Factors Associated with COVID-19 Vaccine Hesitancy among Visible Minority Groups from a Global Context: A Scoping Review

A Cross-Sectional Analysis of Community Perceptions of Flu and COVID-19 Vaccines at Turtle Creek Primary Care Center

BACKGROUND

Influenza (flu) and COVID-19 vaccination rates are subpar across the US, especially in racial and/or socioeconomic minority groups who are understudied in public health literature.

OBJECTIVE

The objective of this mixed-methods study was to elucidate attitudes of patients at the Turtle Creek Primary Care Center, a clinic that cares for ∼70% non-white patients, towards flu and COVID-19 vaccines, with the goal of establishing vaccine education gaps and increasing vaccine uptake in minority communities.

DESIGN/PATIENTS

This study was conducted as a cross-sectional analysis. Authors completed 123 patient phone surveys of patients cared for at the Turtle Creek clinic inquiring about flu and COVID-19 infection status and vaccination uptake (August 26-October 10, 2021).

APPROACH/KEY RESULTS

We found that rates of vaccination were subpar in the Turtle Creek community, with only 54% having received the COVID-19 vaccine and only 44% receiving the flu vaccine regularly. There was a strong association between COVID-19 and flu vaccine acceptance and a notable correlation between vaccine acceptance and age. When assessing how vaccine acceptance was influenced by trusted sources of information, those who cited trusting "medical professionals" and "word of mouth" had higher odds of COVID-19 vaccine acceptance but those who cited trusting "social media" had decreased odds of acceptance. Finally, we uncovered 14 common factors for either vaccine acceptance or refusal that clustered into four overarching themes of trust, need, safety, and availability.

CONCLUSION

These data highlight the necessity of improved vaccine education and reveal targetable populations and approaches for disseminating vaccine information.

Influenza Vaccine Hesitancy among Cancer Survivors in China: A Multicenter Survey

BACKGROUND

Cancer survivors are at higher risk of developing severe complications from influenza due to their compromised immune systems. Despite their increased vulnerability to influenza and the availability of vaccines, vaccine hesitancy among cancer survivors remains a significant public health concern in China.

METHODS

A multicenter, cross-sectional study was conducted among cancer survivors in China from January to December 2023. A total of 500 participants were recruited from the oncology departments of five tertiary hospitals. A structured, self-administered questionnaire was used to collect data on socio-demographic characteristics, cancer-related information, medical history, lifestyle factors, and influenza vaccine hesitancy. Univariate and multivariate logistic regression analyses were performed to identify factors associated with influenza vaccine hesitancy.

RESULTS

The response rate was 97.0% (485/500). Among all participants, 204 (42.06%) reported vaccine hesitancy. The results of multiple logistic regression showed that the longer the end of anti-cancer treatment, without a history of adverse vaccine reactions, and the level of family support played a protective role in vaccine hesitancy. Current rehabilitation status, frequent colds, not being informed by doctors about vaccination, exercising, lack of community vaccination education programs, and concerns about vaccine safety were risk factors that increase vaccine hesitancy.

CONCLUSIONS

A high proportion of cancer survivors in our study reported influenza vaccine hesitancy. Addressing concerns about vaccine safety, improving access to vaccination services, and enhancing doctor-patient communication are crucial for increasing influenza vaccine uptake in this vulnerable population.

Impact of SARS-CoV-2 Vaccine Rollout on Hispanic and Non-Hispanic Admission and Mortality Trends: An Interrupted Time Series Analysis

BACKGROUND

Challenges with SARS-CoV-2 vaccine prioritization, access, and hesitancy have influenced vaccination uptake.

RESEARCH QUESTION

Was the impact of SARS-CoV-2 vaccine rollout on COVID-19 monthly admission and mortality trends different between Hispanic and non-Hispanic populations?

STUDY DESIGN AND METHODS

We used interrupted time series analysis to conduct an ancillary study of the Viral Infection and Respiratory Illness Universal Study registry supplemented by electronic health record data from five participating Mayo Clinic sites in Florida, Arizona, Minnesota, and Wisconsin. We included hospitalized patients with COVID-19 admitted between April 2020 and December 2021. Our primary outcome was the impact of vaccine rollout on admission trends. Our secondary outcome was the impact of vaccine rollout on mortality trends.

