Evidence from the North Macedonia mobile vaccination and public health advice caravan. Health Policy 2024; 139:104966. [PMID: 38101148 PMCID: PMC10788482 DOI: 10.1016/j.healthpol.2023.104966] [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: 06/20/2023] [Revised: 12/07/2023] [Accepted: 12/11/2023] [Indexed: 12/17/2023]
Abstract
Over three years since the first COVID-19 vaccine was approved, many countries still have suboptimal vaccination rates despite holding great amounts of vaccines. Overall, there is little evidence on which policies are more effective to encourage vaccination, particularly in countries where a large share of the population remains unvaccinated. In this study, we examine the effectiveness of a community-based intervention carried out in March 2022 in North Macedonia, a country with a large and persistent share of the population that remains unvaccinated. The intervention, spearheaded by the Ministry of Health and supported by the World Health Organization and UNICEF, consisted of a mobile caravan offering vaccination and public health advice to different locations across the country on different days. Results from our staggered difference-in-difference model show that the mobile vaccination caravan increased daily vaccination rates by 7.7 vaccines per 100,000 inhabitants during the three weeks after the day of the caravan visit. This corresponds to a 35 % increase with respect to pre-intervention vaccination rates. We estimate a cost-effectiveness of 25.4 US dollars (USD) per additional vaccination induced. These results point to mobile caravan vaccines as an effective and cost-effective strategy to increase COVID-19 vaccination rates, even in a context of persistently suboptimal uptake.

Domnich A, Grassi R, Fallani E, Costantini G, Panatto D, Ogliastro M, Salvatore M, Cambiaggi M, Vasco A, Orsi A, Icardi G. Increasing Influenza Vaccination Uptake by Sending Reminders: A Representative Cross-Sectional Study on the Preferences of Italian Adults. Vaccines (Basel) 2023; 11:1601. [PMID: 37897002 PMCID: PMC10610822 DOI: 10.3390/vaccines11101601] [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: 09/16/2023] [Revised: 10/10/2023] [Accepted: 10/14/2023] [Indexed: 10/29/2023] Open
Abstract
Evidence from countries that achieved a high seasonal influenza vaccination (SIV) coverage suggests that reminders to get vaccinated may increase SIV uptake. The goal of this study was to explore the experience and attitudes of Italian adults toward an active invitation to receive SIV, triggered by different sources and delivered via different communication channels, and to assess the projected benefits of this strategy. A cross-sectional survey on a representative sample of Italian adults was conducted by using computer-assisted web interviewing. Responses from 2513 subjects were analyzed. A total of 52.2% of individuals previously received invitations to undergo SIV and compared with people who did not receive any reminder were three times more likely (68.2% vs. 22.2%) to be vaccinated in the last season. Compared with other sources, reminders sent by general practitioners (GPs) were perceived as the most attractive. As for communication channels, most participants preferred text/instant messaging (24.6%) or email (27.2%), suggesting an acceleration in the Italian digital transformation triggered by the COVID-19 pandemic. Conversely, traditional postal letters or phone calls were preferred by only 17.0% and 8.6% of respondents, respectively. Reminders sent by GPs via text/instant messages or email are a valuable option for increasing SIV uptake among Italian adults.

Abstract
Objective To determine attitudes, behaviors, and intentions of university students regarding influenza vaccination.ParticipantsUndergraduate, graduate, and professional students enrolled at a private, midwestern university.Methods A 24-item electronic survey was designed and distributed after literature review and inputs from experts on immunizations. Bivariate tests were performed to observe differences between various subgroups of respondents (age, gender, race/ethnicity, housing, and academic program). Multivariate logistic regression was performed to find associations with their vaccination preferences.Results Of 3,267 complete responses (36.3% of total students), 75% reported obtaining influenza vaccination in 2016-2017. Vaccination rates were highest for Asian (81.0%) and lowest for Black students (59.6%). Health professional student vaccination rates of 89.3% were achieved with a vaccination mandate in place. Lowest immunization rates were identified for law (47.1%) and business (52.7%) students. Positive promotional factors were identified.Conclusions Access to free, on-campus vaccinations, mandates and promotional efforts are associated with high influenza vaccination rates.

