Influenza vaccine effectiveness in Ireland during two influenza seasons, 2022/23 and 2023/24

Abstract Background Live Attenuated Influenza Vaccine (LAIV) is recommended in Ireland for all children aged 2-17 years. Quadrivalent influenza vaccine is recommended for all others eligible for vaccination, including those aged ≥18 years with underlying medical conditions and all aged ≥65 years. We aimed to estimate influenza vaccine effectiveness (IVE) against Acute Respiratory Infection (ARI) presentations to primary care due to influenza over two influenza seasons in Ireland, to inform vaccination recommendations and communication campaigns. Methods We undertook a test-negative design case control study within the national sentinel surveillance General Practice network, as part of the European Vaccine Effectiveness Burden and Impact Studies (VEBIS) network. We compared influenza vaccination status among influenza Polymerase Chain Reaction (PCR) positive cases with influenza PCR negative controls, amongst patients consulting with ARI. We verified vaccination status using the national influenza vaccination database. We estimated end of season IVE for 2022/23, and mid-season IVE (up to 7th April 2024) for 2023/24, using multivariable logistic regression and adjusting for age, onset time, medical condition, and sex. Results In 2022/23, there were 288 cases and 765 controls. In 2023/24 there were 515 cases and 1,482 controls. Overall vaccination coverage was 23% in both seasons. Coverage in 2-17 year-olds was 10% in 2022/23 and 12% in 2023/24. In 2022/23, overall IVE was 42% (95%CI 9-54) and 50% (95%CI -30-83) in 2-17 year-olds. Overall IVE in 2023/24 was 37% (95%CI 16-54) and was 67% (95%CI 28-87) in 2-17 year-olds. Conclusions Influenza vaccination reduced medical attendance to primary care with ARI due to influenza, demonstrating benefits of vaccination, particularly among children. Influenza vaccination should continue to be offered and promoted to recommended groups, including children. Key messages • This study suggests that influenza vaccination protected population health and the health service from medical attendance to primary care with acute respiratory infection due to influenza. • Higher influenza vaccine effectiveness was observed in children aged 2-17 years. These findings can inform influenza vaccination programmes with LAIV for children in Ireland and internationally.

The evolution of vaccine mandates: from historical perspectives to contemporary applications

Abstract Luigi Sacco pioneered efforts in 19th-century Italian vaccination campaigns when mandatory vaccination practices began as a public health strategy. We bridge past and present through a systematic review of both historical and contemporary vaccine mandate policies. While Sacco’s early initiatives, characterised by compulsory vaccination and effective communication strategies, set foundational principles for vaccine mandates, the modern era, especially during the COVID-19 pandemic, has seen a significant shift in the nature and application of vaccine mandates. Recent legislative changes across various countries have introduced stricter mandates aimed at managing public health crises. For instance, Italy and France, deeply impacted by reduced vaccine uptake and subsequent measles outbreaks, responded by reinforcing vaccine mandates. These countries aimed to mitigate the dual challenges of achieving high vaccination coverage and combating growing vaccine hesitancy. Comparative analysis of recent legislative changes reveals a trend towards increasing coerciveness in vaccine mandates, reflecting a blend of functional and political pressures driving government decisions. This trend is evident in the legislative adjustments made in California, Australia, France, and Italy, where heightened penalties and reduced exemptions were introduced to counteract declining public compliance. The synthesis of these experiences highlights the critical role of robust, credible communication and the nuanced application of mandates that consider societal and cultural contexts. Contemporary strategies are characterised by targeted interventions aimed at specific populations, reflecting the complex interplay of social, political, and health dynamics in vaccine policy. The enduring relevance of vaccine mandates underscores the necessity of flexible, responsive public health strategies that effectively address both long-standing and emergent vaccine hesitancy and coverage challenges.

