How to measure Organizational Vaccine Literacy: an exploratory cross-country survey

Abstract Background The project AcToVax4NAM (Grant No. 101018349-3° EU Health Programme) aims to ensure equal and guaranteed access to vaccination services for Newly Arrived Migrants (NAMs). The working group developed a tool that measured the level of Organizational Vaccine Literacy (OVL), defined as an organizational effort to make the Health System easier to access and navigate, thereby facilitating informed decision-making regarding vaccinations for individuals, families and communities. Methods A systematic literature review was undertaken to identify validated tools for measuring OVL, but none was found. Consequently, the review was broadened to include tools for assessing Organizational Health Literacy, which were then adapted to define OVL. A questionnaire consisting of 22 questions divided into 7 sections was developed, utilizing a scale of 1 to 5 to gauge OVL. The survey was then distributed among healthcare services in 8 countries of the AcToVax4NAM consortium. Results We received 88 responses, mainly from Italy (26%), Spain (23%) and Greece (12%), encompassing 17 facilities, primarily vaccination centers and health prevention departments. Questions about the clarity and easy access to vaccination information provided by organizations had high mean scores, except the questions on the navigability of websites for foreign patients (mean scores < 3). Notably, responses related to the issue of cross-sectoral collaboration between health services and other partners (e.g., patient associations, NGOs), had a mean score of 2.56. Low scores were observed in the area related to the perception of possible individual contribution to systemic organizational efforts. Conclusions Shifting to an approach in which organizations prioritize equity and address complex needs, rather than leaving it to individuals to navigate the complex world of healthcare providers, could bring benefits to population groups, particularly those at risk of not accessing prevention services, such as NAMs. Key messages • After conducting a systematic review to identify validated instruments for the measure of Organizational Vaccine Literacy (OVL), a tool consisting of 22 questions was developed to measure OVL. • Shifting to an approach where organizations prioritize equity and address complex needs, rather than leaving it to individual responsibility, could significantly benefit vulnerable population.

Driving policy changes: RISE-Vac lessons learnt and recommendations

Abstract The RISE-Vac project consortium applied evidence-based public health methods to collate, assess, and analyze all the evidence generated through project activities, including literature review and prospective data collection on quantitative and qualitative aspects of vaccine services implementation in prison settings. A multi-sectorial and inter-disciplinary group of experts was set-up including health professionals, statisticians, social scientists and people with lived experience from civil society organisations, health services, prison administrations, academia and international agencies. A set of recommendations, advice, and policy options on how to increase vaccine uptake, targeted to people in prison and using a citizen-centred approach, were developed and tailored to specific needs profiles of different prison population subgroups. Vaccinations to be considered in prison settings were grouped according to target population and/or public health objective into: Seasonal vaccinations and vaccination during outbreak; Childhood life-course vaccinations (booster doses); Vaccinations for cancer prevention; Vaccination for older population groups and people with chronic conditions. In consideration of the diversity of the countries participating in the project, their epidemiological context and available resources and infrastructures, a multi-tiered approach for the development and implementation of models for vaccination services implementation in prison settings was devised, encompassing core vaccinations, such as HBV, Flu, COVID-19 and tetanus, as well as expanded vaccination offer to respond to enhanced health needs and to promote equity of health outcomes, including e.g. HPV vaccination.

Vaccination Knowledge, Attitudes, Perceptions, and Educational Needs of Pharmacists in Singapore: A Cross-Sectional Study

Background: Singapore’s adult vaccination coverage is suboptimal, and this can be attributed to a lack of vaccination recommendations and misconceptions. Studies have explored pharmacists’ vaccination knowledge, attitudes, and practice behaviour overseas but limited information about pharmacists in Singapore is available. This study aims to investigate pharmacists’ vaccination knowledge, attitudes towards providing vaccination services, and their educational needs. Methods: A cross-sectional study was conducted on pharmacists in various practice settings using an anonymous online survey. Results: Pharmacists’ vaccination knowledge (median: 2; IQR: 1–3), confidence in providing vaccination services (median: 6; IQR: 5–8), and frequency of providing vaccination services (median: 2; IQR: 1–3) were only average. However, 74.3% of pharmacists agreed that they play an important role as vaccine advocates. Apparent differences in knowledge level (p = 0.008), confidence level (p = 0.001), attitude (p < 0.001), and the frequency of educating patients (p = 0.001) and recommending vaccinations (p < 0.001) were observed among pharmacists from different practice settings. The main barriers identified were discomfort with giving injections (38.5%) and a lack of skills or knowledge (28.3%) at the point of survey. Conclusions: Pharmacists see the importance of their role as vaccine advocates. However, their vaccination knowledge, confidence in providing vaccination services, and practice behaviours are only average due to inadequate training. Continuous professional education is required to increase pharmacists’ readiness to provide vaccination services.