Abstract
BACKGROUND China has low seasonal influenza vaccination rates among priority populations. In this study, we aimed to evaluate a pay-it-forward strategy to increase influenza vaccine uptake in rural, suburban, and urban settings in China. METHODS We performed a quasi-experimental pragmatic trial to examine the effectiveness of a pay-it-forward intervention (a free influenza vaccine and an opportunity to donate financially to support vaccination of other individuals) to increase influenza vaccine uptake compared with standard-of-care user-paid vaccination among children (aged between 6 months and 8 years) and older people (≥60 years) in China. Recruitment took place in the standard-of-care group until the expected sample size was reached and then in the pay-it-forward group in primary care clinics from a rural site (Yangshan), a suburban site (Zengcheng), and an urban site (Tianhe). Participants were introduced to the influenza vaccine by project staff using a pamphlet about influenza vaccination and were either asked to pay out-of-pocket at the standard market price (US$8·5-23·2; standard-of-care group) or to donate any amount anonymously (pay-it-forward group). Participants had to be eligible to receive an influenza vaccine and to have not received an influenza vaccine in the past year. The primary outcome was vaccine uptake. Secondary outcomes were vaccine confidence and costs (from the health-care provider perspective). Regression methods compared influenza vaccine uptake and vaccine confidence between the two groups. This trial is registered with ChiCTR, ChiCTR2000040048. FINDINGS From Sept 21, 2020, to March 3, 2021, 300 enrolees were recruited from patients visiting three primary care clinics. 55 (37%) of 150 people in the standard-of-care group (40 [53%] of 75 children and 15 [20%] of 75 older adults) and 111 (74%) of 150 in the pay-it-forward group (66 [88%] of 75 children and 45 [60%] of 75 older adults) received an influenza vaccine. People in the pay-it-forward group were more likely to receive an influenza vaccine compared with those in the standard-of-care group (adjusted odds ratio [aOR] 6·7 [95% CI 2·7-16·6] among children and 5·0 [2·3-10·8] among older adults). People in the pay-it-forward group had greater confidence in vaccine safety (aOR 2·2 [95% CI 1·2-3·9]), importance (3·1 [1·6-5·9]), and effectiveness (3·1 [1·7-5·7]). In the pay-it-forward group, 107 (96%) of 111 participants donated money for subsequent vaccinations. The pay-it-forward group had a lower economic cost (calculated as the cost without subtraction of donations) per person vaccinated (US$45·60) than did the standard-of-care group ($64·67). INTERPRETATION The pay-it-forward intervention seemed to be effective in improving influenza vaccine uptake and community engagement. Our data have implications for prosocial interventions to enhance influenza vaccine uptake in countries where influenza vaccines are available for a fee.

Abstract
BACKGROUND The burden of influenza is mostly felt by employees and employers because of increased absenteeism rates, loss of productivity and associated direct costs. Even though interventions against influenza among working adults are effective, patronage and compliance to these measures especially vaccination are low compared to other risk groups. AIMS This study was aimed to assess evidence of economic evaluations of interventions against influenza virus infection among workers or in the workplace setting. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guideline for systematic reviews was followed. Three databases, PubMed, Web of Science and EconLit, were searched using keywords to identify relevant articles from inception till 25 October 2020. Original peer-reviewed papers that conducted economic evaluations of influenza interventions using cost-benefit, cost-effectiveness or cost-utility analysis methods focused on working-age adults or work settings were eligible for inclusion. Two independent teams of co-authors extracted and synthesized data from identified studies. RESULTS Twenty-four articles were included: 21 were cost-benefit analyses and 3 examined cost-effectiveness analyses. Two papers also presented additional cost-utility analysis. Most of the studies were pharmaceutical interventions (n = 23) primarily focused on vaccination programs while one study was a non-pharmaceutical intervention examining the benefit of paid sick leave. All but two studies reported that interventions against influenza virus infection at the workplace were cost-saving and cost-effective regardless of the analytic approach. CONCLUSIONS Further cost-effectiveness research in non-pharmaceutical interventions against influenza in workplace settings is warranted. There is a need to develop standardized methods for reporting economic evaluation methods to ensure comparability and applicability of future research findings.