Estimating the impact of the COVID-19 vaccination programme in Ireland: December 2021-March 2023

Abstract Background In Autumn 2023, COVID-19 booster vaccines were offered to all those aged ≥50 years in Ireland. There was concern that vaccine fatigue would impact uptake. We aimed to quantify the direct impact of the COVID-19 vaccination programme on averted outcomes in individuals aged ≥50 years, during a period of Omicron variant dominance, to inform vaccination strategy and public health communication. Methods We conducted a retrospective observational study from December 2021 to March 2023 in Ireland. We considered as averted outcomes symptomatic SARS-CoV-2 presentations to primary care, emergency department (ED) presentations, hospitalisations, intensive care unit (ICU) admissions and deaths due to COVID-19. We used an adapted formula from other vaccine impact published studies, including national data on notified outcomes, vaccine coverage data and vaccine effectiveness (VE) estimates, sourced from the WHO’s live systematic VE review, to estimate the count and prevented fraction of outcomes in ≥ 50-year-olds averted by the COVID-19 vaccination programme. The number of expected outcomes in the absence of vaccination was calculated by summing the counts of outcomes observed and outcomes averted. Results Between December 2021 and March 2023, the COVID-19 vaccination programme averted 48,551 symptomatic presentations to primary care (36% of expected), 9,517 ED presentations (53% of expected), 102,160 hospitalisations (81% of expected), 3,303 ICU admissions (89% of expected) and 15,985 deaths (87% of expected). Conclusions During Omicron dominance, the COVID-19 vaccination programme averted symptomatic and severe outcomes, including deaths due to COVID-19, underscoring the benefits of COVID-19 vaccination. In the context of vaccine fatigue emerging as an important public health issue in Ireland and internationally, these findings can inform future COVID-19 booster vaccination programmes and communication about the reason for and importance of COVID-19 vaccination. Key messages • The COVID-19 vaccination programme in Ireland prevented illness and death in people aged ≥50-years. Vaccination therefore protected population health and the healthcare system. • These findings can be used to inform future COVID-19 vaccination policies, planning for winter, pandemic preparedness and communisation about the importance of ongoing COVID-19 vaccination programmes.

Transferability of vaccination interventions from a community perspective: One size does not fit all

Abstract Background Removing health system barriers to childhood vaccination is an urgent matter in the migrant community in Greece, the Turkish and Moroccan communities in the Netherlands, the Ukrainian minority in Poland, and the marginalized Roma community in Slovakia. The objective of this study was to select and adapt potentially transferable evidence-based interventions for HPV and MMR vaccine uptake in partnership with the underserved communities. Methods Using a participatory approach, we assessed transferability of six pre-selected interventions with the Population, Intervention, Environment and Transfer (PIET-T) models: All countries investigated two interventions with trained community members to support vaccination as health promoters. Greece and the Netherlands included a school-based vaccination program. The Netherlands added two interventions addressing providers’ HPV vaccine communication, and Slovakia a multilevel intervention. Results We identified barriers and facilitators for successful intervention transfer in each of the target contexts. The transferability analysis showed that an intervention with health promoters is potentially transferable with adaptations in all countries. Principles of trust in the educator, tailored and trustworthy information, help in navigating the health system for vaccination and easy access at no cost are transferable key elements in all contexts. Adaptations refer to the intervention elements that need to be tailored to specific contextual needs. School-based vaccination was nowhere transferable. Health provider training needs to be culturally sensitive and adapted to the Dutch system. The multilevel intervention in Slovakia is not fully transferable. Conclusions Participatory transferability analysis was essential for decision-making and intervention adaptation. All countries independently selected a health promoter intervention as having potential to remove the identified health system barriers in the respective context.