Assessment of the first 5 years of pharmacist-administered vaccinations in Australia: learnings to inform expansion of services.

Cross-sectional study. We analysed data on pharmacist-administered vaccinations that were reported to the Australian Immunisation Register (AIR) between 2016 and 2019, categorised by gender, jurisdiction, age group and vaccine type. We conducted a national survey of community pharmacists providing vaccination services during June and July 2020 to understand how pharmacists record and report vaccinations to the AIR. We assessed data completeness by comparing the number of vaccinations reported by surveyed pharmacists to the number recorded on the AIR. 576 780 pharmacist-administered vaccinations were recorded on the AIR between 2016 and 2019, of which 94.7% were influenza vaccines. The proportion of vaccinations given by pharmacists increased each year, from <0.001% in 2016 to 2.7% in 2019. Between 2017 and 2019, rates of pharmacist-administered vaccinations were highest among people aged 60-64 years (2046 per 100 000 people) and those living in regional areas (1074 per 100 000 people). Among 243 survey respondents, 57.8% (126/223) reported vaccinations to the AIR automatically via software, 27.8% (62/223) manually entered data and 13.5% (30/223) used both methods. Of the 87 665 vaccination encounters recorded by 121 respondents, 82.2% (72 045/87 665) were recorded on the AIR. There were more AIR-recorded encounters from those who reported automatically via software (84.8% [49 309/58 134]) than from those who manually entered data (68.3% [12 127/17 746]). Pharmacists have an increasing role in providing vaccination services in Australia, with great potential to improve coverage among adults and populations in regional locations. Measures introduced during the COVID-19 pandemic may have increased the uptake of electronic methods of recording and reporting data, which can improve data completeness. Our results provide an assessment of the first 5 years of pharmacist vaccination services in Australia, against which future evaluations of the impacts of policy changes during the COVID-19 pandemic can be compared.

COVID-19 vaccine implementation at a syringe services program: experiences of frontline staff

BackgroundWhile people with substance use disorders, including people who inject drugs (PWID), experience increased risk for COVID-19 infection and adverse outcomes, COVID-19 vaccination rates among PWID are consistently lower than those observed in the general population. Offering COVID-19 vaccines at syringe services programs (SSPs) has been proposed as a critical strategy to increase vaccine uptake among this population. We explored the experiences of frontline staff at an SSP in Miami, Florida implementing onsite COVID-19 vaccines.MethodsBetween June and July 2022, we conducted in-depth semi-structured interviews with 17 staff members of an SSP in Miami, Florida. Data collection and codebook thematic analysis of transcribed interviews were guided by the Consolidated Framework for Implementation Research (CFIR).ResultsFacilitators and barriers of COVID-19 vaccine implementation at the SSP aligned with all major CFIR domains. Key facilitators included the SSP’s established partnership with the local health department for vaccine distribution, its existing funding sources which could be leveraged for vaccine-related expenses, consensus among staff about the need for new strategies to increase vaccine uptake among PWID, and PWID’s trust in the SSP. Major—but largely modifiable—barriers included lack of participant compensation, limited internal collaboration and communication regarding the vaccine initiative beyond implementation leads and innovation deliverers due to competing priorities and segmented roles and responsibilities, and insufficient involvement of the most participant-facing staff (i.e., the SSP’s peer navigators and outreach workers).ConclusionsImplementing onsite COVID-19 vaccines was perceived as feasible and acceptable by frontline staff at the SSP, however contextual factors impeded optimal implementation. Multilevel strategies, such as participant compensation for vaccine completion and internal educational meetings with staff to improve vaccine implementation and reach, are required. As a trusted source of preventative services for PWID, SSPs are an underutilized venue for increasing vaccine uptake among this population, and findings from this study could inform the expansion of low-barrier vaccine services at SSPs nationwide.

