Ferrara M, Langiano E, Esposito M, Lo Moro G, Lombardi R, Vuolanto P, De Vito E. Key factors in complex public health interventions to address vaccine hesitancy using a multidisciplinary approach: the VAX-TRUST project. HEALTH EDUCATION RESEARCH 2024:cyae027. [PMID: 39178122 DOI: 10.1093/her/cyae027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 06/20/2024] [Accepted: 07/27/2024] [Indexed: 08/25/2024]
Abstract
The VAX-TRUST project addresses vaccine hesitancy in seven European countries with a systematic and evidence-based approach. Interventions, targeting healthcare professionals, draw from behavioural and social theories. A checklist, inspired by the TIDieR (Template for Intervention Description and Replication), ensures a detailed description of actions, transparency and replicability. The intervention development process begins with collaborative meetings and systematic revisions, concluding with external evaluations for replicability in diverse public health contexts. This study aims to provide valuable insights for future complex interventions in public health, based on lessons learnt to reduce the risk of vaccine-preventable diseases. The analysis of educational interventions within the VAX-TRUST project has led to the definition of precise guidelines to ensure their replicability and adaptation to various contexts, attempting to establish a universally applicable approach. Active participant engagement and consideration of local social dynamics, beyond information transmission, have emerged as key factors to improve intervention effectiveness. Various educational tools and collaboration with academic institutions have contributed to strengthening credibility.

Vaccine 2024; 42:3768-3773. [PMID: 38714451 DOI: 10.1016/j.vaccine.2024.04.089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 04/25/2024] [Accepted: 04/29/2024] [Indexed: 05/09/2024]
Abstract
CONTEXT Vaccination coverage against human papillomavirus (HPV) in school-based programs in Quebec, Canada, is suboptimal despite more than a decade of introduction. Three interventions to improve HPV vaccine acceptability and coverage in school-based programs were developed, implemented as part of a multicomponent strategy and evaluated. METHOD Sixty-four (64) schools were recruited, of which 32 received the interventions (pilot schools), and 32 received usual vaccination activities (control schools). Two approaches were used to assess the impact of the interventions. Pre-post questionnaires were completed by parents in both pilot and control schools. Quantitative analyses of vaccination coverage using the Quebec immunization registry were conducted. RESULTS Participating parents (n = 989 in the pre-intervention survey and n = 772 in the post-intervention one) were generally aware of HPV and HPV vaccination. Most parents were confident about vaccination, had little or no hesitation and had decided to have their child vaccinated. Parents in the pilot schools were less concerned about vaccine safety than those in the control schools after the interventions. Parents in the pilot schools were also more likely to have decided to have their child vaccinated. A statistically significant difference of 7.4 % in HPV vaccine coverage between pilot and control schools was observed (82.9 % vs 75.5 %, p <0.0001). CONCLUSION Although school-based programs offer equitable access to vaccination and minimize access barriers, it remains crucial to identify effective interventions to improve vaccine uptake further and reach the WHO cervical cancer elimination goal. Our multicomponent strategy appears to have positively impacted HPV vaccine acceptability and coverage and could be adapted to other contexts where vaccination is delivered in school-based programs.

Development of Promising Interventions to Improve Human Papillomavirus Vaccination in a School-Based Program in Quebec, Canada: Results From a Formative Evaluation Using a Mixed Methods Design. JMIR Form Res 2024; 8:e57118. [PMID: 38976317 PMCID: PMC11263894 DOI: 10.2196/57118] [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: 02/07/2024] [Revised: 03/20/2024] [Accepted: 03/21/2024] [Indexed: 07/09/2024] Open
Abstract
BACKGROUND Despite the availability of school-based human papillomavirus (HPV) vaccination programs, disparities in vaccine coverage persist. Barriers to HPV vaccine acceptance and uptake include parental attitudes, knowledge, beliefs, and system-level barriers. A total of 3 interventions were developed to address these barriers: an in-person presentation by school nurses, an email reminder with a web-based information and decision aid tool, and a telephone reminder using motivational interviewing (MI) techniques. OBJECTIVE Here we report on the development and formative evaluation of interventions to improve HPV vaccine acceptance and uptake among grade 4 students' parents in Quebec, Canada. METHODS In the summer of 2019, we conducted a formative evaluation of the interventions to assess the interventions' relevance, content, and format and to identify any unmet needs. We conducted 3 focus group discussions with parents of grade 3 students and nurses. Interviews were recorded, transcribed, and analyzed for thematic content using NVivo software (Lumivero). Nurses received training on MI techniques and we evaluated the effect on nurses' knowledge and skills using a pre-post questionnaire. Descriptive quantitative analyses were carried out on data from questionnaires relating to the training. Comparisons were made using the proportions of the results. Finally, we developed a patient decision aid using an iterative, user-centered design process. The iterative refinement process involved feedback from parents, nurses, and experts to ensure the tool's relevance and effectiveness. The evaluation protocol and data collection tools were approved by the CHU (Centre Hospitalier Universitaire) de Québec Research Ethics Committee (MP-20-2019-4655, May 16, 2019). RESULTS The data collection was conducted from April 2019 to March 2021. Following feedback (n=28) from the 3 focus group discussions in June 2019, several changes were made to the in-person presentation intervention. Experts (n=27) and school nurses (n=29) recruited for the project appreciated the visual and simplified information on vaccination in it. The results of the MI training for school nurses conducted in August 2019 demonstrated an increase in the skills and knowledge of nurses (n=29). School nurses who took the web-based course (n=24) filled out a pretest and posttest questionnaire to evaluate their learning. The rating increased by 19% between the pretest and posttest questionnaires. Several changes were made between the first draft of the web-based decision-aid tool and the final version during the summer of 2019 after an expert consultation of experts (n=3), focus group participants (n=28), and parents in the iterative process (n=5). More information about HPV and vaccines was added, and users could click if more detail is desired. CONCLUSIONS We developed and pilot-tested 3 interventions using an iterative process. The interventions were perceived as potentially effective to increase parents' knowledge and positive attitudes toward HPV vaccination, and ultimately, vaccine acceptance. Future research will assess the effectiveness of these interventions on a larger scale.

Mil Med 2024:usae323. [PMID: 38935398 DOI: 10.1093/milmed/usae323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 06/07/2024] [Accepted: 06/17/2024] [Indexed: 06/28/2024] Open
Abstract
INTRODUCTION During the coronavirus disease of 2019 (COVID-19) pandemic, routine childhood immunization rates dropped dramatically across the world, and the Military Health System (MHS) was no exception. In the MHS, which is a large, universally covered, low-to-no-cost health system, the immunization rates with the measles, mumps, and rubella (MMR) vaccine remain below the rate necessary to prevent community transmission of measles. We aimed to improve childhood immunization rates in the MHS with an expansive quality improvement project. MATERIALS AND METHODS Measles, mumps, and rubella immunization rates served as proxy outcome measures for routine immunization rates tracked by the Center for Disease Control multi-immunization combination measures. The tracked measure was the percentage of 16- to 18-month olds and 6-year olds who had received MMR #1 and MMR #2, respectively. Various countermeasures were implemented throughout the study period, and standard quality improvement analyses informed the effect of countermeasures. RESULTS By January 2023, the percentage of 16- to 18-month olds and 6-year olds who had received MMR #1 and MMR #2 was 85% and 91%, respectively, with no positive shift in immunization rates despite various countermeasures introduced during the study period. For reference, the MMR immunization rates of commercial health maintenance organization and commercial preferred provider organization for 24-month-old populations were 92% and 90.3%, respectively. On chart review, the most common cause for under-immunization (55%) was vaccine abandonment. MMR #1 rates rose to 92% in 24-month olds. CONCLUSIONS Measles, mumps, and rubella immunization rates within the MHS remained below commercial health system rates and below public health standards required for herd immunity despite various countermeasures throughout the COVID-19 pandemic. Immunization rates increased with age, suggesting that children within the MHS eventually catch up despite potential barriers.

Abstract
The worldwide elimination of measles and rubella is feasible, but not without overcoming the substantial challenge of vaccine hesitancy. This challenge is complicated by the spread of misinformation and disinformation fueled by rapidly progressing technologies and evolving forms of online communication. The recent COVID-19 pandemic has only added further complexity to this challenge. However, considerable progress has been made in understanding the scope of the problem and the complex factors that influence vaccine hesitancy. Our understanding of evidence-based strategies for addressing vaccine hesitancy has grown significantly, including evidence for effective communication and behavioral interventions. In this article, we review measles and rubella vaccines and vaccine hesitancy. We then provide an overview of evidence-based strategies for addressing vaccine hesitancy, including communication strategies and behavioral interventions. This article is relevant to healthcare professionals, health system leaders, public health professionals, policymakers, community leaders, and any individuals who have a role in addressing vaccine hesitancy in their communities. Finally, we review future directions and major areas of research need.

Abstract
PURPOSE OF REVIEW Completion of all doses in multidose vaccine series provides optimal protection against preventable infectious diseases. In this review, we describe clinical and public health implications of multidose vaccine series noncompletion, including current challenges to ensuring children receive all recommended vaccinations. We then highlight actionable steps toward achieving early childhood immunization goals. RECENT FINDINGS Although coverage levels are high for most early childhood vaccinations, rates of completion are lower for vaccinations that require multiple doses. Recent research has shown that lower family socioeconomic status, a lack of health insurance coverage, having multiple children in the household, and moving across state lines are associated with children failing to complete multidose vaccine series. These findings provide contextual evidence to support that practical challenges to accessing immunization services are impediments to completion of multidose series. Strategies, including reminder/recall, use of centralized immunization information systems, and clinician prompts, have been shown to increase immunization rates. Re-investing in these effective interventions and modernizing the public health infrastructure can facilitate multidose vaccine series completion. SUMMARY Completion of multidose vaccine series is a challenge for immunization service delivery. Increased efforts are needed to address remaining barriers and improve vaccination coverage in the United States.