Developing HPV Vaccination Communication Strategies: Assessing Knowledge, Attitudes, and Barriers Among Healthcare Professionals in Kazakhstan

Background: Cervical cancer, predominantly caused by human papillomavirus, remains a major public health issue globally and in Kazakhstan, where it ranks among the most common cancers in women. A pilot HPV vaccination programme in Kazakhstan was suspended in 2017 due to mass parental refusals, and it is planned to be restarted in the coming years. This study aims to assess the knowledge, attitudes, barriers, and sources of information about HPV and the HPV vaccine among healthcare professionals in Kazakhstan. Methods: A cross-sectional study (December 2022–May 2023) involving 1189 healthcare professionals in Kazakhstan used a self-administered questionnaire. Statistical analysis included descriptive statistics, mean knowledge score, between-group comparisons, and binary logistic regression to identify factors linked to higher knowledge and vaccine recommendation. Results: The study found that the average knowledge score for HPV and the HPV vaccine among participants was 11 out of a possible 18. Correct answers to the questionnaire were observed more frequently among physicians than among nurses (p < 0.001). In our study, 72.6% of healthcare professionals expressed a positive intention to recommend the HPV vaccine. The likelihood of recommending the HPV vaccine was significantly higher among those with higher knowledge of HPV and its vaccine (OR 1.8; 95% CI 1.3–2.5; p < 0.001), those familiar with cervical cancer patients (OR 2.0; 95% CI 1.5–2.8; p < 0.001), and those with positive attitudes towards the COVID-19 vaccine and childhood vaccination (OR 2.3 and 1.5, respectively). Healthcare professionals identified key barriers to HPV vaccination, including public mistrust (49.4%), fear of side effects (45.9%), and insufficient knowledge among healthcare professionals themselves (30.3%). Information from the internet, including articles and journals, was the most commonly used source of information, followed by social media and colleagues. Conclusions: The disparities identified call for a tailored, multifaceted communication strategy that addresses the diverse needs of health professionals to address the differences in awareness between different groups, in order to ensure successful implementation and coverage of HPV vaccination across Kazakhstan.

Communicating about COVID-19 Vaccines: A Qualitative Study on Preferences, attitudes, and Influences on Canadian Post-secondary Student Decisions to Get Vaccinated

Given the reasonably low COVID-19 vaccine rates (e.g., <60% fully vaccinated) among Canadian young adults (18–29), we sought to understand the factors that motivated this demographic to get vaccinated. Fifteen post-secondary students and graduates participated in semi-structured interviews about the type of health information they received during the pandemic, and their communication preferences. Analysis of interview data revealed four themes: (1) Participants had high science and health literacy which equipped them to identify and dismiss misinformation; (2) Participants expressed high trust in official sources which positively impacted their confidence in the vaccines; (3) Participants exhibited a low perceived risk from COVID-19 infection and got vaccinated for reasons beyond personal protection; and, (4) Participants responded best to communication that was targeted and tailored towards them. These themes form a foundation for effective vaccine communication campaigns targeted and tailored toward young adults, which is essential for acceptance of future vaccine recommendations.

Effect of oncology provider conversations on patients’ vaccination decision-making: Patient perspectives at a safety-net system.

