Havelka EM, Sanfilippo JE, Juneau PL, Sherman G, Cooper D, Leggio L. The effect of alcohol, tobacco, and other drug use on vaccine acceptance, uptake, and adherence: a systematic review. Alcohol Alcohol 2024; 59:agae057. [PMID: 39371015 DOI: 10.1093/alcalc/agae057] [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: 03/10/2024] [Revised: 08/01/2024] [Accepted: 08/05/2024] [Indexed: 10/08/2024] Open
Abstract
BACKGROUND Vaccine hesitancy is increasingly recognized as a health challenge affecting populations worldwide. Given the biological vulnerabilities and structural barriers people who use substances and/or have behavioral addictions face, this systematic review aims to evaluate whether this subpopulation is less prone to adhere to vaccination recommendations. METHODS Electronic searches of published original research were conducted in PubMed, EMBASE, Scopus, and PsycINFO from database inception to December 2022. Our strategy encompassed retrievals regardless of languages and date of publication. Animal studies, abstracts without a full manuscript, and studies which were considered to have lower robustness of scientific evidence were excluded. Outcomes measured were vaccine acceptance, uptake, and adherence. Results were interpreted through a narrative synthesis. RESULTS The search yielded 103 retrievals encompassing data collected on 5 576 374 persons who were predominantly residents of Europe (n = 39) and North America (n = 27). Tobacco use, the substance for which many studies were found (n = 91), was significantly associated with poorer vaccine acceptance, uptake and adherence for influenza, COVID-19, human papillomavirus (HPV), and maternal and childhood vaccines. Peri-natal and parental substance use was identified as a risk factor for suboptimal vaccine-related outcomes concerning maternal COVID-19 and childhood vaccines. Finally, people identified as 'using', 'abusing', or 'misusing' drugs or substances may be at decreased odds of all outcomes in various vaccines. CONCLUSIONS Collectively, the studies identified several groups with statistically significant greater vaccine hesitancy and decreased engagement among whom targeted measures could be beneficial. Timely evidence, especially on behavioral addictions and substances besides tobacco, is lacking, and warrants urgent attention.

Abstract
People with HIV (PWH) are at increased risk of COVID-19 infection. Both Canadian (NACI) and US (CDC) guidelines recommend that all PWH receive at least 2 doses of COVID-19 vaccine, and a booster. We examined vaccination uptake among PWH in Southern Alberta, Canada. Among adult PWH, we evaluated COVID-19 vaccination uptake between December 2020 and August 2022. Poisson regression models with robust variance (approximating log binomial models) estimated crude and adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for receiving (1) any vs. no vaccine, and (2) primary series with booster (≥ 3 vaccines) versus primary series without booster. Among 1885 PWH, 10% received no COVID-19 vaccinations, 37% < 3 vaccines and 54% received ≥ 3 vaccines. Females (vs. males) were less likely to receive a vaccine booster. Receiving no COVID-19 vaccines was associated with White ethnicity, unsuppressed HIV viral load (> 200 copies/mL), and using illegal substances. Factors associated with decreased booster uptake included being younger, Black (vs. White) ethnicity, substance use, lower educational attainment, and having an unsuppressed HIV viral load. COVID-19 booster uptake among PWH does not meet vaccine guidelines, and receipt of vaccines is unevenly distributed. Booster uptake is lowest among young females and marginalized individuals. Focused outreach is necessary to close this gap.

Abstract
To reduce morbidity and mortality associated with vaccine-preventable diseases (VPD), it is imperative that vaccination programs are implemented and prioritized throughout all stages of life across all populations. This study aimed to determine vaccine uptake and barriers to vaccination against VPDs among at-risk adult populations in the United States. We conducted a systematic literature review for articles published between January 2010 and June 2020 and identified 153 publications. The review identified 17 at-risk populations. Vaccine uptake was suboptimal among many populations, with factors including age, gender, and disease severity, associated with uptake. This review identified several barriers that impact vaccine uptake among at-risk populations, with concerns over safety, vaccine costs, lack of insurance, and lack of provider recommendation commonly reported across populations. Embracing a national life-course immunization framework that integrates developing policies, guidelines, and education would be a step to addressing these barriers.