Abstract
INTRODUCTION Meningococcal vaccinations are recommended by Polish public health authorities but lack coverage under health insurance, prompting Local Government Units (LGUs) to implement local health policy programs. This study examines the effectiveness and impact of LGU-driven meningococcal vaccination initiatives in Poland between 2017 and 2021. MATERIAL AND METHODS A retrospective analysis utilized data from reports on local public health interventions submitted annually to the Ministry of Health in Poland. The study focused on the number of meningococcal vaccination programs, their scope, the vaccinated population, and associated program costs. Additionally, nationwide data on meningococcal disease incidence and vaccine uptake were analyzed. RESULTS Within LGUs programs, 48,617 individuals received meningococcal vaccinations, constituting approximately 10% of all vaccinations in Poland during the study period. Notably, cities with poviat rights spearheaded programs covering 54% of the total participants. The total cost incurred by these initiatives amounted to EUR 2,553,661. CONCLUSIONS While LGUs activities positively contributed to increased meningococcal vaccination rates, the overall engagement of local governments remains limited. The findings underscore the importance of expanding local government involvement in meningococcal vaccination programs to address public health needs effectively. Improved collaboration and increased funding may enhance the reach and impact of these initiatives.

Abstract
Importance Pregnancy represents a window of opportunity for vaccination due to established maternal and fetal benefits of vaccination. Little is known about receipt of routinely recommended vaccines in pregnancy, specifically tetanus, diphtheria, plus acellular pertussis (Tdap) and influenza, among pregnant people living with HIV (PLHIV). Objective To estimate prevalence of vaccination receipt among pregnant people with HIV (PLHIV) and identify demographic and clinical characteristics associated with vaccination. Design, Setting, and Participants This multicenter cohort study included women participating in Women's Health Study (WHS) of the Surveillance Monitoring for ART Toxicities (SMARTT) Study of the Pediatric HIV/AIDS Cohort Study. The network has been enrolling pregnant PLHIV at 22 US sites since 2007. Participants for this study enrolled between December 2017 and July 2019. Data analysis was conducted from October 2021 to March 2022. Exposure Data on vaccination in pregnancy were collected through medical record abstraction. Main Outcomes and Measures Vaccination receipt was defined as Tdap vaccination received at less than 36 weeks' gestation and influenza vaccination at any gestational age, based on current guidelines. Log-binomial and modified Poisson regression models with generalized estimating equations were fit to identify factors associated with successful receipt of (1) Tdap, (2) influenza, and (3) both vaccinations. Results A total of 310 pregnancies among 278 people participating in the WHS were included (mean [SD] age, 29.5 [6.1] years; 220 [71%] Black, 77 [25%] Hispanic, and 77 [25%] race and ethnicity other than Black; 64 [21%] with perinatally acquired HIV). Less than one-third of pregnancies were vaccinated as recommended (Tdap, 32.6% [95% CI, 27.4%-38.1%]; influenza, 31.6% [95% CI, 26.5%-37.1%]; both, 22.6% [95% CI, 18.0%-27.6%]). People living with perinatally acquired HIV, those who did not identify as Black, or those who were multiparous had adjusted risk ratios (aRRs) less than 1, while older PLHIV had aRRs greater than 1, but these differences did not reach statistical significance (perinatally acquired HIV: adjusted risk ratio [aRR], 0.46; 95% CI, 0.21-1.02; race other than Black: aRR, 0.53; 95% CI, 0.26-1.08; multiparous: aRR, 0.59; 95% CI, 0.35-1.00; age 24-29 years: aRR, 2.03; 95% CI, 0.92-4.48). Conclusions and Relevance In this diverse, multicenter cohort of pregnant PLHIV, receipt of recommended vaccinations was low. Identifying and addressing barriers to vaccination receipt is urgently needed for pregnant people with HIV.

Abstract
OBJECTIVE Spatial clustering of undervaccination leads to increased risk of vaccine-preventable diseases. We identified spatial clustering of undervaccination patterns among children aged <24 months in Montana. METHODS We used Montana's immunization information system data to analyze deidentified vaccination records of children aged <24 months born from January 2015 through November 2017. We measured 3 outcomes that were not mutually exclusive: not completing the combined 7-vaccine series by age 24 months, having an undervaccination pattern indicative of parental hesitancy, and having an undervaccination pattern indicative of structural barriers to timely vaccination. Using geomasked residential addresses, we conducted separate Bernoulli spatial scans with a randomization P < .01 to identify spatial clusters consisting of ≥100 children for each outcome and calculated the relative risk of having the undervaccination pattern inside versus outside the cluster. RESULTS Of 31 201 children aged <24 months included in our study, 11 712 (37.5%) had not completed the combined 7-vaccine series by age 24 months, and we identified 5 spatial clusters of this outcome across Montana. We identified 4 clusters of undervaccination patterns indicative of parental vaccine hesitancy, all in western Montana. The cluster with the largest relative risk (2.3) had a radius of 23.7 kilometers (n = 762 children, P < .001). We also identified 4 clusters of undervaccination patterns indicative of structural barriers, with 3 of the largest clusters in eastern Montana. CONCLUSION In Montana, different strategies to increase routine and timely childhood vaccination are needed in distinct areas of this large and predominantly rural state. Immunization information system data can pinpoint areas where interventions to increase vaccination uptake are needed.

Abstract
Vaccines have led to a significant decrease in rates of vaccine-preventable diseases and have made a significant impact on the health of children. However, some parents express concerns about vaccine safety and the necessity of vaccines. The concerns of parents range from hesitancy about some immunizations to refusal of all vaccines. This clinical report provides information about the scope and impact of the problem, the facts surrounding common vaccination concerns, and the latest evidence regarding effective communication techniques for the vaccine conversation. After reading this clinical report, readers can expect to: Understand concepts and underlying determinants of vaccine uptake and vaccine hesitancy.Understand the relationship between vaccine hesitancy and costs of preventable medical care.Recognize and address specific concerns (eg, vaccine safety) with caregivers when hesitancy is present.

[PMID: 38355444 PMCID: PMC10868109 DOI: 10.1186/s12889-024-17957-5] [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: 06/05/2023] [Accepted: 02/01/2024] [Indexed: 02/16/2024] Open
Abstract
BACKGROUND Vaccine homophily describes non-heterogeneous vaccine uptake within contact networks. This study was performed to determine observable patterns of vaccine homophily, as well as the impact of vaccine homophily on disease transmission within and between vaccination groups under conditions of high and low vaccine efficacy. METHODS Residents of British Columbia, Canada, aged ≥ 16 years, were recruited via online advertisements between February and March 2022, and provided information about vaccination status, perceived vaccination status of household and non-household contacts, compliance with COVID-19 prevention guidelines, and history of COVID-19. A deterministic mathematical model was used to assess transmission dynamics between vaccine status groups under conditions of high and low vaccine efficacy. RESULTS Vaccine homophily was observed among those with 0, 2, or 3 doses of the vaccine. Greater homophily was observed among those who had more doses of the vaccine (p < 0.0001). Those with fewer vaccine doses had larger contact networks (p < 0.0001), were more likely to report prior COVID-19 (p < 0.0001), and reported lower compliance with COVID-19 prevention guidelines (p < 0.0001). Mathematical modelling showed that vaccine homophily plays a considerable role in epidemic growth under conditions of high and low vaccine efficacy. Furthermore, vaccine homophily contributes to a high force of infection among unvaccinated individuals under conditions of high vaccine efficacy, as well as to an elevated force of infection from unvaccinated to suboptimally vaccinated individuals under conditions of low vaccine efficacy. INTERPRETATION The uneven uptake of COVID-19 vaccines and the nature of the contact network in the population play important roles in shaping COVID-19 transmission dynamics.