266 Background: Low immunization rates among adults are associated with worse outcomes, particularly among immunocompromised individuals, such as those diagnosed with a cancer. To better understand vaccination communication and decision-making experiences among adult cancer patients treated at a safety-net system, we conducted structured interviews to: (1) explore patients’ perceptions of their oncology providers’ role in adult immunization, and (2) understand the potential factors that underlie patients’ hesitancy to receive vaccines. Methods: Parkland Health is the safety-net system for Dallas County, providing care for a primarily minority and un-/under-insured population. Cancer patients who had previously deferred or declined immunization participated in either in-person or telephone interviews in their preferred language (English/Spanish), using a structured 8-question interview guide. Questions centered on oncology providers’ role, vaccine hesitancy, and vaccine decision-making. Interviews averaged 12 minutes and were recorded for transcription. Aggregated interview responses were coded by question and interpreted through content analysis which noted frequency (i.e., times concept stated) and extensiveness (i.e., repetition across questions). Results: Thirteen patients were interviewed – 7 in English, 6 in Spanish. Patient’s perceived their oncology providers as highly important to their vaccination decision-making as they were: (1) more likely to get a vaccine if it is recommended by their provider (P2: Well, if the doctor hadn’t told me I wouldn’t have gotten vaccinated ; P3: If they didn’t recommend it, I would not get it ; P12: If they recommend it, it's worth looking into or thinking about ), and (2) identified their oncology provider as a preferred means for learning about vaccines (P8: Asking the doctor or the doctor communicating with us patients about a vaccine... in my personal opinion, I would say, go ahead and vaccinate me ). Patient-identified reasons for hesitancy included concerns about side effects (P2: “several people told me that is why we got cancer” ), fear of needles, previous negative experiences, and preference for alternative medicine approaches. Conclusions: Results from this preliminary study suggest that while patients may not initiate vaccination conversations with their oncology providers, they do identify their providers as influential in their decision-making. Oncology providers may not consider immunization as their primary responsibility but can be a primary source for effective vaccine communication in conjunction with the oncology care team. Findings from our patient interviews informed interventions in a quality improvement project to increase immunization uptake among cancer patients at our safety-net system.

Abstract B027: Adapting communication resources for clinic staff in a multisite FQHC to improve HPV vaccination encounters with Spanish-speaking parents of adolescents

Abstract Introduction: Adopting evidenced-based strategies (EBS) targeting clinic staff in safety-net settings can improve adolescent HPV vaccination rates. Still, adaptations of EBS are needed to reach racial/ethnic minority patients and families effectively. As part of a larger implementation study on HPV vaccination, we examined and addressed adaptation needs for HPV vaccine communication resources to support clinic staff serving Hispanic adolescent FQHC patients. Methods: In October 2022-January 2023, we partnered with a large multi-site FQHC in Los Angeles, CA to deliver two clinic staff trainings designed to i) improve HPV knowledge and communication strategies; and ii) discuss HPV vaccine workflow. Informed by the Practice Change Model, we completed baseline qualitative interviews with clinic team members (providers, clinic staff, and leadership) and provider and clinic staff surveys to inform the development, implementation, and adaptation of clinic staff training on HPV vaccine knowledge and communication strategies. We then conducted site visits and key-informant interviews with clinic staff immediately post-training. Notes from site visits and key-informant interviews were transcribed to identify potential barriers to adoption and opportunities for adaptation. Results: Baseline data indicated 95% of clinic staff identified as Hispanic and 94% reported speaking a language other than English. Notes from site visits and key-informant interviews with clinic staff indicated clinic staff identified the need for Spanish language messaging to communicate HPV and cancer prevention messages to monolingual Spanish families. As a result, we adapted Spanish-language messages from the 2023 Health Resources and Services Administration toolkit and American Cancer Society to develop a handout with scripts that address top concerns about HPV vaccination with monolingual Spanish-speaking parents of adolescents to that were identified from baseline data collection. Bilingual-bicultural staff then validated messages and confirmed cultural relevance. Developed materials were then presented to clinic leadership to review and suggest further refinement before delivering them to clinic staff. Discussion: Key-informant interviews and post-training site visits played an important role in identifying opportunities to adapt EBS designed to improve HPV vaccination among culturally diverse patients. To better serve diverse communities disproportionately impacted by HPV-associated cancers, clinic staff need resources with HPV vaccine communication messages available in languages that reflect the needs of their patient population.

