Examining the influence of community leaders and other community actors on immunisation practices in Australia: A national cross-sectional study.

BACKGROUND: Variation in COVID-19 vaccination coverage and increasing vaccine hesitancy are well documented, especially amongst ethnic minority populations and current channels of vaccine and communication have been found to be inadequate. It has been suggested that more be done to utilise community-led pathways to improve vaccine readiness in ethnic minority communities in Australia. The study aimed to explore receptiveness towards the role of different actors and methods of communication about immunisation. METHODS: A cross-sectional survey of 1,227 adults in Australia was conducted to examine the roles of various actors in promoting vaccine uptake. Chi-square analyses and independent samples t-tests were used to identify significant associations between sociodemographic characteristics, vaccine practices, and vaccine information-seeking behaviours and (1) COVID-19 vaccine uptake (at least one dose) and (2) speaking a language other than English. RESULTS: At the time of the survey, 93% of respondents had received at least one dose of the COVID-19 vaccine. There were significant associations between COVID-19 vaccine uptake and: perceived capacity to locate accurate and timely vaccine information; receiving the COVID-19 vaccination information from a Nurse or Pharmacist; and receiving a vaccine recommendation by a GP. Additionally, respondents who spoke a language other than English reported were significantly more likely to have received information from family, friends, workplaces, local councils, religious centres, community leaders, and religious leaders than those who only spoke English. CONCLUSION: Significant variations in vaccine practices and vaccine information-seeking behaviours were found, especially in those who speak a language other than English. To enhance vaccine uptake and to address vaccine hesitancy in Australia, vaccine promotion strategies and health communication efforts require significant consideration of information accessibility and communication source preferences.

"COVID is a huge jigsaw puzzle that I am trying to make sense of myself": Exploring the perceptions towards the COVID-19 vaccine communication strategy in Australia amongst unvaccinated Australian adults.

The COVID-19 pandemic and the associated introduction of a novel vaccine has provided researchers with the opportunity to investigate how to support vaccine acceptance and reduce hesitancy using novel approaches. This study aimed to understand the perceptions of COVID-19 unvaccinated Australian adults towards the COVID-19 vaccines and the factors influencing their vaccine decision-making. We also explored their attitudes towards vaccine communication strategies and the availability and quality of resources to support decision-making and preferences during future public health emergencies. In-depth interviews were undertaken with 35 members of the Australian community who self-identified as being unvaccinated against COVID-19 from September to December 2021 and did not intend to vaccinate. Key themes that emerged focused on past experiences of vaccination, feelings of being coerced or pushed into vaccination, concerns about transparency around the development processes used for the COVID-19 vaccines, the value of getting vaccinated and issues regarding the mandates being used. Participants acknowledged that they would be open to talking to peers but held some reservations about the process. Requirements for vaccination have now been lifted in many countries. While governments should continue to strive to promote COVID-19 primary and booster vaccines going forward, this research suggests that there will be a small proportion of the community who continue to actively decline the vaccine. Further work is needed to understand the strategies that can support decision-making during pandemics amongst people who remain uncertain about the need for the vaccines or are concerned about vaccine safety. This includes innovatively exploring the role of peer-to-peer communication and the influence it may have on correcting misunderstandings and supporting confidence.

"It's no use saying it in English": A qualitative study exploring community leaders' perceptions of the challenges and opportunities with translating and interpreting COVID-19 related public health messaging to reach ethnic minorities in Australia.