Pay more attention to vaccination to protect the health of the elderly

Vaccination has been implemented as a priority measure to control infectious diseases worldwide. The aging of the global population continues to intensify, and the process and level of aging in China are more prominent. As age increases, the immune function of people gradually declines, and the consequences of infectious diseases such as influenza, pneumococcal disease, and shingles are more severe in the elderly, which can exacerbate existing underlying diseases, leading to higher medical costs. In the process of achieving healthy aging, it is very necessary to protect vulnerable elderly people through vaccination. Despite the undeniable protective effects of the influenza, pneumococcal, and shingles vaccines for the elderly, coupled with excellent safety and significant health economic benefits, the current vaccination rates for these vaccines among the elderly in China remain low. Some factors, such as insufficient awareness of the necessity of vaccination, concerns about vaccine adverse reactions, lack of systematic and effective recommendations, and imperfect accessibility of vaccination services, affect the popularization of preventive vaccination among the elderly in China. This situation urgently calls for the attention of society as a whole, in order to maximize the role of vaccines in safeguarding the health of the elderly.

Uptake and correlates of influenza vaccine among older adults residing in rural regions of south China: a cross-sectional study.

Seasonal influenza continues to pose a substantial public health challenge for older adults residing in rural areas worldwide. Vaccination remains the most efficacious means of preventing influenza. This study aimed to investigate the extent of influenza vaccine coverage and identify the factors influencing vaccine uptake among older adults in rural regions of south China. A cross-sectional study utilizing convenience sampling was conducted in two rural sites in Guangdong Province. Individuals needed to meet specific inclusion criteria: (1) attainment of 60 years of age or older; (2) originating from rural households; (3) demonstrating a voluntary desire to partake in the survey, either through written or verbal informed consent. Data encompassed variables such as socio-demographic information, influenza infection and vaccination history, knowledge and attitudes toward influenza vaccination, and perceived beliefs regarding the influenza vaccine. Univariate and multivariable logistic regression analyses were employed to ascertain the factors associated with influenza vaccine utilization. In the multivariable model, adjustments were made for gender, age, legal marital status, highest educational attainment, and monthly income. A total of 423 participants were ultimately included in this study, with the majority falling within the age range of 60-75 years (81.3%). Only one-third of the participants had received an influenza vaccine in the past year (30.0%). Notably, nearly half of the older adults exhibited hesitancy toward influenza vaccination (45.1%). The multivariable analysis revealed that rural older people with a robust understanding of influenza vaccines and a positive attitude toward them (adjusted odds ratio [aOR] = 2.60, 95% confidence interval [CI]: 1.41-4.81), along with a high level of trust in vaccination service providers (aOR = 2.58, 95% CI: 1.01-6.63), were positively associated with receiving influenza vaccination in the past year. This study reveals a low rate of influenza vaccine uptake among older adults residing in rural areas of south China. Given the limited adoption of influenza vaccination and the significant threat it poses, there is an urgent imperative to devise precise interventions aimed at enhancing the effectiveness of influenza vaccination programs.

Expert consensus on the construction and improvement of adult vaccination service system at medical institutions

The "Healthy China 2030" plan outlines the goal of providing equitable, accessible, and continuous health services to achieve overall health for the population. However, with the increasing aging population in China, the burden of chronic non-communicable diseases and infectious diseases negatively impacts public health. The elderly population has high hospitalization rates due to infections from influenza virus, respiratory syncytial virus, and Streptococcus pneumoniae, which can even lead to death, posing a heavy economic burden on the healthcare system. Meanwhile, the prevalence of chronic diseases and multimobidity among adults are continuously rising, and infections could attack the high-risk groups which cause comlicaitons and severe outcomes. Vaccination is considered as most cost-effective measure for preventing infectious diseases, significantly reducing the disease burden on individuals while effectively controlling the spread of epidemics within the community. Currently, the adult vaccination service system in China is significantly lagging, making it difficult to fully utilize the health protection benefits of vaccines throughout the entire lifecycle. Therefore, to improve adult vaccination services and increase the vaccination rate among high-risk populations for severe diseases, this expert consensus analyzes the current status and challenges of adult vaccination services based on literature reviews and expert discussions. To provide suggestions for the establishment and improvement of adult vaccination service system, and reference health authorities and disease control and prevention departments to formulate relevant policies.

Vaccines and vaccination in prison settings: availability and model of service delivery in 20 European countries.