Connect, collaborate and tailor: a model of community engagement through infographic design during the COVID-19 pandemic

BackgroundAcross the globe, racial and ethnic minorities have been disproportionately affected by COVID-19 with increased risk of infection and burden from disease. Vaccine hesitancy has contributed to variation in vaccine uptake and compromised population-based vaccination programs in many countries. Connect, Collaborate and Tailor (CCT) is a Public Health Agency of Canada funded project to make new connections between public health, healthcare professionals and underserved communities in order to create culturally adapted communication about COVID-19 vaccines. This paper describes the CCT process and outcomes as a community engagement model that identified information gaps and created tailored tools to address misinformation and improve vaccine acceptance.MethodsSemi-structured interviews with CCT participants were undertaken to evaluate the effectiveness of CCT in identifying and addressing topics of concern to underserved and ethnic minority communities. Interviews also explored CCT participants’ experiences of collaboration through the development of new partnerships between ethnic minority communities, public health and academic researchers, and the evolution of co-operation sharing ideas and creating infographics. Thematic analysis was used to produce representative themes. The activities described were aligned with the levels of public engagement described in the IAP2 spectrum (International Association for Public Participation).ResultsAnalysis of interviews (n = 14) revealed that shared purpose and urgency in responding to the COVID-19 pandemic motivated co-operation among CCT participants. Acknowledgement of past harm, present health, and impact of social inequities on public service access was an essential first step in establishing trust. Creating safe spaces for open dialogue led to successful, iterative cycles of consultation and feedback between participants; a process that not only helped create tailored infographics but also deepened engagement and collaboration. Over time, the infographic material development was increasingly directed by community representatives’ commentary on their groups’ real-time needs and communication preferences. This feedback noticeably guided the choice, style, and presentation of infographic content while also directing dissemination strategies and vaccine confidence building activities.ConclusionsThe CCT process to create COVID-19 vaccine communication materials led to evolving co-operation between groups who had not routinely worked together before; strong community engagement was a key driver of change. Ensuring a respectful environment for open dialogue and visibly using feedback to create information products provided a foundation for building relationships. Finally, our data indicate participants sought reinforcement of close cooperative ties and continued investment in shared responsibility for community partnership-based public health.

Factors that influence vaccination communication during pregnancy: provider and patient perspectives using the theoretical domains framework.

Vaccination during pregnancy is recommended but uptake is low and evidence on the topic is limited. This study aimed to identify the drivers of current behavior and barriers to change for health care practitioners (HCPs) and pregnant patients in Canada. This study is an in-depth qualitative investigation of the factors influencing HCPs' vaccination communication during pregnancy, as well as factors influencing pregnant patients' vaccination uptake in Canada using the Theoretical Domains Framework. Three data sources were used: (1) perinatal HCP interviews before COVID-19; (2) perinatal HCP interviews regarding vaccine communication after COVID-19; and (3) survey of pregnant or lactating women after COVID-19. Forty-seven interviews and 169 participant responses were included. Perinatal HCPs reported limited information on vaccine communication or difficulty keeping up-to-date (Environmental context and resources; Knowledge; Beliefs about capabilities). HCPs lacked confidence and struggled with lack of training to address vaccine hesitancy without alienating patients (Beliefs about capabilities; Skills). Pregnant or lactating women struggled with the amount of information they felt was imposed on them, had concerns about the perceived negative consequences of vaccination, and felt pressure to understand what was best for them and their babies (Knowledge; Beliefs about consequences; Social influences). Our study provides a theory-based approach to identify influencing factors that can be mapped to theory-based intervention components, improving the likelihood of intervention effectiveness. The study is the first step in adapting an existing intervention to improve vaccine communication during pregnancy, ultimately, increasing vaccination uptake. http://links.lww.com/IJEBH/A260.

Contributions and Impact of Health Communication Research to Vaccination Efforts and Acceptance

ABSTRACT Vaccines (a medical product) and vaccination recommendations (expert advice on who should receive, when, and how often) have grown in importance and prominence in the past 15 years, including because of a recent COVID-19 pandemic. This essay highlights contributions from vaccine and vaccination-related health communication research since 2010. This research has had significant impacts – that is, visible and discernible positive effects – on the ways health communication is undertaken broadly (e.g. at the campaign level) and at the health care provider-patient level (e.g. conversations with parents and patients regarding vaccine benefits, risks, and safety). As this essay illustrates, health communication research has resulted in greater use of formative research to guide vaccination campaign and education efforts, better identification and understanding of the factors behind vaccination delay and declination, and greater recognition that communication efforts can fail to achieve desired outcomes or generate unintended consequences. Health communication research has also documented the powerful influence of healthcare provider communication on parent and patient understanding and compliance with immunization recommendations. Importantly, this research has also shown the characteristics of provider-patient communication matter much. Healthcare providers must have or establish a high degree of trust, be well-versed in vaccine efficacy and safety, and be adept at using their personal experiences, information tailoring/personalization, and evidence-based communication strategies to increase the likelihood of success.

