Attitudes and perceptions among the pediatric health care providers toward influenza vaccination in Qatar: A cross-sectional study

Attitudes, motivators, and barriers toward influenza vaccination for children: a study from a conflict-ridden country

BACKGROUND

Despite the increased recommendations for influenza vaccination, particularly among high-risk groups such as young children, Yemen lacks an influenza vaccination program, and the influenza vaccine is not included in the national immunization regime. This is exacerbated by the country's fragile infrastructure, as well as the devastating consequences of the ongoing conflict, which include child undernutrition and strained healthcare resources. Thus, the objective of the current study is to assess the public attitudes and perceptions toward vaccinating children against influenza in Yemen.

METHODS

A cross-sectional study was conducted by distributing a validated survey questionnaire to potential participants using convenience sampling. Descriptive statistics were used to summarize sociodemographic data, knowledge of influenza vaccines, and attitudes and perceptions regarding vaccinating children against influenza. Logistic regression analysis was employed to identify associations between independent variables and the acceptance of vaccines for children.

RESULTS

A total of 853 eligible individuals, parents and non-parents, successfully completed the survey. The uptake of the influenza vaccine among the participants was notably low as the majority (69.2%) had not previously received the vaccine, although the majority expressed a willingness to get vaccinated in the future (59.4%). The majority (68.5%) were willing to vaccinate children. The largest percentage of the participants who expressed hesitancy toward children's vaccination cited multiple reasons to reject the vaccine (39.7%), with concerns regarding the safety of the vaccine being the predominant barrier to its acceptance for children (29.6%). On the other hand, motivating factors for vaccinating children included the validation of the vaccine's safety and efficacy, endorsement of the vaccine by the government and physicians, integration of the vaccine into the national immunization program, and the provision of the vaccine free of charge and through schools. Significant predictors for vaccine acceptance in children included male gender, knowledge of the protective effect of the influenza vaccine, previous receipt of the vaccine, and a willingness to receive the vaccine in the future.

CONCLUSIONS

The study highlights the need for educational health campaigns to raise awareness and remove misconceptions regarding influenza and the role, benefits, and availability of its vaccine. These findings can serve as a robust foundation for the future design and implementation of an influenza vaccination program for children in Yemen.

Motivators and barriers of seasonal influenza vaccination among primary health care physicians in Qatar

Annual influenza vaccination is an effective way to reduce the burden of disease throughout the year. A cross-sectional study was conducted in primary healthcare centres in Qatar to determine vaccination coverage among physicians, motivators, and barriers. The vaccination rate was higher among physicians aged 45 years and above (p-value < 0.005). Most primary care physicians (95 %) strongly agree that being vaccinated reduces the risk of disease spread. The most frequently mentioned barriers were the belief that one could still get influenza after being vaccinated and the fear of side effects (92.6 % and 29.5 %, respectively). Health authorities can implement strategies that take these factors into account to increase immunization coverage.

Influenza vaccination rates among healthcare workers: a systematic review and meta-analysis investigating influencing factors

Introduction

Healthcare workers risk of exposure to the influenza virus in their work, is a high-risk group for flu infections. Thus WHO recommends prioritizing flu vaccination for them-an approach adopted by >40 countries and/or regions worldwide.

Methods

Cross-sectional studies on influenza vaccination rates among healthcare workers were collected from PubMed, EMBASE, CNKI, and CBM databases from inception to February 26, 2023. Influenza vaccination rates and relevant data for multiple logistic regression analysis, such as odds ratios (OR) and 95% confidence intervals (CI), were extracted.

Results

A total of 92 studies comprising 125 vaccination data points from 26 countries were included in the analysis. The meta-analysis revealed that the overall vaccination rate among healthcare workers was 41.7%. Further analysis indicated that the vaccination rate was 46.9% or 35.6% in low income or high income countries. Vaccination rates in the Americas, the Middle East, Oceania, Europe, Asia, and Africa were 67.1, 51.3, 48.7, 42.5, 28.5, and 6.5%, respectively. Influencing factors were age, length of service, education, department, occupation, awareness of the risk of influenza, and/or vaccines.

Conclusion

The global influenza vaccination rate among healthcare workers is low, and comprehensive measures are needed to promote influenza vaccination among this population.