Abstract
Background Despite the burden of disease and increased risk of influenza-associated morbidity and mortality among PLWHA, influenza vaccination has been understudied in this population. Methods We built an 11-year cohort of HIV-infected adults from medical records of PLWHA seeking care within the Louisiana State University medical system from June 2002-June 2013. Influenza vaccination uptake among PLWHA was calculated overall and for each medical facility for each influenza season. Linear regression was used to assess influenza vaccination uptake over time, both overall and by facility. Data were restricted to the final influenza season (2012-13) to assess predictors of PLWHA vaccination. Individuals were nested within medical facilities in order to assess the amount of variability in influenza vaccination rates across medical facilities. Results Influenza vaccination uptake among PLWHA increased over the study period (p < 0.01). The overall proportion of PLWHA vaccinated during the 2012-13 influenza season was 33.7%. 37.9% of the variability in the model occurred at the facility-level. Conclusions Although there was an increase in influenza vaccination within the PLWHA cohort over the course of the study, vaccination rates remained low overall. Special efforts must be made to increase vaccination uptake among PLWHA, with particular focus on those within the population who are likely to be at highest risk. The substantial variability at the facility-level indicates that there are unmeasured facility-level factors that contribute significantly to PLWHA vaccination.

Sociodemographic, HIV-Related Characteristics, and Health Care Factors as Predictors of Self-Reported Vaccination Coverage in a Nationwide Sample of People Aging with HIV in Germany. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18094901.

Abstract
Preventing infectious diseases through vaccination becomes more significant among the growing population of people aging with HIV. Coverage rates for vaccinations and factors associated with vaccination utilization among this population in Germany are unknown. We assessed the coverage of eight recommended vaccinations in a certain time frame in our convenience sample of 903 people living with HIV aged 50 years and older. We analysed coverage rates and used bivariate and multiple linear regression analyses to identify factors associated with number of reported vaccinations. Coverage rates in our sample ranged between 51.0% for meningococcus disease and 84.6% for the triple vaccination against tetanus, diphtheria, and pertussis. All rates were higher compared to the German general population. Seven factors were related to the number of vaccinations in multiple regression analysis: sexual orientation, education, relationship status, CD4 count, time since last visit to HIV specialist, type of HIV specialist, and distance to HIV specialist. Vaccination coverage among people aging with HIV in Germany is high, but not optimal. To improve vaccination uptake, strengthened efforts need to be focused on female and heterosexual male patients, socioeconomically disadvantaged patients, and patients with barriers to access regular HIV care.

Abstract
Annual influenza vaccination is recommended for all people living with HIV (PLWH), and so is pneumococcal vaccination at least once. This is due to higher incidence rates for both infections among PLWH, compared to HIV negative, even in the later highly active antiretroviral therapy era. To clarify the uptake of and attitude toward both vaccines among PLWH in Denmark, a survey on self-reported vaccine uptake was performed during 2017. Analyses identifying factors associated with vaccine uptake in the latest season for 203 participants were performed. Both influenza and pneumococcal vaccination uptake are low among PLWH in Denmark, 31.0% and 4.4%, respectively. Previous vaccination against influenza had the highest impact on influenza vaccine uptake, and lack of immunization guidance lowers the likelihood. Interventions to improve vaccination coverage are needed, such as increased awareness about guidelines and physician education.

Determinants of Vaccination Uptake in Risk Populations: A Comprehensive Literature Review. Vaccines (Basel) 2020; 8:vaccines8030480.

Abstract
Vaccination uptake has decreased globally in recent years, with a subsequent rise of vaccine-preventable diseases. Travellers, immunocompromised patients (ICP), and healthcare workers (HCW) are groups at increased risk for (severe) infectious diseases due to their behaviour, health, or occupation, respectively. While targeted vaccination guidelines are available, vaccination uptake seems low. In this review, we give a comprehensive overview of determinants-based on the integrated change model-predicting vaccination uptake in these groups. In travellers, low perceived risk of infection and low awareness of vaccination recommendations contributed to low uptake. Additionally, ICP were often unaware of the recommended vaccinations. A physician's recommendation is strongly correlated with higher uptake. Furthermore, ICP appeared to be mainly concerned about the risks of vaccination and fear of deterioration of their underlying disease. For HCW, perceived risk of (the severity of) infection for themselves and for their patients together with perceived benefits of vaccination contribute most to their vaccination behaviour. As the determinants that affect uptake are numerous and diverse, we argue that future studies and interventions should be based on multifactorial health behaviour models, especially for travellers and ICP as only a limited number of such studies is available yet.