"Vaccinating your child during an emergency is more important than ever": a randomised controlled trial on message framing among Ukrainian refugees in Poland, 2023.

BackgroundSince February 2022, the start of the full-scale war in Ukraine, millions of women and children have fled the country. Vaccination of refugee children is important to protect this vulnerable population from disease.AimWe investigate the determinants of vaccination intention in refugee mothers from Ukraine residing in Poland and test the effect of three message frames.MethodsParticipants were randomised into either a control group or one of three intervention groups encouraging vaccination using a specific frame: (i) trust in the Polish health system, (ii) ease of access to vaccination or (iii) risk aversion. Primary outcomes were intention to vaccinate a child in Poland and clicking on a vaccination scheduling link.ResultsThe study was completed by 1,910 Ukrainian refugee mothers. Compared with the control group, the risk aversion message significantly increased vaccination intention (adjusted odds ratio (AOR): 2.35, 95% confidence interval (CI): 1.25-4.42) and clicking on the vaccine scheduling link (AOR: 1.53, 95%CI: 1.12-2.09). Messages around trust and ease of access did not have an effect. Important determinants of vaccination intention were perceived importance of vaccination (AOR: 1.12 95%CI: 1.01-1.25) and trusting vaccination information official health institutes (AOR: 1.40 95%CI: 1.06-1.83) and social media (AOR: 2.09 95%CI: 1.33-3.27).DiscussionUsing a risk aversion frame highlighting the vulnerability to infection that refugees face resulted in increased vaccination intention and clicks on a vaccination scheduler. Health workers who interact with Ukrainian refugees could use this frame in their vaccination communication.

Communicating COVID-19 vaccine information to Chinese communities in the UK: a qualitative study of their knowledge, information sources and trust

IntroductionIn late 2020, the COVID-19 vaccine acceptance rates of Chinese people living in the UK were estimated between 52% and 57%, significantly lower than that of the general population (76%)....

The importance of ‘dread risk’ for vaccine communication

ABSTRACT Background Perceptions of ‘dread risk,’ information source beliefs, and trust in these sources are important variables towards understanding vaccine attitudes. The main objective of this research was to learn the associations among these phenomena and, particularly, how these variables may impact our understanding of vaccine attitudes. Methods In the summer of 2020, a total of 336 (M age = 53.55; SD age = 18.58) participants answered an online Qualtrics survey about their ‘dread risk’ perceptions of vaccines, their information source beliefs (e.g. credible, easy-to-access, etc.), trust in information sources, and vaccine attitudes. Results Results suggest participants had generally low levels of negative vaccine attitudes (M = 3.27; SD = 1.40). Regression analyses to predict negative vaccine attitudes found ‘dread risk’ perceptions to be the most significant predictor (beta = .61, p < .001), over and above information source beliefs and trust in information sources (F (9, 320) = 75.07, p < .001; adjusted R 2 = .67). Age was also significantly and negatively correlated with ‘dread risk’ (r = -.22, p < .001). Conclusions Results suggest that vaccine communication efforts should continue to identify individuals’ ‘dread risk’ perceptions about vaccines and emphasize this content in messaging. Future research should aim to understand more about the relationships between negative vaccine attitudes, ‘dread risk’ perceptions, information source beliefs, and trust in information sources to better predict vaccine-related decisions, (in)actions, and to support effective vaccine communication.