Prisons, due to various risk factors, are environments that are conducive to infectious disease transmission, with significantly higher prevalence of infectious diseases within prisons compared to the general population. This underscores the importance of preventive measures, particularly vaccination. As part of the international project "Reaching the hard-to-reach: Increasing access and vaccine uptake among the prison population in Europe" (RISE-Vac), this study aimed to map the availability and delivery framework of vaccination services in prisons across Europe and beyond. A questionnaire designed to collect data on the availability and delivery model of vaccination services in prisons was validated and uploaded in SurveyMonkey in July 2023. Then, it was submitted to potential participants, with at least one representative from each European country. Potential participants emailed an invitation letter by the RISE-Vac partners and by the European Organization of Prison and Correctional Services (EUROPRIS). Twenty European countries responded. Vaccines are available in European countries, although their availability differs by country and type of vaccine. The first dose is offered to people living in prisons (PLP), mostly within one month, COVID-19 is the most widely offered vaccine. In all countries, vaccines are actively offered by healthcare workers; in most countries, there is no evaluation of vaccination status among people who work in prison. The survey shows variance in vaccine availability for PLP and staff across countries and vaccine types. Quality healthcare in prisons is not only a matter of the right to health but also a critical public health investment: enhancing vaccine uptake consistently among PLP and staff should be prioritized.

Mobile Apps for Vaccination Services: Content Analysis and Quality Assessment.

Vaccination services are increasingly in demand by the public, and mobile apps are an effective tool to meet that demand. However, the characteristics and quality of these apps are unknown. Commonly used vaccination service apps on the market were surveyed with regard to quality, service content, and user experience to evaluate and guide users. The Qimai Data mobile app data analytics platform was used to search for common vaccination service apps by keyword, and the WeChat and Alipay platforms were searched for apps. The apps included in the study were independently evaluated by two reviewers using the Mobile Application Rating Scale, and the service content and user experience of the apps were analyzed. The intragroup correlation coefficient between raters was used to measure interrater reliability. In the app stores of the four major Android platforms and the iOS app store, 1092 and 207 apps were found, respectively; 189 WeChat applets and 30 Alipay applets were also found. A total of 29 apps was ultimately included in this study according to the inclusion criteria, including 21 independent apps, 4 WeChat applets, and 4 Alipay applets. Significant differences were found between independent apps and applets in terms of the quality score (t449.57=-5.301; P<.001) and the subjective quality score (z=-4.753; P<.001). No significant differences were found between iOS and Android platforms in terms of the quality score (t1404=-2.55; P=.80) and the subjective quality score (z=-0.137; P=.89). There was good intragroup consistency among the raters. In this study, independent apps and nonindependent apps that rely on social and payment platforms for implementation were included in the vaccination services category. The overall quality of these apps was acceptable. Nonindependent running apps were found to have slightly lower scores and showed room for improvement, and scores for the participatory apps were found to be generally low overall.

Media Literacy and Its Potential Influence on Mpox-Related Perceptions and Prevention Intentions in China During the 2022 Multi-Country Outbreak of Mpox

ABSTRACT Media literacy plays an increasingly important role in health communication during public health emergencies. The present study aimed to investigate the level of media literacy and its association with disease perceptions and behavioral intentions of receiving vaccination services among young men who have sex with men (YMSM) in China during the 2022 multi-country mpox outbreak. The data were from a large-scale cross-sectional survey conducted among 2,493 YMSM aged 18–29 years in six provincial regions in China in September 2022. A total of 2,079 YMSM who had obtained mpox information from social media platforms were included in this study. Correlation analysis and path analysis were conducted. The mean age of the sample was 24.7. After controlling for background variables, significant positive correlations were found in several pairs between media literacy, mpox-related perceptions (including perceived susceptibility to mpox, perceived severity of mpox, perceived benefits of mpox vaccination, and self-efficacy of receiving mpox vaccination), and the behavioral intention of receiving mpox vaccination. The mpox-related perceptions played a significant mediation role in the association between media literacy and intention of receiving mpox vaccination (indirect effect = 0.165, p < .001, effect size = 82.1%). Media literacy is crucial for developing disease perceptions during public health emergencies and may further influence the adoption of preventive measures. As social media platforms have become the main battle field of health communication during disease outbreaks, improvement of media literacy is urgently warranted.

Drivers of COVID-19 Vaccination among Eligible Adults in Abuja, Nigeria: A Mixed-Methods Study Using the WHO Behavioral and Social Drivers of Vaccination Framework.