Abstract
Medicaid is a unique approach in ensuring the below poverty population obtains free insurance coverage under federal and state provisions in the United States. Twelve states without expanded Medicaid caused two million people who were under the poverty line into health insecurity. Principal Component-based logistical regression (PCA-LA) is used to consider health status (HS) as a dependent variable and fourteen social-economic indexes as independent variables. Four composite components incorporated health conditions (i.e., “no regular source of care” (NRC), “last check-up more than a year ago” (LCT)), demographic impacts (i.e., four categorized adults (AS)), education (ED), and marital status (MS). Compared to the unadjusted LA, direct adjusted LA, and PCA-unadjusted LA three methods, the PCA-LA approach exhibited objective and reasonable outcomes in presenting an odd ratio (OR). They included that health condition is positively significant to HS due to beyond one OR, and negatively significant to ED, AS, and MS. This paper provided quantitative evidence for the Medicaid gap in Texas to extend Medicaid, exposed healthcare geographical inequity, offered a sight for the Centers for Disease Control and Prevention (CDC) to improve the Medicaid program and make political justice for the Medicaid gap.

Abstract
BACKGROUND The Community Preventive Services Task Force (CPSTF) has recommended several interventions that have been demonstrated to be effective at increasing vaccination coverage. OBJECTIVE Conduct a systematic review to examine the costs of interventions designed to increase vaccination coverage among children and adolescents in the United States. DATA SOURCES PubMed, EconLit, Embase, and Cochrane. STUDY ELIGIBILITY, PARTICIPANTS, AND INTERVENTIONS Peer-reviewed articles from January 1, 2009 to August 31, 2019. APPRAISAL AND SYNTHESIS METHODS Studies were identified with systematic searches of the literature, reviewed for inclusion criteria, abstracted for data on intervention, target population, costs, and risk of bias. Cost measures were reported as costs per child in the target population, costs per vaccinated child, incremental costs per vaccinated child, and costs per vaccine dose administered. Results were stratified by intervention type, vaccine, and age group. RESULTS Thirty-seven studies were identified for full-text review. Across all interventions and age groups, the cost per child ranged from $0.10 to $537.38, and the incremental cost per vaccinated child ranged from $6.52 to $5,098.57. Provider assessment and feedback interventions had the lowest (median) cost per child ($0.17) and a healthcare system-based combined intervention with multiple components had the lowest (median) incremental cost per vaccinated child ($26.65). A community-based combined intervention with multiple components had the highest median cost per child ($537.38) and the highest median incremental cost per vaccinated child ($5,098.57). LIMITATIONS A small number of included intervention types and inconsistent cost definition. CONCLUSIONS There is substantial variability in the costs of CPSTF-recommended interventions.

Abstract
Background Annual influenza vaccination is recommended for all patients with cancer, but vaccine uptake data by cancer type and time since diagnosis are limited. We sought to estimate vaccination rates across different cancer types in the United States and determine whether rates vary over time since diagnosis. Methods Vaccination rates in individuals with solid tumor and hematological malignancies were estimated using data from 59 917 individuals obtained by the 2016 and 2017 National Health Interview Survey conducted by the Centers for Disease Control and Prevention. Results An average of 64% of the 5053 individuals with self-reported cancer received the influenza vaccine. Vaccination rates in men and women with solid tumors (66.6% and 60.3%, respectively) and hematological malignancies (58.1% and 59.2%, respectively) were significantly higher compared to those without cancer (38.9% and 46.8%, respectively). Lower rates were seen in uninsured patients, those younger than 45 years of age, and in African Americans with hematological malignancies but not with solid tumors. Vaccine uptake was similar regardless of time since cancer diagnosis. Conclusions Influenza vaccination rates are higher in men and women with cancer but remain suboptimal, highlighting the need for additional measures to improve vaccine compliance and prevent complications from influenza across all cancer types.

