Attitudes, perceptions, and experiences of Western Australians towards vaccine safety surveillance systems following COVID-19 vaccines: A qualitative descriptive study.

OBJECTIVE: Concerns regarding adverse events following immunisation are a barrier to vaccine uptake. Health professionals use vaccine safety surveillance systems (VSSSs) to monitor vaccines and inform the public of safety data. With little known about public attitudes, perceptions, and experiences with VSSS, we examined them in the context of COVID-19 vaccinations in Western Australia. METHODS: Researchers conducted 158 qualitative interviews between March 2021 and May 2022 within the broader [name redacted] project. Data regarding VSSS were coded in NVivo using the deductive and inductive methods. RESULTS: Despite some not knowing about VSSS, participants expected follow-up post COVID-19 vaccination. Vaccine hesitant or refusing participants knew about VSSS and regarded these systems positively. Additional considerations concerned the reliability of data collected by VSSS. CONCLUSION: Perceptions of VSSS signal a lack of understanding about how these systems work. Future studies should further explore the public's understanding of VSSS, whether VSSS improves vaccine confidence, and how governments can better communicate to the public about VSSS. IMPLICATIONS FOR PUBLIC HEALTH: Lack of understanding of how VSSS operate may be stymying attempts to build public vaccine confidence. Healthcare providers and governments could build public knowledge and understanding of VSSS to mitigate concerns of adverse events following immunisation.

"Fighting the pandemic!" Western Australian pharmacists' perspectives on COVID-19 vaccines: A qualitative study.

BACKGROUND: In Western Australia, community pharmacists are authorized to administer a range of vaccines without a prescription. Since mid-July 2021, pharmacists can also administer Coronavirus Disease 2019 (COVID-19) vaccines. Little is known about how pharmacists think and feel about giving and receiving COVID-19 vaccines and how they discuss it with patients. AIM: This study aimed to explore Western Australian pharmacists' perceptions on being vaccinated with, administering, and communicating about COVID-19 vaccines. METHODS: Semi structured interviews were conducted with 20 pharmacists from metropolitan and regional areas of Western Australia across a two-week period in July and early August 2021. Interview transcripts were coded using NVivo 20 and data was thematically analyzed using the framework method. RESULTS: Most pharmacists (n = 16, 80 %) had received at least one dose of a COVID-19 vaccine. Some expressed difficulty accessing the vaccine while two unvaccinated pharmacists were hesitant to receive it due to concerns about vaccine development. The majority of pharmacists spoke positively about administering the vaccines, discussing perceived facilitators such as designated vaccination days but also perceived barriers such as inadequate financial reimbursement compared to other healthcare providers. Many pharmacists obtained their information from Australian government sources and training modules. Pharmacists were only passively promoting COVID-19 vaccines, with conversations mostly initiated by patients. Most pharmacists specified they would highlight the common side effects when administering the vaccine and would provide patients with written information. CONCLUSION: The majority of pharmacists were willing to administer and be vaccinated with COVID-19 vaccines. Since pharmacists play an important role in increasing vaccine uptake, governments should provide equitable reimbursement to pharmacists in line with other vaccinators such as General Practitioners. We welcome the recent resources produced by governments and pharmacy professional organizations to help pharmacists actively promote the vaccines since this work was undertaken.

West Australian parents' views on vaccinating their children against COVID-19: a qualitative study.