BACKGROUND: The Australian Government implemented a range of public health response strategies and communication approaches to reduce the spread of COVID-19; however, concerns have been raised around a failure to sufficiently consider culturally and linguistically diverse (CaLD) communities in these processes. This research aimed to understand the factors that have impacted COVID-19 communication and engagement efforts during the pandemic from the perspective of key CaLD community and faith-based leaders. A further aim was to understand the processes that could be adopted to support future communication strategies, including promoting pandemic-related vaccines. APPROACH: This study included 29 key informant interviews with community and faith-based leaders in New South Wales, Australia. RESULTS: The overwhelming message from community leaders was a sense of shared responsibility between their organisations and governments in communicating pertinent and accurate COVID-19 related information to CaLD communities. They expressed a sense of duty to keep their community members safe. However, community leaders and others shouldered significant costs related to resources and time that need to be acknowledged by governments in preparing for future disease outbreaks. They felt that governments should consider: 1) improving communication between governments and CaLD organisations; 2) responding to the specific CaLD needs with greater agility; 3) foregrounding social media in their communication strategy; 4) reinvesting in local public health units to know their population; 5) developing a health ambassadors model program; 6) preparing a hybrid model of translators/interpreters to fill the gap; and, 7) reimagining vaccine information campaigns to target CaLD communities better. CONCLUSION: Given the technical details about the COVID-19 virus conveyed in government information campaigns and the media, ensuring the most vulnerable populations, including people from CaLD backgrounds, access clear, concise and timely public health messaging from governments and community organisations requires further attention.

Behavioural and social drivers of COVID-19 vaccination in Vietnam: a scoping review.

BACKGROUND: Understanding of the behavioural and social drivers (BeSD) of vaccination is key to addressing vaccine hesitancy and accessibility issues. Vietnam's national COVID-19 vaccination programme resulted in high uptake of primary doses among adults, but lower booster doses for adults and primary doses for 5-11 years. This scoping review assessed BeSD influencing COVID-19 vaccine uptake in Vietnam to design interventions on reaching the national vaccination targets. METHOD: We conducted a scoping review by searching PubMed, MedRxiv, LitCOVID, COVID-19 LOVE platform, WHO's COVID-19 research database and seven dominant Vietnamese language medical journals published in English or Vietnamese between 28 December 2019 and 28 November 2022. Data were narratively synthesised and summarised according to the four components of the WHO BeSD framework. The drivers were then mapped along the timeline of COVID-19 vaccine deployment and the evolution of the pandemic in Vietnam. RESULTS: We identified 680 records, of which 39 met the inclusion criteria comprising 224 204 participants. Adults' intention to receive COVID-19 vaccines for themselves (23 studies) ranged from 58.0% to 98.1%. Parental intention to vaccinate their under 11-year-old children (six studies) ranged from 32.8% to 79.6%. Key drivers of vaccination uptake were perceived susceptibility and severity of disease, perceived vaccine benefits and safety, healthcare worker recommendation, and positive societal perception. Commonly reported COVID-19 vaccines' information sources (six studies) were social and mainstream media (82%-67%), television (72.7%-51.6%) and healthcare workers (47.5%-17.5%). Key drivers of COVID-19 uptake remained consistent for both adults and children despite changes in community transmission and vaccine deployment. CONCLUSION: Key enablers of vaccine uptake for adults and children included perceived disease severity, perceived vaccine benefits and safety and healthcare worker recommendations. Future studies should assess vaccine communication targeted to these drivers, national policies and political determinants to optimise vaccine uptake.

A qualitative study on COVID-19 pandemic impacts on parental attitudes and intentions for routine adolescent vaccinations: The role of trust.

INTRODUCTION: The COVID-19 pandemic has contributed to declines in routine childhood and adolescent vaccination coverage globally. While the declines in Australia have been less, they are a concern, given steady increases in coverage prior to the pandemic. Given limited evidence on how the experiences of parents during the pandemic affected their attitudes about and intentions towards adolescent vaccinations, with this study we aimed to explore these. METHODS: This was a qualitative study. We invited parents of adolescents eligible for school-based vaccinations in 2021 from metropolitan, regional and rural areas of New South Wales and Victoria (the most affected States) and South Australia (less affected) to half hour-long online semi-structured interviews. We analysed data thematically and applied a conceptual model of trust in vaccination. RESULTS: In July 2022 we interviewed 15 accepting, 4 hesitant and two parents who refused adolescent vaccinations. We identified three themes: 1. Pandemic impacting on professional and personal lives and routine immunisations; 2. Pandemic strengthening preexisting vaccine hesitancy, with perceived lack of clarity in governmental information about vaccination and stigma around non-vaccinating as contributing factors; 3. Pandemic raising awareness of the benefits of COVID-19 and routine vaccinations, with communication campaigns and one's trusted doctor's vaccination recommendations as contributing factors. CONCLUSIONS: For some parents, experiences of poor system readiness and growing distrust towards health and vaccination systems strengthened their pre-existing vaccine hesitancy. We offer recommendations on how trust in the health system and immunisation can be optimised post-pandemic to increase uptake of routine vaccines. These include improving access to vaccination services and clear, timely information about vaccines; supporting immunisation providers in their immunisation consultations; working alongside communities, and building capacity of vaccine champions.

