Better knowledge and regular vaccination practices correlate well with higher seasonal influenza vaccine uptake in people at risk: Promising survey results from a university outpatient clinic

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.

Trust in Physicians in the Context of HPV Vaccination of Children from the Perspective of Social Exchange Theory: A Representative Study of Polish Parents

The vaccination of children against human papillomavirus (HPV) effectively prevents HPV infection and HPV-related cancers in women and men. However, HPV vaccination programs are met with vaccine hesitancy, which varies between countries. The coverage in Poland is low, although introducing nationally funded HPV vaccination for girls aged 12-13 in mid-2023 may increase it. The uptake of the HPV vaccine in adolescents is highly affected by parental decisions, which in turn can be influenced by interactions with the physician. The present representative study aimed to analyze the acceptance of the HPV vaccine among Polish parents (n = 360) and the level of trust in HPV vaccination in the pediatrician/general practitioner who takes care of their children aged 9-15 years. The data were gathered in September 2022 using computer-assisted telephone interviews. Most surveyed parents reported trusting their child's physician regarding vaccine recommendations (89.2%) and vaccinated their child with all or most of the vaccines recommended by a national vaccination guideline (94.7%). However, 13.3% declared themselves as moderate or strong vaccine opponents, a group characterized by high (83.4%) distrust in physicians. There was no difference in the awareness of HPV in groups varying in trusting the physicians, but parents who trusted them were more frequently aware of the HPV vaccine. Parental willingness to vaccinate their child against HPV was highly differentiated by the level of trust in the child's physician. The results highlight that trust in physicians is a critical factor shaping decisions for children's vaccination, stressing a continuous need to improve strategies to communicate with patients.

The Influence of Recommendation of Medical and Non-Medical Authorities on the Decision to Vaccinate against Influenza from a Social Vaccinology Perspective: Cross-Sectional, Representative Study of Polish Society

Vaccination against seasonal flu is crucial to prevention of illness in modern societies. The level of influenza vaccination in Poland is low and, for many years, has hovered around a few percent of the general population. For this reason, it is crucial to understand the reasons for such a low level of vaccination and to assess the influence of medical and social authorities on the decision to vaccinate against influenza from the perspective of social vaccinology. For this purpose, a representative survey was conducted in 2022 among adult Poles (N = 805), orchestrated with the CAWI technique based on the author's questionnaire. The most significant authority in the context of influenza vaccination is held by physicians, especially among the oldest part of the population, over 65 years of age-in this group, 50.4% of respondents declare a very high level of respect for physicians on the issue of recommended influenza vaccination (p < 0.001), and the second-highest authority group for which seniors have respect in the aspect of influenza vaccination is pharmacists (p = 0.011). It was also shown that pharmacists have more authority on the issue of influenza vaccination than nurses, especially in the group that declared themselves opponents of vaccination (p < 0.001). The survey indicates the need to strengthen the authority of physicians and pharmacists regarding influenza vaccination, and, in the case of pharmacists, the need for changing the law to allow them to qualify for influenza vaccination.

Nursing Interventions Increase Influenza Vaccination Quality Measures for Home Telehealth Patients

BACKGROUND

Influenza vaccinations are a preventive health quality measure. Home telehealth nursing staff interventions can reduce influenza disease burden and complications.

PURPOSE

To improve seasonal flu vaccine rates using novel home telehealth clinical and technology interventions.

METHODS

A pre- and postintervention concurrent cohort study for 513 outpatients was conducted. Interventions included automated 2-way patient messaging using remote monitoring equipment, a new note template to record vaccination status in the electronic health record, and flu vaccine patient education.

RESULTS

Interventions resulted in vaccination rates of 70.4% for Veterans ages 19 to 65 years, and 81.7% for Veterans 66 years and older, exceeding national, regional, and local Veterans Administration targets.

CONCLUSIONS

Two-way messaging and standardized documentation increased rates. Declinations persisted despite education. Reasons included fear of side effects, and rarely leaving home due to the COVID-19 pandemic. Nursing interventions can increase influenza vaccination quality measures for primary care home telehealth patients.

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.

Should vaccination be mandated? Individuals' perceptions on mandatory vaccination in Greece

OBJECTIVES

The aim of this study was to explore factors that influence individuals' attitudes towards mandatory vaccination in Greece.

METHODS

A nationally representative cross-sectional telephone survey was conducted via a random multistage selection process in October 2019 in Greece. The survey was designed to obtain information about whether vaccination should be mandated or not among adults 18 years of age or older. A multivariable logistic regression model was used to estimate the association between individuals' sociodemographic, contextual and clinical characteristics, utilization, satisfaction, and trust in the healthcare system and providers and their preference over mandatory vaccination.

