To Trust or not to Trust: An Exploratory Qualitative Study of Personal and Community Perceptions of Vaccines Amongst a Group of Young Community Healthcare Workers in Soweto, South Africa

Factors influencing influenza vaccine uptake among adults in Johannesburg, South Africa: A qualitative study

BACKGROUND

Influenza vaccination coverage in South Africa is less than 3 % among the general adult population. We explored factors associated with influenza vaccine uptake using the World Health Organization's Strategic Advisory Group on Immunization (SAGE) 3C (confidence, complacency, convenience) model of vaccine hesitancy.

METHODS

The present study forms part of the Bambisana project, a mixed-methods pre-test-post-test intervention study conducted from 29 April 2023 to 15 April 2024. Participants ≥18 years were enrolled in six Focus Group Discussions (FGDs), stratified by age (≥18-34 and ≥ 35 years). FGDs were audio-recorded, transcribed verbatim, and coded in Dedoose using framework analysis.

RESULTS

Among the 48 participants, most (66.7 %, n = 30) were aged 18-34 years, 65.9 % (n = 29) had completed high school, and 70.2 % (n = 33) were unemployed. Overall, influenza vaccine uptake was associated with three key factors: low confidence, high complacency, and a lack of convenience. Low confidence in the influenza vaccine was associated with negative experiences with COVID-19 vaccines, fear of side effects, vaccine misconceptions, fear of needles, mistrust of public health institutions, and concerns about vaccine effectiveness. Complacency factors included reliance upon traditional and alternative medicines, lack of knowledge about vaccines, and minimising the seriousness of influenza illness. Convenience factors included perceived costs of the vaccine and a lack of influenza vaccine promotion.

CONCLUSION

Addressing confidence, complacency and convenience factors is important to increase influenza vaccine acceptance and uptake in South Africa.

Factors shaping Covid-19 vaccine acceptability among young people in South Africa and Nigeria: An exploratory qualitative study

Covid-19 vaccine hesitancy among young people can be seen as an acute - but not isolated - phenomenon within an alarming longer-term trend of broader vaccine distrust in Africa. Yet there are still considerable knowledge gaps in relation to the scope and drivers of low vaccine acceptability among young people. Moreover, better frameworks and tools are needed to conceptualise and better understand acceptability in this population group. We applied the recently published Accelerate Framework for Young People's Acceptability to guide qualitative research with young people living in South Africa and Nigeria. We aimed to investigate their overall acceptability of the Covid-19 vaccine, and explore factors shaping this acceptability and willingness to be vaccinated. In collaboration with seven community-based organisation partners, we conducted 12 in-person focus groups and 36 remote interviews with 163 individuals aged 15-24. Through a collaborative, iterative process we conducted thematic analysis, incorporating aspects of both deductive and inductive approaches. Our findings show how vaccine acceptability is shaped by a multiplicity of inter-related factors. They also provide a more in-depth perspective of some of these phenomena, their relative importance and their connections in this group of young people. Limited vaccine understanding, conflicting information and distrust, the influence of others, and fear of side effects were key inter-related drivers of low vaccine acceptability. Factors promoting Covid-19 vaccine acceptability were instead: positive perceptions of vaccine safety and efficacy, protection from disease, protection of others, and a desire to return to normal activity. We discuss implications of these findings for policy and practice, both to increase acceptability of Covid-19 vaccination among young people, and more broadly promote vaccination as a critical component of public health programs. Lastly, we reflect on this first application of theAccelerate Framework, and implications for its use in future studies.

Role of Individual, Social and Health Factors as Determinants of COVID-19 Vaccine Hesitancy: Results from the Second Phase of the Italian EPICOVID19 Web-Based Survey

BACKGROUND

Despite scientific breakthroughs in vaccine development, some people remain reluctant to accept the anti-SARS-CoV-2 vaccine. This study evaluates attitudes and behaviours towards the vaccine and factors associated with refusal/hesitancy at the start of Italy's vaccination campaign.

METHODS

EPICOVID19 is a two-phase observational web-based study where adult volunteers completed questionnaires in April-June 2020 and January-February 2021. Refusal/hesitancy towards the vaccine was assessed among those not yet vaccinated. We analysed factors associated with refusal/hesitancy by applying multivariate multinomial logistic regression models.