Despite the availability of COVID-19 vaccines, Nigeria still faces significant COVID-19 vaccine hesitancy, with only 60.7% of the eligible population fully vaccinated as of 20 March 2023. Our study, part of a community-based effort to improve knowledge and uptake of the COVID-19 vaccine in the Gwagwalada Area Council of Abuja, the Federal Capital Territory (FCT) of Nigeria, utilized the WHO's Behavioral and Social Drivers (BeSDs)-of-vaccination framework to examine the drivers of COVID-19 vaccination among eligible adults. This was a mixed-method study with focus group discussions (FGDs) and in-depth interviews (IDIs) involving 40 purposively sampled participants. We triangulate qualitative findings with data from a household survey of 1512 eligible adults identified using a two-stage systematic cluster sampling approach. All data were collected from the 1-18 November 2022. The household survey showed 46% COVID-19 vaccine uptake, with Pearson chi-square and Fisher's exact test showing significant associations between vaccine uptake and gender, religion, and education. Multivariate logistic regression showed that confidence in vaccine safety, knowing vaccination sites and family/friends' endorsement of COVID-19 vaccination were the strongest items associated with vaccine uptake in the thinking-and-feeling, practical-issue, and social-process domains, respectively. Multiple items measuring these domains aligned with BeSD priority question, demonstrating the robustness of the pared-down framework. Qualitative data corroborated these findings. To address vaccine hesitancy and increase uptake, community-driven approaches to improve trust in vaccine safety and benefits and promote positive vaccination norms are needed. In addition, service delivery strategies to make vaccination services easily accessible and identifiable should be developed and tailored to community needs.

Risk factors of diphtheria outbreak in damt district of Al Dhalea Governorate, 2023 -Yemen: a case–control study

BackgroundIn Yemen, diphtheria has become an important health problem since 2017 when diphtheria re-emergence as a consequence of war and the collapse of the health system. In 2023, there has been a 57% increase in diphtheria cases compared to 2021 and 2022. Damt district of Al Dhalea Governorate had the highest reported cases for year 2023. The study aims to determine the risk factors associated with diphtheria outbreak in Damt District.MethodsA retrospective matched case–control (1:2) was used. All confirmed cases based on the WHO case definition reported from Damt district during 2023 were considered cases. Two age-matched (± 5years) neighborhood controls were recruited per case. A pretested questionnaire was used for collecting data during household interviews including demographic and household characteristics, knowledge of diphtheria, vaccination status, contact with a case of diphtheria, and travel history. Frequency and proportion for quantitative and median with interquartile range (IQR) for quantitative variables. Chi-square and Mann–Whitney tests to compare the distribution of categorical and numerical variables between cases and controls. Univariate and multivariate conditional binary logistic regression, and Adjusted Odds ratio (AOR) with a 95% confidence interval at P < 0.05 were used to identify risk factors.ResultsA total of 118 cases and 236 controls were enrolled, 56% were females (63% of cases vs. 53% of controls). The median (IQR) age was 14 (9,22) years for cases vs 12(7,23) of control, it was significantly higher for females than males in the case group: (16(10,29) Vs 10(6,18), P < 0.001) and control group: (15(8,25) vs 12(7,18), p-value = 0.022). Partial vaccination status AOR = 13.7(6.1–31.1), P-value < 0.001), contacts with a case of diphtheria AOR = 8.5(2.3–31.0), P value < 0.001) and Female gender, AOR = 3.3(CI; 1.1–9.5, P value = 0.029), were the main risk factors.ConclusionsPoor vaccination and contact with a case of diphtheria were the main contributors to diphtheria in the Damt district particularly among adult females. Increasing the vaccination coverage with a diphtheria-containing vaccine through routine immunization as well as tetanus-diphtheria vaccine for childbearing age females along with community awareness regarding protection measures during home care of diphtheria cases. Vaccination services as well as gender barriers related to Td vaccination should be investigated.