Knowledge, Attitudes and Practices Survey of Recombinant Zoster Vaccine among Cardiologists and Cardiac Nurses in Italy. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:93. [PMID: 38256354 PMCID: PMC10820166 DOI: 10.3390/medicina60010093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 12/20/2023] [Accepted: 01/02/2024] [Indexed: 01/24/2024]
Abstract
Background and Objectives: Cardiac patients are particularly at risk of herpes zoster (HZ), which is associated with a higher risk of major cardiovascular events. This research aimed to analyze the knowledge, attitudes and practices towards recombinant zoster vaccine (RZV) among cardiac healthcare professionals (HPs). Materials and Methods: A cross-sectional survey was conducted in a cardiological hospital in Italy. Multivariate regression models were built to identify factors associated with the outcomes of interest. Results: The response rate was 78.2% (154/197). Overall, age > 50 years and immunosuppression were recognized as risk factors for HZ by 38.3% and 75.3% of respondents, respectively. Regarding RZV, 29.1% of the HPs correctly responded about its schedule and 57.6% about the possibility of administration in immunocompromised individuals. This knowledge was significantly higher in HPs with a higher educational level (odds ratio (OR) = 4.42; 95%CI 1.70-11.47), in those who knew that HZ could cause postherpetic neuralgia (OR = 2.56; 95%CI 1.05-6.25) or major cardiovascular events (OR = 4.23; 95%CI 1.50-11.91), in those who had participated in professional updates on vaccinations (OR = 3.86; 95%CI 1.51-9.87) and in those who stated the need for further information about the RZV (OR = 6.43; 95%CI 1.42-29.98). Younger HPs (coefficient (β) = -0.02; 95%CI -0.04--0.01), those with a positive attitude toward RZV safety (β = 2.92; 95%CI 2.49-3.36) and those who had previously cared for patients with HZ (β = 0.45; 95%CI 0.03-0.88) reported a more positive attitude toward RZV effectiveness. The practice of recommending vaccination was more prevalent in younger HPs (OR = 0.94; 95%CI 0.89-0.99), in those who had a master's degree or higher education (OR = 7.21; 95%CI 1.44-36.08), in those with more positive attitudes toward RZV effectiveness (OR = 7.17; 95%CI 1.71-30.03) and in HPs who had already recommended the vaccine to patients in the past (OR = 4.03; 95%CI 1.08-14.96). Conclusions: Despite being a single-center study, our research brings attention to factors that currently impact cardiac HPs' approaches to RZV. The findings indicate potential measures to enhance HPs' awareness and practices, ultimately aiming to improve vaccination adherence and reduce the burden associated with HZ.

Abstract
The Herpes Zoster (HZ) vaccination has proven both safe and effective in alleviating conditions related to HZ, leading to significant cost savings in national healthcare and social systems. In Italy, it is recommended and provided free of charge to individuals aged 65 and older. To achieve broad vaccination coverage, alongside ordinary immunization campaigns, active and catch-up campaigns were implemented. This retrospective observational study aimed to observe the vaccination coverage achieved in the Romagna Local Health Authority (LHA) during the 2023 active campaign, with a secondary goal of assessing the impact of the 2022 catch-up campaign and the 2023 active campaign compared to ordinary campaigns. As of 3 July 2023, an overall vaccine uptake of 13.5% was achieved among individuals born in 1958, with variations among the four LHA centers ranging from 10.2% to 17.7%. Catch-up and active campaigns together contributed to nearly half of the achieved coverage in Center No. 1 and a quarter in Center No. 2. Notably, individuals born in 1957, not included in the Center No. 2 catch-up campaign, reached significantly lower vaccination coverage compared to other cohorts and centers. Analyzing the use of text messages for active campaigns, it was observed that cohort groups did not show substantial differences in text-message utilization for warnings. However, having relatives who had experienced HZ-related symptoms significantly reduced the reliance on text messages as warnings. These results highlighted how catch-up and active campaigns effectively increased vaccine coverage. Nevertheless, differences in uptake among different centers within the same LHA and the limited contribution of other information sources compared to text messages suggest the necessity of designing campaigns involving all available channels and stakeholders to maximize vaccine uptake.

Abstract
In 2019, ACWY meningococcal vaccination for people born between 2001 and 2007 was recommended. In Murcia, during the first 9 months, the coverage was 52.89%. This study is aimed to evaluate the effects of e-mail reminders on vaccination coverage. A longitudinal, prospective trial was performed on non-vaccinated individuals with e-mail addresses. An e-mail reminder was sent to people assigned to the intervention group (born in any month, except January and July), and 4 weeks later, the same was sent to the control group. Vaccination coverage was assessed before and 4 weeks after each intervention. After the first intervention, 5.15% of the participants in the intervention group were vaccinated (1.57% in the control group). The increased likelihood of being vaccinated if a person had been sent an e-mail was 1.033 (95% confidence interval, 1.019-1.047; p = 0.001). This study highlighted the impact of e-mail as an appropriate method of communication for vaccination programmes.

Hum Vaccin Immunother 2023; 19:2274723. [PMID: 37929936 PMCID: PMC10629428 DOI: 10.1080/21645515.2023.2274723] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 10/20/2023] [Indexed: 11/07/2023] Open
Abstract
Human papillomavirus (HPV) vaccination rates are lower than Tetanus-diphtheria-pertussis (Tdap) and Meningococcal conjugate (MenACWY) rates, although the Advisory Committee on Immunization Practices recommends all three vaccines be given routinely at age 11-12. Evidence is mounting that children who initiate HPV vaccination starting at age 9 are more likely to complete the series on time. Washington state implemented a provider reminder through its immunization information system (WAIIS) in January 2023 to increase HPV vaccine initiation at 9-years-old by updating the forecasted recommended age for HPV from age 11 to 9. The effectiveness of provider reminders when implemented via an immunization information system (IIS) is poorly understood. We evaluated the impact of this forecast update using a seasonally adjusted interrupted time series regression of weekly HPV initiations at 9-years-old before and after implementation. We also examined time series trends of vaccine administration between 2018 and 2023 for HPV initiation at age 9, as well as Tdap, MenACWY and HPV initiation at age 11. The WAIIS forecast update doubled the weekly rate of HPV initiation among 9-year-olds in Washington state, although the weekly count of initiation at 9 remains far lower than initiations at 11. Jurisdictions wanting to increase HPV vaccine initiation at earlier ages should consider updating their forecast algorithm and investing in complementary evidence-based strategies such as provider and parent education, and clinic-based quality improvement efforts. The reach of IIS forecaster updates may be enhanced by working with administrators of electronic medical record systems to ensure parity of provider prompts with IIS.

Abstract
Introduction Primary care providers' (PCPs) compliance to self-immunization is important for their protection and the protection of their colleagues and patients and has been associated with the coverage of the general public. In this study, we aim to investigate the vaccination coverage of PCPs. Methods A questionnaire-based cross-sectional survey was conducted among physicians, nurses and pharmacists employed in public or private primary care settings in Greece. Demographic and occupational characteristics as well as vaccination coverage data for influenza, tetanus, pneumococcal pneumonia and herpes zoster were collected. Statistical significance was set at 0.05. Results In total, 748 (61.7% response rate) PCPs participated. Vaccination rates were 66.4% (496/747) for influenza (2019/2020 flu season), 62.9% (469/746) for tetanus (10-year Td or Tdap booster dose), 70% (14/20) for pneumococcal pneumonia (≥ 1 dose of PPSV23 or PCV13) and 12.3% (10/81) for herpes zoster. Multiple logistic regression revealed that nurses had significantly lower probability of being vaccinated against influenza [odds ratio (OR) = 0.25; 95% confidence interval (CI) = 0.14-0.45] and pharmacists had significantly lower probability of being vaccinated against both influenza (OR = 0.44; 95% CI = 0.31-0.62) and influenza & tetanus (OR = 0.52; 95% CI = 0.37-0.73) compared to physicians. Older age (>40 years) was an independent risk factor for not receiving a tetanus vaccine (40-49 vs. 19-39; OR = 0.42; 95% CI = 0.28-0.63, over 50 years old vs. 19-39; OR = 0.54; 95% CI = 0.36-0.79). Conclusions The results revealed suboptimal vaccination rates among health providers who are in the frontline of adult immunization. Individualized and targeted measures to improve their vaccination coverage and indirectly the vaccination coverage of their patients, are therefore required.

Haeder SF. U.S. public support and opposition to vaccination mandates in K-12 education in light of the COVID-19 pandemic. Vaccine 2023; 41:7103-7115. [PMID: 37858447 DOI: 10.1016/j.vaccine.2023.10.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 10/06/2023] [Accepted: 10/07/2023] [Indexed: 10/21/2023]
Abstract
BACKGROUND Vaccination mandates have long been an effective tool in increasing vaccination rates and reducing the potential for disease outbreaks. In the wake of COVID-19, opposition to mandates in the K-12 setting has garnered more attention, and policymakers opposed to them have become more active. This study sought to assess whether these efforts are supported by the U.S. public. METHODS We fielded a large, national survey (N = 16,461) from January to April of 2022 to assess U.S. public opinion about seven specific vaccination mandates (diphtheria, tetanus, & pertussis (DTaP); polio; chickenpox; measles, mumps, and rubella (MMR); hepatitis; human papillomavirus (HPV); and COVID-19) in K-12 educational settings. RESULTS We found that Americans are overwhelmingly supportive of all vaccination mandates with support ranging from a high 90 percent of respondents for DTaP, polio, chickenpox, and MMR to a low of 68 percent for COVID-19. Individuals who deemed vaccines safe and important, those with trust in the National Institutes of Health and the Food and Drug Administration, urban residents, and ethnic and racial minorities tended to be consistently more supportive. Perceptions about vaccine effectiveness were positively associated with mandate support in most cases, as was trust in medical doctors. Respondents who believed that vaccines cause autism, those with better health and more trust in religious leaders tended to be consistently more opposed. Women were generally more supportive of mandates except for HPV and COVID-19. Ideology and partisanship affected opinion for COVID-19 as did trust in the Centers for Disease Control and Prevention. We found no effects for income or education. CONCLUSION Vaccination mandates in K-12 have broad support among the American public, even in more controversial cases such as HPV and COVID-19. Vocal opposition and growing interest by policymakers to limit or undo vaccination mandates are not supported by the broader public.

