Addressing Behavioral Barriers to COVID-19 Testing With Health Literacy-Sensitive eHealth Interventions: Results From 2 National Surveys and 2 Randomized Experiments.

BACKGROUND: Polymerase chain reaction (PCR) testing for COVID-19 was crucial in Australia's prevention strategy in the first 2 years of the pandemic, including required testing for symptoms, contact with cases, travel, and certain professions. However, several months into the pandemic, half of Australians were still not getting tested for respiratory symptoms, and little was known about the drivers of and barriers to COVID-19 PCR testing as a novel behavior at that time. OBJECTIVE: We aimed to identify and address COVID-19 testing barriers, and test the effectiveness of multiple eHealth interventions on knowledge for people with varying health literacy levels. METHODS: The intervention was developed in 4 phases. Phase 1 was a national survey conducted in June 2020 (n=1369), in which testing barriers were coded using the capability-opportunity-motivation-behavior framework. Phase 2 was a national survey conducted in November 2020 (n=2034) to estimate the prevalence of testing barriers and health literacy disparities. Phase 3 was a randomized experiment testing health literacy-sensitive written information for a wide range of barriers between February and March 2021 (n=1314), in which participants chose their top 3 barriers to testing to view a tailored intervention. Phase 4 was a randomized experiment testing 2 audio-visual interventions addressing common testing barriers for people with lower health literacy in November 2021, targeting young adults as a key group endorsing misinformation (n=1527). RESULTS: In phase 1, barriers were identified in all 3 categories: capability (eg, understanding which symptoms to test for), opportunity (eg, not being able to access a PCR test), and motivation (eg, not believing the symptoms are those of COVID-19). Phase 2 identified knowledge gaps for people with lower versus higher health literacy. Phase 3 found no differences between the intervention (health literacy-sensitive text for top 3 barriers) and control groups. Phase 4 showed that a fact-based animation or a TikTok-style video presenting the same facts in a humorous style increased knowledge about COVID-19 testing compared with government information. However, no differences were found for COVID-19 testing intentions. CONCLUSIONS: This study identified a wide range of barriers to a novel testing behavior, PCR testing for COVID-19. These barriers were prevalent even in a health system where COVID-19 testing was free and widely available. We showed that key capability barriers, such as knowledge gaps, can be improved with simple videos targeting people with lower health literacy. Additional behavior change strategies are required to address motivational issues to support testing uptake. Future research will explore health literacy strategies in the current context of self-administered rapid antigen tests. The findings may inform planning for future COVID-19 variant outbreaks and new public health emergencies where novel testing behaviors are required.

Impact of COVID-19 on the capacity to self-manage health and chronic conditions.

Objective: To investigate well-being, lifestyle behaviors, self-management capacity and healthcare utilization among adults with chronic conditions at the outbreak of the COVID-19 pandemic. Methods: Data was collected from two interviewer-administered telephone surveys conducted between March 27 - May 22, 2020. Participants were patients at Chicago-area clinics. Self-report and validated measures were used for study-related outcomes. Results: A total of 553 participants (age range 23-88) completed data collection at both timepoints. One in five (20.7%) participants experienced stress due to the coronavirus most or all the time and rates of negative well-being were high (WHO-5 Index mean = 58.7%). Almost a quarter (22.3%) engaged in hazardous drinking and 79.7% reported insufficient physical activity. Nearly one in four participants (23.7%) avoided seeking medical care due to worry about COVID-19. In multivariable analyses, greater COVID-19 related stress was associated with less physical activity, lower self-efficacy, greater difficulty managing health and medications, and delays in seeking medical care due to the coronavirus. Conclusions: Mental well-being, lifestyle behaviors, self-management capacity, and healthcare utilization were impacted in the months following the COVID outbreak. Innovation: These findings suggest health systems should implement proactive measures for detecting and treating emotional and behavioral COVID-related concerns.

Early COVID-19 Attitudes and Behaviors and Their Associations With Later Infection: A Local Perspective From One U.S. City.