RESULTS

A total of 901 participants fully completed the survey (response rate 90%-901/1001). About 85% of the respondents supported mandatory vaccination. Individuals who used preventive services more often compared to those who never or rarely used such, those who reported increased trust in official healthcare authorities' guidelines and recommendations compared to those who reported no trust and those who had underage children living in the household were significantly more likely to support mandatory vaccination. No differences were observed for sociodemographic factors and mandatory vaccination support.

CONCLUSION

This survey revealed that most Greek citizens support mandatory vaccination, which was critically affected by the utilization of preventive services and trust in healthcare authorities. Our results suggest that healthcare policy interventions should promote mandatory vaccination through multi-level initiatives to improve healthcare providers' and the general public's understanding of the value of vaccination.

Determinants of influenza vaccine uptake and willingness to be vaccinated by pharmacists among the active adult population in Hungary: a cross-sectional exploratory study

Background

Many studies have addressed influenza vaccine uptake in risk-group populations (e.g. the elderly). However, it is also necessary to assess influenza vaccine uptake in the active adult population, since they are considered to be a high-transmitter group. In several countries pharmacists are involved in adult vaccination in order to increase uptake. This study therefore aimed to investigate the determinants of influenza vaccination uptake and examine the willingness to be vaccinated by pharmacists.

Methods

A cross-sectional study was conducted among Hungarian adults using a self-administered online questionnaire distributed via social media (Facebook). The questionnaire included five domains: demographics, vaccine uptake, factors that motivated or discouraged vaccination, knowledge and willingness of participants to accept pharmacists as influenza vaccine administrators. Descriptive statistics were applied and logistic regression was conducted to assess the possible determinants of vaccination uptake.

Results

Data from 1631 participants who completed the questionnaires were analysed. Almost 58% of respondents (944/1631) had occupational and/or health risk factors for influenza. Just over one-tenth (12.3%;200/1631) of participants were vaccinated during the 2017/18 influenza season, 15.4% (145/944) of whom had a risk factor for influenza. Approximately half of the participants (47.4%) believed that influenza vaccination can cause flu, and just over half of them (51.6%), were not knowledgeable about the safety of influenza vaccine ingredients. Logistic regression found that age, sex, health risk factor and knowledge on influenza/influenza vaccination were associated with influenza vaccination uptake (p < 0.05). The most frequently cited reason for having an influenza vaccination was self-protection (95.0%). The most common reason given for refusing the influenza vaccine was that the respondent stated they rarely had an infectious disease (67.7%). The number of participants who were willing to be vaccinated by pharmacists was two-times higher than the number of participants who were actually vaccinated during the 2017/18 influenza season.

Conclusion

Influenza vaccine uptake in the active adult population is low in Hungary. Public awareness and knowledge about influenza vaccination and influenza disease should be increased. The results also suggest a need to extend the role played by pharmacists in Hungary.

Improving influenza and pneumococcal vaccination uptake among incident peritoneal dialysis patients: a quality improvement initiative

INTRODUCTION

Influenza and pneumococcal vaccination rates among peritoneal dialysis (PD) patients remain suboptimal, despite availability of vaccinations and health recommendations.

AIM

The primary aim was to improve influenza and pneumococcal vaccination rates among incident PD patients at our center to 80%. A secondary aim was to develop a sustainable workflow for vaccination in PD patients.

DESIGN

A quality improvement (QI) initiative to increase vaccination rate among incident PD patients was conducted in a tertiary care hospital in Singapore from Jul 2017 to Dec 2018. Key drivers and barriers to success were identified through root cause analysis. Change ideas focusing on improving opportunities, access and enhancement of reminder systems were implemented using Plan-Do-Study-Act methodology. Vaccination rates were monitored at 3-month intervals.

RESULTS

Total of 249 patients were eligible for vaccination. The baseline vaccination rate for influenza, pneumococcal conjugate vaccine (PCV13) and pneumococcal polysaccharide vaccine (PPSV23) were 63%, 54% and 14%, respectively. Root-cause analyses revealed several practice-related barriers, including lack of physician recommendation, time constraints and ineffective reminder systems. Multifaceted interventions, such as the provision of vaccination at non-traditional clinical settings, physician audit and feedback, utilisation of reminder tools, successfully increased influenza, PCV13 and PPSV23 vaccination rates to 86%, 85% and 63%, respectively.

CONCLUSION

A robust influenza and pneumococcal vaccination program implemented using a standardized QI methodology and multidisciplinary approach is effective in improving and sustaining influenza and pneumococcal vaccination uptake among PD patients.

Association between knowledge of influenza vaccine and vaccination status among general population attending primary health care centers in Al-Madinah, Saudi Arabia

Background:

Influenza vaccination is essential for population health. However, despite its strong recommendation, studies indicated a low rate of vaccine uptake. This study aimed to explore knowledge and attitudes towards influenza vaccinations among the general population attending primary health care centers in Al-Madinah, Saudi Arabia.