Abstract
National Immunization Survey-Child data collected in 2022 were combined with data from previous years to assemble birth cohorts and assess coverage with routine vaccines by age 24 months by birth cohort. Overall, vaccination coverage was similar among children born during 2019-2020 compared with children born during 2017-2018, except that coverage with both the birth dose of hepatitis B vaccine and ≥1 dose of hepatitis A vaccine increased. Coverage was generally higher among non-Hispanic White (White) children (2-21 percentage points higher than coverage for non-Hispanic Black or African American, Hispanic or Latino, and non-Hispanic American Indian/Alaska Native [AI/AN] children), children living at or above poverty (3.5-22 percentage points higher than coverage for children living below the federal poverty level), privately insured children (2.4-38 percentage points higher than coverage for children with Medicaid, other insurance, or no insurance), and children in urban areas (3-16.5 percentage points higher than coverage for children living in rural areas). Coverage with the full series of Haemophilus influenzae type b conjugate vaccine was lower among AI/AN children compared with White children. Trends in vaccination coverage disparities across categories of race and ethnicity, health insurance status, poverty status, and urbanicity were evaluated for the 2016-2020 birth cohorts. Fewer than 5% of 168 trends examined were statistically significant, including six increases (widening of the coverage gap) and one decrease (narrowing of the gap). Analyses revealed a widening of the gap between children living at or above the poverty level (higher coverage) and those living below poverty (lower coverage), for several vaccines. Socioeconomic, demographic, and geographic disparities in vaccination coverage persist; addressing them is important to ensure protection for all children against vaccine-preventable disease.

Abstract
BACKGROUND Vaccine hesitancy is relevant for healthcare professionals (HCPs) who face challenges in building trusting relationships with patients. Accordingly, the VAX-TRUST project has been developed to improve experiences of HCPs and patients dealing with vaccinations. To support VAX-TRUST, this work aimed to identify latest interventions targeted at HCPs to address hesitancy and increase vaccine uptake. METHODS A systematic review was conducted according to PRISMA by searching PubMed, Scopus and Embase. The protocol was registered on PROSPERO. Articles were eligible if evaluated interventions directly targeted at HCPs/healthcare students. The search was run on 26 January 2022. Articles published in 2016 or after were included. RESULTS A total of 17 492 records were identified; 139 articles were selected. Most articles were set in USA (n = 110). Over half had a pre-post design without a control group (n = 78). A total of 41 articles focused on single-component interventions, 60 on multi-component interventions involving only HCPs and/or students and 38 on multi-component interventions involving also other professionals. Main components were in-person education (n = 76), synchronous (n = 10) and asynchronous (n = 23) online learning, educational materials (n = 26), performance assessment and feedback (n = 33), electronic record changes (n = 30), role play/simulation (n = 21) and online games/apps (n = 5). Educational sessions were mainly about scientific update or communication. Outcomes of interventions were grouped in: vaccination rates (n = 69), knowledge (n = 32), attitudes (n = 26), confidence in counselling (n = 30) and acceptability (n = 16). CONCLUSIONS Apps, gaming, role play/simulations could represent innovative interventions. This review highlighted the need of delving into communication strategies and using more robust evaluations, longer follow-up and standardized measurements.

Abstract
The purpose of our study was to identify primary care providers' (PCPs') practices in promoting childhood vaccination and their perceptions regarding barriers to vaccination in a primarily rural state. In January-May 2022, we conducted a mail and online survey of PCPs across Montana (n = 829). The survey included modules on routine immunizations in children 0-2 years old and COVID-19 vaccination in children 5-17 years old. The survey response rate was 36% (298/829). We categorized PCPs as working in rural (n = 218) or urban areas (n = 80), based on Rural-Urban Commuting Area codes. We then compared responses between rural and urban PCPs using chi-square tests. Urban PCPs (90-94%, depending on vaccine) stocked routinely recommended vaccines more frequently than rural PCPs (71-84%), but stocked the COVID-19 vaccine less often than rural PCPs (44% vs. 71%, respectively, p < 0.001). A higher percentage of rural providers reported parental beliefs that vaccine-preventable diseases are not severe enough to warrant vaccination (48% vs. 31%, p = 0.01) and concerns that vaccination will weaken their child's immune system (29% vs. 6%, p < 0.001). More rural (74%) compared to urban (59%) PCPs identified a social media campaign from local health departments promoting early childhood vaccinations as an effective strategy to increase childhood vaccination rates (p = 0.01). We identified key differences in some childhood vaccination practices and barriers between rural and urban PCPs. Interventions to increase rural vaccination rates could include increasing the number of providers stocking all recommended vaccines, identifying strategies to address parents' concerns regarding vaccine necessity, and collaborations with public health departments.

Abstract
This technical report accompanies the recommendations of the American Academy of Pediatrics for the routine use of influenza vaccine and antiviral medications in the prevention and treatment of influenza in children during the 2023-2024 season. The rationale for the American Academy of Pediatrics recommendation for annual influenza vaccination of all children without medical contraindications starting at 6 months of age is provided. Influenza vaccination is an important strategy for protecting children and the broader community against influenza. This technical report summarizes recent influenza seasons, morbidity and mortality in children, vaccine effectiveness, and vaccination coverage, and provides detailed guidance on vaccine storage, administration, and implementation. The report also provides a brief background on inactivated and live-attenuated influenza vaccines, available vaccines this season, vaccination during pregnancy and breastfeeding, diagnostic testing for influenza, and antiviral medications for treatment and chemoprophylaxis. Strategies to promote vaccine uptake are emphasized.

A cross-sectional study among French adults. Vaccine 2023; 41:5412-5423. [PMID: 37481404 DOI: 10.1016/j.vaccine.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 05/22/2023] [Accepted: 07/02/2023] [Indexed: 07/24/2023]
Abstract
BACKGROUND In August 2021, France enacted a COVID-19 certificate requirement (vaccination/recovery/test) to access specific services, with mandates for professional groups. We evaluated the impact of this incentive-coercive policy in terms of vaccine uptake equality, future vaccine intention and confidence in authorities' crisis management. METHODS In late August 2021, a representative sample of adults (18-75 years) completed an internet-based questionnaire. We classified vaccinated participants by stated reasons for vaccination and estimated adjusted prevalence ratios (aPR) using multivariable Poisson regression. Counterfactual vaccine status assumed non-vaccination of those vaccinated for the certificate. We analysed the association of free-text testimonial themes with level of confidence in authorities. RESULTS Among 972 participants, 85.7% were vaccinated or intended vaccination: 3.6% only for certificate/mandate, 17.7% mainly for certificate/mandate plus other reasons, and 64.4% mainly for other reasons. In the counterfactual situation, vaccine uptake would have been significantly more likely among older vs. younger participants (aPR = 1.35) and among those with moderate-high vs. low levels of confidence in authorities for COVID-19 crisis management (aPR = 2.04). In the observed situation, confidence was the only significant determinant of vaccine status (moderate-high vs. low, aPR = 1.39). Among those without genuine motivation for vaccination, professionally active persons were more likely to have ceded to the certificate requirement (aPR = 3.76). Those vaccinated only for the certificate were more likely to express future COVID-19 vaccine intention than unvaccinated persons (aPR = 6.41). Themes significantly associated with lower confidence were criticism of morality (aPR = 1.76) and poor communication by the authorities (aPR = 1.66). CONCLUSION The incentive-coercive policy has reduced the negative association of vaccine status with younger age and low confidence in authorities, but may have reinforced isolation of professionally inactive persons. The requirement did not negatively impact future COVID-19 vaccine intention. Future vaccine-incentive policies should pay special attention to populations with low levels of confidence in authorities.

Abstract
The purpose of this article is to provide an overview of effective strategies for working with parents' vaccination hesitancy or refusal. An overview of historical and current trends in vaccination hesitancy and factors that contribute to and strategies for addressing vaccine hesitancy are discussed. This includes an emphasis on the critical role played by health care providers, as trusted advisors and a primary source of health care information, in encouraging vaccine acceptance. Legal and ethical implications are also considered. Vaccination hesitancy strategies are most effective if they are timely, multifaceted, and collaborative.

Abstract
BACKGROUND Most early childhood immunizations require 3 to 4 doses to achieve optimal protection. Our objective was to identify factors associated with starting but not completing multidose vaccine series. METHODS Using 2019 National Immunization Survey-Child data, US children ages 19 to 35 months were classified in 1 of 3 vaccination patterns: (1) completed the combined 7-vaccine series, (2) did not initiate ≥1 of the 7 vaccine series, or (3) initiated all series, but did not complete ≥1 multidose series. Associations between sociodemographic factors and vaccination pattern were evaluated using multivariable log-linked binomial regression. Analyses accounted for the survey's stratified design and complex weighting. RESULTS Among 16 365 children, 72.9% completed the combined 7-vaccine series, 9.9% did not initiate ≥1 series, and 17.2% initiated, but did not complete ≥1 multidose series. Approximately 8.4% of children needed only 1 additional vaccine dose from 1 of the 5 multidose series to complete the combined 7-vaccine series. The strongest associations with starting but not completing multidose vaccine series were moving across state lines (adjusted prevalence ratio [aPR] = 1.45, 95% confidence interval [CI]: 1.18-1.79), number of children in the household (2 to 3: aPR = 1.29, 95% CI: 1.05-1.58; 4 or more: aPR = 1.68, 95% CI: 1.30-2.18), and lack of insurance coverage (aPR = 2.03, 95% CI: 1.42-2.91). CONCLUSIONS More than 1 in 6 US children initiated but did not complete all doses in multidose vaccine series, suggesting children experienced structural barriers to vaccination. Increased focus on strategies to encourage multidose series completion is needed to optimize protection from preventable diseases and achieve vaccination coverage goals.