BACKGROUND: At the onset of the pandemic, there was poor public awareness and inaction in response to COVID-19; it is less known whether this translated to subsequent infections. OBJECTIVES: To explore whether adults who perceived COVID-19 as less of a threat and who were not taking early actions were more likely to become infected over the following year. RESEARCH DESIGN: Survey data from the ongoing (COVID-19 & Chronic Conditions (C3) anonymized for review) cohort study. PARTICIPANTS: Six hundred forty-two adults with a mean age of 63 and ≥1 chronic condition. MEASURES: Self-reported attitudes and behaviors regarding COVID-19 were assessed from March 13 to April 3, 2020, and COVID-19 infection status was captured between May 2020 and January 2021. Bivariate and multivariable analyses examined associations between early perceptions and behaviors with later infection. RESULTS: Approximately 7% reported infection with COVID-19 (N = 46). Adults who perceived the threat of COVID-19 less seriously at the initial outbreak were more likely to test positive over the following year [odds ratio (OR): 0.81, CI: 0.70-0.94; P = 0.006]. Those who were less likely to believe their actions would affect whether they would become infected were more likely to test positive (OR: 0.87, CI: 0.77-0.99; P = 0.03), as were adults who reported not changing their routines (OR: 0.45; CI: 0.24-0.85; P = 0.01). CONCLUSIONS: Adults with delayed responses in acknowledging the threat of COVID-19 and in changing behaviors were more likely to contract the virus. This investigation provides insight into the consequences of inadequate public understanding and response to COVID-19, and it highlights the importance of promoting early awareness among high-risk groups during public health crises.

COVID-19 messages targeting young people on social media: content analysis of Australian health authority posts.

Health authorities utilized social media during the COVID-19 pandemic to disseminate critical and timely health messages, specifically targeting priority groups such as young people. To understand how social media was used for this purpose, we investigated the content of COVID-19-related social media posts targeting young people (16-29 years old) shared by Australian health departments. Posts targeting young people with COVID-19 information were extracted from all eight Australian State and Territory health department Facebook, Instagram and TikTok accounts over 1 month of the Delta outbreak (September 2021) and analysed thematically. In total, 238 posts targeting young people were identified from 1059 COVID-19 posts extracted. All eight health departments used Facebook, five used Instagram and only one used TikTok. The majority of posts implicitly targeted young people; only 14.7% explicitly mentioned age or 'young people'. All posts included accompanying visuals; 77% were still images like photos or illustrations whilst 23% were moving images like videos and GIFs. Communication techniques included calls to action (63% of posts), responsive communication (32% of posts) and positive emotional appeal (31% of posts). Social marketing techniques catering to young people were used to varying extents despite receiving higher levels of engagement; 45% featured emojis whilst only 16% used humour, 14% featured celebrities and 6% were memes. Priority groups like ethnic/cultural groups and chronic health/disability communities were rarely targeted in this communication. The findings indicate a lack of health communication on social media directed towards young people, highlighting an opportunity for increased use of platforms like TikTok and trends popular with young people online.

COVID-19 information sources in culturally diverse communities in Australia: Cross-sectional survey: Presenter(s): Julie Ayre, The University of Sydney, Australia

Culturally and linguistically diverse communities are a priority group that has been disproportionately affected by the pandemic. However, they have been largely excluded from Australian surveys that capture data about people's knowledge, attitudes, and experiences relating to COVID-19. This study sought to investigate preferred COVID-19 communication channels and information-seeking experiences within these communities. The cross-sectional survey was co-designed with Multicultural Health and bilingual staff, and translated into 11 languages. Participants were recruited in Sydney, Australia, from March 21 to July 9, 2021, with supporting bilingual staff. Linear regression models identified factors associated with difficulty finding easy-to-understand COVID-19 information. Across 708 participants (88% born overseas, 31% poor English proficiency), difficulty finding easy-to-understand COVID-19 information was rated 4.13 for English materials (95%CI: 3.85 to 4.41) and 4.36 for translated materials (95%CI: 4.07 to 4.66) (1 easy to 10 hard). Participants who were older (p<0.001), had low health literacy (Mean Difference (MD)=-1.43, 95%CI -2.03 to -0.82, p<0.001), or poor English proficiency (MD=-1.9, 95%CI-2.51 to -1.29, p<0.001) found it harder to find easy-to-understand English-language COVID-19 information. Those who had greater difficulty finding easy-to-understand translated COVID-19 information were younger (p=0.004), had poor English proficiency (MD=-1.61, 95%CI -2.29 to -0.9, p<0.001), university education (MD=0.77, 95%CI 0.00 to 1.53, p=0.05), and had spent longer living in Australia (p=0.001). They were more likely to rely on friends and family for COVID-19 information (p=0.02). There was significant variation in information-seeking experiences across language groups (p's<0.001). Easy-to-understand and accessible COVID-19 information is urgently needed and must meet the needs of people in culturally and linguistically diverse communities. The findings are highly applicable to other public health issues, highlighting the limitations of a one-size-fits-all approach to public health communication. Health services must work alongside these communities to tailor public health messages and leverage existing communication channels.