RESULTS

Among 36,820 survey participants (mean age of 51 years, 59.7% women, 63.6% highly educated), 2449 (6.7%) were against or hesitant, 4468 (12.1%) were inclined but unsure, and 29,903 (81.2%) were willing to be vaccinated. Factors positively associated with refusal/hesitancy included female sex, middle age, at-risk occupations, medium and low education, deprived status, being underweight, previous SARS-CoV-2 positivity, poor perceived health, no fear of contracting SARS-CoV-2, the fear of contaminated food and natural disasters, and low trust in science, media, government, or institutions. Low hesitancy was associated with student and retired status, overweight and obesity, moderate and high alcohol consumption, no concern about economic and working conditions, and sensitivity to climate change/environmental pollution and epidemics.

CONCLUSIONS

This survey showed that, during the first month of Italy's vaccination campaign, some individuals were reluctant to receive the anti-SARS-CoV-2 vaccine. This study highlights potential target groups for tailored communication and prevention campaigns.

Determinants of COVID-19 and non-COVID-19 vaccine confidence in low- and middle-income countries: A systematic review of qualitative evidence and thematic synthesis

BACKGROUND

The COVID-19 pandemic has shown the immediate risk for global and public health posed by vaccination inequities worldwide. The regions most affected are low- and middle-income countries (LMICs). In addition to systemic challenges, vaccine hesitancy driven by low vaccine confidence has been identified as a threat to vaccine uptake. The aim of this systematic review of qualitative literature is to explore the determinants of COVID-19 and non-COVID-19 vaccine confidence in LMICs.

METHODS

A systematic review was conducted following the PRISMA and ENTREQ guidelines. The electronic databases Cinahl, Embase, Pubmed, Scopus and Web of Science were searched for qualitative studies focusing on the topic of interest in LMICs published between 2013 and 2023. The quality of the studies was assessed using the Joanna Briggs Institute's Checklist for Qualitative Research. A thematic synthesis was conducted. The study was registered on the Open Science Framework platform.

FINDINGS

66 studies were included in the review. Three main determinants of vaccine confidence were identified: (1) General perceptions of the safety and efficacy of vaccines; (2) Information and experience; (3) Trust in healthcare providers, institutions, and systems. General perceptions of vaccine safety and efficacy were similar between COVID-19 and non-COVID-19 vaccines, and doubts regarding vaccine safety were neither new nor exclusive to the COVID-19 vaccine, indicating a persisting challenge. Furthermore, low vaccine confidence was partly determined by broader dynamics of mistrust towards Western countries and institutions, which was reflected for both vaccine groups. While conspiracy theories have been persisting determinants of low confidence, low COVID-19 vaccine confidence was partly determined by what was perceived as a lack of specific information.

CONCLUSION

Persistent challenges to vaccine confidence were identified, rooted in colonial legacies and global health inequities, as well as limited intercultural approaches to building trust with regards to vaccines.

Horror and Solidarity: Collective Health During the COVID-19 Emergency in Guayaquil, Ecuador

In 2020, Ecuador was among the most affected places in the world in the context of the COVID-19 emergency. Serious problems of structural inequality and governance resulted in corpses lying in the streets of Guayaquil-Ecuador's largest city-while local communities resisted in different ways. We interviewed 18 participants who engaged in actions of solidarity during this context, critically analyzed their discourses, and generated relevant themes. There was a structural scheme of (pandemic) brutality that determined embodied experiences of horror, conditioned by a governance of abandonment and its related problems. To confront such horror, solidary community resistance focused on food, physical and mental health, management of corpses, community-led communication, online education, and political participation. We interpret that this was a process of social determination of collective health and discuss important theoretical, methodological, and ethical-political implications.

The Effects of Behaviorally Informed Messages on COVID-19 Vaccination Intentions and Behavior: Evidence from Randomized Survey Experiments in South Africa

With COVID-19 vaccination rates remaining below optimal levels, scalable interventions to shift vaccination intentions are needed. We embedded two randomized experiments in South Africa's COVID-19 Vaccine Survey (CVACS) to investigate the potential to change vaccine intentions and behavior. In Experiment 1, 3510 unvaccinated South African adults were randomly assigned to a no-message control group, a social norm message, or a message highlighting that vaccines were free, available and easy to obtain. The free and easy message significantly increased vaccine intentions but did not increase other outcome measures. The social proof message was associated with an increase in self-reported vaccination status at follow-up (not significant at traditional statistical thresholds). In Experiment 2, 3608 unvaccinated South African adults were randomly assigned to a no-message control group, a message highlighting gaining greater freedoms, or a message highlighting being part of the solution to the pandemic. Neither value proposition message increased vaccination intentions. Light-touch and scalable messages informed by behavioral science and social marketing principles may increase vaccination intentions and uptake, However, more attention should be paid to understanding the behavioral barriers experienced by different population segments, and to tailoring and targeting messaging to those barriers and segments.