Influenza Prevalence and Vaccine Efficacy among Diabetic Patients in Qatar

Seasonal influenza viruses may lead to severe illness and mortality in patients with comorbidities, including Diabetes Mellitus (DM). Vaccination against influenza in DM patients may reduce influenza incidence and severity. Before the emergence of the COVID-19 pandemic, influenza infections were the most prevalent respiratory infections in Qatar. Still, reports about influenza prevalence and vaccine efficacy in DM patients have not been reported. This study aimed to analyze influenza prevalence among other respiratory infections and assess influenza vaccine efficacy in DM patients in Qatar. Statistical analysis was performed on data obtained from Hamad Medical Corporation (HMC) database for patients that visited the emergency department (ED) with respiratory-like illnesses. The analysis was done for the period between January 2016 to December 2018. Among 17,525 patients who visited HMC-ED with clinical symptoms of respiratory infections, 2611(14.9%) were reported to have DM. Among DM patients, influenza was the most prevalent respiratory pathogen at 48.9%. Influenza virus A (IVA) was the most circulating type, contributing to 38.4%, followed by IVB contributing to 10.4% of total respiratory infections. Among the typed IVA-positive cases, 33.4% were H1N1, and 7.7% were H3N2. A significant decrease in influenza infections was reported in vaccinated DM patients (14.5%) when compared to non-vaccinated patients (18.9%) (p-value = 0.006). However, there was no significant relaxation in the clinical symptoms among vaccinated DM patients compared to their non-vaccinated counterparts. In conclusion, influenza was the most common etiology for respiratory viral infection among diabetic patients at the leading healthcare provider in Qatar. Although vaccination reduced the incidence rate among DM patients, it was less effective in preventing symptoms. Further studies on a larger cohort and for a more extended period are required to investigate influenza prevalence and vaccine efficacy among DM patients.

Beliefs and Sociodemographic and Occupational Factors Associated with Vaccine Hesitancy among Health Workers

Introduction: Vaccine hesitancy has been implicated in the low-vaccination coverage in several countries. Knowledge about vaccine hesitancy predictors in health workers is essential because they play a central role in communication about the importance and safety of vaccines. This study aimed to assess beliefs and sociodemographic and occupational factors associated with vaccine hesitancy in health workers. Methods: This was a cross-sectional study among 453 health workers in primary and medium complexity services in a municipality in the state of Bahia, Brazil. The variable vaccine hesitancy was operationalized based on the answers related to incomplete vaccination against hepatitis B, measles, mumps and rubella, and diphtheria and tetanus. Associations between variables were expressed as prevalence ratios (PR) and their respective 95% confidence intervals (CI). Results: Endemic disease combat agents, administrative service workers, and support staff had the highest levels of vaccine hesitancy. Among the analyzed variables, the following were associated with vaccine hesitancy: working in secondary health care services (PR: 1.21; CI: 1.07-1.36), working as an endemic disease combat agent (PR = 1.42; 95% CI: 1.165-1.75), not sharing information about vaccines on social media (PR = 1.16; 95% CI: 1.05-1.28), distrusting information about vaccinations (PR: 0.86; CI: 0.75-0.99), and not feeling safe receiving new vaccines (PR = 1.16; 95% CI: 1.06-1.28). Conclusions: Strategies to enhance confidence in vaccination among health workers should consider differences in occupations and their working settings. Improving vaccination-related content in training and continuing education activities and facilitating access to onsite vaccinations at the workplace are crucial elements to reduce vaccine hesitancy among health workers.

Differences and disparities in seasonal influenza vaccine, acceptance, adverse reactions, and coverage by age, sex, gender, and race

BACKGROUND

Influenza is a significant threat to public health worldwide. Despite the widespread availability of effective and generally safe vaccines, the acceptance and coverage of influenza vaccines are significantly lower than recommended. Sociodemographic variables are known to be potential predictors of differential influenza vaccine uptake and outcomes.

OBJECTIVES

This review aims to (1) identify how sociodemographic characteristics such as age, sex, gender, and race may influence seasonal influenza vaccine acceptance and coverage; and (2) evaluate the role of these sociodemographic characteristics in differential adverse reactions among vaccinated individuals.

METHODS

PubMed was used as the database to search for published literature in three thematic areas related to the seasonal influenza vaccine - vaccine acceptance, adverse reactions, and vaccine coverage.

RESULTS

A total of 3249 articles published between 2010 and 2020 were screened and reviewed, of which 39 studies were included in this literature review. By the three thematic areas, 17 studies assessed vaccine acceptance, 8 studies focused on adverse reactions, and 14 examined coverage of the seasonal influenza vaccine. There were also two studies that focused on more than one of the areas of interest.