Considering potential benefits, as well as harms, from the COVID-19 disruption to cancer screening and other healthcare services.

Since 2020, hundreds of thousands of more deaths than expected have been observed across the globe. Amid the coronavirus 2019 (COVID-19) pandemic, current research priorities are to control the spread of infection and minimise loss of life. However, there may be future opportunities to learn from the pandemic to build a better healthcare system that delivers maximum health benefits with minimum harm. So far, much research has focused on foregone benefits of healthcare services such as cancer screening during the pandemic. A more balanced approach is to recognise that all healthcare services have potential harms as well as benefits. In this way, we may be able to use pandemic 'natural experiments' to identify cases where a reduction in a healthcare service has not been harmful to the population and some instances where this may have even been beneficial.

COVID-19 Testing and Vaccine Willingness: Cross-Sectional Survey in a Culturally Diverse Community in Sydney, Australia.

Objective: The current study examined patterns in COVID-19 testing and vaccination intentions across multiple language groups in Greater Western Sydney, Australia. Methods: Participants completed a cross-sectional survey available from March 21 to July 9, 2021 in Sydney, Australia. Surveys were available in English or translated (11 languages). Participants could complete surveys independently or with support from bilingual staff. Logistic regression models using poststratification weighted frequencies identified factors associated with testing and vaccination intentions. Results: Most of the 708 participants (88%, n=622) were not born in Australia; 31% reported that they did not speak English well or at all (n=220); 70% had no tertiary qualifications (n=497); and 41% had inadequate health literacy (n=290). Half (53.0%) reported willingness to get a COVID-19 vaccine if recommended to them (n=375); 18% were unwilling (n=127), and the remainder unsure (29%, n=205). These proportions varied significantly by language group (p<0.001). Participants were more likely to be unwilling/hesitant if they were female (p=0.02) or did not use Australian commercial information sources (p=0.01). Concerns about side effects (30.4%, n=102) and safety (23.9%, n=80), were key reported barriers to vaccination. Most participants reported high testing intention (77.2%, n=546), with differences observed across language groups (p<0.001). The most frequently reported barrier to testing was concerns about infection at the clinic (26.1%) followed by concerns that testing was painful (25.3%). Conclusion: Different language groups have unique and specific needs to support uptake of COVID-19 testing and vaccination. Health services must work collaboratively with culturally and linguistically diverse communities to provide tailored support to encourage COVID-19 testing and vaccination.

Collateral positives of COVID-19 for culturally and linguistically diverse communities in Western Sydney, Australia.

BACKGROUND: To investigate whether culturally and linguistically diverse (CALD) communities in Western Sydney have experienced any positive effects during the COVID-19 pandemic, and if so, what these were. METHODS: A cross-sectional survey with ten language groups was conducted from 21st March to 9th July 2021 in Sydney, Australia. Participants were recruited through bilingual multicultural health staff and health care interpreter service staff and answered a question, 'In your life, have you experienced any positive effects from the COVID-19 pandemic?' Differences were explored by demographic variables. Free-text responses were thematically coded using the Content Analysis method. RESULTS: 707 people completed the survey, aged 18 to >70, 49% males and 51% females. Only 161 (23%) of those surveyed reported any positive impacts. There were significant differences in the proportion of those who reported positives based on age (p = 0.004), gender (p = 0.013), language (p = 0.003), health literacy (p = 0.014), English language proficiency (p = 0.003), education (p = <0.001) and whether participants had children less than 18 years at home (p = 0.001). Content Analysis of open-ended responses showed that, of those that did report positives, the top themes were 'Family time' (44%), 'Improved self-care' (31%) and, 'Greater connection with others' (17%). DISCUSSION: Few surveyed participants reported finding any positives stemming from the COVID-19 pandemic. This finding is in stark contrast to related research in Australia with participants whose native language is English in which many more people experienced positives. The needs of people from CALD backgrounds must inform future responses to community crises to facilitate an equitable effect of any collateral positives that may arise.

Testing behaviour may bias observational studies of vaccine effectiveness.