Assessing willingness to pay for children's COVID-19 vaccination among healthcare providers and users using a theory-based discrete choice experiment

Improving vaccine coverage among children is crucial to prevent the long-term consequences of COVID-19 infections and the emergence of resistant COVID-19 variants, especially in resource-scarce settings. This study determined factors influencing the willingness to take and pay for COVID-19 vaccine for children among Vietnamese healthcare professionals and the public. A Theory-Based discrete-choice experiment was focused on a different topic related to vaccines, including the COVID-19 vaccine for children, Monkeypox, the adult COVID-19 booster, the HIV vaccine, and a potential future pandemic. The recruitment period was from April to August 2022, and a total of 5700 Vietnamese individuals aged 16 and above from various regions of the country participated in the study. The data for the sub-study on the COVID-19 vaccination for children was completed by 891 of these participants. Most participants agreed on vaccination for all children. Among healthcare professionals it was 76.2% and 69.3% for the general population. Healthcare professionals were the main source of vaccine information (70.7%). Payment options of 50%, 100%, and full subsidy were the most popular. Concerns about vaccine characteristics were associated with lower acceptance among healthcare professionals and the general public. The burden of historical medical expenses negatively correlated with willingness to pay for vaccination, while service satisfaction positively correlated with willingness to pay. To develop an effective vaccination program among children in Vietnam, providing accurate information and satisfying vaccine services, primarily through knowledgeable and professional healthcare providers, can improve the willingness to vaccinate and pay for the COVID-19 vaccine.

Key stakeholder perspectives on delivery of vaccination services in Quebec community pharmacies.

Undervaccination is a public health issue that disproportionately affects underserved populations. Pharmacists are accessible health care professionals who have the potential to better reach communities. The aim of this study is to understand how organizational obstacles influence the pharmacist's ability to meet underserved clients' vaccination needs in community pharmacy. We conducted semi-structured interviews with key stakeholders in Quebec. Results were codified according to domains of the Consolidated Framework for Implementation Research. Fourteen interviews were carried out with representatives from pharmacy associations, pharmacy chains and banners, integrated health and social service centres, and local Quebec Public Health departments. Barriers to promoting vaccination were identified in four areas: 1) vaccine service logistics, 2) the pharmacy setting, 3) external influences and 4) pharmacist's knowledge and beliefs. Technological tools accessible to pharmacists are sufficient but not user-friendly due to the lack of integration between the pharmacy software, the vaccine registry and the provincial appointment system. Technology limits access to vaccination for certain underserved populations. Moreover, the incentives linked to vaccination do not favour the vaccination of difficult-to-reach clients and they limit pharmacists' ability to be proactive with vaccine recommendations. Pharmacists are more inclined to participate in mass vaccination campaigns, and delegating vaccine administration to nurses and technicians allows pharmacies to financially break even. Certain services such as travel health vaccination require an extended set of knowledge, which creates resistance for some pharmacists to integrate the role. Pharmacists are well-placed to improve vaccination uptake, but several technological and organizational barriers limit their ability to provide vaccination services and reach underserved communities. A better alignment between incentives and proactive promotion should be put forward to encourage pharmacists to actively identify and reach underserved populations.

Abstract A116: Cervical cancer awareness, knowledge, and attitudes in young adult students on a Northern California college campus

Abstract Cervical cancer is the fourth most common gynecological malignancy in women worldwide. Human papillomavirus (HPV) is the primary cause of cervical cancer, with increased risk associated with select serotypes HPV 16 and 18. This study assesses cervical cancer awareness, knowledge of HPV, and attitudes towards vaccination among a convenience sample of San Francisco State University (SFSU) students. Despite the availability of effective HPV vaccines and associated cervical cancer prevention, vaccine uptake remains relatively low which may be due to various factors, including lack of awareness and vaccine knowledge. A convenience sample survey assessing cervical cancer awareness, behaviors and attitudes about HPV vaccine was administered to students on the San Francisco State University campus. The data was collected anonymously, via QR code. Participants received a $10 Target gift card. At completion of the survey, a 5x7 information card about Cervical Cancer and HPV vaccines, developed by and for college students, was distributed to participants. A total of 100 students completed the survey. Participants average age was 23-24 years old; 60% of participants identified as female; 34% as male. The vast majority of participants were aware of cervical cancer. Among 60 female respondents, 25 (42%) reported having had a pap smear, but a larger proportion had not. Of the female participants over age 21 years old, 12 out of 62 had never had a pap smear. 39% of respondents were not aware of the HPV vaccine and its relationship to cervical cancer prevention. There was a large difference in HPV vaccine awareness by gender and age. Of the 60 female respondents, 20 had reported being unaware of the HPV vaccine, while 17 of the 34 male respondents also reported being unaware. At completion of the survey, two-thirds of respondents reported a plan to receive a pap smear as recommended. 16% said they will not, and 21% were unsure. Our survey set out to understand the distribution of knowledge, awareness, attitudes and behaviors about cervical cancer and HPV vaccination on the SF State college campus. We found that most students on our campus are aware of cervical cancer. However, a small proportion of participants eligible for pap smears have yet to undergo the procedure. Our research also revealed that there is a lack of understanding regarding the importance of HPV vaccination, with significant differences in awareness by gender and age. This study underscores the need for targeted educational initiatives on cervical cancer awareness, knowledge, and attitudes towards HPV and its vaccine. To improve awareness and preventive actions, we can; increase the efforts to educate the public about the importance of HPV vaccinations and regular Pap smears and improve access to vaccination and screening services. Addressing gaps in knowledge and negative impressions of HPV vaccine can lead to the ultimate eradication of CC as we know it. Citation Format: Elissa I. Sanders, Kim F. Rhoads, Suzana Beyene.