Abstract
The Mexican influenza vaccination program does not include a recommendation for people aged 50–59 years without risk factors for influenza complications, and there are limited data regarding the cost-effectiveness of vaccinating this population. To explore the clinical and economic effects of including this population in the vaccination schedule, we performed a cross-sectional epidemiological study using records (2009–2018) from Mexico’s Influenza Surveillance System (SISVEFLU), death records (2010–2015) from the National Mortality Epidemiological and Statistical System, and discharge and hospitalization records (2010–2015) from the Automated Hospital Discharge System databases. A 1-year decision-analytic model was used to assess cost-effectiveness through a decision-tree based on data from SISVEFLU. The primary outcome was influenza cases avoided; with associated influenza-related events as secondary outcomes. Including the population aged 50–59 years without risk factors in Mexico’s influenza immunization program would have resulted in 199,500 fewer cases; 67,008 fewer outpatient consultations; 33,024 fewer emergency room consultations; 33,091 fewer hospitalizations; 12 fewer deaths. These reductions equate to a substantial public health benefit as well as an economic benefit; yielding net savings of 49.8 million US dollars over a typical influenza season. Expansion of the current Mexican vaccination schedule to include these people would be a cost-saving and dominant strategy.

Abstract
Introduction: Many comparisons have been made on the effect and impact of COVID-19 on influenza pandemics of history. Therefore, it is reasonable to infer that the strategies utilized by healthcare providers to improve influenza vaccination rates can similarly be applied to the administration of a COVID-19 vaccine. The purpose of this study was to determine the rationale of low influenza vaccination rates in an urban allergy clinic and how to improve patient education and knowledge regarding the importance of influenza vaccination. A three-year comparison of interventions is presented as well as its application to future COVID-19 vaccinations. Methods: This study was performed at an outpatient allergy and clinical immunology practice (MSBI) with hospital affiliation in New York City, New York. A quality improvement medical committee was formed to optimize influenza vaccination rates to greater than 71% and established standardized protocols regarding patient intake workflows, vaccine counseling, and documentation. Patient records from four providers were used for this study to compare pre-and post-intervention rates. Results: 984 patients met inclusion criteria, with a normal distribution of ages (18-80), race, and sex. Average vaccination rates prior to the intervention were 9.25-13.60%. The average vaccination rate after the intervention was 91.34%. Discussion: The MSBI quality improvement study identified key areas to address in improving influenza vaccination rates. Vaccine hesitancy, public misinformation, and ambivalence surrounding vaccination with egg allergies or during a subcutaneous immunotherapy injection were all topics addressed during the 2018-2019 intervention year. Additional attention was also put toward provider education and standardization of documentation. Shared decision making and intensive education/outreach efforts are needed by physicians and patients alike to overcome vaccine hesitancy. In comparing this to upcoming COVID-19 vaccine challenges, similar barriers will likely also need to be addressed. Greater research is needed to understand patient motivations regarding hesitancy specific to the COVID-19 vaccine. Conclusion: As evidenced in the yearly battle with influenza and now the COVID-19 pandemic, it has become essential to identify and implement multi-level strategies to maximize vaccination rates, especially amid a global pandemic. With COVID-19 vaccines reaching emergency approval stages, it is important for healthcare providers to start creating workflows and strategies to address patient inquiries. The influenza vaccination quality improvement project presented here can be used as a guideline for future evaluations of COVID-19 vaccination efforts.

Does self-rated health status influence receipt of an annual flu vaccination? Prev Med 2020; 131:105949. [PMID: 31805314 DOI: 10.1016/j.ypmed.2019.105949] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2019] [Revised: 11/26/2019] [Accepted: 11/30/2019] [Indexed: 01/05/2023]
Abstract
Despite 79,400 deaths due to the influenza (flu) virus during the 2017-18 season, <50% of US adults receive an annual flu vaccination (AFV). Self-rated health status (SRH) is associated with health behavior utilization. The current study aims to determine if an association exists between an individual's SRH and their receipt of an AFV. In the 2017 US Behavioral Risk Factor Surveillance System survey, 39.1% of respondents had received a flu vaccination within the last 12 months. There was a statistically significant difference (p < 0.0001) between the vaccination rates of men (35.7%) and women (42.4%). There was a significant positive association between SRH and AFV for individuals who self-reported an SRH of either "Fair" (AOR 1.19; 95% CI 1.12-1.27) or "Poor" (AOR 1.24; 95% CI 1.14-1.35), compared to those reporting a status of "Excellent". For those reporting an SRH status of "Fair", there was a significant positive association for both men (AOR 1.20; 95% CI 1.10-1.32) and women (AOR 1.17; 95% CI 1.08-1.28). An association was also found for men (AOR 1.203; 95% CI 1.09-1.39) and women (AOR 1.23; 95% CI 1.09-1.399) who reported their SRH as "Poor". Only women showed a significant association (AOR 1.12; 95% CI 1.04-1.20) among those whose SRH was "Good". No association was found for individuals who reported SRH as "Very Good". These findings are of interest to health policy makers as they show there is still work required to convince individuals with a high SRH that they too need to receive an AFV.