CONCLUSION

Each of the four sociodemographic predictors - age, sex, race, and gender - were found to significantly influence vaccine acceptance, receipt and outcomes in this review.

A comprehensive review of drivers influencing flu vaccine acceptance in the Middle East over the last six years: using Health Belief Model

OBJECTIVES

The objectives of this study were to review the literature covering the perceptions about influenza vaccines in the Middle East and to determine factors influencing the acceptance of vaccination using Health Belief Model (HBM).

METHODS

A comprehensive literature search was performed utilizing PubMed and Google Scholar databases. Three keywords were used: Influenza vaccine, perceptions and Middle East. Empirical studies that dealt with people/healthcare worker (HCW) perceptions of influenza vaccine in the Middle East and written in English were included. The search covered articles published between January 2015 and November 2020.

KEY FINDINGS

A total of 34 cross-sectional studies covering a total of 35 518 participants from 22 countries were included in this review. The overall influenza vaccination rates were generally low (<50%) among general population, particularly among pregnant women and children. HCWs had relatively higher vaccination rates compared with general population. Old age, health comorbidities or working in high-risk environments were noted as major motivators to receive the vaccine. Concerns about adverse reactions and the lack of vaccine efficacy were the most predominant reported barriers to receiving the vaccines. Lastly, cues to actions included receiving advice from HCWs, influence of institutional requirement, awareness/educational pamphlets and influence from the media.

SUMMARY

The HBM can be helpful in identifying and analysing motivators and barriers to vaccination. Additionally, by looking at the root causation, this model can help plan campaigns to increase vaccination rates in the region. Finally, we recommend empowering HCWs to proactively advocate for vaccination as part of preventive care.

Determinants of seasonal influenza vaccination hesitancy among healthcare personnel: An integrative review

AIMS AND OBJECTIVES

To explore the determinants of and behaviour change models for seasonal influenza vaccination compliance among healthcare personnel.

BACKGROUND

COVID-19 vaccine hesitancy among healthcare personnel may be better understood by exploring determinants of seasonal influenza vaccine hesitancy.

DESIGN

Integrative literature review.

METHODS

A systematic search was conducted in accordance with PRISMA guidelines. Six thousand and forty-eight articles were screened. Seventy-eight met inclusion criteria. Due to the heterogeneity of included articles, a narrative synthesis was conducted utilising a conceptual matrix to identify thematic categories.

RESULTS

Six thematic categories were identified as influencing HCP SIV compliance: 'perceived vulnerability', 'trust', 'past behaviour', 'professional duty', 'access and convenience' and 'knowledge and experience'. The Health Belief Model (HBM) was the most commonly utilised health behaviour change model within the seasonal influenza vaccination context. Few studies have examined seasonal influenza vaccine acceptance and uptake within the Australian HCP context, particularly involving community care and aged care.

CONCLUSIONS

Factors that appear to relate to influenza vaccination compliance among HCP can be grouped according to several thematic categories, and they also appear influential in COVID-19 vaccine uptake. In particular, an emerging focus on 'trust' or the more emotive considerations of decision-making around health-protective behaviours requires further exploration in the context of a pandemic. Efforts to influence these domains to increase compliance, however, are likely to be impeded by a lack of a well-developed and tested behaviour change model.

RELEVANCE TO CLINICAL PRACTICE

Healthcare personnel (HCP) face high levels of occupational exposure to seasonal influenza every year. An emerging focus on 'trust' and the more emotive considerations of decision-making around health-protective behaviours requires further exploration in the context of a pandemic.

Uptake rates, knowledge, attitudes, and practices toward seasonal influenza vaccination among healthcare workers in Lebanon

Despite recommendations and their occupational risk to influenza infection vaccine hesitancy remains a challenge among healthcare workers (HCWs). No studies have been conducted in Lebanon to assess the influenza vaccine's acceptance among HCWs. We conducted a survey to assess factors associated with vaccine uptake and practices among HCWs in Lebanon. Only 40.4% of the HCWs reported receiving the 2018-2019 seasonal vaccine and 1 out 5 routinely received the seasonal vaccine. One-third of the HCWs reported having free access to the influenza vaccine. The willingness to receive the vaccine decreased had it been offered for a fee. Self, family and community protection (55.5%) was a key vaccination enabler. While, viral evolution, concerns regarding vaccine efficacy and side effects, and cost of vaccine ranked as top vaccination barriers. The majority of the HCWs (75%) recommended the vaccine to their patients. Past influenza vaccination (Odds ratio (OR) = 2.37, CI 1.48,3.79), willingness to receive the vaccine for free (OR = 6.93, CI 4.27-11.34) or having diagnosed influenza (OR = 1.81, CI 1.12-2.92) were significantly associated with HCWs' willingness to recommend the vaccine to patients. Better knowledge about influenza and vaccination was strongly associated with the willingness to receive and recommend the vaccine (p < .001). The vaccination rate among HCWs in Lebanon was suboptimal despite the positive attitudes toward the influenza vaccine. Interventions that enhance vaccine accessibility and knowledge are warranted to improve vaccination coverage among HCWs.

