A systematic review and meta-analysis. Hum Vaccin Immunother 2024; 20:2300848. [PMID: 38174706 PMCID: PMC10773666 DOI: 10.1080/21645515.2023.2300848] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Accepted: 12/27/2023] [Indexed: 01/05/2024] Open
Abstract
This review quantified the association of vaccine literacy (VL) and vaccination intention and status. PubMed, Scopus, and Web of Science were searched. Any study, published until December 2022, that investigated the associations of interest were eligible. For each outcome, articles were grouped according to the vaccine administrated and results were narratively synthesized. Inverse-variance random-effect models were used to compare standardized mean values in VL domain(s) between the two groups: individuals willing vs. unwilling to get vaccinated, and individuals vaccinated vs. unvaccinated. This review of 18 studies shows that VL strongly predicts the vaccination intention while its association with vaccination status is attenuated and barely significant, suggesting that other factors influence the actual vaccination uptake. However, given the scarce evidence available, the heterogeneity in the methods applied and some limitations of the studies included, further research should be conducted to confirm the role of VL in the vaccination decision-making process.

Achore M. Correlates of COVID-19 vaccine uptake among the forcibly displaced: evidence from Libya. Arch Public Health 2024; 82:70. [PMID: 38741160 DOI: 10.1186/s13690-024-01306-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 05/04/2024] [Indexed: 05/16/2024] Open
Abstract
BACKGROUND Vaccine hesitancy and refusal can hinder the control of infectious diseases such as coronavirus disease 2019 (COVID-19). Although forcibly displaced individuals are at high risk of contracting COVID-19, evidence shows that they are less likely to accept the COVID-19 vaccine. Given their predicament, the factors influencing vaccine uptake in the general population might differ vastly from those in displaced populations. Given the limited evidence on vaccine uptake from humanitarian settings, the current study examined the determinants of COVID-19 vaccine uptake among the forcibly displaced in Libya. METHODS Data were extracted from the World Bank/United Nations High Commissioner for Refugees (UNHCR) microdata repository. Data were collected between April and July 2021 after the rollout of the first dose of the COVID-19 vaccine in Libya. Percentages, means, and standard deviations were used to quantify the distribution of the sample population. Logistic regression models were employed to identify factors influencing COVID-19 vaccine uptake. RESULTS Odds ratios (ORs) with p values are used to present the regression analysis results. The study revealed that people unaffected by COVID-19 were less likely (OR = .71, 95%CI = 0.67-0.89) to accept the vaccine. Similarly, individuals with access to free COVID-19 vaccines were more likely to be vaccinated than those without free vaccines (OR = 38, 95%CI = 0.19-0.28). Finally, the results indicated that individuals were six times more likely to be vaccinated at mass vaccination sites ((OR = 6.31, 95%CI = 5.46- 7.94) and 1.92 times more likely to be vaccinated at local health centers (OR = 1.92, 95%CI = 0.1.72-3.11) than they were at hospitals and distant health facilities. CONCLUSION Implementing comprehensive mass vaccination venues, public education initiatives, and awareness campaigns regarding the importance of vaccination can decrease vaccine hesitancy among the forcibly displaced.

BMC Public Health 2024; 24:924. [PMID: 38553696 PMCID: PMC10981287 DOI: 10.1186/s12889-024-18372-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 03/17/2024] [Indexed: 04/01/2024] Open
Abstract
BACKGROUND Influenza vaccination is recommended for those at increased risk of influenza complications and their household contacts to help reduce influenza exposure. Adults who require care often experience health issues that could increase the risk of severe influenza and have close contact with caregivers. Assessing influenza vaccination prevalence in caregivers and care recipients can provide important information about uptake. OBJECTIVES We aimed to (1) estimate influenza non-vaccination prevalence and (2) assess factors associated with non-vaccination among caregivers aged ≥ 45 years and among care recipients aged ≥ 65 years. METHODS We conducted an analysis of cross-sectional data from the Canadian Longitudinal Study on Aging collected 2015-2018. We estimated non-vaccination prevalence and reported adjusted odds ratios with 95% confidence intervals from logistic regression models to identify factors associated with non-vaccination among caregivers and care recipients. RESULTS Of the 23,500 CLSA participants who reported providing care, 41.4% (95% CI: 40.8%, 42.0%) reported not receiving influenza vaccine in the previous 12 months. Among the 5,559 participants who reported receiving professional or non-professional care, 24.8% (95% CI: 23.7%, 26.0%) reported not receiving influenza vaccine during the same period. For both groups, the odds of non-vaccination were higher for those who had not visited a family doctor in the past year, were daily smokers, and those who identified as non-white. DISCUSSION Identifying groups at high risk of severe influenza and their close contacts can inform public health efforts to reduce the risk of influenza. Our results suggest sub-optimal influenza vaccination uptake among caregivers and care recipients. Efforts are needed to increase influenza vaccination and highlight the direct and indirect benefits for caregiver-care recipient pairs. CONCLUSION The proportions of both caregivers and care recipients who had not been vaccinated for influenza was high, despite the benefits of vaccination. Influenza vaccination campaigns could target undervaccinated, high-risk groups to increase coverage.