BACKGROUND: Australian children and adolescents were among the last local cohorts offered COVID-19 vaccines. Despite promising initial uptake, coverage subsequently plateaued, requiring further efforts to improve access and build parents' recognition of the importance of COVID-19 vaccination. We sought to understand West Australian (WA) parents' willingness to vaccinate their children to inform strategies for improving uptake at the time in which they were becoming eligible. METHODS: We undertook in-depth qualitative interviews with 30 parents of children aged 5-17 years from June - December 2021. During this period, children aged 12-15 years became eligible for vaccination; children aged 5-11 years became eligible shortly thereafter. Data were thematically analysed in NVivo. RESULTS: Most parents intended on vaccinating their children once eligible. Parents sought to protect their children, to protect the community, to resume travel, and to get back to "normal". They reflected that vaccination against key infectious threats is a routine activity in childhood. Some were concerned about the vaccine, particularly mRNA vaccines, being new technology or impacting fertility. "Wait-awhiles" wanted to see what other parents would do or were delaying until they felt that there was a higher risk of COVID-19 in WA. Most parents of younger children wanted their child to be vaccinated at the general practice clinic due to familiarity and convenience. Parents were particularly eager for clear and consistent messaging about vaccination of children and adolescents, including safety, importance, scientific evidence, and personal stories. CONCLUSION: For future pandemic vaccinations pertaining to children, governments and health officials need to address parents' concerns and meet their preferences for the delivery of the vaccine program to children and adolescents.

Parents' COVID-19 vaccine intentions for children under 5 years: Brief reflections from a qualitative study.

AIM: Australian authorities made COVID-19 vaccines available for children aged under 5 years old with serious comorbidities in August 2022. There is presently no universal programme for young children, but crucial to any rollout's success is whether parents are motivated and able to vaccinate. By examining parents' vaccine intentions, this study aims to inform current and future COVID-19 vaccine roll-outs for children aged under 5 years. METHODS: As part of the mixed methods project 'Coronavax: Preparing Community and Government' we interviewed 18 Western Australian parents of young children about their intentions in late 2021. RESULTS: Two thirds intended to vaccinate if and when they could, with one third intending to delay for reasons including risk and safety perceptions, fears about side effects and influence from their social networks. However, even those choosing to delay were waiting rather than refusing. CONCLUSIONS: To improve uptake, targeted messaging should emphasise that COVID-19 can be a serious disease in young children, with such messaging drawing on the reputability and esteem of scientific and technical authorities. Such messaging should be oriented towards parents of children with serious comorbidities at the present time. It will be important to emphasise that government vaccine recommendations are based on supporting families to protect their children and keep them healthy.

Lifting the curtains of silence: Patient perceptions towards needs and responsibilities in contributing to the prevention of healthcare-associated infections and antimicrobial resistance.

BACKGROUND: Beyond the use of policy and system-focused approaches, it has been established globally that patients can play a role in enhancing the health care landscape. However, efforts to meaningfully translate patient engagement strategies that promote participation by hospitalized patients in relevant infection prevention and antimicrobial stewardship activities have not yet been realized. This study mapped the key factors acting as barriers and facilitators of patient engagement using a theoretical framework to identify potential new approaches to promote engagement. METHODS: Semistructured interviews were conducted with 36 patients from 3 major hospitals in Sydney, Australia, in 2019. Transcripts were inductively analyzed, with the resulting themes categorized into the components of the Capability-Opportunity-Motivation-Behavior model. RESULTS: The themes regarding barriers to patient engagement with relevant infection prevention and antimicrobial stewardship activities were: (1) Capability: misunderstanding and knowledge gaps about antimicrobial resistance; (2) Opportunity: strong family/patient support networks and good relationships with nursing staff provide an opportunity to support engagement; (3) Motivation: those who have some level of understanding or experience see the benefit and are most likely to engage actively. CONCLUSIONS: Assuming patients are inclined to participate in efforts, a logical starting point would be to build awareness amongst patients and providers; however, education will not suffice. There needs to be a system and policy shift to ensure that patient engagement is recognized as a worthy endeavor.

COVID-19 vaccine knowledge, attitudes, and experiences of health care workers in Perth, Western Australia: A qualitative study.