Understanding the factors that influence communication about COVID-19 vaccines with patients: Perspectives of Australian immunisation providers.

Background: COVID-19 immunisation providers have been at the forefront of the pandemic, and their ability to communicate effectively with patients is key to encouraging COVID-19 vaccine acceptance and uptake. This study explored providers' perspectives on the factors influencing communication with patients about COVID-19 vaccines. Methods: We used an explanatory-sequential mixed-methods approach to conduct the study between December 2021 and March 2022. Phase I involved a cross-sectional survey with immunisation providers in New South Wales (n = 341; 189 general practitioners, 118 nurses and 34 pharmacists), followed by Phase II: semi-structured, in-depth qualitative interviews (n = 19; 10 nurses, 9 pharmacists). We generated descriptive results for the survey. We analysed the qualitative data thematically using an inductive approach. Results: Almost half of survey participants reported communicating often with people who were hesitant about COVID-19 vaccines (49 %; 166/341), however, 21 % (71/341) reported inadequate time to address concerns during consultations. Interview participants reported communication challenges, including time constraints, difficulties addressing and eliciting patient concerns, and keeping up to date with changing information. Conversely, interview participants reported that easy access to government information resources, time to learn about COVID-19 vaccines proactively, knowing about and being able to use tailored strategies to support Aboriginal and Torres Strait Islander and CALD patients were helpful when communicating with patients. Conclusions: Immunisation providers play an important role in patient vaccine acceptance and uptake. Our findings indicate that whilst providers were largely confident in their interactions with patients, further communication support would strengthen providers' skills in communicating with patients who have questions and concerns about COVID-19 vaccines.

Speaking COVID-19: supporting COVID-19 communication and engagement efforts with people from culturally and linguistically diverse communities.

BACKGROUND: Since the emergence of COVID-19, issues have been raised regarding the approach used to engage with Culturally and Linguistically Diverse (CaLD) communities during this public health crisis. This study aimed to understand the factors impacting communication and engagement efforts during the COVID-19 pandemic from the perspective of crucial CaLD community stakeholders and opinion leaders. METHODS: Forty-six semi-structured telephone interviews were undertaken with key stakeholders who have an active role (established before the pandemic) in delivering services and other social support to CaLD communities in Australia. RESULTS: Seven key themes emerged: (1) the digital divide and how to connect with people; (2) information voids being filled by international material; (3) Differentiating established with new and emerging communities' needs; (4) speaking COVID-19; (5) ineffectiveness of direct translations of English language resources; (6) coordination is needed to avoid duplication and address gaps and (7) recognising the improvements in governments' approach. CONCLUSION: Alliances must be set up that can be activated in the future to reduce issues around resource development, translation, and dissemination of messages to minimise gaps in the response. Financial assistance must be provided in a timely way to community organisations to support the development and dissemination of culturally appropriate communication materials.

Vaccine coverage in children born to migrant mothers in Australia: A population-based cohort study.