Abstract
: HIV in the antiretroviral therapy era is characterized by multimorbidity and the frequent occurrence of HIV-associated non-AIDS chronic health conditions. Respiratory symptoms and chronic pulmonary diseases, including chronic obstructive pulmonary disease, asthma, and cardiopulmonary dysfunction, are among the conditions that may present in persons living with HIV. Tobacco smoking, which is disproportionately high among persons living HIV, strongly contributes to the risk of pulmonary disease. Additionally, features associated with and at times unique to HIV, including persistent inflammation, immune cell activation, oxidative stress, and dysbiosis, may also contribute. This review summarizes the available literature regarding epidemiology of and risk factors for respiratory symptoms and chronic pulmonary disease in the current era.

Abstract
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.

Abstract
OBJECTIVES Influenza vaccination is recommended for HIV-infected patients, but limited data about vaccination rates are available. The aim of this study was to evaluate the coverage of and predictors for influenza vaccination among HIV-positive patients. METHODS All HIV-positive patients who visited the HIV out-patient department of the University Hospital of Vienna, Austria, between June and August 2015 were asked to participate in this survey by completing a questionnaire. RESULTS A total of 455 HIV-positive patients completed a questionnaire, with 359 male and 96 female participants with a mean age of 46 years. The influenza vaccination rate for the previous season (2014/2015) was 11.9% [n = 54/455; 95% confidence interval (CI) 9.2-15.2%]. Older age was significantly associated with a positive influenza vaccination status. Obtaining information through a medical consultation or receiving a direct recommendation for vaccination by a physician had a significant impact on vaccination behaviour. The probability of being vaccinated against influenza was about 13 times higher among patients who received a recommendation for vaccination by their family physician or by their HIV specialist (P < 0.001). Important reasons for declining vaccination were fear of side effects (39%), not considering influenza as a severe disease (36%) and reasons related to HIV: 17% were worried that the vaccine could worsen the course of HIV infection and 16% believed vaccination would fail because of their compromised immune system. CONCLUSIONS A low influenza vaccination rate of 11.9% was detected in this HIV-positive cohort. The most effective impact for a positive vaccination status was direct recommendation of the influenza vaccine by the attending physician.

Abstract
INTRODUCTION During the 2009-2010 H1N1 pandemic, children and high-risk adults had priority for vaccination. Vaccine in short supply was allocated to states pro-rata by population, but vaccination rates as of January 2010 varied among states from 21.3% to 84.7% for children and 10.4% to 47.2% for high-risk adults. States had different campaign processes and decisions. OBJECTIVE To determine program and system factors associated with higher state pandemic vaccination coverage for children and high-risk adults during an emergency response with short supply of vaccine. METHODS Regression analysis of factors predicting state-specific H1N1 vaccination coverage in children and high-risk adults, including state campaign information, demographics, preventive or health-seeking behavior, preparedness funding, providers, state characteristics, and surveillance data. RESULTS Our modeling explained variation in state-specific vaccination coverage with an adjusted R-squared of 0.82 for children and 0.78 for high-risk adults. We found that coverage of children was positively associated with programs focusing on school clinics and with a larger proportion of doses administered in public sites; negatively with the proportion of children in the population, and the proportion not visiting a doctor because of cost. The coverage for high-risk adults was positively associated with shipments of vaccine to "general access" locations, including pharmacy and retail, with the percentage of women with a Pap smear within the past 3 years and with past seasonal influenza vaccination. It was negatively associated with the expansion of vaccination to the general public by December 4, 2009. For children and high-risk adults, coverage was positively associated with the maximum number of ship-to-sites and negatively associated with the proportion of medically underserved population. CONCLUSION Findings suggest that distribution and system decisions such as vaccination venues and providers targeted can positively impact vaccination rates for children and high-risk adults. Additionally, existing health infrastructure, health-seeking behaviors, and access affected coverage.

Abstract
This article reviews the evidence base on the social and psychological factors that facilitate or hinder vaccination among adults. The authors categorized these factors into eight themes: social influence, disease-related factors, vaccine-related factors, habit, general attitudes toward health and vaccines, awareness and knowledge, practical barriers and motivators and altruism. Although there were many commonalities between both settings, the authors also indentifiedimportant differences. A better understanding of social and psychological aspects of vaccination across contexts and vaccines remains a priority.