INTRODUCTION: Health care workers (HCWs) faced an increased risk of Coronavirus Disease 2019 (COVID-19). Australia's COVID-19 vaccine rollout commenced in February 2021 to priority groups, including HCWs. Given their increased risk, as well as influence on patients' vaccine uptake, it was important that HCWs had a positive COVID-19 vaccination experience, as well as trusting the vaccine safety and efficacy data. METHODS: Semi-structured interviews were undertaken with 19 public- and privately-practicing HCWs in Western Australia between February-July 2021. Data were deductively analysed using NVivo 12 and guided by the Capability-Opportunity-Motivation-Behaviour model. RESULTS: 15/19 participants had received at least one COVID-19 vaccine. Participants were highly motivated, mostly to protect themselves and to get back to "normal", but also to protect patients. Many had a heightened awareness of COVID-19 severity due hearing from colleagues working in settings more impacted than Western Australia. Participants trusted the COVID-19 vaccine development and approval process; their histories of having to accept vaccines for work helped them to see COVID-19 vaccination as no different. Many recalled initially being unsure of how and when they'd be able to access the vaccine. Once they had this knowledge, half had difficulties with the booking process, and some were unable to access a clinic at a convenient location or time. Participants learnt about COVID-19 vaccination through government resources, health organisations, and their workplace, but few had seen any government campaigns for the wider public. Finally, most had discussed COVID-19 vaccination with their social network. CONCLUSION: HCWs in Western Australia demonstrated good knowledge about COVID-19 vaccination, with many reasons to vaccinate themselves and support the vaccination of others. Addressing the barriers identified in this study will be important for planning to vaccinate health workforces during future pandemics.

'Corona is coming': COVID-19 vaccination perspectives and experiences amongst Culturally and Linguistically Diverse West Australians.

BACKGROUND: Culturally and Linguistically Diverse (CALD) groups within high-income countries are at risk of being left behind by the COVID-19 vaccination rollout. They face both access and attitudinal barriers, including low trust in government and health authorities. OBJECTIVE: To explore perceptions and attitudes towards COVID-19 vaccination, as well as facilitators, barriers and strategies to promote uptake among CALD residents of Western Australia (WA), where there were almost no COVID-19 cases for 2 years. DESIGN AND PARTICIPANTS: Perth, WA's capital, was chosen as the state's study site because most of the state's CALD population lives there. Eleven semistructured in-depth interviews and three focus groups (with 37 participants) were conducted with CALD residents between August and October 2021. Thematic analysis was conducted, informed by the 'Capability', 'Opportunity', 'Motivation', 'Behaviour' model. RESULTS: CALD participants faced barriers including a lack of knowledge about COVID-19 and the vaccines, low self-rated English proficiency and education levels, misinformation, passive government communication strategies and limited access to vaccine clinics/providers. They were, however, motivated to vaccinate by the imminent opening of state and international borders, trust in government and healthcare authorities, travel intentions and the desire to protect themselves and others. CONCLUSIONS: Despite high levels of trust and significant desire for vaccines among CALD communities in Perth, current strategies were not meeting their needs and the community remains at risk from COVID-19. Tailored intervention strategies are required to provide knowledge, address misinformation and facilitate access to ensure uptake of COVID-19 vaccines-including for additional doses-amongst CALD communities. Governments should work with trusted CALD community members to disseminate tailored COVID-19 vaccine information and adequately translated resources. PATIENT OR PUBLIC CONTRIBUTION: The Wesfarmers Centre of Vaccines and Infectious Diseases Community Reference Group at Telethon Kids Institute consulted on this project in September 2020; Ishar Multicultural Women's Health Services consulted on and facilitated the focus groups.

Western Australian health care workers' views on mandatory COVID-19 vaccination for the workplace.