BACKGROUND: Recent observational studies suggest that vaccines may have little effect in preventing infection with the Omicron variant of severe acute respiratory syndrome coronavirus 2. However, the observed effects may be confounded by patient factors, preventive behaviours, or differences in testing behaviour. To assess potential confounding, we examined differences in testing behaviour between unvaccinated and vaccinated populations. METHODS: We recruited 1,526 Australian adults for an online randomized study about coronavirus disease 2019 (COVID-19) testing in late 2021, collecting self-reported vaccination status and three measures of COVID-19 testing behaviour: testing in past month or ever and test intention if they woke with a sore throat. We examined the association between testing intentions and vaccination status in the trial's baseline data. RESULTS: Of the 1,526 participants (mean age 31 y), 22% had a COVID-19 test in the past month and 61% ever; 17% were unvaccinated, 11% were partially vaccinated (one dose), and 71% were fully vaccinated (two or more doses). Fully vaccinated participants were twice as likely as those who were unvaccinated (relative risk [RR] 2.2, 95% CI 1.8 to 2.8, p < 0.001) to report positive COVID testing intentions. Partially vaccinated participants had less positive intentions than fully vaccinated participants (RR 0.68, 95% CI 0.52 to 0.89, p < 0.001) but higher intentions than unvaccinated participants (RR 1.5, 95% CI 1.4 to 1.6, p = 0.002). DISCUSSION: Vaccination predicted greater COVID-19 testing intentions and would substantially bias observed vaccine effectiveness. To account for differential testing behaviours, test-negative designs are currently the preferred option, but their assumptions need more thorough examination.

HISTORIQUE: Selon de récentes études observationnelles, les vaccins peuvent avoir peu d'effet sur la prévention de l'infection par le variant Omicron du coronavirus 2 du syndrome respiratoire aigu sévère. Cependant, les effets observés peuvent être biaisés par des facteurs liés aux patients, des comportements préventifs ou des différences de comportements liés aux tests. Pour évaluer les facteurs confusionnels potentiels, les auteurs ont examiné les différences de comportements liés aux tests entre les populations non vaccinées et vaccinées. MÉTHODOLOGIE: Les auteurs ont recruté 1 526 adultes australiens en vue d'une étude randomisée en ligne sur les tests de la maladie à coronavirus 2019 (COVID-19) à la fin de 2021, afin de colliger l'état vaccinal autodéclaré et trois mesures sur les comportements liés aux tests de la COVID-19 : test au cours du mois précédent ou jamais auparavant et intention de se soumettre à un test en cas de mal de gorge. Ils ont examiné l'association entre les intentions de se soumettre à un test et l'état vaccinal dans les données de référence de l'étude. RÉSULTATS: Sur les 1 526 participants (d'un âge moyen de 31 ans), 22 % avaient subi un test de COVID-19 au cours du mois précédent et 61 % n'en avaient jamais subi; 17 % n'étaient pas vaccinés, 11 % l'étaient partiellement (une dose) et 71 % l'étaient pleinement (au moins deux doses). Les participants pleinement vaccinés étaient deux fois plus susceptibles que ceux qui ne l'étaient pas (risque relatif [RR] 2,2, IC à 95 % 1,8 à 2,8, p < 0,001) de déclarer des intentions de se faire tester contre la COVID-19. Les participants partiellement vaccinés avaient des intentions moins positives que les participants pleinement vaccinés (RR 0,68, IC à 95 % 0,52 à 0,89, p < 0,001), mais plus élevées que ceux qui ne l'étaient pas du tout (RR 1,5, IC à 95 % 1,4 à 1,6, p = 0,002). DISCUSSION: La vaccination était prédictive de plus grandes intentions de subir un test de COVID-19 et établissait un biais important à l'égard de l'efficacité réelle des vaccins. Pour tenir compte des comportements différentiels vis-à-vis des tests, les méthodologies de tests négatifs constituent actuellement la solution privilégiée, mais cette hypothèse doit être approfondie.

Addressing the Health Literacy Needs and Experiences of Culturally and Linguistically Diverse Populations in Australia during COVID-19: A Research Embedded Participatory Approach.