BACKGROUND: Overall, infant immunisation coverage is currently >90% in Australia, but there are pockets of under-immunised children including children from migrant backgrounds. This study aimed to examine whether on-time vaccination coverage of diphtheria-tetanus-pertussis dose 3 (DTP3) for children born in Australia differed by mother's region of birth and if so, what factors were associated with these differences. METHODS: We conducted a population-based cohort study using linked data on perinatal, immunisation and birth records for 2 million children born in Western Australia and New South Wales between 1996 and 2012. We assessed on-time coverage of DTP3 (vaccination from 2 weeks prior to, and up until 30 days after, the due date) in children with mothers born overseas. Logistic regression models were developed to determine factors associated with on-time coverage for each maternal region of birth and all regions combined, adjusting for a range of demographic factors. Adjusted estimates of coverage were calculated for the different regions of birth. RESULTS: On-time DTP3 coverage was 76.2% in children of Australian born mothers, lower in children of mothers from Oceania (66.7%) and North America (68%), and higher in children born to mothers from South-East Asia (79.9%) and Southern Asia (79.3%). While most variables were consistently associated with lower coverage in all regions of birth, higher socioeconomic status and jurisdiction of birth showed varied results. Adjusted estimates of DTP3 coverage increased in children born to mothers from Australia (78.3%), Oceania (70.5%), Northern Africa (81.5%) and the Middle East (79.6%). DTP3 coverage decreased in children born to mothers from Europe and former USSR (74.6%), North-east Asia (75.2%), Southern Asia (76.7%), North America (65.5) and South/Central America and the Caribbean (73.2%). CONCLUSIONS: On-time vaccination rates differed by mother's region of birth. More research is needed to determine the main reasons for these remaining differences to improve vaccine uptake and also help guide policy and practice.

Improving the impact of non-pharmaceutical interventions during COVID-19: examining the factors that influence engagement and the impact on individuals.

BACKGROUND: During an evolving outbreak or pandemic, non-pharmaceutical interventions (NPIs) including physical distancing, isolation, and mask use may flatten the peak in communities. However, these strategies rely on community understanding and motivation to engage to ensure appropriate compliance and impact. To support current activities for COVID-19, the objectives of this narrative review was to identify the key determinants impacting on engagement. METHODS: An integrative narrative literature review focused on NPIs. We aimed to identify published peer-reviewed articles that focused on the general community (excluding healthcare workers), NPIs (including school closure, quarantine, isolation, physical distancing and hygiene behaviours), and factors/characteristics (including social, physical, psychological, capacity, motivation, economic and demographic) that impact on engagement. RESULTS: The results revealed that there are a range of demographic, social and psychological factors underpinning engagement with quarantine, school closures, and personal protective behaviours. Aside from the factors impacting on acceptance and compliance, there are several key community concerns about their use that need to be addressed including the potential for economic consequences. CONCLUSION: It is important that we acknowledge that these strategies will have an impact on an individual and the community. By understanding the barriers, we can identify what strategies need to be adopted to motivate individuals and improve community compliance. Using a behavioural framework to plan interventions based on these key barriers, will also ensure countries implement appropriate and targeted responses.

Evaluating the health literacy demand and cultural appropriateness of online immunisation information available to refugee and migrant communities in Australia.

BACKGROUND: The internet is a source of health information for many consumers. However, little is known about the availability of online resources about immunisation (for children and adults) directed at refugee and migrant populations. The aim of this study was to evaluate the health literacy demand (understandability, actionability & readability) and cultural appropriateness of immunisation resources in Australia for these communities. METHODS: Our study involved two search approaches. Firstly, Google trends was used to identify the most common search terms used in Australia. Search terms used included 'immunisation', 'vaccine' and 'refugee immunisation' amongst others. These search terms were entered into: Google, Bing, Duck Duck Go and Yahoo and the first 5 pages of results for each search were examined. Searches were conducted from November 2018 to June 2019. Secondly, requests were sent out directly to key stakeholders in local health districts and state/territory health departments. Understandability and actionability were assessed using the Patient Education Materials Assessment Tool (PEMAT). The Simple Measure of Gobbledygook (SMOG) and the Flesch readability ease tools were used to assess readability. Cultural appropriateness was assessed using additional criteria developed by the Centre for Culture, Ethnicity and Health (CEH), Victoria, Australia. RESULTS: 27/33 resources were included in the analysis. The overall mean understandability score was 70% (range: 50-100%). The overall mean actionability score of the resources was 47% (range: 0-83%). In terms of readability, the mean score was a 10.5, which was indicative of an eleventh grade reading level. The average Flesch-Kincaid readability score was 47.7. The average score for cultural appropriateness was 79% (range: 29-100%). CONCLUSIONS: Our findings suggest that there are currently not many refugee-specific resources on immunisation. Future work needs to better improve the health literacy demand of online immunisation information. Engaging with members from migrant communities is also recommended so that appropriately tailored resources are co-developed.

Why is influenza vaccine uptake so low among Aboriginal adults?