Perceptions and attitudes toward COVID-19 vaccination among health professional students in Australia: a qualitative study

Using two qualitative data sources: free-text responses to an open-ended question of an online survey and subsequent interviews and focus groups, we explored perceptions and attitudes toward COVID-19 vaccination among health professional students enrolled in Australian universities during the pandemic with data collected from October 2021 to April 2022. Students provided free-text responses to the open-ended question (n = 313) in the online survey and participated in interviews or focus groups (n = 17). Data analysis revealed three themes, including perceptions of COVID-19 seriousness and the risk of contracting the virus, information dissemination, and attitudes toward the vaccine mandate. The study identified evolving perceptions of COVID-19 seriousness among Australian health professional students and their sentiments toward the vaccine mandate. There is a need to ensure the quality of information dissemination related to the vaccine mandate. This may not only support students' uptake of mandatory vaccination but also provide a means for them to address vaccination with healthcare consumers and patients.

Impact evaluation of a youth led intervention to increase COVID-19 vaccine uptake in Kwazulu-Natal, South Africa

BACKGROUND

COVID-19 vaccination rates in South Africa remain low at 51% of the adult population being fully vaccinated, defined as having two shorts of the COVID-19 vaccine with or without a booster. To improve vaccine uptake, a community-based intervention was tested in a high vaccine hesitancy community in South Africa. Trained community youths used social media, face to face interactions, door to door and neighbourhood outreach activities to deliver the intervention.

METHODS

To assess if the intervention had an impact, data was collected before the intervention and after the intervention in two districts, Wentworth an intervention site and Newlands East a control site. Both districts are in KwaZulu Natal Province, South Africa. The following outcomes, changes on perceptions and knowledge about COVID-19, intention to get vaccinated for those who were not fully vaccinated and vaccination uptake were assessed using difference-in-difference methods applied through Augmented Inverse-Probability Weighting and contrasts of Potential Outcome Means (POM).

RESULTS

One thousand, one hundred and fifty (1 150) participants agreed to take part in the study at baseline, and 916 (80%) were followed up after the 9-week intervention period. Intention to get vaccinated for COVID-19 was higher (difference-in-difference, DID 20%, 95% CI 6% - 35% higher), more people were fully vaccinated (DID 10%, 95% CI 0% - 20%) or partially vaccinated (DID 16%, 95% CI 6% - 26%) in Wentworth the intervention site compared to Newlands East, the control site. There were noticeable increases on the percentage of study participants indicating trust on the Government's COVID 19 programme, from 24% at baseline to 48% after the intervention in the intervention group than in the control group, 26% baseline and 29% at follow-up. There was a 10% (absolute) increase on the percentage of participants' saying they believed health care workers provided reliable information, 58% at baseline and 68% at follow-up in the intervention group, but there was little change in the control group 56% and 57% for baseline and follow-up respectively.

CONCLUSION

The youth-led intervention implemented in Wentworth, a community with a high rate of vaccine hesitancy, was effective in increasing vaccination uptake. Given the low COVID-19 vaccine coverage in South Africa and across the African region, as well as the new emerging variant of concern (XBB 1.5), there is an urgent need to scale up such intervention at the community level to address persistent misinformation and promote vaccine equality.

COVID-19 Vaccine Hesitancy among Unvaccinated Adults: A Cross-Sectional Exploratory Analysis of Vaccination Intentions in Italy Related to Fear of Infection

From the initial COVID-19 outbreak, Italy was the first Western country to be seriously affected by the pandemic. Understanding vaccine hesitancy can help efforts to achieve broad vaccination coverage. The objectives of this research were to determine the extent of vaccine hesitancy in Italy and to understand the characteristics of those segments of the population with some hesitancy. Between January and February 2021, 41,473 subjects answered the second questionnaire delivered in phase II of the web-based EPICOVID19 survey. Among the included adult volunteers living in Italy, 4653 (11.2%) reported having previously received at least one dose of the COVID-19 vaccine. In the sample of 36,820 respondents, all not vaccinated (age 51.1 ± 13.5; 59.7% female; 63.6% high level of education), the comparison between hesitant and inclined participants was accompanied by percentages and odds ratios. A total of 2449 individuals were hesitant (6.7% of the unvaccinated ones). Hesitancy was higher among women (OR = 1.48; 95%CI: 1.36-1.62); it was highest in the 50-59 and 40-49 age groups and among those with a lower educational level. A higher level of education was associated with a lower proportion of hesitancy (5.54%) compared with 9.44% among respondents with a low level of education (OR = 0.56; 95%CI: 0.46-0.68). Hesitancy was most common in subjects who did not report fear of infection (12.4%, OR = 4.0; 95%CI: 3.46-4.61). The results can guide the design of tailored information and communication campaigns through considering objective and subjective characteristics.