Abstract C176: Implementing HPV vaccination services in people living with HIV in Trinidad and Tobago: COVID-19 vaccination may have boosted HPV vaccination

Abstract Background: Globally, Caribbean countries are among the most heavily burdened by both HIV and cervical cancer (CCA). People living with HIV (PLWH) are more susceptible and vulnerable to cancer due to their immune-compromised status. There is a pressing need for clinic-based CCA prevention in PLWH. Objective: A preliminary quality improvement evaluation of the vaccination program targeting PLWH in Trinidad and Tobago from October 2018 to May 2024. Methodology: The electronic health information system from a large clinic was used to abstract HPV vaccination data. No personal identifiers were collected from the system to protect the privacy of individuals and abide by Trinidad and Tobago’s data protection law. Evaluation of quality improvement of interventions approach was applied. Descriptive analyses were conducted using SPSS. Results: A total of 5,615 PLWH were eligible to participate in the HPV Vaccination clinic from October 2018 to May 2024. The average age was 39.6 (age range: 18- 51); 51.4% were women and 48.6% were men. Most (81.7%) PLWH reported their sexual orientation was heterosexual. Among our participants, 62.4% were Afro-Caribbean, 18.6% were Mixed, and 7.4% were East Indian/Indian. The majority of PLWH completed at least secondary education (69.8%). Half were single (50.5%), and 42.1% were employed/self-employed. Among these HPV vaccine-eligible persons, 1,157 patients (20.6%) received HPV vaccines. For those who had received vaccines, 254 patients (22.0%) were vaccinated with at least 1dose of the HPV vaccine, 301 (26.0%) were vaccinated up to dose 2 HPV vaccine, and 602 (52.0%) were vaccinated up to dose 3 HPV vaccine. Importantly, of those who received the HPV vaccine, the rate of uptake varied for each year. The uptake of HPV vaccine from January to May 2024 was 10.5% and in 2023 it was 18.5%. The highest uptake was in 2021 which was 22.4% followed by that in 2022 which was 20.3%. Between 2018 and 2020, the uptakes were 13.7% for 2020, 12.1% for 2019, and 5.3% for 2018. Discussion: Overall, the HPV vaccination rate for PLWH was relatively low; only 1 in 5 was vaccinated. Still, we saw an interesting trend with the highest vaccination uptake during the peak years of COVID-19 vaccinations. Hence, our data suggest that the COVID-19 vaccination program may have boosted HPV vaccination. Given our lessons learned, our goal is to seek funding for an implementation and dissemination science approach for adopting, implementing, and sustaining clinic-based HPV-related cancer prevention by bundling services such as Pap-Testing, PSA testing and/or co-vaccination (e.g., flu, shingles) to improve reach and uptake towards reducing cancer-related morbidity and mortality among PLWH.

Analysis of health claims data on vaccination coverage in older adults in Bavaria, Germany: Influenza, pneumococcus and herpes zoster