Background: Health care workers (HCWs) are at an increased risk of catching and spreading Coronavirus Disease 2019 (COVID-19) compared with the general community, putting health systems at risk. Several jurisdictions globally have mandated or are looking to mandate COVID-19 vaccines for this cohort, but little is known about the acceptability of this measure, especially in different contexts, and there is little qualitative data to explore nuance, depth, and the reasons behind HCWs' opinions. Methods: In-depth semi-structured qualitative interviews were undertaken with 39 HCWs in Western Australia (WA) between February-August 2021, ascertaining their views on the prospective introduction and implementation of mandates for COVID-19 vaccines. Data were thematically analysed using NVivo 20. Results: There was broad support for COVID-19 vaccine mandates for HCWs amongst our participants, but also different views about what such a mandate would mean (redeployment versus termination) and how it would impact the rest of the workforce. One vaccine hesitant participant said that mandates would be their prompt to get vaccinated. Other participants invoked an informal code whereby HCWs have an obligation to be seen to support vaccination and to protect public health more broadly. However, they also raised concerns about implementation and procedural and policy fairness. Conclusion: Policymakers should consider how to mobilise the informal code of health promotion and public health support if introducing mandates. They should also consider whether HCWs will bring the same attitudes and approaches to mandates for additional vaccine doses.

Efficacy of Digital Health Tools for a Pediatric Patient Registry: Semistructured Interviews and Interface Usability Testing With Parents and Clinicians.

BACKGROUND: Acute respiratory infection (ARI) in childhood is common, but more knowledge on the burden and natural history of ARI in the community is required. A better understanding of ARI risk factors, treatment, and outcomes will help support parents to manage their sick child at home. Digital health tools are becoming more widely adopted in clinical care and research and may assist in understanding and managing common pediatric diseases, including ARI, in hospitals and in the community. We integrated 2 digital tools-a web-based discharge communication system and the REDCap (Research Electronic Data Capture) platform-into the Pragmatic Adaptive Trial for Acute Respiratory Infection in Children to enhance parent and physician engagement around ARI discharge communication and our patient registry. OBJECTIVE: The objective of this study is to determine the efficacy and usability of digital tools integrated into a pediatric patient registry for ARI. METHODS: Semistructured interviews and software interface usability testing were conducted with 11 parents and 8 emergency department physicians working at a tertiary pediatric hospital and research center in Perth, Western Australia, in 2019. Questions focused on experiences of discharge communication and clinical trial engagement. Responses were analyzed using the qualitative Framework Method. Participants were directly observed using digital interfaces as they attempted predetermined tasks that were then classified as success, failure, software failure, or not observed. Participants rated the interfaces using the System Usability Scale (SUS). RESULTS: Most parents (9/11, 82%) indicated that they usually received verbal discharge advice, with some (5/11, 45%) recalling receiving preprinted resources from their physician. Most (8/11, 73%) would also like to receive discharge advice electronically. Most of the physicians (7/8, 88%) described their usual practice as verbal discharge instructions, with some (3/8, 38%) reporting time pressures associated with providing discharge instructions. The digital technology option was preferred for engaging in research by most parents (8/11, 73%). For the discharge communication digital tool, parents gave a mean SUS score of 94/100 (SD 4.3; A grade) for the mobile interface and physicians gave a mean usability score of 93/100 (SD 4.7; A grade) for the desktop interface. For the research data management tool (REDCap), parents gave a mean usability score of 78/100 (SD 11.0; C grade) for the mobile interface. CONCLUSIONS: Semistructured interviews allowed us to better understand parent and physician experiences of discharge communication and clinical research engagement. Software interface usability testing methods and use of the SUS helped us gauge the efficacy of our digital tools with both parent and physician users. This study demonstrates the feasibility of combining qualitative research methods with software industry interface usability testing methods to help determine the efficacy of digital tools in a pediatric clinical research setting.

COVID-19 vaccine Mandates: An Australian attitudinal study.