Abstract
Objective: This exploratory study examined campus attitudes toward vaccines to guide subsequent development of context-relevant interventions for increasing vaccine acceptance and uptake. Participants: We gathered ethnographic data on a convenience sample of campus community members (students, faculty, staff) at a public university over six weeks in spring 2022. Methods: Student researchers conducted a rapid ethnographic assessment across campus locations. Weekly team debriefs enabled ongoing, iterative refinement of instruments and supplemented observational fieldnotes. Data analysis was inductive and oriented toward practical recommendations for intervention development. Results: Four themes, and attendant recommendations, emerged: 1) social identities and social roles influence health-related beliefs, including vaccination; 2) vaccine knowledge influences vaccination behaviors; 3) language surrounding vaccines (sometimes) matters; 4) vaccines aren't considered part of general health and wellness and can't be forced. Conclusions: Findings highlight the need to address individual, social, and institutional contexts when designing campus-based behavioral interventions for vaccine uptake.

A Behavioural-Theory-Based Qualitative Study of the Beliefs and Perceptions of Marginalised Populations towards Community Volunteering to Increase Measles Immunisation Coverage in Sabah, Malaysia. Vaccines (Basel) 2023; 11:1056. [PMID: 37376445 DOI: 10.3390/vaccines11061056] [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: 03/24/2023] [Revised: 05/16/2023] [Accepted: 05/31/2023] [Indexed: 06/29/2023] Open
Abstract
The development of the measles-containing vaccine (MCV) has rendered measles a largely preventable disease. In the state of Sabah in Malaysia, a complete course of measles immunisation for infants involves vaccinations at the ages of six, nine, and twelve months. However, it is difficult for marginalised populations to receive a complete course of measles immunisation. This present study used behavioural theory (BT) to examine the beliefs and perceptions of a marginalised population towards community volunteering as a method of increasing the immunisation coverage of measles. Marginalised populations living in Kota Kinabalu, Sabah, more specifically, Malaysian citizens living in urban slums and squatter areas, as well as legal and illegal migrants, were extensively interviewed in person for this qualitative study. The 40 respondents were either the parents or primary caregivers of at least one child under the age of five. The components of the Health Belief Model were then used to examine the collected data. The respondents had poor awareness of the measles disease and perceived the disease as not severe, with some even refusing immunisation. The perceived barriers to receiving vaccinations included a nomadic lifestyle; issues with finances, citizenship status, language, and weather; failing to remember immunisation schedules; a fear of health care personnel; having too many children; and a lack of female autonomy in vaccine decision-making. However, the respondents were receptive towards community-based programmes and many welcomed a recall or reminder system, especially when the volunteers were family members or neighbours who spoke the same language and knew their village well. A few, however, found it awkward to have volunteers assisting them. Evidence-based decision making may increase measles immunisation coverage in marginalised populations. The components of the Health Belief Model validated that the respondents lacked awareness of the measles disease and viewed it and its effects as not severe. Therefore, future volunteer programmes should prioritise increasing the receptivity and self-control of marginalised populations to overcome barriers that hinder community involvement. A community-based volunteer programme is highly recommended to increase measles immunisation coverage.

Abstract
During the ongoing multi-country monkeypox (Mpox) outbreak, healthcare workers (HCWs) have represented a key group in mitigating disease spread. The current study aimed to evaluate the attitude of nurses and physicians in Jordan towards Mpox vaccination, as well as their attitude towards compulsory vaccination against coronavirus disease 2019 (COVID-19), influenza, and Mpox. An online survey was distributed in January 2023 based on the previously validated 5C scale for psychological determinants of vaccination. Previous vaccination behavior was assessed by inquiring about the history of getting the primary and booster COVID-19 vaccination, influenza vaccine uptake during COVID-19, and any history of influenza vaccine uptake. The study sample consisted of 495 respondents: nurses (n = 302, 61.0%) and physicians (n = 193, 39.0%). Four hundred and thirty respondents (86.9%) had heard of Mpox before the study, and formed the final sample considered for Mpox knowledge analysis. Deficiencies in Mpox knowledge were reflected in a mean knowledge score of 13.3 ± 2.7 (out of 20.0 as the maximum score), with significantly lower knowledge among nurses and females. The intention to receive Mpox vaccination was reported by 28.9% of the participants (n = 143), while 33.3% were hesitant (n = 165), and 37.8% were resistant (n = 187). In multivariate analysis, Mpox vaccine acceptance was significantly associated with previous vaccination behavior, reflected in higher vaccine uptake and with higher 5C scores, while Mpox knowledge was not correlated with Mpox vaccination intention. The overall attitude towards compulsory vaccination was neutral, while a favorable attitude towards compulsory vaccination was associated with higher 5C scores and a history of previous vaccination uptake. The current study showed a low intention to get Mpox vaccination in a sample of nurses and physicians practicing in Jordan. The psychological factors and previous vaccination behavior appeared as the most significant determinants of Mpox vaccine acceptance and of attitudes towards compulsory vaccination. The consideration of these factors is central to policies and strategies aiming to promote vaccination among health professionals in efforts to prepare for future infectious disease epidemics.

Microorganisms 2023; 11:microorganisms11040961. [PMID: 37110384 PMCID: PMC10146000 DOI: 10.3390/microorganisms11040961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 04/04/2023] [Accepted: 04/05/2023] [Indexed: 04/29/2023] Open
Abstract
In 2020, a record number of tick-borne encephalitis (TBE) cases was reported in major endemic areas in Germany, i.e., the southern federal states of Baden-Wuerttemberg and Bavaria. Most cases were unvaccinated. Other tick-borne diseases (TBDs), including Lyme borreliosis and tularemia, are rising, too. Thus, strategies are needed to increase TBE vaccination uptake in risk areas and promote education on TBD prevention. Primary care physicians are key providers of both vaccinations and TBD education. The TBD-Prevention (TBD-Prev) study aimed to investigate the knowledge, attitudes and behaviors of primary care physicians in Baden-Wuerttemberg and Bavaria with regard to TBE vaccination and prevention of TBDs and to derive strategies for increasing vaccination rates and improving knowledge about TBE and other TBDs in the population and among primary care physicians. We invited all primary care physicians (N = 14,046) in both states to participate by mail. Using standardized, self-administered questionnaires, available both on paper and online, we asked physicians anonymously about their knowledge, attitudes and behaviors with respect to TBE vaccination and TBD prevention and their need for further information/educational materials. A total of 2321 physicians participated between May and September 2022 (response rate 17%), of whom 1222 (53%) worked in Baden-Wuerttemberg and 1067 (46%) in Bavaria. Among the participating physicians, 56% were male, 71% were >50 years and 51% worked in an individual practice. Furthermore, 91% were aware of the German national vaccination guidelines, and 98% perceived their knowledge of the risks and benefits of vaccination as adequate. A total of 97% offer TBE vaccinations, 67% provide vaccination counselling during initial consultations with new patients and 64% actively remind patients about due vaccinations. In addition, 24% expressed a need for further information materials, mainly traditional, analogue media such as flyers (82%) and posters (50%), and named timeliness, quality assurance, easy comprehensibility and independence from the pharmaceutical industry as the most important characteristics of such materials. Almost all participating physicians reported offering TBE vaccinations and feeling well-informed about TBE vaccination and TBDs. However, active offering of vaccinations and education could be further improved, and additional, low-threshold information materials are needed. Based on these results, we will develop and provide various materials on TBE vaccination and TBDs, in particular flyers and posters, for use by physicians during consultations.

Abstract
Vaccine acceptance by parents and caregivers remains a public health challenge that can potentially be addressed via community-based strategies. Such strategies might augment current vaccine hesitancy interventions occurring within medical homes. This article reviews the key challenges and advantages of evidence-based community strategies for overcoming parent/caregiver vaccine hesitancy, specifically (1) community-participatory vaccine hesitancy measurement, (2) communication approaches, (3) reinforcement techniques (eg, incentives, mandates), and (4) community-engaged partnerships (eg, vaccine champion training, vaccination in community settings). This article also discusses important considerations when vaccinating children and adolescents in non-primary care settings (school-based health centers, pharmacies, community events).

The Healthy, Immunized Communities Study: A pilot intervention to increase parents' intentions to get vaccines for their middle school children. Vaccine X 2023; 13:100273. [PMID: 36874634 PMCID: PMC9978848 DOI: 10.1016/j.jvacx.2023.100273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 12/20/2022] [Accepted: 02/09/2023] [Indexed: 02/13/2023] Open
Abstract
Pennsylvania shortened the provisional period for student vaccine compliance in 2018. We pilot tested a school-based health education intervention, The Healthy, Immunized Communities Study, to improve parents' intentions to get school-required (tetanus, diphtheria, acellular pertussis [Tdap]; and meningococcal conjugate [MCV]) and recommended (human papillomavirus [HPV]) vaccines for their children. In Phase 1, we partnered with the School District of Lancaster (SDL) to conduct four focus groups with stakeholders (local clinicians, school staff, school nurses, and parents) to inform the development of the intervention. In Phase 2, we randomized four middle schools in SDL to either the intervention (six email communications and school-community educational event) or control group. Seventy-eight parents took part in the intervention and 70 joined the control group. Vaccine intentions were compared within and between groups from baseline to 6-month follow-up with generalized estimating equations (GEE) models. Compared to the control, the intervention did not increase parents' vaccine intentions for Tdap (RR = 1.18; 95 % CI:0.98-1.41), MCV (RR = 1.10; 95 % CI:0.89-1.35), or HPV (RR = 0.96; 95 % CI:0.86-1.07). Among intervention participants, only 37 % opened ≥ 3 email communications and 23 % attended the event. Intervention participants reported high satisfaction with email communications (e.g., informative = 71 %) and felt that the school-community event met their educational objectives on key topics (e.g., immune system = 89 %). In conclusion, although we observed no intervention effect, our data suggest that this could be a result of the low uptake of intervention components. Further research is needed to understand how school-based vaccination-focused interventions can be successfully implemented with high fidelity among parents.