COVID-19 vaccine hesitancy and attitudes in Qatar: A national cross-sectional survey of a migrant-majority population

Background

Vaccine hesitancy is a global threat undermining control of preventable infections. Emerging evidence suggests that hesitancy to COVID‐19 vaccination varies globally. Qatar has a unique population with around 90% of the population being economic migrants, and the degree and determinants of hesitancy are not known.

Methods

This study was carried out to evaluate the degree of vaccine hesitancy and its socio‐demographic and attitudinal determinants across a representative sample. A national cross‐sectional study using validated hesitancy measurement tool was carried out from October 15, 2020, to November 15, 2020. A total of 7821 adults completed the survey. Relevant socio‐demographic data along with attitudes and beliefs around COVID‐19 vaccination were collected from the respondents.

Results

20.2% of the respondents stated they would not take the vaccine and 19.8% reported being unsure about taking the prospective COVID‐19 vaccine. Citizens and females were more likely to be vaccine hesitators than immigrants and males, respectively. Concerns around the safety of COVID‐19 vaccine and its longer‐term side effects were the main concerns cited. Personal research around COVID‐19 and vaccine were by far the most preferred methods that would increase confidence in accepting the vaccine across all demographic groups.

Conclusions

This study reports an overall vaccine hesitancy of 20% toward the COVID‐19 vaccine and the influence of social media on attitudes toward vaccination which is in keeping with emerging evidence. This finding comes at a time that is close to the start of mass immunization and reports from a migrant‐majority population highlighting important socio‐demographic determinants around vaccine hesitancy.

Review of seasonal influenza vaccination in the Eastern Mediterranean Region: Policies, use and barriers

Vaccination is the main control measure for influenza and its severe complications. To better understand the influenza vaccination situation in the Eastern Mediterranean Region, we conducted an extensive review of literature published between 2006 and 2016 in the region on influenza vaccine policies, use, recommendations and coverage. Forty-eight articles met the inclusion criteria. These originated from 11 of the 22 countries of the region, with most being from Saudi Arabia and Iran. The review revealed knowledge gaps and misconceptions about influenza and its vaccines even among healthcare workers. Most of the papers reviewed reported low coverage in the target populations. Limited literature on the number of countries with concrete national influenza vaccination policies was available, which may not accurately represent the situation in the Region. In conclusion, lack of awareness and knowledge are the main barriers to influenza vaccination, which remains very low in the Eastern Mediterranean Region. Countries of the region need to promote and invest in research on influenza vaccination, which is critical to inform evidence-based programmes and policies to improve vaccination rates and control influenza.

Seasonal influenza vaccination among primary health care workers in Southwestern Saudi Arabia

Background: Vaccination of primary healthcare workers (PHCWs) help to prevent the spread of influenza among at-risk patients.Objectives: To assesses seasonal influenza vaccination (SIV) coverage and the factors affecting SIV's utilization among PHCWs in Abha city, southwestern Saudi Arabia.Methods: A cross-sectional survey was carried out between June 2018 and August 2018 in all primary healthcare centers in Abha city. It targeted physicians, nurses, technicians, and pharmacists. A self-administered questionnaire was used to collect data regarding SIV status during the 2017-2018 season, obtain knowledge regarding SIV and influenza disease, and identify potential motivators for and barriers to SIV.Results: Of 312 PHCWs, the SIV coverage rate was 45.5% in the 2017-2018 vaccination season. A multivariable logistic regression model showed that the risk groups for non-vaccination were PHCWs less than 40 years old (adjusted Odds Ratio (aOR) = 4.07, 95% CI: 1.50-11.03), technicians (aOR = 3.73, 95% CI: 1.20-11.54), single PHCWs (aOR = 2.36, 95% CI:1.20-4.62), and PHCWs lacking adequate influenza vaccine knowledge (aOR = 4.22, 95% CI: 2.13-8.35). Approximately 23% and 32% of PHCWs were found to have inadequate knowledge about SIV and influenza disease, respectively. PHCWs' awareness about their risk of infection and their need for protection was found to be the most common motivator (77.5%), and a fear of side effects was found to be the most frequent barrier (40%).Conclusion: SIV coverage rate is suboptimal. Knowledge gaps and misconceptions about the influenza vaccine are the main barriers to an adequate coverage.