BACKGROUND: The rollout of vaccines against COVID-19 is prompting governments and the private sector to adopt mandates. However, there has been little conceptual analysis of the types of mandates available, nor empirical analysis of how the public thinks about different mandates and why. Our conceptual study examines available instruments, how they have been implemented pre-COVID, and their use for COVID-19 globally. Then, our qualitative study reports the acceptability of such measures in Western Australia, which has experienced very limited community transmission, posing an interesting scenario for vaccine acceptance and acceptability of measures to enforce it. METHOD: Our conceptual study developed categories of mandates from extant work, news reports, and legislative interventions globally. Then, our empirical study asked 44 West Australians about their attitudes towards potential mandatory policies, with data analysed using NVivo 12. RESULTS: Our novel studies contribute richness and depth to emerging literature on the types and varying acceptability of vaccine requirements. Participants demonstrated tensions and confusion about whether instruments were incentives or punishments, and many supported strong consequences for non-vaccination even if they ostensibly opposed mandates. Those attached to restrictions for disease prevention were most popular. There were similar degrees of support for mandates imposed by employers or businesses, with participants showing little concern for potential issues of accountability linked to public health decisions delegated to the private sector. Participants mostly supported tightly regulated medical exemptions granted by specialists, with little interest in religious or personal belief exemptions. CONCLUSION: Our participants are used to being governed by vaccine mandates, and now by rigorous lockdown and travel restrictions that have ensured limited local COVID-19 disease and transmission. These factors appear influential in their general openness to COVID-19 vaccine mandates, especially when linked explicitly to the prevention of disease in high-risk settings.

Does a major change to a COVID-19 vaccine program alter vaccine intention? A qualitative investigation.

BACKGROUND: On 8th April 2021, the Australian Technical Advisory Group on Immunisation (ATAGI) made the Pfizer-BioNtech (Comirnaty) vaccine the "preferred" vaccine for adults in Australia aged < 50 years due to a risk of thrombosis with thrombocytopenia syndrome (TTS) following AstraZeneca vaccination. We sought to understand whether this impacted COVID-19 vaccine intentions. METHOD: We undertook qualitative interviews from February - April 2021 before and after the program change with 28 adults in Perth, Western Australia. Using our COVID-19 vaccine intentions model, we assessed changes in participants' COVID-19 vaccine intention before and after the program change. Participants were classified as 1) 'acceptors': no concerns about COVID-19 vaccine safety, efficacy, access and would accept whatever vaccine is offered, 2) 'cautious acceptors': some concerns and would prefer a particular vaccine brand but would accept whatever is offered, 3) 'Wait awhile': for more data, easier access, for another vaccine brand, a greater perceived COVID-19 threat or until mandatory, or 4) 'refuser': no intention to vaccinate due to concerns about safety and/or efficacy. RESULTS: Before the change, 7/18 of those aged < 50 years were 'acceptors,' 10/18 were 'cautious acceptors' and 1/18 was 'wait awhile.' Overall, 14/18 participants had the same COVID-19 vaccine intention after the change; 4/18 became more concerned. For those aged ≥ 50 years and before the change, 5/10 were 'acceptors' and 5/10 were 'cautious acceptors.' After the change, 8/10 still had the same COVID-19 vaccine intention; 2/10 became more cautious. The major concern before the program change was COVID-19 vaccines having different vaccine efficacy; the concern pivoted to safety. CONCLUSION: The majority of participants were 'cautious acceptors' who intended on being vaccinated; many had this intention before and after the program change. The Australian government, health care providers and media need to better address COVID-19 vaccine concerns to assist those with COVID-19 vaccine intentions receive a vaccine.

Paediatric Active Enhanced Disease Surveillance (PAEDS) 2019: Prospective hospital-based surveillance for serious paediatric conditions.