RESULTS

This interrupted time series analysis includes 6,442 patients. Vaccine rollout was associated with improved monthly hospital admission trends among both Hispanic and non-Hispanic patients. Among Hispanic patients, pre-vaccine rollout, monthly admissions increased by 12.9% (95% CI, 8.1%-17.9%). Immediately after vaccine rollout, patient admissions declined by -66.3% (95% CI, -75.6% to -53.9%). Post-vaccine rollout, monthly admissions increased by 3.7% (95% CI, 0.2%-7.3%). Among non-Hispanic patients, pre-vaccine rollout, monthly admissions increased by 35.8% (95% CI, 33.4%-38.1%). Immediately after vaccine rollout, patient admissions declined by -75.2% (95% CI, -77.6% to -72.7%). Post-vaccine rollout, monthly admissions increased by 5.6% (95% CI, 4.5%-6.7%). These pre-vaccine rollout admission trends were significantly different (P < .001). Post-vaccine rollout, the change in admission trend was significantly different (P < .001). The associated beneficial impact from vaccine rollout on monthly hospital admission trends among Hispanic patients was significantly lower. The trend in monthly mortality rate was fourfold greater (worse) among Hispanic patients (8.3%; 95% CI, 3.6%-13.4%) vs non-Hispanic patients (2.2%; 95% CI, 0.6%-3.8%), but this was not shown to be related to vaccine rollout.

INTERPRETATION

SARS-CoV-2 vaccine rollout was associated with improved COVID-19 admission trends among non-Hispanic vs Hispanic patients. Vaccine rollout was not shown to influence mortality trends in either group, which were four times higher among Hispanic patients. Improved vaccine rollout may have reduced disparities in admission trends for Hispanic patients, but other factors influenced their mortality trends.

Sociodemographic factors associated with vaccine hesitancy in the South Asian community in Canada

OBJECTIVE

South Asians represent the largest non-white ethnic group in Canada and were disproportionately impacted by the COVID-19 pandemic. We sought to determine the factors associated with vaccine hesitancy in South Asian Canadians.

METHODS

We conducted a cross-sectional analysis of vaccine hesitancy using data collected at the baseline assessment of a prospective cohort study, COVID CommUNITY South Asian. Participants (18 + years) were recruited from the Greater Toronto and Hamilton Area in Ontario (ON) and the Greater Vancouver Area in British Columbia (BC) between April and November 2021. Demographic characteristics and vaccine attitudes measured by the Vaccine Attitudes Examination (VAX) scale were collected. Each item is scored on a 6-point Likert scale, and higher scores reflect greater hesitancy. A multivariable linear mixed effects model was used to identify sociodemographic factors associated with vaccine hesitancy, adjusting for multiple covariates.

RESULTS

A total of 1496 self-identified South Asians (52% female) were analyzed (mean age = 38.5 years; standard deviation (SD): 15.3). The mean VAX score was 3.2, SD: 0.8 [range: 1.0‒6.0]. Factors associated with vaccine hesitancy included: time since immigration (p = 0.04), previous COVID-19 infection (p < 0.001), marital status (p < 0.001), living in a multigenerational household (p = 0.03), age (p = 0.02), education (p < 0.001), and employment status (p = 0.001).

CONCLUSION

Among South Asians living in ON and BC, time since immigration, prior COVID-19 infection, marital status, living in a multigenerational household, age, education, and employment status were associated with vaccine hesitancy. This information can be used to address vaccine hesitancy in the South Asian population in future COVID-19 waves or pandemics.

[Vaccine hesitancy during the COVID-19 pandemic among young people with an ethnic background in east Oslo – a qualitative study]

Background

Few studies have been conducted on young people's attitudes to the COVID-19 vaccine during the pandemic. We wished to examine how young people with an ethnic minority background decided whether to have the COVID-19 vaccine, based on the concept of vaccine hesitancy. Vaccine hesitancy involves uncertainty with regard to vaccination, irrespective of the decision taken.

Material and method

Fourteen qualitative in-depth interviews with young people aged 16-25 years with an ethnic minority background and from the east side of Oslo were analysed and categorised into main themes. The participants also had links to the Middle East, South Asia and Africa.

Results

Several of the study participants were hesitant to be vaccinated. Their hesitation was linked to the impression that the vaccine had been developed rapidly, false rumours, long travel times to vaccination centres and fear of adverse effects. A number called for better information. Vaccination through the school was described as a facilitating factor. Family and friends were less crucial in their assessment of whether to have the COVID-19 vaccine. The majority had trust in the authorities.

Interpretation

Insufficient knowledge about the vaccine and fear of adverse effects, as well as practical barriers associated with undergoing vaccination, appears to contribute to vaccine scepticism among young people with an ethnic minority background. The authorities and healthcare personnel should provide young people with better vaccine information. Information should be provided by personnel they already trust, such as the school nurse.

The state of COVID-19 vaccine confidence and need in Black individuals in Canada: Understanding the role of sociodemographic factors, health literacy, conspiracy theories, traumatic stressors and racial discrimination

BACKGROUND

Black communities in Canada have been among the most affected by the COVID-19 pandemic, in terms of number of infections and deaths. They are also among those most hesitant about vaccination against COVID-19. However, while a few studies have documented the factors associated with COVID-19 vaccine hesitancy, those related to vaccine confidence remain unknown. To respond to this gap, this study aims to investigate factors associated to vaccine confidence in Black individuals in Canada.