Critical success factors for high routine immunization performance: A case study of Senegal. Vaccine X 2023; 14:100296. [PMID: 37113739 PMCID: PMC10126928 DOI: 10.1016/j.jvacx.2023.100296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 02/24/2023] [Accepted: 03/30/2023] [Indexed: 04/08/2023] Open
Abstract
Background The essential components of a vaccine delivery system are well-documented, but robust evidence is lacking on how policies and implementation strategies are operationalized to drive catalytic improvements in coverage. To address this gap, we identified success factors that supported improvements in routine immunization coverage in Senegal, especially from 2000 to 2019. Methods We identified Senegal as an exemplar in the delivery of childhood vaccines through analysis of DTP1 and DTP3 coverage data. Through interviews and focus group discussions at the national, regional, district, health facility, and community-level, we investigated factors that contributed to high and sustained vaccination coverage. We conducted a thematic analysis through application of implementation science frameworks to determine critical success factors. We triangulated these findings with quantitative analyses using publicly available data. Results The following success factors emerged: 1) Strong political will and prioritization of resources for immunization programming supported urgent allocation of funding and supplies; 2) Collaboration between the Ministry of Health and Social Action and external partners fostered innovation, capacity building, and efficiency; 3) Improved surveillance, monitoring, and evaluation allowed for timely and evidence-based decision making; 4) Community ownership of vaccine service delivery supported tailored programming and response to local needs; and 5) Community health workers spearheaded vaccine promotion and demand generation for vaccines. Conclusion The vaccination program in Senegal was supported by evidence-based decision making at the national-level, alignment of priorities between governmental entities and external partners, and strong community engagement initiatives that fostered local ownership of vaccine delivery and uptake. High routine immunization coverage was likely driven by prioritization of immunization programming, improved surveillance systems, a mature and reliable community health worker program, and tailored strategies for addressing geographical, social, and cultural barriers.

Abstract
Healthcare workers (HCWs) were the first population group offered coronavirus disease 2019 (COVID-19) vaccines in South Africa because they were considered to be at higher risk of infection and required protecting as they were a critical resource to the health system. In some contexts, vaccine uptake among HCWs has been slow, with several studies citing persistent concerns about vaccine safety and effectiveness. This study aimed to determine vaccine uptake among HCWs in South Africa whilst identifying what drives vaccine hesitancy among HCWs. We adopted a multimethod approach, utilising both a survey and in-depth interviews amongst a sample of HCWs in South Africa. In a sample of 7763 HCWS, 89% were vaccinated, with hesitancy highest among younger HCWs, males, and those working in the private sector. Among those who were hesitant, consistent with the literature, HCWs raised concerns about the safety and effectiveness of the vaccine. Examining this further, our data revealed that safety and effectiveness concerns were formed due to first-hand witnessing of patients presenting with side-effects, concern over perceived lack of scientific rigor in developing the vaccine, confidence in the body's immune system to stave off serious illness, and both a general lack of information and distrust in the available sources of information. This study, through discursive narratives, provides evidence elucidating what drives safety and effectiveness concerns raised by HCWs. These concerns will need to be addressed if HCWs are to effectively communicate and influence public behaviour. HCWs are key role players in the national COVID-19 vaccination programme, making it critical for this workforce to be well trained, knowledgeable, and confident if they are going to improve the uptake of vaccines among the general population in South Africa, which currently remains suboptimal.

Abstract
By the end of 2021, approximately 15% of U.S. adults remained unvaccinated against COVID-19, and vaccination initiation rates had stagnated. We used unsupervised machine learning (K-means clustering) to identify clusters of unvaccinated respondents based on Behavioral and Social Drivers (BeSD) of COVID-19 vaccination and compared these clusters to vaccinated participants to better understand social/behavioral factors of non-vaccination. The National Immunization Survey Adult COVID Module collects data on U.S. adults from September 26-December 31,2021 (n = 187,756). Among all participants, 51.6% were male, with a mean age of 61 years, and the majority were non-Hispanic White (62.2%), followed by Hispanic (17.2%), Black (11.9%), and others (8.7%). K-means clustering procedure was used to classify unvaccinated participants into three clusters based on 9 survey BeSD items, including items assessing COVID-19 risk perception, social norms, vaccine confidence, and practical issues. Among unvaccinated adults (N = 23,397), 3 clusters were identified: the "Reachable" (23%), "Less reachable" (27%), and the "Least reachable" (50%). The least reachable cluster reported the lowest concern about COVID-19, mask-wearing behavior, perceived vaccine confidence, and were more likely to be male, non-Hispanic White, with no health conditions, from rural counties, have previously had COVID-19, and have not received a COVID-19 vaccine recommendation from a healthcare provider. This study identified, described, and compared the characteristics of the three unvaccinated subgroups. Public health practitioners, healthcare providers and community leaders can use these characteristics to better tailor messaging for each sub-population. Our findings may also help inform decisionmakers exploring possible policy interventions.

Abstract
Introduction Respiratory infections like influenza and pneumococcus increase mortality, morbidity, hospitalisation risks and healthcare costs in people with type 2 diabetes which can be prevented by vaccinations. However, there is not much data regarding how many people with type 2 diabetes in India receive pneumococcal and influenza vaccinations. Methods This is a cross-sectional study conducted between March 2022 to May 2022 at a tertiary care centre in South India. Patients were interviewed through face to face questionnaire regarding awareness, knowledge of influenza and pneumococcal infections, availability and need of vaccines, vaccination status and the possible reasons for not receiving vaccines. Results A total of 388 patients were recruited in the study. Knowledge about influenza and pneumococcal infections were present only in 4.8% and 4.1% respectively. And 98.7% of patients had no awareness about the availability and need for vaccines. Only 0.5% and 0.7% of patients received influenza and pneumococcal vaccinations respectively. After counselling and spreading awareness, 76.2% of patients said that they would receive vaccination in the next visit. Also, 23.19% of the patients refused to take any vaccinations even after counselling. And 23.7% of patients feared complications after vaccinations. Conclusion Pneumococcal and Influenza vaccination uptake rates are extremely low in people with type 2 diabetes in India. Urgent measures are required to increase the awareness in patients and healthcare workers about the availability, need for vaccinations and effectiveness of vaccines which would lead to improvement in vaccination rates.

Abstract
OBJECTIVE To test the hypothesis that a feedback-based intervention would reduce human papillomavirus (HPV) vaccine missed opportunities. METHODS In a longitudinal cluster randomized controlled trial of 48 pediatric primary care practices, we allocated half the practices to receive a sequential, multicomponent intervention phased over consecutive periods. In a prior trial (period 1), communication skills training reduced missed opportunities for the initial HPV vaccine dose at well visits but not at acute/chronic visits. The current trial (period 2) evaluated the added value of performance feedback to clinicians after communication training. Performance feedback consisted of an introductory training module, weekly electronic "Quick Tips," and 3 individualized performance feedback reports to clinicians. We fit logistic regression models for the primary outcome of HPV vaccination missed opportunities using generalized estimating equations with independence working correlation, accounting for clustering at the practice level. RESULTS Performance feedback resulted in a 3.4 (95% confidence interval [CI]: -6.8, 0.0) percentage point greater reduction in missed HPV vaccine opportunities for the intervention versus control group during acute/chronic visits for subsequent HPV vaccinations (dose 2 or 3). However, during well visits for HPV vaccination dose #1, intervention practices increased missed opportunities (worsened) by 4.2 (95% CI: 1.0, 7.4) percentage points more than control practices, reducing the prior period 1 improvements and blunting the overall effect of performance feedback. We did not observe differences for the other visit/dose categories. CONCLUSIONS Performance feedback improved HPV vaccination for one subset of visits (acute/chronic, subsequent HPV vaccinations due), but not for well visits.

Abstract
The immunization schedule recommended by the U.S. Advisory Committee on Immunization Practices (ACIP) provides a structure for how 10 different vaccine series should be administered to children in the first 18 months of life. Progress toward US early childhood immunization goals has largely focused on measuring vaccination coverage at age 24 months. However, standard vaccination coverage measures do not reflect whether children received vaccine doses by recommended ages, or whether vaccines were given concomitantly, per the schedule. In this paper, we describe innovations in population-level measurement of immunization schedule adherence through quantifying vaccination timeliness and undervaccination patterns. Measuring vaccination timeliness involves comparing when children received vaccine doses relative to ACIP age recommendations. To assess undervaccination patterns, children's vaccination histories are analyzed to determine whether they were vaccinated consistent with the ACIP schedule. Some patterns, such as spreading out vaccines across visits, are indicative of parental hesitancy. Other patterns, such as starting all recommended series but missing doses, are largely indicative of other immunization services delivery challenges. Since 2003, at least 12 studies have used National Immunization Survey-Child, immunization information system, or integrated health plan data to measure vaccination timeliness or undervaccination patterns at national or state levels. Moving forward, these novel measures can be leveraged for population-based surveillance of vaccine confidence, and for distinguishing undervaccination due to parental vaccine hesitancy from undervaccination due to other causes. Broader adoption of these measures can facilitate identification of targeted strategies for improving timely and routine early childhood vaccination uptake across the United States.