INTRODUCTION: The Paediatric Active Enhanced Disease Surveillance (PAEDS) network is an Australian hospital-based active surveillance system employing prospective case ascertainment for selected serious childhood conditions, particularly vaccine preventable diseases and potential adverse events following immunisation (AEFI). This report presents surveillance data for 2019. METHODS: Specialist nurses screened hospital admissions, emergency department records, laboratory and other data on a daily basis in seven paediatric tertiary referral hospitals across Australia, to identify children with the conditions under surveillance. Standardised protocols and case definitions were used across all sites. In 2019, the conditions under surveillance comprised: acute flaccid paralysis (AFP; a syndrome associated with poliovirus infection), acute childhood encephalitis (ACE), influenza, intussusception (IS; a potential AEFI with rotavirus vaccines), pertussis, varicella-zoster virus infection (varicella and herpes zoster), invasive meningococcal and invasive Group A streptococcus diseases and two new conditions, Kawasaki disease and gram-negative bloodstream infections. An additional social research component continued to evaluate parental attitudes to influenza vaccination. RESULTS: PAEDS captured 2,701 cases for 2019 across all conditions under surveillance. Key outcomes of PAEDS included: contribution to national AFP surveillance to reach the World Health Organization reporting targets for detection of poliomyelitis cases; demonstration of high influenza activity in 2019 and influenza-associated deaths in ACE cases; identification of key barriers to influenza vaccination of children hospitalised for acute respiratory illness; reporting of all IS cases associated with vaccine receipt to relevant state health department; and showing a further reduction nationally in varicella cases. Enhanced pertussis surveillance continued to capture controls to support vaccine efficacy estimation. Invasive meningococcal disease surveillance showed predominance of serotype B and a reduction in cases nationally. Surveillance for invasive group A streptococcus captured severe cases in children. Monitoring of Kawasaki disease incidence and gram-negative bloodstream infections commenced. CONCLUSIONS: PAEDS continues to provide unique policy-relevant data on serious paediatric conditions using sentinel hospital-based enhanced surveillance. Keywords: paediatric, surveillance, child, hospital, vaccine preventable diseases, adverse event following immunisation, acute flaccid paralysis, encephalitis, influenza, intussusception, pertussis, varicella zoster virus, meningococcal, group A streptococcus, Kawasaki, bloodstream infections.

Barriers to influenza vaccination of children hospitalised for acute respiratory illness: A cross-sectional survey.

AIM: To identify barriers to influenza vaccination of children hospitalised for acute respiratory illness in Australia. METHODS: A total of 595 parents of children hospitalised with acute respiratory illness across five tertiary hospitals in 2019 participated in an online survey. Multivariate logistic regression identified factors most strongly associated with influenza vaccination barriers. RESULTS: Odds of influenza vaccination were lower with lack of health-care provider (HCP) recommendation (adjusted odds ratio (aOR) 0.18; 95% confidence interval (CI): 0.08-0.38); if parents had difficulties (aOR 0.19; 95% CI: 0.08-0.47) or were 'neutral' (aOR 0.23; 95% CI: 0.06-0.82) in remembering to make an appointment; and if parents had difficulties (aOR 0.21; 95% CI: 0.07-0.62) or were 'neutral' (aOR 0.24; 95% CI: 0.07-0.79) regarding getting an appointment for vaccination. Odds were also lower if parents did not believe (aOR 0.27; 95% CI: 0.08-0.90) or were 'neutral' (aOR 0.15; 95% CI: 0.04-0.49) regarding whether the people most important to them would have their child/ren vaccinated against influenza. Children had lower odds of vaccination if parents did not support (aOR 0.09; 95% CI: 0.01-0.82) or were ambivalent (aOR 0.09; 95% CI: 0.01-0.56) in their support for influenza vaccination. Finally, lack of history of influenza vaccination of child (aOR 0.38; 95% CI: 0.18-0.81) and respondent (aOR 0.25; 95% CI: 0.11-0.56) were associated with lack of receipt of influenza vaccine before admission for acute respiratory infection. CONCLUSIONS: Assisting parents in remembering and accessing influenza vaccination and encouraging health-care providers to recommend vaccination may increase uptake.

Paediatric Active Enhanced Disease Surveillance (PAEDS) 2017 and 2018: Prospective hospital-based surveillance for serious paediatric conditions.

