenza vaccine.MethodsWe analyzed correlates of influenza vaccination rates using the 2019 Behavioral Risk Factor Surveillance System (BRFSS) in the year 2020. Our analysis compared influenza vaccination as the outcome of interest with the variables age, sex, race, education, income, geographic location, health insurance status, access to primary care, history of delaying care due to cost, and comorbidities such as: asthma, cardiovascular disease, hypertension, body mass index, cancer and diabetes.ResultsNon-Hispanic White (46.5%) and Asian (44.1%) participants are more likely to receive the influenza vaccine compared to Non-Hispanic Black (36.7%), Hispanic (33.9%), American Indian/Alaskan Native (36.6%), and Native Hawaiian/Other Pacific Islander (37.9%) participants. We found persistent structural inequities that predict influenza vaccination, within and across racial and ethnic groups, including not having health insurance [OR: 0.51 (0.47–0.55)], not having regular access to primary care [OR: 0.50 (0.48–0.52)], and the need to delay medical care due to cost [OR: 0.75 (0.71–0.79)].ConclusionAs COVID-19 vaccination efforts evolve, it is important for physicians and policymakers to identify the structural impediments to equitable U.S. influenza vaccination so that future vaccination campaigns are not impeded by these barriers to immunization.

Association between asthma and influenza vaccine uptake among US adolescents: a retrospective survey study

Objective Despite longstanding recommendations for children with asthma to receive the influenza vaccine, vaccine uptake in this population remains low. We used the nationally representative National Immunization Survey-Teen to analyze the impact of asthma on adolescent influenza vaccination rates. Methods Adolescents ages 13–17 years with provider-reported data on vaccine coverage were included in the analysis. The primary outcome was being up-to-date on influenza vaccination, defined as receiving the seasonal influenza vaccine in at least one of the past 3 years, and was analyzed using logistic regression. Asthma was defined by parent report of whether the adolescent has ever been told by a health professional that he or she has asthma. Data were collected in 2016–2017 and analyzed in 2020. Results Of 36,655 adolescents in the analytic sample (mean age 15 years, 49% female), 55% were up-to-date on influenza vaccination, and 21% had been diagnosed with asthma. On bivariate analysis, vaccination was more common among adolescents who had been diagnosed with asthma compared to those who were not (60% vs. 53%, P < 0.001). On multivariable analysis, asthma diagnosis was associated with greater likelihood of being up-to-date on seasonal influenza vaccination (adjusted odds ratio: 1.29; 95% confidence interval: 1.22, 1.36; P < 0.001). Conclusions Seasonal influenza vaccination rates remain low among adolescents. Despite concerns about vaccine effectiveness in children with asthma, this diagnosis was associated with increased likelihood of influenza vaccination, possibly in relation to increased health care use (and exposure to vaccine encouragement) among adolescents with asthma.

Impfen gegen Influenza – Internationale Bestandsaufnahme und Perspektiven für Deutschland

BackgroundThe current SARS-CoV-2 pandemic requires high influenza vaccination rates for the chronically ill in order to avoid additional strain on the health care system. Despite clear evidence of the safety and effectiveness of influenza vaccination, vaccination coverage has internationally remained at inadequate levels in recent years. The general practitioner is of central importance for the care of this population. Therefore, the aim of this systematic review was to evaluate various measures in general practice to increase seasonal influenza vaccination rates for the chronically ill, taking into account various international health systems. MethodsA systematic literature search was carried out in MEDLINE, CENTRAL, EMBASE and ERIC as well as manually in trial registers and literature lists. Only randomized controlled studies were taken into account. The methodology was defined in advance in a study protocol and published (PROSPERO CRD42018114163). ResultsA total of 14 studies within the framework of a national health service (United Kingdom), a state (Australia) and social (Switzerland) health insurance system and a private health care system (USA) were included in our review. Analog patient reminders and automated physician reminders as well as changes in professional roles have led to a significant increase in influenza vaccination rates, but only in the private health care system. In the national health service, none of the interventions we analyzed achieved a significant increase in vaccination rates, although the National Health Service in the United Kingdom documented relatively good basic influenza vaccination rates before the studies were carried out, regardless of the intervention. Good results were achieved in the social and state health insurance systems of Switzerland and Australia by training events for practice teams and SMS reminders. ConclusionsIn Germany, training events for medical teams and centrally organized invitation and monitoring systems might improve vaccination rates among the chronically ill. That the federal government pays for the vaccination costs seems to ensure a good basic influenza vaccination coverage for indicated patients in various health systems.

Seasonal Influenza Vaccine in Pregnant Women: Views and Experiences of Obstetrician-Gynecologists.

Background: Seasonal influenza vaccination rates among pregnant women remain well below the Healthy People 2020 target of 80%. Obstetrician-gynecologist (OB/GYN) recommendations are a critical means of encouraging pregnant women to get vaccinated, but there are limited data about their views. Materials and Methods: A nationally representative survey of 506 practicing OB/GYNs was completed between October 26, 2015, and May 8, 2016. Analyses included univariate distributions and comparisons based on age, size of practice, and academic affiliation using all-pairs, dependent t-tests. Results: A majority of OB/GYNs report they "strongly recommend" seasonal influenza vaccination for their pregnant patients in the first (79%) or second and third trimesters (81%). Among those who do not strongly recommend the flu vaccine in the first trimester, many say this is because of their own concerns (28%) or their patients' concerns (44%) about safety. Older OB/GYNs, those in smaller practices, and those without academic affiliation were less likely to recommend the vaccine and more likely to have safety concerns. For example, 72% of those age 60+ strongly recommended the vaccine in the second and third trimester, compared with 86% of those ages 30-44 and 83% of those ages 45-59 (p < 0.05 for all comparisons). Conclusions: OB/GYNs across the country largely support seasonal flu vaccination among pregnant women. Nonetheless, safety is a concern for them and their patients. Outreach to support clinician decisions and conversations with pregnant patients may be most needed among older physicians, those in smaller practices, and those without academic affiliation.