The Social Ecological Model: A Framework for Understanding COVID-19 Vaccine Uptake among Healthcare Workers-A Scoping Review

Vaccination plays a crucial role in combating the global COVID-19 pandemic. Immunizing all healthcare workers (HCWs) is essential for increasing vaccine confidence and acceptance within the general population. Understanding the factors that hinder or facilitate vaccine uptake among HCWs is of utmost importance, considering they are among the first to be vaccinated. This review follows Arksey and O'Malley's five-stage methodological framework. We searched PubMed, Web of Science, ProQuest, WorldCat Discovery, and Google Scholar for peer-reviewed articles published from 2020 to 2023. A descriptive analysis and narrative synthesis approach were employed to collect and synthesize data. Using the social-ecological model as a framework, the literature was categorized into themes at the intrapersonal, interpersonal, organizational, community, and policy levels. We reviewed a total of fifty-three published academic articles, with the majority of studies conducted in Ethiopia and Nigeria. The intention for vaccine uptake resulted in an unsatisfactory (52%) overall uptake rate among HCWs. Individual-level determinants associated with vaccine uptake included being male, middle-aged, being a physician, having a higher level of education, and having a chronic illness. This review identified significant barriers at each level, such as safety concerns, perceived scientific uncertainty, vaccine ineffectiveness, lack of trust in stakeholders, and religious beliefs. Additionally, we identified facilitators at each level, with the most common factors promoting intention to uptake being the desire to protect oneself and others and a high perceived susceptibility to contracting COVID-19. This review highlights the existence of significant barriers to vaccine uptake on the African continent. Given that HCWs play a crucial role in guiding the public's vaccination decisions, it is imperative to prioritize education and training efforts about the safety and effectiveness of COVID-19 vaccines.

Qualitative assessment of COVID-19 vaccination acceptance among healthcare workers in Pima County

In the Spring of 2021, the COVID-19 vaccination was authorized for emergency use by the Food and Drug Administration. Healthcare workers (HCWs) are one of the most trusted sources of information for vaccination choices. However, HCWs at this time appeared to continue to have lower rates of COVID-19 vaccination uptake than expected in Arizona. The objective of this study was to examine factors that play a role in the vaccination decision-making process among Arizona HCWs. Between January and April 2021, 18 semi-structured interviews were conducted among physicians, emergency medical technicians and long-term care nurses in Pima County. The informed consent process was completed for each participant. The interview guide was informed by the Increasing Vaccination model to collect information on vaccination decision-making. A codebook was developed using an inductive approach. Coding and analysis was conducted using the software MAXQDA. Participants were primarily male (11/18, 61%) and white (11/18, 61%). Three participants identified as Hispanic. Initial themes that emerged included: mixed opinions concerning the innovations in COVID-19 vaccine development, access-related barriers, issues related to distribution inequities, concerns about misinformation and conspiracy theories, and dialogue concerning the benefits of requiring mandatory vaccination. The results gathered from this study indicate that there continues to be hesitancy among some healthcare professionals in Pima County. These results will be used to help Arizonan Health Departments promote rollout of novel vaccines more effectively through targeting relevant vaccination decision-making factors among HCWs.

COVID-19 Vaccination Hesitancy among Youths in Soweto, South Africa

In combatting COronaVIrus Disease 2019 (COVID-19), immunization is the most prominent strategy. However, vaccination hesitancy-meaning delays in accepting or denying inoculation regardless of availability-has been identified as an essential threat to global health. Attitudes and perceptions play a pivotal role in vaccine acceptability. Meanwhile, uptake in South Africa's rollout has been particularly disappointing among youths. For that reason, we explored attitudes and perceptions of COVID-19 in 380 youths in Soweto and Thembelihle, South Africa, between April and June 2022. A staggering hesitancy rate of 79.2 percent was recorded (301/380). We found negative attitudes and confounded perceptions of COVID-19 to be fueled by medical mistrust and misinformation, with online channels as the main sources of non- and counterfactual claims stemming mostly from unregulated social media popular with youths. Understanding its underpinnings-and enhancing means of curbing vaccine hesitancy-will be paramount in boosting uptake in South Africa's immunization program, particularly among youths.