OBJECTIVES: Determine major barriers to, and facilitators of, influenza vaccination of Aboriginal adults, in order to improve coverage from the current level of 30%. METHODS: i) A focus group with 13 Aboriginal Immunisation Healthcare Workers; and ii) a cross-sectional survey of Aboriginal people aged ≥18 years at the 2017 New South Wales Koori Knockout (29 September-2 October). RESULTS: The focus group nominated poor identification of Aboriginality in general practice. Of 273 survey respondents, a substantial minority (30%) were unaware of their eligibility for free influenza vaccination. More than half (52%) believed the vaccine could cause influenza, 40% reported there were better ways than vaccination for avoiding infection and 30% said they would not have the vaccine if it was offered to them. Regarding health service access, few reported experiencing difficulty (17%), feeling uncomfortable (15%) or being discriminated against (8%), but 53% reported not receiving a reminder from a health professional. CONCLUSIONS: Misconceptions about influenza disease and vaccine among Aboriginal people and inadequate identification of Aboriginality in general practice appear to be the greatest barriers to vaccination, rather than health service access in general. Implications for public health: More active communication to and targeting of Aboriginal adults is required; this is even more urgent following the arrival of COVID-19.

Current knowledge of COVID-19 and infection prevention and control strategies in healthcare settings: A global analysis.

OBJECTIVE: In the current absence of a vaccine for COVID-19, public health responses aim to break the chain of infection by focusing on the mode of transmission. We reviewed the current evidence on the transmission dynamics and on pathogenic and clinical features of COVID-19 to critically identify any gaps in the current infection prevention and control (IPC) guidelines. METHODS: In this study, we reviewed global COVID-19 IPC guidelines by organizations such as the World Health Organization (WHO), the US Centers for Disease Control and Prevention (CDC), and the European Centre for Disease Prevention and Control (ECDC). Guidelines from 2 high-income countries (Australia and United Kingdom) and from 1 middle-income country (China) were also reviewed. We searched publications in English on 'PubMed' and Google Scholar. We extracted information related to COVID-19 transmission dynamics, clinical presentations, and exposures that may facilitate transmission. We then compared these findings with the recommended IPC measures. RESULTS: Nosocomial transmission of SARS-CoV-2 in healthcare settings occurs through droplets, aerosols, and the oral-fecal or fecal-droplet route. However, the IPC guidelines fail to cover all transmission modes, and the recommendations also conflict with each other. Most guidelines recommend surgical masks for healthcare providers during routine care and N95 respirators for aerosol-generating procedures. However, recommendations regarding the type of face mask varied, and the CDC recommends cloth masks when surgical masks are unavailable. CONCLUSION: IPC strategies should consider all the possible routes of transmission and should target all patient care activities involving risk of person-to-person transmission. This review may assist international health agencies in updating their guidelines.

Barriers and facilitators of immunisation in refugees and migrants in Australia: an east-African case study.

BACKGROUND: Immunisation programs available in low and middle-income countries include fewer vaccines in comparison to Australia's National Immunisation Program. As a result, refugees and migrants may have a heightened risk of being inadequately immunised upon arrival to Australia. Several studies have suggested that East African immigrants have low vaccination coverage. As such, the aim of this study was to explore the underlying attitudes, barriers and facilitators to immunisation in east African communities in two states of Australia: New South Wales and Victoria. METHODS: A qualitative study involving 17 semi-structured, in-depth interviews were undertaken with East African refugees and migrants living in two states of Australia: New South Wales and Victoria. These refugees and migrants were from four key East African countries: Kenya, Somalia, Ethiopia and South Sudan. Thematic analysis was undertaken to analyse and interpret the results. RESULTS: Language barriers, low risk perception and a lack of education were the key barriers identified by participants. Facilitators mentioned included the development of resources in participants' languages and the implementation of reminder systems consistently across all GP practices. There was also a unanimous agreement amongst participants that community organisations need to play a greater role in the dissemination of information about immunisation. CONCLUSIONS: Further research needs to be undertaken with regards to how education about immunisation is delivered and disseminated to refugee and migrant communities. Current findings also support the need to improve the health literacy of refugees and migrants by providing culturally and linguistically appropriate resources in participants' respective languages.