Abstract
AIM To measure the seasonal influenza vaccination coverage rate (VCR) in France in 2010, one year after the A(H1N1) influenza pandemic, and 2011 by age and target disease and to identify risk factors associated with a lack of vaccination in 2010 for those previously vaccinated in 2009. METHODS At the beginning of each vaccination campaign, the National Health Insurance, covering 86% of the French population, sends free influenza vaccination vouchers to at-risk beneficiaries aged under 65 suffering from diverse target diseases and to all individuals aged 65 and over (around 11.5 million). RESULTS The global VCR (50.4%), except people with asthma identified by drug refunds, decreased in 2010 compared with the previous three years when it was close to 60% (51.0% in 2011). For people under 65 years old, it fell from 40.3% in 2009 to 31.6% in 2010 (33.1% in 2011) and those aged 65 years and over from 63.3% to 53.8% (54.0% in 2011). The VCR of each target disease also decreased, especially for asthma, but not for HIV infection with campaign modification in 2010. It decreased among those aged 65 years and over with target disease (72.3% in 2009, 60.4% in 2010, 60.7% in 2011). Vaccination lack in 2010 was found to be associated with younger age, low number of drug deliveries and consultations with a general practitioner or a specialist, hospitalisation and the residence in a region of South of France or in overseas regions. CONCLUSION An important decline of the VCR was observed in France since 2010 while the recommended VCR is 75%. Efforts must be led to improve the confidence of the insurant, especially towards the most fragile groups.

Prev Med 2011; 53:89-94. [PMID: 21569791 DOI: 10.1016/j.ypmed.2011.04.015] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2010] [Revised: 04/25/2011] [Accepted: 04/26/2011] [Indexed: 11/30/2022]
Abstract
BACKGROUND We sought to describe rates of vaccination among HIV-infected adults in care and identify factors associated with vaccination. METHODS Using data abstracted from medical records of participants in the HIV Outpatient Study (HOPS) during 8 influenza seasons (1999-2008) and negative binomial models with generalized estimating equation methods, we examined factors associated with increased prevalence of annual influenza vaccination. RESULTS Among active patients, 25.8% to 43.3% were vaccinated for influenza each year (annual mean=35%, test for trend p=0.71). Vaccination rates peaked in October and November of each season and decreased sharply thereafter. In multivariable analysis, patients who were male (67.2%), non-Hispanic white (70%) or Hispanic (66%), had lower HIV viral loads (73.5%), were prescribed antiretroviral treatment (72.7%), or had a greater number of clinical encounters per year (86.7%) were more likely to receive influenza vaccination. DISCUSSION The decreased likelihood of vaccination among women and non-Hispanic black patients suggests the need for focused efforts to reduce disparities. Increasing patient and clinician education on the importance of universal vaccination, and ensuring that vaccination activities continue in HIV clinics during the later months of the influenza season may improve influenza vaccine coverage.

Tuppin P, Samson S, Weill A, Ricordeau P, Allemand H. Seasonal influenza vaccination coverage in France during two influenza seasons (2007 and 2008) and during a context of pandemic influenza A(H1N1) in 2009. Vaccine 2011; 29:4632-7. [PMID: 21550376 DOI: 10.1016/j.vaccine.2011.04.064] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2010] [Accepted: 04/17/2011] [Indexed: 10/18/2022]
Abstract
OBJECTIVES To measure the seasonal influenza vaccination coverage rate (VCR) in France in 2009, year of the A(H1N1) influenza pandemic, by age and target disease and compare it with the VCR for the 2007 and 2008 influenza seasons. METHOD At the beginning of each annual seasonal vaccination campaign, the National Health Insurance, covering 86% of the French population, sends free influenza vaccination vouchers to at-risk beneficiaries aged under 65 suffering from diverse chronic diseases and to all individuals aged 65 and over (around 11 million). Vaccination is estimated from refund claims registered in the National Health Insurance Information System. RESULTS The global VCR for the target population was 51% in 2007, 55.8% in 2008 and 56.9% in 2009. In 2009, the VCR for children under 10 years old was 24.3%, 28.1% in the 10-19 age range, 39.2% in the 20-64 age range and 63.3% for individuals aged 65 and over, of which 72.3% with a targeted chronic disease and 56.9% without. The inclusion of asthma as a target disease, lowered the global VCR for children under 10 years old (30.6% without asthma) but VCR increased proportionally with the number of annual refunds for drugs against asthma and chronic obstructive pulmonary disease. The 2009 vaccine uptake rates in target group children, adolescents, young adults and to a lesser extent the population aged 65 and over suffering from a chronic disease (particularly chronic respiratory disease), could have been positively impacted by the A(H1N1) influenza context. CONCLUSION The influenza VCR varies considerably according to age and target disease but globally remains inferior to the recommended 75% coverage rate. These results permit the detailed analysis of VCR distribution by disease and target group and highlights areas for reflection and action. Specific studies should be conducted in order to understand why the VCR is lower in certain target groups.