Materials and Methods:

This cross-sectional study was conducted among 381 participants from four health care centers in Al-Madinah city. A validated self-administered questionnaire was used. It includes questions on sociodemographic variables, knowledge, attitude, and vaccine uptake. Chi square test and simple logistic regression test were used to assess association between vaccination status and study variables.

Results:

Mean (SD) age of participant was 37 (12.5) and age ranged from 18 to 65 years. The majority were male (64.6%). Three out of seven items were answered correctly by most of the participants. The majority were classified as not knowledgeable (53.5%). More than half have been vaccinated with influenza vaccine (58.3%). Factors associated with vaccination uptake were Age group (P < 0.05), Marital status (P < 0.05), education level (P < 0.05) and Knowledge (P < 0.05).

Conclusion:

The study showed poor knowledge and attitude toward influenza vaccination among general population but a relatively accepted rate of vaccine uptake. Vaccination uptake was associated with knowledge, marital status, education, and age. This study recommends implementation of educational programs to increase the awareness among the general population.

Characteristics associated with human papillomavirus vaccination initiation and completion among young adults

BACKGROUND

Human papillomavirus (HPV) vaccination has been recommended for young adults aged 18-26 years.

METHODS

Data from the 2016 and 2017 National Health Interview Survey were pooled.

RESULTS

The prevalence of HPV vaccination initiation (≥1 dose) was 32.54% in 2016 and 37.92% in 2017, and the prevalence of HPV vaccination completion (≥3 doses) was 17.05% in 2016 and 19.38% in 2017 among young adults aged 18-26 years. Being female sex (odds ratio: 4.74) was the leading indicator for receiving the HPV vaccine, followed by receipt of other recommended vaccines (pneumococcal, hepatitis B, and hepatitis A), begin born in the United States, being gay/lesbian, having a greater number of physician visits, being younger, not being married, living in the Northeast, ever having had a pap smear, higher education, being not Hispanic ethnicity, and having more physical activity. Meanwhile, being female sex (odds ratio: 7.23) was the leading indicator for completing the HPV vaccination, followed by receipt of other recommended vaccines (pneumococcal, hepatitis B, and hepatitis A), having a greater number of physician visits, being younger, being born in the United States, being gay/lesbian, living in the Northeast, and current drinking.

CONCLUSIONS

HPV vaccination coverage remains low among young adults, and HPV vaccine coverage was associated with a number of characteristics.

Characteristics associated with hepatitis A vaccination initiation and completion among adults traveling to a country of high or intermediate endemicity

BACKGROUND

Hepatitis A (HepA) vaccine is recommended for adults traveling to a country of high or intermediate endemicity.

METHODS

The data from the 2016 and 2017 National Health Interview Survey were pooled in this analysis, and the weighted logistic regression model was adopted.

RESULTS

Characteristics independently associated with HepA vaccination initiation (≥1 dose) (in descending order by odds ratio) include age, receipt of pneumococcal and influenza vaccine, education, sexual orientation, region, number of physician visits in the past 12 months, physical activity, marital status, computer use, ratio of family income to the poverty threshold, Hispanic ethnicity, and class of worker. Characteristics independently associated with HepA vaccination completion (≥2 doses) (in descending order by odds ratio) include age, receipt of pneumococcal and influenza vaccine, sexual orientation, education, region, marital status, number of physician visits in the past 12 months, ratio of family income to the poverty threshold, physical activity, Hispanic ethnicity, and computer use.

CONCLUSIONS

HepA vaccination initiation and completion was associated with a number of characteristics, which can be used to develop strategies to increase HepA vaccination coverage among adults traveling to a country of high or intermediate endemicity.

Characteristics associated with hepatitis B vaccination initiation and completion among adults traveling to a country of high or intermediate endemicity

BACKGROUND

The hepatitis B (HepB) vaccine is recommended for adults traveling to a country of high or intermediate endemicity.

METHODS

Data from the 2016 and 2017 National Health Interview Surveys were pooled.

RESULTS

The weighted prevalence of HepB vaccination initiation (≥1 dose) was 37.67% in 2016 (weighted number: 30,581,813/81,192,803) and 40.20% in 2017 (weighted number: 34,509,993/85,849,427). The weighted prevalence of HepB vaccination completion (≥3 doses) was 29.97% in 2016 (weighted number: 24,331,218/81,192,803) and 31.78% in 2017 (weighted number: 27,282,536/ 85,849,427). Characteristics independently associated with HepB vaccination initiation (in descending order by odds ratio) included age, receipt of influenza vaccine, education, ever having lived with someone with hepatitis, class of worker, number of physician visits in the past 12 months, ratio of family income to the poverty threshold, region, sexual orientation, gender, heath insurance, computer use, physical activity, and Hispanic ethnicity. Similar results were found in the analysis for HepB vaccination completion, except that subjects born in the United States showed a higher likelihood of HepB vaccination completion.