Abstract
BACKGROUND The influenza virus caused 48.8 million people to fall ill and 79 400 deaths during the 2017-2018 influenza season, yet less than 50% of US adults receive an annual flu vaccination (AFV). Having health insurance coverage influences whether individuals receive an AFV. The current study aims to determine if an association exists between an individual's health plan type (HPT) and their receipt of an AFV. METHODS Data from the 2017 Behavioral Risk Factor Surveillance System and the optional 'Health Care Access' module were used for this study. The final study sample size was 35 684. Multivariable weighted and adjusted logistic regression models were conducted to investigate the association between HPT and AFV. RESULTS Medicare coverage was significantly associated with an increase in AFV for both men (adjusted OR (AOR) 1.62 (95% CI 1.28 to 2.06)) and women (AOR 1.28 (95% CI 1.00 to 1.53)). For men, other sources of coverage were also significantly positively associated with AFV (AOR 1.67 (95% CI 1.27 to 2.19)), while for women obtaining coverage on their own was significantly negatively associated with AFV (AOR 0.75 (95% CI 0.59 to 0.97)). CONCLUSION These findings are of interest to health policy makers as these show there are HPTs which are effective at improving vaccination rates. Adopting methods used by these HPTs could help the USA reach its Healthy People 2020 AFV coverage goal of 70%.

Abstract
INTRODUCTION Influenza infection causes significant morbidity and mortality in patients with cancer, and annual influenza vaccination for individuals with cancer is recommended. We sought to examine the documentation rate of influenza vaccine administration, refusal, or counseling in the first year after diagnosis of diffuse large B cell lymphoma (DLBCL) for patients across 3 hospitals in 2 health care systems. PATIENTS AND METHODS Documentation of vaccine administration, refusal, or counseling by physicians, advanced practice providers, or nursing staff during the first period of influenza vaccine availability after diagnosis (August to April) was assessed in medical records of patients diagnosed with DLBCL between February 2015 and October 2017 who presented to Emory St. Joseph Hospital (community hospital), Winship Cancer Institute of Emory University (academic medical center), or Grady Memorial Hospital (county hospital). RESULTS Of the 57% (61/107) of newly diagnosed patients with DLBCL who had vaccine-related documentation, 43% refused vaccination. Counseling was not documented for any patient. Inpatient nursing performed 75% of all documentation. Primary oncologists documented vaccination in 4% of all cases. CONCLUSION Despite the limited immunization documentation and high refusal rates observed in this study, the influenza vaccine refusal rate was lower than the average for the United States, the state of Georgia, and the previous studies of patients with cancer. Although routine outpatient vaccination occurs, improvements in screening, strategies for sharing patient vaccine-related information, and counseling of patients who refuse the vaccine are needed. Further work is also needed to determine the effectiveness of influenza vaccination in patients receiving anti-cancer therapy.

Letters designed with behavioural science increase influenza vaccination in Medicare beneficiaries. Nat Hum Behav 2018; 2:743-749.

Abstract
The influenza ('flu') vaccination is low cost1 and effective, typically reducing the likelihood of infection by 50-60%2. It is recommended for nearly everyone older than 6 months of age3; yet, only 40% of Americans are immunized each year. Vaccination rates are higher among at-risk groups, such as those ≥65 years of age, but still only 6 in 10 receive it4. There have been numerous attempts to improve vaccination rates using strategies such as school-based programmes, financial incentives and reminders, but these have generally had limited success5-7. Of the attempts that are successful, most are expensive-limiting scalability-and have not been evaluated in the elderly8. Conversely, lower-cost interventions, such as mailed information, hold promise for a scalable solution, but their limited effectiveness may result from how they have been designed. We randomly assigned 228,000 individuals ≥66 years of age to one of five versions of letters intended to motivate vaccination, including versions with an implementation intention prompt and an enhanced active choice implementation prompt. We found that a single mailed letter significantly increased influenza vaccination rates compared with no letter. However, there was no difference in vaccination rates across the four different letters tailored with behavioural science techniques.