Communicating health information quickly and effectively with diverse populations has been essential during the COVID-19 pandemic. However, health communication practices are often top down and poorly designed to rapidly meet diverse health literacy, cultural and contextual needs of the population. This paper describes a research and practice partnership focused on health literacy, multicultural health, and community engagement to address COVID-19 in Australia. The partnership became influential in the local and state-based response to the COVID-19 Delta outbreak in Western and South Western Sydney, an area of high cultural and socioeconomic diversity. Our approach, bringing together academic researchers and frontline health staff working with multicultural populations using a model of co-design and community engagement and action via the "4 M model," has been successful. It supported the Western Sydney community to achieve some of the highest vaccination rates in the world (>90%). There is an ongoing need to engage respectfully and responsively with communities to address specific challenges that they face and tailor communications and supports accordingly for successful pandemic management. Combining co-designed empirical research with community engagement and action ensures needs are robustly identified and can be appropriately addressed to support an effective public health response.

COVID-19 Vaccine Misperceptions in a Community Sample of Adults Aged 18-49 Years in Australia.

Central to a successful population vaccination program is high uptake of vaccines. However, COVID-19 vaccine uptake may be impeded by beliefs based on misinformation. We sought to understand the prevalence and nature of misbeliefs about COVID-19 vaccines, and identify associated factors, shortly after commencement of Australia's national vaccine rollout. A cross-sectional survey was administered to unvaccinated young adults (n = 2050) in Australia aged 18-49 years (mean age 33 years), 13 July-21 August 2021. This sample was previously under-represented in COVID-19 research but shown to have less willingness to vaccinate. Two thirds of participants agreed with at least one misbelief item. Misperceptions about COVID-19 vaccines were found to be significantly associated with lower health literacy, less knowledge about vaccines, lower perceived personal risk of COVID-19, greater endorsement of conspiracy beliefs, and lower confidence and trust in government and scientific institutions. Misbeliefs were more common in participants with less educational attainment, in younger age groups, and in males, as per previous research. Understanding determinants and barriers to vaccination uptake, such as knowledge and beliefs based on misinformation, can help to shape effective public health communication and inform debunking efforts at this critical time and in the future.

Interventions to improve media coverage of medical research: a codesigned feasibility and acceptability study with Australian journalists.

OBJECTIVES: Although the media can influence public perceptions and utilisation of healthcare, journalists generally receive no routine training in interpreting and reporting on medical research. Given growing evidence about the problems of medical overuse, the need for quality media reporting has become a greater priority. This study aimed to codesign and assess the feasibility of a multicomponent training intervention for journalists in Australia. DESIGN: A small pragmatic feasibility study using a pre- and postdesign. SETTING: 90 min online workshop. PARTICIPANTS: Eight journalists currently working in Australia, recruited through the study's journalist advisor and existing contacts of the researchers. INTERVENTION: The training intervention covered a range of topics, including study designs, conflicts of interest, misleading medical statistics, population screening and overdiagnosis. The intervention also provided tools to help journalists with reporting, including a Tip Sheet and list of expert contacts in health and medicine. Preworkshop and postworkshop questionnaires were administered via Qualtrics. MEASURES: Acceptability and feasibility of the intervention, and journalists' knowledge of overdiagnosis and common issues with health stories. Quantitative results were analysed descriptively using SPSS. Qualitative data were thematically analysed. RESULTS: All participants completed preworkshop and postworkshop questionnaires, and 6 completed the 6-week follow-up (75% retention). Feasibility findings suggest the intervention is acceptable and relevant to journalists, with participants indicating the workshop increased confidence with reporting on medical research. We observed increases in knowledge preworkshop to postworkshop for all knowledge measures on overdiagnosis and common issues with media coverage of medicine. Analysis of free-text responses identified several areas for improvement, such as including more examples to aid understanding of the counterintuitive topic of overdiagnosis and more time for discussion. CONCLUSIONS: Piloting suggested the multicomponent training intervention is acceptable to journalists and provided important feedback and insights to inform a future trial of the intervention's impact on media coverage of medicine.

Psychological, social and financial impacts of COVID-19 on culturally and linguistically diverse communities in Sydney, Australia.