CONCLUSIONS

HepB vaccination initiation and completion were associated with a number of characteristics that can be utilized to develop strategies to increase HepB vaccination coverage among adults traveling to a country of high or intermediate endemicity.

Knowledge Regarding Influenza and Influenza Vaccination in General Population: Results of a National Survey in Poland

For the past 10 years, influenza vaccination coverage rate in Poland remains at a low 3% threshold. This low rate may be related to the unsatisfactory knowledge of vaccination, influenza, and misperception of health risks in the general population. To examine these issues, we used an online questionnaire consisting of 12 closed questions. The basic knowledge on influenza and vaccination was examined. The questionnaire was completed by 1669 persons, mostly young women. Generally, 73% of respondents passed the threshold of 70% correct answers, but important gaps in their knowledge were identified concerning the persons at risk of developing the infection (7.9% of correct answers) and the timing of vaccination (8.4% of correct answers). Although most respondents did identify the etiologic agent correctly (91.1% knew influenza is caused by a virus), only 12.3% knew that the vaccines registered in Poland contain fragments of viruses or its antigens, while 63.1% thought the vaccines contain live bacteria. In conclusion, the knowledge on influenza vaccination is deficient in the general population. Education on immunization should be prioritized to increase vaccination coverage rate in Poland.

Understanding the unique characteristics of seasonal influenza illness to improve vaccine uptake in the US

Seasonal influenza results in substantial morbidity, mortality and socio-economic burden. The US Advisory Committee on Immunization Practices recommends vaccination of everyone over 6 months of age, but coverage remains substantially below the Healthy People 2020 target of 70% in most age groups. Influenza is different from other vaccine-preventable diseases in several ways that influence vaccine uptake. Although the incidence of most vaccine-preventable diseases is low, there is a perception that these diseases result in significant illness or death. In contrast, seasonal influenza has a relatively high incidence, but there is an incorrect perception of a lower disease severity. The vaccine effectiveness of seasonal influenza vaccines is less than other routine vaccines, varies from season to season between northern and southern hemispheres, and can be low in some seasons. It is also not well recognized that vaccination can attenuate the severity of influenza illness. Finally, the need for annual vaccination is perceived as a burden to busy people. Understanding these differences from the perspective of caregivers and vaccinees might help to improve influenza vaccine uptake. Presenting vaccine effectiveness in terms of clinical outcomes that have the most impact might help to overcome the perceptions that influenza is a non-serious disease and that the vaccine is not effective. The benefits of disease attenuation need to be emphasized in terms of reduced mortality, hospitalization, absenteeism and disruption to daily life. Innovative communication strategies should be adopted, including stronger recommendations from and to healthcare providers, continuous patient education, and social media initiatives employing more emotional and narrative approaches than traditionally used. Finally, access to seasonal influenza vaccination needs to be improved, and barriers such as cost and inconvenience removed. Multiple initiatives have already been successful. The remaining challenge is to translate individual successes into public health policies with corresponding funding and implementation.

Patient's behaviors and missed opportunities for vaccination against seasonal epidemic influenza and evaluation of their impact on patient's influenza vaccine uptake

Objectives

Influenza vaccination (IV) coverage remains low in France. Objectives were to assess patient knowledge and behaviors and missed opportunities for vaccination (MO) and their impact on vaccine uptake.

Methods

This is a prospective-observational study, including emergency department patients at risk for severe influenza. Patients were interviewed about their knowledge and behaviors. We evaluated the health-care voucher scheme (HCVS) and MO.

Results

868 patients were included. Vaccine uptake was 33.2%, 42% of patients knew about the possible severity of influenza, 23% thought that they were not at risk for severe influenza, 39% knew that they have an indication for the vaccine, and 4.3% to 11.5% expressed reservations concerning IV side effects and effectiveness. HCVS was used by 44.3% of patients, but only 14.8% had been vaccinated. MO were reported by 484 patients (69.4%) declaring 1104 consultations and 148 IV propositions (86.6%). Predictors of vaccine uptake (p<0.0001) were: knowledge of serious and fatal influenza forms [OR 0.36 (CI95% 0.25–0.5)]; confidence in influenza vaccine effectiveness [0.38 (0.2–0.7)]; opposition to vaccines [0.22 (0.1–0.48)]; visit to general practitioner [4.53 (2.9–7.1)]; general practitioner proposed IV [2.1 (1.2–3.4)].

Conclusion

Our results indicate that high rate of missed opportunities, some patient behaviors and general practitioner visits may explain low influenza vaccine uptake, and that HCVS use is a complex process. Of interest, we found that the patient’s knowledge of the potential severity of influenza is not sufficient to promote vaccine, suggesting that the information strategy must be adapted to each patient behavior.