COVID-19 vaccination and concerns regarding vaccine hesitancy after the termination of the zero-COVID policy in China: A nationwide cross-sectional study

ABSTRACT COVID-19 vaccine hesitancy remains prevalent globally. However, national data on this issue in the general population after the termination of the zero-COVID policy in China are limited. In March 2023, we conducted a nationwide cross-sectional survey among Chinese adults using a self-administered questionnaire. Descriptive statistics and multivariate logistic regressions were employed. Among 4,966 participants, 43.8% reported COVID-19 vaccine hesitancy following the end of the zero-COVID policy in China. Higher rates of vaccine hesitancy were associated with being married (married: OR 1.36, 95%CI 1.17–1.57; other marital status: OR 1.86, 95%CI 1.36–2.55), working in healthcare (OR 1.64, 95%CI 1.38–1.96), having both minors and older adults in the household (OR 1.45, 95%CI 1.20–1.75), having no minors and older adults in the household (OR 1.44, 95%CI 1.17–1.77), having chronic diseases (OR 1.42, 95%CI 1.23–1.64), experiencing adverse events post-vaccination (OR 1.39, 95%CI 1.19–1.61), and uncertainty about previous COVID-19 infection (OR 1.45, 95%CI 1.13–1.86). Conversely, participants who had received the influenza vaccine in the past three years (OR 0.62, 95%CI 0.54–0.72), had previously taken the COVID-19 vaccine (OR 0.44, 95%CI 0.32–0.59), and had higher confidence in vaccines (OR 0.63, 95%CI 0.60–0.67) were less likely to exhibit hesitancy. Our findings indicate a significant level of vaccine hesitancy, underscoring the urgent need for tailored public health strategies to address vaccine hesitancy and improve uptake post-zero-COVID policy in China. A comprehensive understanding of public concerns and related factors is essential for developing effective vaccine communication strategies.

Integrating youth participatory action research and health communication to inform youth and young adult covid-19 vaccine communication research.

COVID-19 vaccination rates remain lower among adolescents compared with adults. Youth participatory action research (YPAR) offers opportunities to inform youth vaccine communication at the local and population level. However, few studies have integrated systematic health communication research with YPAR. In the current study, a diverse team of paid high school interns, undergraduate student mentors and communication researchers in West Philadelphia YPAR programs developed a theory-informed communication survey to measure teen COVID-19 vaccine beliefs, information sources and behavior. The survey was distributed locally and informed youth-created vaccine campaign messages. In addition, YPAR-derived survey measures complimented a qualitative online elicitation survey with US young adults. Responses were coded using inductive content analysis, informing measures for a subsequent population-level study of young adults. This research followed protocols approved by an Institutional Review Board. Applying a YPAR framework elevated youth voices in the study development process. Communication theory and methods aided the development of survey studies to advance both local YPAR program objectives and population-level research. Future implications are discussed.

Addressing Missed Opportunities for Vaccination among Children in Hospitals: Leveraging the P-Process for Health Communication Strategies.

Addressing missed opportunities for vaccination requires a nuanced and context-specific approach. The five-step P-Process provides a robust framework to develop a clearly defined strategy that addresses social and behavioral drivers, integrates into existing health delivery systems, and facilitates collaboration with local experts. This approach allows teams to design, implement, monitor, and evaluate strategies to address public health issues. However, its specific application in vaccination communication programs remains relatively underexplored and under-documented. Our team designed a multi-pronged communication intervention aimed at enhancing vaccine uptake among hospitalized children in two tertiary hospitals in India and Nigeria. In the Inquiry stage, we conducted in-depth interviews with caregivers of hospitalized children to assess barriers to vaccination in a hospital setting. In the Strategic Development stage, we developed a blueprint for activities, identifying target audiences and communication channels and developing implementation plans. During the Create and Test stage, we brought together a range of stakeholders to co-develop a communication intervention through human-centered design workshops, after which we piloted the materials in both hospitals. We then Mobilized and Monitored progress of the activities to identify potential gaps that our materials did not initially address. Lastly, in the Evaluate and Evolve stage, we conducted in-depth interviews with healthcare workers and caregivers to measure outcomes and assess the impact on caregivers' decisions to vaccinate their hospitalized children. By following the P-Process for the design, caregivers reported that many of their concerns about vaccines were alleviated, and HCWs reported that they were able to communicate with caregivers more effectively about vaccination. By harnessing the power of the P-Process, researchers can forge a context-specific path towards impactful vaccination communication interventions, one step at a time.