Abstract
Background/Purpose The COVID-19 outbreak created unique policy challenges for vaccinating special groups like migrants. As part of sustainable development goals, the equitable distribution of the COVID-19 vaccine can contribute to ensuring health for all. This study examined COVID-19 vaccine uptake among foreign migrants in China based on sociodemographics, cultural beliefs, past vaccine behaviors, and psychosocial factors. Design An online cross-sectional survey was conducted among foreign migrants in mainland China via social media platforms from 21 November through 20 December 2021. Bivariate (unadjusted odd-ratio) and multivariate logistic regression analyses were performed to establish the correlates of COVID-19 vaccine uptake. Result Surveyed foreign migrants that are culture neutral (AOR: 2.5, CI: 95%, 1.02-5.90, p = 0.044), willing to pay for vaccination (AOR: 2.27, CI: 95%, 1.18-3.98, p = 0.012), believe in vaccine efficacy (AOR: 3.00, CI: 95%, 1.75-5.16, p < 0.000), have poor psychological health (AOR: 1.96, CI: 95%, 1.14-3.38, p = 0 0.014), and have higher perceived seriousness of COVID-19 (AOR: 2.12, CI: 95%, 1.26-3.57, p = 0.005) are more likely to receive COVID-19 vaccine. Those migrants with a history of declining vaccination (AOR: 0.34, CI: 95%, 0.18-0.65, p = 0.000) and middle-income earners $1701-3500 (AOR: 0.43, CI: 95%, 0.23-0.82, p = 0.010) are less likely to receive the COVID-19 vaccine. Conclusion This study brings a unique perspective to understanding vaccine behavior among international migrants in China. There is an urgent call from the World Health Organization and countries for complete vaccination and efforts to improve vaccine coverage. However, fewer studies have been conducted globally on the vaccination of migrant populations. The current study provides empirical information to increase the knowledge of the correlates of vaccine behavior among immigrants in countries around the globe. Future studies should conduct cross-country comparisons to understand the factors associated with increasing vaccination rates among immigrant populations to formulate a strong policy to increase vaccine coverage among immigrant populations across countries.

[PMID: 36220715 DOI: 10.1016/j.vaccine.2022.09.061] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 08/26/2022] [Accepted: 09/19/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND Although more than half of older adults receive the annual influenza vaccine (flu shot), only about one-third have ever been vaccinated for shingles. With this in mind, our study examines how the associations between sociodemographic characteristics, health behaviors, and vaccine uptake differ between these two viruses. In doing so, it also investigates whether the social predictors of shingles vaccination changed after the rollout of a new vaccine in 2017. METHODS Data come from the 2017 and 2020 waves of the Behavioral Risk Factor Surveillance System survey, using a subset of older adults aged 60-plus (N = 389,165). We use logistic regression models to test for associations between individual-level characteristics and vaccine uptake. RESULTS One, when compared to Whites, Black respondents had approximately 30 % lower odds of having received the annual influenza vaccine (Odds Ratios [OR] = 0.72 [95 % CI 0.66-0.78] in 2017, and 0.66 [0.60-0.72] in 2020). For the shingles vaccine, these racial differences were starker (OR = 0.53 [0.48-0.59] in 2017, and OR = 0.55 [0.49-0.60] in 2020). Two, self-rated health was negatively associated with having received the influenza vaccine, but showed little relationship with shingles vaccination. Three, men were less likely than women to receive both vaccines in 2020 (OR = 0.88 [0.83-0.94] for influenza, and OR = 0.80 [0.75-0.85] for shingles). Four, older adults who abstained from alcohol were, generally, less likely to receive either vaccine, when compared to both moderate and heavy drinkers. Finally, we found that the release of a new shingles vaccine in 2017 (Shingrix) had little effect on vaccination prevalence or its social determinants. CONCLUSION The importance of social groups, health, and health behaviors on vaccination status may be disease-dependent. This study also provides possible guidance to health care providers and health organizations looking to increase vaccine uptake among older adults, which may have more urgency since the arrival of COVID-19.