Introduction: The Paediatric Active Enhanced Disease Surveillance (PAEDS) network is a hospital-based active surveillance system employing prospective case ascertainment for selected serious childhood conditions, particularly vaccine-preventable diseases and potential adverse events following immunisation (AEFI). This report presents surveillance data for 2017 and 2018. Methods: Specialist nurses screened hospital admissions, emergency department (ED) records, laboratory and other data on a daily basis in seven paediatric tertiary referral hospitals across Australia to identify children with the conditions under surveillance. In 2017 and 2018 these included acute flaccid paralysis (AFP; a syndrome associated with poliovirus infection), acute childhood encephalitis (ACE), influenza, intussusception (IS; a potential AEFI with rotavirus vaccines), pertussis, varicella-zoster virus infection (varicella and herpes zoster), invasive meningococcal, and invasive Group A streptococcus diseases. An additional social research component was added to evaluate parental attitudes to vaccination. Results: PAEDS captured 1,580 and 925 cases for 2017 and 2018, respectively, across all conditions under surveillance. Key outcomes of PAEDS included: contribution to national AFP surveillance to reach the World Health Organization reporting targets; identification of a third human parechovirus outbreak among other infectious diseases linked to ACE; demonstration of variable influenza activity between 2017 and 2018, with vaccine effectiveness (VE) analysis demonstrating that the protection offered through vaccination is season-dependent. All IS cases associated with vaccine receipt were reported to the relevant state health department. Varicella and herpes zoster case numbers remained unchanged, with vaccine uptake found to be suboptimal among eligible children under the NIP. Enhanced pertussis surveillance continues to capture controls for VE estimation. Surveillance for invasive meningococcal disease showed predominance for serotype B at 57% over 2 years among 77 cases where serotyping was available, and surveillance for invasive group A streptococcus captured severe disease in children. Conclusion: PAEDS continues to provide unique policy-relevant data on serious paediatric conditions using hospital-based sentinel surveillance.

Attitudes about and access to influenza vaccination experienced by parents of children hospitalised for influenza in Australia.

INTRODUCTION: In Australia, influenza hospitalises more children than any other vaccine preventable disease does. Children aged six months or older are recommended to receive annual influenza vaccines, and pregnant women are recommended vaccination to protect infants aged up to six months. However, vaccine uptake is low. This study explored influenza vaccination knowledge and behaviours of parents of children who were hospitalised for influenza, in order to inform strategies that target barriers to uptake. METHODS: We conducted 27 semi-structured interviews with parents/caregivers during or shortly after their child's hospitalisation for laboratory-confirmed influenza in 2017. Questions were guided by the Social Ecological Model exploring all levels of influence on vaccination uptake from the intrapersonal through to policy, via the parents' perspective. Transcripts were inductively analysed. Themes were categorised into the components of the Capability-Opportunity-Motivation-Behaviour (COM-B) model. RESULTS: 20/27 children were aged six months or older; 16/20 had not received an influenza vaccine in 2017. Mothers of 4/7 infants aged less than six months were not vaccinated in pregnancy. The themes regarding barriers to influenza vaccination were: (1) Limited Capability - misinterpretations and knowledge gaps, (2) Lack of Opportunity - inconvenient vaccination pathway, missing recommendations, absence of promotion to all, and the social norm, and (3) Missing Motivation - hierarchy of perceived seriousness, safety concerns, a preference for 'natural' ways. Though most parents, now aware of the severity of influenza, intended to vaccinate their child in future seasons, some harboured reservations about necessity and safety. When parents were asked how to help them vaccinate their children, SMS reminders and information campaigns delivered through social media, schools and childcare were suggested. CONCLUSION: Improving parents' and providers' knowledge and confidence in influenza vaccination safety, efficacy, and benefits should be prioritised. This, together with making influenza vaccination more convenient for parents, would likely raise vaccine coverage.