Healthcare professionals’ perceptions of challenges in vaccine communication and training needs: a qualitative study

BackgroundHealthcare professionals (HCPs) can play an important role in encouraging patients and their caregivers to be vaccinated. The objective of this qualitative study was to investigate HCPs’ perspectives on challenges in vaccine communication and unmet training needs in this domain.MethodsSemi-structured interviews were conducted with 41 HCPs (mainly nurses and physicians) with vaccination roles (23 in England; 18 in France), gathering information on: (1) HCPs’ approach to vaccine conversations with patients; (2) Challenges of communicating about vaccines; (3) Vaccine-related training and learning resources available to HCPs, and; (4) HCPs’ training needs around vaccine communication.ResultsHCPs described a range of communication experiences that indicated insufficient time, information, and skills to confidently navigate difficult conversations with vaccine-hesitant patients. Communication skills were especially important to avoid conflict that could potentially damage the patient-provider relationship. Some HCPs interviewed had received communication training, but for most, this training was not specific to vaccination. Although general communication skills were transferable to vaccine conversations, most HCPs welcomed specific training and informational resources to support countering patients’ misconceptions or misinformation about vaccines.ConclusionsHCPs would benefit from training tailored to address vaccine communication with patients, and this should be part of a systemic approach that also provides time and space to have effective vaccine conversations.

"You can push these conversations, but don't push your patient away": healthcare learner perspectives on virtual simulation games as an educational approach to address vaccine hesitancy.

Vaccine hesitancy is a significant threat to public health. Healthcare providers (HCPs) can address hesitancy during routine patient conversations; however, few multidisciplinary education tools exist for HCPs to learn to engage in vaccine discussion especially considering new vaccine technologies such as mRNA vaccines. The objectives of this study were to explore HCP learners' experiences with COVID-19 vaccine communication, and qualitatively evaluate an online learning module composed of virtual simulation games (VSGs) which utilize the PrOTCT Framework for HCP vaccine communication. Three virtual focus groups were conducted from December 2022 to January 2023 with Canadian healthcare learners in nursing (N = 6), pharmacy (N = 9), and medicine (N = 7) who participated in a larger study measuring the effectiveness of the VSGs. Using a pragmatic approach, a qualitative thematic analysis was conducted using NVivo to identify themes and subthemes. A total of 22 HCP learners participated in this study and three key themes were identified. Across all three disciplines, participants expressed that (1) their prior education lacked training on how to hold vaccine conversations, resulting in uncomfortable personal experiences with patients; (2) the VSGs increased their confidence in holding vaccine conversations by providing novel tools and skills; and (3) participants also provided feedback to improve the VSGs which was implemented and supported the dissemination to all HCP professions. Although HCPs are a trusted source of vaccine information, participants in this study felt they received little training on how to engage in challenging conversations regarding COVID-19 vaccines. The introduction of the PrOTCT Framework and presumptive statements provided novel strategies for HCP to initiate vaccine conversations, especially considering new vaccine technologies and participants appreciated the emphasis on coping strategies and resilience. It is essential that HCP are provided both opportunities to practice managing these conversations, and tools and skills to succeed at an early point in their careers to prepare them for future roles in vaccine advocacy, delivery, and promotion.

Decalogue of best practices in vaccine communication between immunocompromised patients and healthcare professionals

Communication between health professionals and patients remains a challenge from the point of view of health education and health care.