Abstract
BACKGROUND Despite the importance of influenza vaccination, its rates in subjects with asthma are suboptimal, especially in the young population. METHODS Among 72,843 adults aged ⩾18 years from the Korea National Health and Nutrition Examination Survey conducted between 2010 and 2019, 1643 with asthma were included. The yearly trends and factors associated with influenza vaccination were analyzed in subjects with asthma. In addition, stratified analyses were performed by age group (<65 versus ⩾65 years). RESULTS During the study period, the overall influenza vaccination rate among subjects with asthma fluctuated from 51.0% to 64.3%, with a consistently higher vaccination rate in elderly subjects than in young subjects. Among young subjects with asthma, factors positively associated with influenza vaccination were female sex [adjusted odds ratio (aOR) = 1.66, 95% confidence interval (CI) = 1.11-2.49], current asthma being treated (aOR = 1.69, 95% CI = 1.14-2.50), history of pulmonary tuberculosis (aOR = 2.01, 95% CI = 1.04-3.87), and dyslipidemia (aOR = 1.86, 95% CI = 1.05-3.30). However, unmarried subjects showed an inverse relationship (aOR = 0.50, 95% CI = 0.34-0.75). In elderly subjects, unmarried status (aOR = 0.52, 95% CI = 0.29-0.94), being underweight (aOR = 0.29, 95% CI = 0.09-0.97), and having a low income (aOR = 0.42, 95% CI = 0.18-0.97) were factors negatively associated with influenza vaccination. CONCLUSION In the last 10 years, influenza vaccination rates have still been insufficient in subjects with asthma, particularly in young subjects. Considering the factors that are influencing the vaccination rates of young subjects, public policies to increase influenza vaccination rates in subjects with asthma need to be established urgently.

Influenza vaccine coverage and factors associated with non-vaccination among adults at high risk for severe outcomes: An analysis of the Canadian Longitudinal Study on Aging. PLoS One 2022; 17:e0275135. [PMID: 36178943 PMCID: PMC9524702 DOI: 10.1371/journal.pone.0275135] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 09/09/2022] [Indexed: 11/21/2022] Open
Abstract
Background Influenza vaccination is recommended in Canada for older adults and those with underlying health conditions due to their increased risk of severe outcomes. Further research is needed to identify who within these groups is not receiving influenza vaccine to identify opportunities to increase coverage. Objectives We aimed to 1) estimate influenza non-vaccination prevalence and 2) assess factors associated with non-vaccination among Canadian adults aged ≥65 and adults aged 46–64 with ≥1 chronic medical condition (CMC) due to their high risk of severe influenza outcomes. Methods We conducted a secondary analysis of cross-sectional data collected from 2015–2018 among participants of the Canadian Longitudinal Study on Aging. For both groups of interest, we estimated non-vaccination prevalence and used logistic regression models to identify factors associated with non-vaccination. We report adjusted odds ratios and 95% confidence intervals for the investigated variables. Results Overall, 29.5% (95% CI: 28.9%, 30.1%) of the 23,226 participants aged ≥65 years and 50.4% (95% CI: 49.4%, 51.3%) of the 11,250 participants aged 46–64 years with ≥1 CMC reported not receiving an influenza vaccination in the past 12 months. For both groups, lack of recent contact with a family doctor and current smoking were independently associated with non-vaccination. Discussion Influenza vaccination helps prevent severe influenza outcomes. Yet, half of adults aged 46–64 years with ≥1 CMC and more than one-quarter of all adults aged ≥65 years did not receive a recommended influenza vaccine in the year prior to the survey. Innovation in vaccination campaigns for routinely recommended vaccines, especially among those without annual family doctor visits, may improve coverage. Conclusion Influenza vaccination coverage among Canadian adults aged 46–64 years with ≥1 CMC and adults aged ≥65 years remains suboptimal. Vaccination campaigns targeting those at high risk of severe outcomes without routine physician engagement should be evaluated to improve uptake.