Knowledge, attitudes and practices related to influenza illness and vaccination in children: Role of awareness campaigns in changing parents' attitudes toward influenza vaccination in Jordan

BACKGROUND

Influenza infection is associated with a significant health burden in children, especially in developing countries. The influenza vaccine is an important preventive strategy for flu illness. Aim of this study to assess knowledge, attitudes and practices (KAP) related to influenza illness and vaccination in children in the Jordanian population and to study the effect of awareness campaigns on changing the attitudes of parents toward vaccinating their children against influenza.

METHODS

A cross-sectional study was conducted among families visiting shopping malls and parks in November 2016. A questionnaire was administered via in-person interviews. Answers to KAP questions regarding influenza illness and vaccination were summed, with a total KAP score of 30. Facts about influenza illness and vaccination were explained to parents and provided in printed pamphlets.

RESULTS

There were 1241 respondents. 10.9% of participants had vaccinated their children during the last season 2015/2016. The mean KAP score (standard deviation) was 16.21 (4.61). People living in urban areas, with high monthly income >600 JD and healthcare workers had higher KAP scores than their counterparts. Compared to other sources of information about the influenza vaccine, health resources correlated most with vaccinating children. Awareness and educational pamphlets changed attitudes positively in 29% of parents who refused the influenza vaccine for their children.

CONCLUSIONS

Awareness about influenza illness and vaccination is insufficient, and the coverage rate of influenza vaccination in children is low in the Jordanian population. Implementing public health policies is necessary to spread knowledge about influenza illness and vaccination and to promote the practice of receiving the influenza vaccine in children. Educational campaigns are helpful in changing the attitudes of parents toward vaccinating their children against the flu.

[Vaccination and associated factors among health workers]

This study aimed to analyze factors associated with vaccination of municipal health workers in Bahia State, Brazil. This was a cross-sectional study from 2010 and 2012 with 3,084 workers in primary and medium-complexity care. The following indicators were described: prevalence of vaccination in the adult calendar according to the Brazilian National Immunization Program (PNI) and the completeness of vaccination regimens according to sociodemographic, economic, work, domestic overload, psychosocial, satisfaction and social support at work, occupational, life habits, health status, and self-rated health variables. Multivariate analysis was performed to assess the joint effect of the study variables. Only 38.5% of the workers reported complete vaccinal status for all the vaccines in the adult calendar. Completeness of the vaccination card showed a positive association with: female gender (95%CI: 1.42-2.10), working directly in patient care (95%CI: 1.26-1.71), having technical resources for the development of the professional activities (95%CI: 1.02-1.34), social support at work (95%CI: 1.02-1.26), contact with biological material (95%CI: 1.39-1.75), preparation of medications (95%CI: 1.10-1.44), and positive self-rated health (95%CI: 1.03-1.41). Factors such as sociodemographic conditions and occupational exposure have an influence on vaccination. Given the resurgence of immune-preventable diseases, it is necessary to monitor health workers' vaccinal status. The phenomenon should be analyzed according to its complexity, focusing on aspects related to resistance that extrapolate the issues usually measured and allow the investigation of beliefs attributed to vaccines.

Factors influencing seasonal influenza vaccination uptake among health care workers in an adult tertiary care hospital in Singapore: A cross-sectional survey

BACKGROUND

This study aimed to evaluate the factors influencing seasonal influenza vaccination uptake among different health care professional groups.

METHODS

A single-center, cross-sectional survey using a standardized anonymous, self-administered questionnaire to assess knowledge, attitudes, and uptake of seasonal influenza vaccination was used. Associations between respective health care groups and vaccination acceptance were then assessed.

RESULTS

In total, 3,873 health care workers completed the questionnaire. Of these, 7% were administrative staff, 17% were allied health staff, 7% were ancillary staff, 11% were medical staff, and 58% were nursing staff. The overall vaccination rate for the Southern Hemisphere 2015 influenza season was 82%. In a multivariate logistic regression model, after controlling for gender and presence of chronic disease, associated factors for accepting influenza vaccination were age, education level of bachelor degree or higher, preference for vaccination provided by mobile teams, having 1-50 patient contacts per week, and belief in the potential severity of influenza and vaccine safety (P < .05). In contrast, factors negatively associated with vaccination acceptance included being a medical staff member or allied health staff member, living with family members under the age of 16, fear of adverse reactions, and disbelief in vaccination effectiveness (P < .05).