OBJECTIVE: To explore the psychological, social and financial outcomes of COVID-19-and the sociodemographic predictors of those outcomes-among culturally and linguistically diverse communities in Sydney, Australia. DESIGN: Cross-sectional survey informed by the Framework for Culturally Competent Health Research conducted between March and July 2021. SETTING: Participants who primarily speak a language other than English at home were recruited from Greater Western Sydney, New South Wales. PARTICIPANTS: 708 community members (mean age: 45.4 years (range 18-91)). 88% (n=622) were born outside of Australia, 31% (n=220) did not speak English well or at all, and 41% (n=290) had inadequate health literacy. OUTCOME MEASURES: Thirteen items regarding COVID-19-related psychological, social and financial outcomes were adapted from validated scales, previous surveys or co-designed in partnership with Multicultural Health and interpreter service staff. Logistic regression models (using poststratification weighted frequencies) were used to identify sociodemographic predictors of outcomes. Surveys were available in English or translated (11 languages). RESULTS: In this analysis, conducted prior to the 2021 COVID-19 outbreak in Sydney, 25% of the sample reported feeling nervous or stressed most/all of the time and 22% felt lonely or alone most/all of the time. A quarter of participants reported negative impacts on their spousal relationships as a result of COVID-19 and most parents reported that their children were less active (64%), had more screen time (63%) and were finding school harder (45%). Mean financial burden was 2.9/5 (95% CI 2.8 to 2.9). Regression analyses consistently showed more negative outcomes for those with comorbidities and differences across language groups. CONCLUSION: Culturally and linguistically diverse communities experience significant psychological, social and financial impacts of COVID-19. A whole-of-government approach is needed to support rapid co-design of culturally safe support packages in response to COVID-19 and other national health emergencies, tailored appropriately to specific language groups and accounting for pre-existing health disparities.

COVID-19 challenges faced by general practitioners in Australia: a survey study conducted in March 2021.

Limited studies at the beginning of the COVID-19 pandemic found GPs have been negatively affected by increased workload, reduced income and major concerns about staff and patient safety. This study aimed to investigate the challenges of COVID-19 in general practice 1 year since it was declared a pandemic. A national cross-sectional online survey was conducted in March 2021 of a convenience sample of 295 Australian GPs attending an online educational webcast. Twenty-five multipart and free-text questions collected information regarding GPs' main COVID-19-related issues and concerns, including COVID-19 vaccines, useful sources of information, information needs and their perceived role as GPs in COVID-19 management. Descriptive statistics were calculated for all quantitative variables. Content analysis was used to analyse text data from open-ended questions. Of the 596 eligible attendees of the online educational webcast, 295 completed the survey (49.5% response rate). One year since COVID-19 was declared a pandemic, GPs still have concerns regarding patients ignoring prescreening and presenting with flu-like symptoms, the safety of their colleagues and family and catching COVID-19 themselves, as well as concerns about the effect of the pandemic on their patients and patients delaying essential care for non-COVID-19 conditions. More education and resources about vaccines was identified as the top information need, which will assist with what GPs' perceived to be their key roles in managing the COVID-19 pandemic, namely educating the public, correcting misunderstandings and providing the COVID-19 vaccine. These findings highlight gaps in communication and information, particularly regarding COVID-19 vaccines. GPs need high-quality information and resources to support them in undertaking complex risk communication with their patients.

Perceived public health threat a key factor for willingness to get the COVID-19 vaccine in Australia.

BACKGROUND: Vaccination rollout against COVID-19 is underway across multiple countries worldwide. Although the vaccine is free, rollout might still be compromised by hesitancy or concerns about COVID-19 vaccines. METHODS: We conducted two online surveys of Australian adults in April (during national lockdown; convenience cross-sectional sample) and November (very few cases of COVID-19; nationally representative sample) 2020, prior to vaccine rollout. We asked about intentions to have a potential COVID-19 vaccine (If a COVID-19 vaccine becomes available, I will get it) and free-text responses (November only). RESULTS: After adjustment for differences in sample demographics, the estimated proportion agreeing to a COVID-19 vaccine if it became available in April (n = 1146) was 76.3%. In November (n = 1941) this was estimated at 71.5% of the sample; additional analyses identified that the variation was driven by differences in perceived public health threat between April and November. Across both surveys, female gender, being younger, having inadequate health literacy and lower education were associated with reluctance to be vaccinated against COVID-19. Lower perceived susceptibility to COVID-19, belief that data on the efficacy of vaccines is 'largely made up', having lower confidence in government, and lower perception of COVID-19 as a public health threat, were also associated with reluctance to be vaccinated against COVID-19. The top three reasons for agreeing to vaccinate (November only) were to protect myself and others, moral responsibility, and having no reason not to get it. For those who were indifferent or disagreeing to vaccinate, safety concerns were the top reason, followed by indecision and lack of trust in the vaccine respectively. CONCLUSIONS: These findings highlight some factors related to willingness to accept a COVID-19 vaccine prior to one being available in Australia. Now that the vaccine is being offered, this study identifies key issues that can inform public health messaging to address vaccine hesitancy.