Abstract
Reaching a high vaccination coverage level is of vital essence when preventing epidemic diseases. For mandatory vaccines, the demand can be forecasted using some demographics such as birth rates or populations between certain ages. However, it has been difficult to forecast non-mandatory vaccine demands because of vaccine hesitation, alongside other factors such as social norms, literacy rate, or healthcare infrastructure. Consequently, the purpose of this study is to explore the predominant factors that affect the non-mandatory vaccine demand, focusing on the recommended childhood vaccines, which are usually excluded from national immunization programs. For this study, fifty-nine factors were determined and categorized as system-oriented and human-oriented factors. After a focus group study conducted with ten experts, seven system-oriented and eight human-oriented factors were determined. To reveal the cause and effect relationship between factors, one of the multi-criteria decision-making methods called Fuzzy-DEMATEL was implemented. The results of the analysis showed that “Immunization-related beliefs”, “Media/social media contents/messaging”, and “Social, cultural, religious norms” have a strong influence on non-mandatory childhood vaccine demand. Furthermore, whereas “Availability and access to health care facilities” and “Political/ financial support to health systems” are identified as cause group factors, “Quality of vaccine and service delivery management” is considered an effect group factor. Lastly, a guide was generated for decision-makers to help their forecasting process of non-mandatory vaccine demands to avoid vaccine waste or shortage.

Abstract
OBJECTIVE Only about one-third of older adults in the United States are vaccinated against shingles, contributing to approximately one million shingles cases annually. This study examines how sociodemographic characteristics, health behaviors, and self-rated health are associated with shingles vaccine uptake. METHOD Data come from the 2017 wave of the Behavioral Risk Factor Surveillance System survey, using a subset of older adults aged 60-plus (N=208,301). Logistic regression models test (1) for associations between individual-level sociodemographic characteristics and vaccine uptake and (2) whether health behaviors and self-rated health moderate these associations. RESULTS Black and Hispanic older adults have almost 50% lower odds of shingles vaccination, compared to non-Hispanic Whites. Abstaining from alcohol, being employed, living with children, and having poor self-rated health are also associated with lower uptake. Unmarried (vs. married) individuals have lower odds of vaccination that are explained by broad differences in health behavior. DISCUSSION Our study contributes to understanding how shingles vaccination coverage systematically differs among social groups. In doing so, it provides guidance for public health interventions to increase uptake. This line of research is increasingly salient in a world facing novel virus threats and anti-vaccine social movements.

Abstract
The aims of this cross-sectional survey were to evaluate the knowledge, attitudes, and self-reported adherence to recommended vaccinations among a random sample of patients with chronic conditions presenting for a medical visit in out-patient clinics in Italy. Patients who were healthcare workers (HCWs), those with diabetes, those who had received information by Internet, physicians, and friends/relatives, and those who needed more information were more likely to know that the influenza vaccine is recommended for patients with chronic diseases. More than half (58.2%) and 8.9% self-reported to have received at least one recommended vaccination and more than one, respectively. Patients who believed that vaccine-preventable diseases (VPDs) were dangerous for them, those who had received information by physicians, and those who needed information were more likely to have received at least one recommended vaccination. This behavior was less likely in married patients, those who were worried about the side effects of the vaccines, and those who suffered from renal failure. The results highlight the need to implement effective vaccination programs in order to decrease the complication of VPDs in at-risk population.

Asthma is considered one of the most common noncommunicable diseases worldwide, with an incidence of 5.4% in the Polish, adult population. Symptoms of the disease can be triggered or worsened by a variety of factors including viral infection such as influenza, affirming the necessity for prophylactic vaccination. However, there is concern among the general population of the possibility of anaphylactic response to vaccination, which can deter patients with allergic asthma for fear of triggering exacerbation of their condition. The objective of the study was to determine the extent to which patients with asthma adhere to a schedule of recommended vaccinations in Poland. Two hundred fourteen patients were recruited from specialist outpatient clinics in Warsaw to complete voluntarily an anonymous questionnaire created for the purpose of this study. Within the past year, 82% stated having at least one respiratory infection, and 72% of patients were aware of the recommendation for annual vaccination against the flu. Forty-three percent of patients reported receiving the flu vaccine at least once, and only 20% followed through with annual vaccination. The most common sources of information about the importance of annual flu vaccination were from their doctors (47%) and the media (26%). Relatively few asthmatic patients in Warsaw get annual flu vaccinations despite the recommendations. These results were mainly sourced due to uncorrected fears and a lack of information about the importance of prophylaxis in asthma. It is essential to create effective strategies to inform patients with asthma of the importance of annual vaccinations.