CONCLUSIONS

Although vaccine coverage in Singapore has been high, our findings provide guidance for the development of strategies to further improve vaccine coverage among different groups of health care workers.

Knowledge, attitude, and practice of influenza vaccine immunization among primary healthcare providers in Dubai health authority, 2016-2017

Background: Vaccination of healthcare providers (HCPs) against seasonal influenza has been consistently recommended worldwide. Despite that, healthcare providers (HCPs) globally and in other Middle Eastern countries continue to have a low rate of influenza vaccination due to various reasons. No data are available from our country, United Arab Emirates. Objectives: To identify the percentage of vaccinated HCPs, identify the most common reason for receiving the vaccine or not and to identify the level of HCPs knowledge towards the influenza vaccine itself. Methods: Using a cross-sectional study design, anonymous 18-item self-administered questionnaires were distributed among healthcare providers in the 11 primary healthcare centers of Dubai Health Authority over a period of 5 months. Results: Of the 431 participants who completed the questionnaires, 53.4% reported getting vaccinated. The difference in the vaccine uptake between the different professional categories was significant [P value < .000].The most common reason reported by HCPs for getting the vaccine was to protect themselves (94.8%). Of the 46.6% who did not accept the vaccine, the most common reason for not being vaccinated was their belief of not being at high risk to contract influenza (39.8%). Despite fairly good knowledge (63.3%), healthcare providers continue to have their reservations with regards to the yearly influenza vaccination. Conclusion: Although our HCPs attitude towards vaccine uptake, knowledge and practice were positive; the misconception about the vaccine remains the main reason for not being vaccinated as per our study findings. Overall, the study results raise hope of prospective increase in vaccination through educational and technical interventions and by increasing physician involvement. One suggested method would be to apply mandatory vaccination policies since voluntary vaccinations have shown lesser than satisfactory results and to be integrated in the online staff file system to be able to verify the uptake, in addition to provide easily accessible vaccine centers, during the season in order to facilitate tracking and verification of the vaccination status & to encourage staff compliance.

Why do we not want to recommend influenza vaccination to young children? A qualitative study of Australian parents and primary care providers

INTRODUCTION

Influenza vaccination has been shown to be safe and effective against influenza and in the prevention of complicating secondary respiratory illnesses. However, its uptake in young children remains low. This study explored the views, attitudes and practices of parents and primary care providers (PCPs) on their knowledge and acceptance of influenza vaccination in children under 5.

METHODS

Using a cross-sectional qualitative research design, we conducted 30 in-depth interviews with PCPs (i.e., general practitioners, practice nurses, maternal and child health nurses, and pharmacists) and five focus groups with parents (n = 50) between June 2014 and July 2015 in Melbourne, Australia. Data were thematically analysed.

RESULTS

Parents thought the vaccine could cause influenza, and influenza vaccination was not necessary for their children as they needed to build their own 'immunity'. Parents said that they would consider vaccinating their children if recommended by their GP and if the influenza vaccine was part of the immunisation schedule. PCPs also expressed concerns regarding the efficacy of the vaccine as well as out-of-pocket costs incurred by families, and uncertainty regarding the mortality and morbidity of influenza in otherwise healthy children. However, they said they would recommend the vaccine to high-risk groups (e.g. children with chronic disease(s), and asthma).

CONCLUSION

Despite the established safety of influenza vaccines, barriers to uptake include concerns regarding the iatrogenic effects of vaccination, its administration schedule, and knowledge of influenza severity. Updated information on influenza and the efficacy of the vaccine, and incorporating influenza vaccination into the immunisation schedule may overcome some of these barriers to increase influenza vaccination in this vulnerable cohort.