Abstract
STUDY OBJECTIVE To explore drivers of suboptimal vaccination rates by understanding why parents without strong antivaccine beliefs do not fully vaccinate their children. METHODS Four focus groups were conducted in Washington state with 41 parents of children aged 24 to 48 months who delayed, declined, or missed some but not all vaccines. During the focus groups, parents were asked about reasons their child was undervaccinated, information that might address their concerns, and additional support they needed. Transcripts were analyzed using template analysis with deductive and inductive codes. RESULTS Focus groups identified multiple reasons for parents deciding to delay or decline vaccines for their children, including issues of individualism and control. The groups emphasized the impact of personal circumstances, such as changes in insurance, on whether children were vaccinated. Our data also shed light on the reasons that parents do vaccinate their children, including school vaccination requirements, negative experiences with vaccine-preventable diseases, and a family tradition of vaccinating. Focus group participants offered suggestions for improving vaccine communication with parents such as having more parent/patient-friendly vaccine information, providing forums to discuss their concerns, and offering vaccination information in advance of well-child appointments. CONCLUSIONS To achieve the full benefit of vaccines on individual and community health, we need better ways to address vaccine hesitancy and decrease barriers. We suggest that many hesitant parents would benefit from more dialog with health care providers about vaccines, more approachable educational materials, and enforcement of existing policies requiring vaccines in schools and childcare facilities.

Measurement of provider fidelity to immunization guidelines: a mixed-methods study on the feasibility of documenting patient refusals of the human papillomavirus vaccine. BMC Med Inform Decis Mak 2022; 22:339. [PMID: 36550466 PMCID: PMC9783975 DOI: 10.1186/s12911-022-02083-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 12/13/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Assessment and feedback is a common implementation strategy to improve healthcare provider fidelity to clinical guidelines. For immunization guidelines, fidelity is often measured with doses administered during eligible visits. Adding a patient refusal measure captures provider fidelity more completely (i.e., all instances of a provider recommending a vaccine, resulting in vaccination or refusal) and enables providers to track patient vaccine hesitancy patterns. However, many electronic health record (EHR) systems have no structured field to document multiple instances of refusals for specific vaccines, and existing billing codes for refusal are not vaccine specific. This study assessed the feasibility of a novel method for refusal documentation used in a study focused on human papillomavirus (HPV) vaccine. METHODS An observational, descriptive-comparative, mixed-methods study design was used to conduct secondary data analysis from an implementation-effectiveness trial. The parent trial compared coach-based versus web-based practice facilitation, including assessment and feedback, to increase HPV vaccination in 21 community-based private pediatric practices. Providers were instructed to document initial HPV vaccine refusals in the EHR's immunization forms and subsequent refusals using dummy procedure codes, for use in assessment and feedback reports. This analysis examined adoption and maintenance of the refusal documentation method during eligible well visits, identified barriers and facilitators to documentation and described demographic patterns in patient refusals. RESULTS Seven practices adopted the refusal documentation method. Among adopter practices, documented refusals started at 2.4% of eligible well visits at baseline, increased to 14.2% at the start of implementation, peaked at 24.0%, then declined to 18.8%. Barriers to refusal documentation included low prioritization, workflow integration and complication of the billing process. Facilitators included high motivation, documentation instructions and coach support. Among adopter practices, odds of refusing HPV vaccine were 25% higher for patients aged 15-17 years versus 11-12 years, and 18% lower for males versus females. CONCLUSIONS We demonstrated the value of patient refusal documentation for measuring HPV vaccination guideline fidelity and ways that it can be improved in future research. Creation of vaccine-specific refusal billing codes or EHR adaptations to enable documenting multiple instances of specific vaccine refusals would facilitate consistent refusal documentation.

Wang X, Feng Y, Zhang Q, Ye L, Cao M, Liu P, Liu S, Li S, Zhang J. Parental preference for Haemophilus influenzae type b vaccination in Zhejiang Province, China: A discrete choice experiment. Front Public Health 2022; 10:967693. [PMID: 36466507 PMCID: PMC9710483 DOI: 10.3389/fpubh.2022.967693] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 10/11/2022] [Indexed: 11/07/2022] Open
Abstract
Background China is the only country in the world that has not included the Haemophilus influenzae type b (Hib) vaccine in its National Immunization Program, making it more difficult to eliminate Hib-related diseases through Hib vaccination. It is necessary to study parental preferences for Hib vaccination to optimize vaccine promotion strategies in China. Objective This study aimed to investigate Chinese parental preference for five attributes of Hib vaccination, i.e., the place of origin, effectiveness, adverse event, doctors' recommendation, and the price of full vaccination when making a decision to vaccinate their children under 2 years old. Methods A cross-sectional survey was conducted in two cities in Zhejiang Province from November to December in 2020 using a discrete choice experiment (DCE). A mixed logit model was used to estimate participating parents' preference for Hib vaccination attributes included in the DCE. Subgroup analysis and probability analysis were also conducted to capture the heterogeneity and trade-off of parental preference for Hib vaccination. Results Data from 6,168 observations were included in the analyses. Parents of children are, on average, more likely to voice a positive preference for Hib vaccination. Such attributes of Hib vaccination as effectiveness and doctor's recommendation have a significant positive influence on parents' preference for Hib vaccination, while imported vaccines, adverse events, and the price of full vaccination have a significant negative influence on parents' preference. Parents with different demographic characteristics also existed heterogeneities in preference for Hib vaccination. Parents will make a trade-off on price if the Hib vaccine has a good performance on effectiveness and safety. Conclusion The study found that, regardless of the place of origin of the Hib vaccine, parents with children under 2 years old prefer to compromise on price if the vaccine has a better effectiveness and safety profile. A proactive recommendation from doctors would strengthen their willingness for Hib vaccination. These findings help aid the development of communication strategies with parents for Hib vaccination in China.

Adherence to Herpes Zoster (Shingles) Catch-Up Campaign at the Romagna Local Health Authority (Italy), a Multi-Center Retrospective Observational Study. Vaccines (Basel) 2022; 10:vaccines10101770. [PMID: 36298636 PMCID: PMC9611813 DOI: 10.3390/vaccines10101770] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 10/16/2022] [Accepted: 10/20/2022] [Indexed: 11/05/2022] Open
Abstract
Herpes Zoster (shingles) is an infection that occurs when varicella-zoster virus reactivates from the latent state. Incidence and severity of Herpes Zoster disease increase with age. Antiviral drugs are the elective treatment; however, prevention of disease reactivation through effective and safe vaccines is available in Italy out-of-pocket from age 65 onwards. The Romagna Local Health Authority (northern Italy) administered catch-up vaccinations in March–May 2022 for immunizations not performed during the COVID-19 pandemic. In this study, adherence rates to the catch-up campaign and recall activities adopted in two centers were investigated. The uptakes for only the catch-up vaccinations were 11.4% and 12.4%. Having suffered from Herpes Zoster or having family members who suffered from it would not seem to be drivers of increased uptake. Although sending text-messages to all involved patients was the main motivation for vaccine uptake (85.7–95.1%), word of mouth and web/news advertising also contributed to adoption in Center No. 2. In both centers, the need for greater synergy between public health departments and general practitioners to engage their patients emerged, as did the need for additional recall measures. Studying the main drivers of vaccine hesitancy, especially at the local level, can help in targeting campaigns and catch-up activities in order to achieve widespread acceptance.

Patient-Guided Talking Points to Address COVID-19 and General Vaccine Hesitancy. PHARMACY 2022; 10:pharmacy10050137. [PMID: 36287458 PMCID: PMC9611272 DOI: 10.3390/pharmacy10050137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 10/10/2022] [Accepted: 10/13/2022] [Indexed: 11/25/2022] Open
Abstract
Vaccination remains one of the most effective ways to limit spread of disease. Waning public confidence in COVID-19 vaccines has resulted in reduced vaccination rates. In fact, despite vaccine availability, many individuals choose to delay COVID-19 vaccination resulting in suboptimal herd immunity and increased viral mutations. A number of qualitative and quantitative studies have been conducted to identify, understand, and address modifiable barriers and factors contributing to COVID-19 vaccine hesitancy among individuals with access to vaccine. Vaccine confidence may be improved through targeted patient–provider discussion. More patients are turning to pharmacists to receive their vaccinations across the lifespan. The primary goal of this commentary is to share evidence-based, patient talking points, tailored by practicing pharmacists, to better communicate and address factors contributing to vaccine hesitancy and reduced vaccine confidence.