Abstract
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.

Napolitano F, Della Polla G, Angelillo IF. Knowledge, Attitudes, and Behaviors of Parents towards Recommended Adult Vaccinations: An Explanatory Survey in the Geographic Area of Naples, Italy. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16122070. [PMID: 31212739 PMCID: PMC6616468 DOI: 10.3390/ijerph16122070] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Revised: 06/01/2019] [Accepted: 06/08/2019] [Indexed: 12/11/2022]
Abstract
The purposes of this study were to explore the knowledge, attitudes, and behaviors towards the recommended vaccinations for adults between 19–64 years of age and the associated factors among parents. The survey was conducted from October to December 2018 among a sample of parents randomly selected from five preschools and primary, secondary, and high schools in the geographic area of Naples, Italy. The mean age of participants was 45.2 years (range 19–71). Only 16% of the parents knew all vaccinations recommended to adults between 19–64 years of age. Those being healthcare professionals, having a chronic condition, having received information about vaccinations from physicians, and having a lower educational level were more likely to know the vaccinations recommended to adults between 19–64 years of age. Female participants, those who had received information about vaccinations from physicians, and those who had a lower number of children were more likely to have a positive attitude toward the usefulness of the administration of vaccinations recommended to adults between 19–64 years of age. Among unvaccinated respondents, more than half reported a positive attitude toward willingness to receive a recommended vaccination. This positive attitude was significantly higher among those who considered vaccinations as being useful and among who had received information from physicians. Only 16.9% self-reported to have received at least one vaccination recommended to adults between 19–64 years of age. Those who were healthcare professionals, who had at least one chronic condition, and who considered the administration of the vaccinations as being useful were more likely to have received at least one recommended vaccination. Greater efforts by policy makers and healthcare providers are needed to increase parents’ knowledge on recommended vaccines, and it is also crucial that healthcare providers have a high knowledge and favorable attitudes in order to increase vaccine coverage.

CANADIAN JOURNAL OF PUBLIC HEALTH = REVUE CANADIENNE DE SANTE PUBLIQUE 2018; 109:369-378. [PMID: 29981075 PMCID: PMC6153712 DOI: 10.17269/s41997-018-0018-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Accepted: 11/18/2017] [Indexed: 11/26/2022]
Abstract
OBJECTIVES The study objectives were to (1) identify determinants of non-vaccination against seasonal influenza in Canadian adults and (2) examine self-reported reasons for non-vaccination. METHODS The data source was the 2015-2016 Influenza Immunization Coverage Survey, a national telephone survey of Canadian adults. Participants (n = 1950) were divided into three groups: adults aged 18-64 years with (n = 408) and without (n = 1028) chronic medical conditions (CMC) and adults ≥ 65 years (n = 514). Logistic regression was used to measure associations between sociodemographic factors and non-vaccination for the 2015-2016 influenza season. Weighted proportions were calculated to determine the main self-reported reasons for not receiving the influenza vaccine. RESULTS Younger age was found to be associated with non-vaccination across all groups. In adults ≥ 65 years, elementary- or secondary- vs. university-level education (aOR 1.87, 95% CI 1.14-3.06) was also significantly associated with non-vaccination. Significant variation in vaccine uptake was found for several sociodemographic factors in adults aged 18-64 without CMC. Low perceived susceptibility or severity of influenza and lack of belief in the vaccine's effectiveness were the most commonly reported reasons for not receiving the vaccine. CONCLUSION In general, our results were consistent with findings from other Canadian and American studies on seasonal influenza vaccine uptake. Belief that the influenza vaccine is not needed was common, even among those at increased risk of influenza-related complications. Additional research is needed to better understand how sociodemographic factors such as income and education may influence uptake and to raise awareness of potential complications from influenza infection in high-risk adults.