Improving Influenza Vaccination Rate among Primary Healthcare Workers in Qatar

The purpose of this study was to improve influenza vaccination, and determine factors influencing vaccine declination among health care workers (HCW) in Qatar. We launched an influenza vaccination campaign to vaccinate around 4700 HCW in 22 Primary Health Care Corporation (PHCC) centers in Qatar between 1st and 15th of November, 2015. Our target was to vaccinate 60% of all HCW. Vaccine was offered free of charge at all centers, and information about the campaign and the importance of influenza vaccination was provided to employees through direct communication, emails, and social media networks. Staff were reported as vaccinated or non-vaccinated using a declination form that included their occupation, place of work and reasons for declining the vaccine. Survey responses were summarized as proportional outcomes. We exceeded our goal, and vaccinated 77% of the target population. Only 9% declined to take the vaccine, and the remaining 14% were either on leave or had already been vaccinated. Vaccine uptake was highest among aides (98.1%), followed by technicians (95.2%), and was lowest amongst pharmacists (73.2%), preceded by physicians (84%). Of those that declined the vaccine, 34% provided no reason, 18% declined it due to behavioral issues, and 21% declined it due to medical reasons. Uptake of influenza vaccine significantly increased during the 2015 immunization campaign. This is attributed to good planning, preparation, a high level of communication, and providing awareness and training to HCW with proper supervision and monitoring.

Individual background factors associated with vaccination for seasonal influenza in Japanese schoolchildren

There is little evidence about how individual background factors affect seasonal influenza vaccination of children. At the end of the 2014/2015 influenza season, a cross-sectional questionnaire survey of all elementary schoolchildren in 29 schools in Matsumoto City, Japan, was conducted to obtain information about vaccine uptake activity and individual background factors. Of the 10,524 subjects who responded, 5063 (48.1%) had been vaccinated. Grade in school, underlying disease, number of siblings, and diagnosis with and vaccination for influenza during the previous influenza season differed significantly in vaccinated and unvaccinated groups. Multivariate logistic regression showed that underlying disease and vaccination during the previous influenza season was associated with a higher rate of vaccination, whereas higher grade in school and having ≥3 siblings was associated with a lower rate of vaccination. The findings may be useful to promote a vaccination policy recommending financial support to households with many children or to encourage higher uptake of vaccination in higher grade children.

An assessment of healthcare professionals' knowledge about and attitude towards influenza vaccination in Freetown Sierra Leone: a cross-sectional study

Background

Vaccinating healthcare professionals against influenza is considered an effective infection control measure. However, there is a low uptake of influenza vaccine among healthcare professionals around the globe. Currently, it is unknown whether healthcare professionals in Sierra Leone are aware of, and have been vaccinated against influenza. Also, there is a paucity of research evidence on their level of knowledge and attitude toward influenza vaccination. This study assessed healthcare professionals’ current influenza vaccine uptake rate, reasons for not getting vaccinated as well as their awareness, knowledge of, and attitude towards influenza vaccination in Freetown Sierra Leone.

Method

A cross-sectional study was conducted between February and April 2016 among healthcare providers working in four public and two private health facilities in Freetown Sierra Leone. Linear regression analysis, one-way ANOVA and independent t-test were employed for data analysis.

Results

Among 706 respondents that participated in the study more than half were females 378 (53.6%), nurses 425 (60.4%), and the majority were between the age group of 20-39 years 600 (85.3%). Only 46 (6.5%) were vaccinated against influenza. Key reasons for not vaccinated against influenza were less awareness about influenza vaccination among HCPs 580 (82.73%) with (β = 0.154; CI 0.058–0.163), the high cost of influenza vaccines and therefore not normally purchased 392 (55.92%) having (β = 0.150; CI 0.063–0.186). More than half believed that HCPs are less susceptible to influenza infections than other people. Also, majority 585 (84.3%) of HCPs thought that influenza disease could be transmitted after symptoms appear. In addition, 579 (83.2%) of HCPs felt that symptoms usually appear 8–10 days after exposure. Close to half 321 (46.0%) of HCPs were not aware of the influenza immunisation guidelines published by the Advisory Committee on Immunization Practices and Centre for Disease Control.

Conclusion

Influenza vaccine coverage among healthcare professionals in Freetown Sierra Leone was low. High cost, inadequate knowledge about influenza and its vaccine as well as the lack of awareness of vaccine availability were key barriers. Increasing access to influenza vaccine and the use of appropriate educational interventions to increase knowledge and awareness are required to improve influenza vaccination coverage among HCPs.

Vaccinations against respiratory infections in Arabian Gulf countries: Barriers and motivators

AIM

To study the uptake, barriers and motivators of influenza, pneumococcal, meningococcal and pertussis vaccines among members of public in Arabian Gulf countries.

METHODS

A cross-sectional survey among the Gulf Cooperation Council (GCC) countries’ residents. Data collected electronically through a smartphone app. The survey variables aimed to investigate the respondents’ awareness about vaccines against influenza, pneumococcal, meningococcal and pertussis infections. Collected data concerning the respondents’ socio-demographic characteristics, their perception toward vaccine uptake and the factors that motivate or demotivate them from taking influenza vaccine. The data were analysed statistically using the SPSS v.23.0. Differences in the characteristics of users from different countries were quantified through bivariate analysis. Other important variables and controlling factors were studied using logistic regression.