BackgroundVaccination is essential, especially in older adults whose immune system function declines with age. The COVID-19 pandemic and its associated lockdowns temporarily disrupted routine vaccination services. We aimed to assess vaccination coverage for Influenza, Pneumococcus, and Herpes zoster among older adults in Bavaria over time and investigate potential pandemic effects on these rates. MethodsBased on health claims data from the Bavarian Association of Statutory Health Insurance Physicians (KVB), we estimated the percentage of adults aged 60 years and older vaccinated following the German Standing Committee on Vaccinations (STIKO) recommendation for Influenza (2012−2021), Pneumococcus (2017–2021) and Herpes zoster (2019–2021), stratified by sex and 10-year age groups. Using time series regression analysis, we estimated the effect of the pandemic period (2020−2021) on quarterly Influenza and Pneumococcal vaccination rates. ResultsIn the first year of the pandemic (2020), Influenza, Pneumococcus and Herpes zoster coverage in both sexes increased by 9.9, 8.7, and 2.5 percentage points (pp), respectively. In 2021, Influenza coverage decreased by 4.7 pp., while Pneumococcus and Herpes zoster coverage increased by 2.7 and 3.8 pp., respectively. Influenza and Pneumococcal vaccinations showed a seasonal pattern, with vaccinations occurring mainly in the fourth quarter; this pattern was distorted for Pneumococcus during the pandemic. Per the time series regression analysis, Influenza vaccination rates in the fourth quarters of 2020 and 2021 were 7.86 (95 %CI: 5.10–10.62) and 8.87 (95 %CI: 5.80–11.54) pp. higher for males and females, respectively, compared to that of the pre-pandemic period. During the pandemic, the quarterly Pneumococcal vaccination rates increased by 0.68 (95 %CI: 0.19–1.18) pp. in males and 0.80 (95 %CI: 0.30–1.30) pp. in females. ConclusionThe heightened increase in vaccination rates observed in 2020 may have resulted from increased vaccination awareness during the pandemic. As the pandemic effect wanes, more efforts are needed to sustain and increase these vaccination rates.

Improving access to tuberculosis preventive treatment for children in Ethiopia: designing a home-based contact management intervention for the CHIP-TB trial through formative research

BackgroundTuberculosis (TB) preventive treatment (TPT) is a long-standing recommendation for children exposed to TB but remains poorly implemented. Home-based contact management may increase access and coverage of TPT among children exposed to TB in their households.MethodsSixty in-depth interviews were conducted with key informants including program managers, TB providers (known as TB focal persons), health extension workers and caregivers whose children had recently engaged with TB prevention services in Oromia, Ethiopia in 2021 to understand the barriers and facilitators to providing home-based TB prevention services for children aged < 15 years. Thematic content analysis was conducted including systematically coding each interview.ResultsHome-based services were considered a family-centered intervention, addressing the time and financial constraints of clients. Stakeholders proposed a task-shared intervention between health extension workers and facility-based TB focal persons. They recommended that TB services be integrated into other home-based services, including HIV, nutrition, and vaccination services to reduce workload on the already overstretched health extension workers. Community awareness was considered essential to improve acceptability of home-based services and TPT in general among community members.ConclusionsDecentralization of TPT should be supported by task-sharing initiation and follow up between health extension workers and facility-based TB focal persons and integration of home-based services. Active community engagement through several existing mechanisms can help improve acceptability for both home-based interventions and TPT promotion overall for children.Trial registrationThe results presented here were from formative research related to the CHIP-TB Trial (Identifier NCT04369326) registered on April 30, 2020. This qualitative study was separately registered at NCT04494516 on 27 July 2020.

Colocation of COVID-19 Vaccination Services at Syringe Service Programs for People Who Inject Drugs and People Experiencing Houselessness in Oregon.

Integrating vaccination services with other essential health services could increase vaccination rates among socially marginalized populations. We examined the associations between colocation of vaccines at syringe service programs and COVID-19 vaccination status among people who inject drugs and people experiencing houselessness. This study included 1891 participants aged ≥18 years at 9 sites in Oregon from July 2021 through March 2022. Participants self-reported whether they had ever received ≥1 dose of a COVID-19 vaccine. We calculated site-level COVID-19 vaccine availability and overall vaccination rates. We compared site-level vaccination rates and analyzed the association between vaccine availability and vaccination status. We found no significant difference in vaccination rates between sites that did and did not offer COVID-19 vaccines (t7 = -0.33; P = .75). We also found no significant association between vaccine availability and vaccination status. However, the odds of having received a COVID-19 vaccine were 2.79 times higher for each additional site visit during which COVID-19 vaccines were available (odds ratio [OR] = 2.79; 95% CI, 2.18-3.58; P < .001). The association between vaccine availability and vaccine status was not moderated by participant age (OR = 1.03; 95% CI, 0.99-1.07; P = .13) or housing instability (OR = 0.59; 95% CI, 0.13-2.60; P = .48). Colocating COVID-19 vaccines at syringe service programs was only positively associated with vaccination status if vaccines were offered frequently on-site. Future work should examine whether the frequency of offering vaccination services increases willingness to engage in vaccination and examine trust and convenience as potential mechanisms.