Abstract
BACKGROUND Maximizing uptake of SARS-CoV-2 vaccines among people in prison is essential in mitigating future outbreaks. We aimed to determine factors associated with willingness to receive SARS-CoV-2 vaccination before vaccine availability. METHODS We chose 3 Canadian federal prisons based on their low uptake of influenza vaccines in 2019-2020. Participants completed a self-administered questionnaire on knowledge, attitude and beliefs toward vaccines. The primary outcome was participant willingness to receive a SARS-CoV-2 vaccine, measured using a 5-point Likert scale to the question, "If a safe and effective COVID-19 vaccine becomes available in prison, how likely are you to get vaccinated?" We calculated the association of independent variables (age, ethnicity, chronic health conditions, 2019-2020 influenza vaccine uptake and prison security level), identified a priori, with vaccine willingness using logistic regression and crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS We recruited 240 participants from Mar. 31 to Apr. 19, 2021 (median age 46 years; 19.2% female, 25.8% Indigenous). Of these, 178 (74.2%) were very willing to receive a SARS-CoV-2 vaccine. Participants who received the 2019-2020 influenza vaccine (adjusted OR 5.20, 95% CI 2.43-12.00) had higher odds of vaccine willingness than those who did not; those who self-identified as Indigenous (adjusted OR 0.27, 95% CI 0.11-0.60) and in medium- or maximum-security prisons (adjusted OR 0.36, 95% CI 0.12-0.92) had lower odds of vaccine willingness than those who identified as white or those in minimum-security prisons, respectively. INTERPRETATION Most participants were very willing to receive vaccination against SARS-CoV-2 before vaccine roll-out. Vaccine promotion campaigns should target groups with low vaccine willingness (i.e., those who have declined influenza vaccine, identify as Indigenous or reside in high-security prisons).

Abstract
This technical report accompanies the recommendations of the American Academy of Pediatrics for the routine use of influenza vaccine and antiviral medications in the prevention and treatment of influenza in children during the 2022 to 2023 season. The American Academy of Pediatrics recommends annual influenza vaccination of all children without medical contraindications starting at 6 months of age. Influenza vaccination is an important strategy for protecting children and the broader community as well as reducing the overall burden of respiratory illnesses when other viruses, including severe acute respiratory syndrome-coronavirus 2, are cocirculating. This technical report summarizes recent influenza seasons, morbidity and mortality in children, vaccine effectiveness, and vaccination coverage, and provides detailed guidance on storage, administration, and implementation. The report also provides a brief background on inactivated and live attenuated influenza vaccine recommendations, vaccination during pregnancy and breastfeeding, diagnostic testing, and antiviral medications for treatment and chemoprophylaxis. Updated information is provided about the 2021 to 2022 influenza season, influenza immunization rates, the effectiveness of influenza vaccination on hospitalization and mortality, available vaccines, guidance for patients with history of severe allergic reactions to prior influenza vaccinations, and strategies to promote vaccine uptake.

Abstract
Vaccine hesitancy is a growing complex and multifaceted phenomenon. It encompasses a wide spectrum of context-dependent attitudes and beliefs. Multiple factors influence parental decision-making including knowledge, sources of information, risk perception, trust, and individual experiences among others. This review focuses on describing the most common reasons that contribute to vaccine hesitancy among parents. Social media and the Internet have been described as major elements that can negatively influence parental decision-making regarding vaccines. The next focus is describing effective interventions that clinical providers can apply. Nonconfrontational and open discussions along with trusting and strong relationships between parents and providers seem to create a solid foundation toward vaccine acceptance. In addition, motivational interviewing is a helpful tool that has proven to be effective during these discussions. Ultimately, an individualized approach tailored to a specific community will likely be most effective in addressing vaccine hesitancy.

Abstract
Despite disproportionately higher rates of morbidity and mortality from COVID-19 among Black and Hispanic adults in the United States, ethnoracial disparities in vaccination rates emerged rapidly. The objective of this quality improvement study was to rapidly develop and implement an equity-focused community outreach intervention that facilitated COVID-19 vaccine appointments. Using the Plan-Do-Study-Act model, this multipronged, primary care-based outreach intervention developed call/recall systems that addressed vaccine hesitancy and facilitated real-time vaccine scheduling. Through 5058 calls to 2794 patients, 1519 patients were successfully reached. Of the 750 patients eligible for vaccine scheduling, 129 (17.2%) had a vaccine appointment scheduled by the caller and 72 (9.6%) indicated a plan to self-schedule. Low confidence in the vaccine was the most cited reason for declining assistance with a vaccine appointment. Primary care practices may wish to consider introducing similar outreach interventions in the future to address ethnoracial inequities in vaccination distribution.

Abstract
BACKGROUND COVID-19 has led to disruption in routine immunization programs around the world. Effective strategies need to be developed to address the decline in vaccine coverage to avoid preventable disease outbreaks. Our study reports a 4-days campaign for the catching-up of missed vaccinations in children aged between 6 and 8 years, in Milan, Italy. METHODS The catch-up vaccination campaign (21st-24th of September 2021) involved children born in 2013, 2014 and 2015. These cohorts, if not already immunized, received the fourth dose of the Diphtheria-Tetanus-acellular Pertussis and Poliomyelitis vaccination (DTaPP4), the second dose of the Measles-Mumps and Rubella vaccination (MMR2) and Chickenpox, according to the Italian vaccine schedule. RESULTS 3,943 letters were sent to children with a missing vaccination. 1,315 children, 33% of expected, were vaccinated during the campaign. The 2015 cohort was the one that benefited most from the initiative, 955 children were vaccinated for a total of 1,864 doses administered. This has led to a significant increase of 20.0 percentage points (p.p.) in vaccination coverages for the fourth dose of DTaPP and the second dose of MMR. 214 children for the 2014 cohort and 146 for the 2013 cohort were vaccinated during the following days, these cohorts have been already called previously therefore the participation in the campaign and consequently the increase in vaccination coverages were less substantial. CONCLUSIONS This experience has demonstrated that a mass vaccination campaign could be a useful tool in catch-up strategies, even during the pandemic. It should be part of a bigger immunization program strategy that also includes efforts to simultaneously strengthen routine immunization services. With the appropriate organizational improvements, this initiative could pave the way for future successful campaigns involving different age groups and vaccinations.

Abstract
INTRODUCTION Canadian correctional institutions have been prioritized for COVID-19 vaccination given the multiple outbreaks that have occurred since the start of the pandemic. Given historically low vaccine uptake, we aimed to explore barriers and facilitators to COVID-19 vaccination acceptability among people incarcerated in federal prisons. METHODS Three federal prisons in Quebec, Ontario, and British Columbia (Canada) were chosen based on previously low influenza vaccine uptake among those incarcerated. Using a qualitative design, semi-structured interviews were conducted with a diverse sample (gender, age, and ethnicity) of incarcerated people. An inductive-deductive analysis of audio-recorded interview transcripts was conducted to identify and categorize barriers and facilitators within the Theoretical Domains Framework (TDF). RESULTS From March 22-29, 2021, a total of 15 participants (n = 5 per site; n = 5 women; median age = 43 years) were interviewed, including five First Nations people and six people from other minority groups. Eleven (73%) expressed a desire to receive a COVID-19 vaccine, including two who previously refused influenza vaccination. We identified five thematic barriers across three TDF domains: social influences (receiving strict recommendations, believing in conspiracies to harm), beliefs about consequences (believing that infection control measures will not be fully lifted, concerns with vaccine-related side effects), and knowledge (lack of vaccine-specific information), and eight thematic facilitators across five TDF domains: environmental context and resources (perceiving correctional employees as sources of outbreaks, perceiving challenges to prevention measures), social influences (receiving recommendations from trusted individuals), beliefs about consequences (seeking individual and collective protection, believing in a collective "return to normal", believing in individual privileges), knowledge (reassurance about vaccine outcomes), and emotions (having experienced COVID-19-related stress). CONCLUSIONS Lack of information and misinformation were important barriers to COVID-19 vaccine acceptability among people incarcerated in Canadian federal prisons. This suggests that educational interventions, delivered by trusted health care providers, may improve COVID-19 vaccine uptake going forward.

Albers AN, Thaker J, Newcomer SR. Barriers to and facilitators of early childhood immunization in rural areas of the United States: a systematic review of the literature. Prev Med Rep 2022; 27:101804. [PMID: 35656229 PMCID: PMC9152779 DOI: 10.1016/j.pmedr.2022.101804] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 02/23/2022] [Accepted: 04/18/2022] [Indexed: 12/22/2022] Open
Abstract
Early childhood vaccination coverage is low in rural areas of the United States. Reminder-recall & positive family-provider relationships facilitate vaccine uptake. Parental hesitancy is a barrier to early childhood vaccination in the rural U.S. Vaccine referrals & distance to providers are also rural-specific barriers. To increase vaccine coverage, interventions across rural populations are needed.
Early childhood vaccination rates are lower in rural areas of the U.S. compared with suburban and urban areas. Our aim was to identify barriers to and facilitators of early childhood immunization in rural U.S. communities. We completed a systematic review of original research conducted in the U.S. between January 1, 2000-July 25, 2021. We searched PubMed, Cumulative Index for Nursing and Allied Health Literature, and Web of Science. We included studies that examined barriers to and facilitators of routine immunizations in children <36 months old in rural areas. Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we reported studies’ methodologies and targeted populations, definitions of rurality, and common themes across studies that reflected barriers to or facilitators of vaccination. Ultimately, 17 papers met inclusion criteria for review. The majority of studies (10/17) were conducted within one U.S. state, and the same number (10/17) were conducted prior to 2005. Facilitators of vaccine uptake in rural communities identified across studies included reminder/recall systems and parents’ relationships with providers. Parental hesitancy, negative clinic experiences, referrals outside of primary care settings, and distance to providers were identified as barriers to vaccination in rural settings. This review revealed a limited scope of evidence on barriers to and facilitators of early childhood immunization in rural communities. More investigations of the causes of low vaccine coverage and the effectiveness of interventions for increasing vaccine uptake are urgently needed in rural pediatric populations to address persistent rural–urban immunization disparities.