RESULTS

A total of 1812 respondents participated in the study. Their mean age was 27 years, 82% were male and 24% had ≥ 1 chronic diseases. The overall uptake of influenza vaccine was 17% (21% among “at risk” people) and ranged from 15% in Saudi Arabia to 24% in Qatar. Doctor’s advice (23%) and a perception of having low body immunity (21%) were the main cited reasons for being vaccinated, whereas unawareness about the vaccine (43%) was the main barrier. The overall uptake of pneumococcal vaccine in the preceding three years was 22% (25% among “at risk” individuals) and ranged from 0% in Bahrain to 79% in Kuwait. The overall uptake of pertussis vaccine was 16% (31% among “vulnerable” people), and ranged from 7% in Saudi Arabia to 75% in Oman. The overall uptake of meningococcal vaccine was 20% (29% among the “at risk” people) and ranged from 3% in Oman to 50% in Bahrain.

CONCLUSION

The vaccination uptake across GCC countries is suboptimal and varies widely across the countries. Further research is needed to unearth the reasons and formulate action plan.

Barriers of Influenza Vaccination Intention and Behavior - A Systematic Review of Influenza Vaccine Hesitancy, 2005 - 2016

BACKGROUND

Influenza vaccine hesitancy is a significant threat to global efforts to reduce the burden of seasonal and pandemic influenza. Potential barriers of influenza vaccination need to be identified to inform interventions to raise awareness, influenza vaccine acceptance and uptake.

OBJECTIVE

This review aims to (1) identify relevant studies and extract individual barriers of seasonal and pandemic influenza vaccination for risk groups and the general public; and (2) map knowledge gaps in understanding influenza vaccine hesitancy to derive directions for further research and inform interventions in this area.

METHODS

Thirteen databases covering the areas of Medicine, Bioscience, Psychology, Sociology and Public Health were searched for peer-reviewed articles published between the years 2005 and 2016. Following the PRISMA approach, 470 articles were selected and analyzed for significant barriers to influenza vaccine uptake or intention. The barriers for different risk groups and flu types were clustered according to a conceptual framework based on the Theory of Planned Behavior and discussed using the 4C model of reasons for non-vaccination.

RESULTS

Most studies were conducted in the American and European region. Health care personnel (HCP) and the general public were the most studied populations, while parental decisions for children at high risk were under-represented. This study also identifies understudied concepts. A lack of confidence, inconvenience, calculation and complacency were identified to different extents as barriers to influenza vaccine uptake in risk groups.

CONCLUSION

Many different psychological, contextual, sociodemographic and physical barriers that are specific to certain risk groups were identified. While most sociodemographic and physical variables may be significantly related to influenza vaccine hesitancy, they cannot be used to explain its emergence or intensity. Psychological determinants were meaningfully related to uptake and should therefore be measured in a valid and comparable way. A compendium of measurements for future use is suggested as supporting information.

Who benefits most from influenza vaccination policy: a study among the elderly in Beijing, China

Background

Influenza continues to have a major impact on vulnerable populations worldwide, particularly among the elderly (≥60 years of age). Vaccination for targeted groups is recommended by the WHO as the most effective way to control influenza infections. Since 2009, the Beijing municipal government has provided influenza vaccination to the elderly at no out-of-pocket cost to reduce influenza threats and improve related health equality. The study aims to evaluate the equality of the policy, and to analyze factors that bring influences to equality.

Methods

Based on data from a household survey, concentration index (CI) was calculated to measure the socioeconomic inequality in influenza vaccination. A Logit regression model was used to decompose CI, in which the contribution of each determinant was calculated and the percentages of these contribution were obtained.

Results

Free influenza vaccination at point of use shows significant pro-poor distribution among the elderly in Beijing (CI = −0.115). After the decomposition of CI, the elderly with lower income, higher education, and living in rural areas were more likely to get the influenza vaccination, in which place of residence (contribution percentage = 57 %) held the most contribution of variance.

Conclusions

Beijing’s free influenza vaccination strategy at point of use could provide the poor elderly with equal opportunities to receive preventive health service, showing a significant pro-poor distribution. The poor elderly, who live in rural areas with high education, benefit most from the policy. Further policy interventions should target the population living in urban areas in order to improve the utilization of public health services and health equality.