METHODS

A total of 2002 participants (1034 women) aged 14 to 89 years old (Mean age = 29.34, SD = 10.13) completed questionnaires assessing sociodemographic information, COVID-19 vaccine confidence and need, health literacy, conspiracy beliefs, major racial discrimination, and traumatic stressors related to COVID-19.

RESULTS

Results showed an average score of COVID-19 vaccine confidence and need of 33.27 (SD = 7.24), with no significant difference between men (33.48; SD = 7.24) and women (33.08; SD = 7.91), t (1999) = 1.19, p = 0.234. However, there were significant differences according to employment status, migration status, age, inhabited province, spoken language, education, marital status, religion, and income. The linear regression model explained 25.8 % of the variance and showed that health literacy (B = 0.12, p < 0.001) and traumatic stressors related to COVID-19 (B = 0.21, p < .001) predicted COVID-19 vaccine confidence and need positively, while conspiracy beliefs (B = -1.14, p < 0.001) and major racial discrimination (B = -0.20, p = 0.044) predicted it negatively.

CONCLUSIONS

This study showed that building the confidence of Black communities in vaccines requires health education, elimination of racial discrimination in the Canadian society and a focus on certain groups (e.g., young people, those living in Quebec and Ontario). The results also argue in favor of involving community leaders and organizations in the development and implementation of vaccination-related tools, strategies and programs by city, provincial and federal public health agencies.

Access to SARS-CoV-2 vaccination in immigrants in Italy, by geographical area of origin

OBJECTIVE

Immigrants are commonly considered disadvantaged and at high risk of not receiving appropriate care, including vaccination. This study aimed to evaluate the access to SARS-CoV-2 vaccination in immigrants, by geographical area of origin, compared with Italian citizens. We also evaluated sex differences in vaccine's coverage by geographical area of origin.

METHODS

We performed a retrospective observational study in four Italian regions, including all resident subjects aged 5-69 years, and undergoing first dose SARS-CoV-2 vaccination in the period 28th December 2020- 3rd April 2022. We estimated cumulative coverage percentages, by age class and geographical area. To compare first-dose vaccine coverage by geographical area of origin, we estimated, through a Poisson analysis, Vaccine Coverage Ratios (VCR) with 95 % confidence intervals (95 %CI), adjusting for age and sex.

RESULTS

We included 16,294,785 Italian citizens and 2,534,351 immigrants aged 5-69 years and resident in the four regions considered. Regarding the geographical area of origin, 40.7 % of immigrants came from Eastern Europe, 13.5 % from North Africa and 13.1 % from Western Asia. A great variability in the first dose vaccine coverage emerged. We documented substantial heterogeneity in the first-dose vaccine coverage within immigrant's population, expressed with Italy as a reference, ranging from 0,768 (95 %CI: 0,766-0,769) in Eastern Europe countries to 1,013 (95 %CI: 1,009 - 1,018) in Eastern Asia. The chance of being vaccinated was found higher in males compared with females for African countries (VCR 1.07, 95 %CI 1.06-1.08) and Western Asian countries (VCR 1.08, 95 %CI 1.07-1.09).

CONCLUSION

We observed substantial heterogeneity in first-dose SARS-CoV-2 vaccination coverage in immigrants, suggesting a different propensity to vaccines according to the geographical area of origin. These data can help define appropriate and tailored strategies in order to improve vaccine coverage in some specific immigrant groups at the local health district level.

Discovery and development of COVID-19 vaccine from laboratory to clinic

The world has recently experienced one of the biggest and most severe public health disasters with severe acute respiratory syndrome coronavirus (SARS-CoV-2). SARS-CoV-2 is responsible for the coronavirus disease of 2019 (COVID-19) which is one of the most widespread and powerful infections affecting human lungs. Current figures show that the epidemic had reached 216 nations, where it had killed about 6,438,926 individuals and infected 590,405,710. WHO proclaimed the outbreak of the Ebola virus disease (EVD), in 2014 that killed hundreds of people in West Africa. The development of vaccines for SARS-CoV-2 becomes more difficult due to the viral mutation in its non-structural proteins (NSPs) especially NSP2 and NSP3, S protein, and RNA-dependent RNA polymerase (RdRp). Continuous monitoring of SARS-CoV-2, dynamics of the genomic sequence, and spike protein mutations are very important for the successful development of vaccines with good efficacy. Hence, the vaccine development for SARS-CoV-2 faces specific challenges starting from viral mutation. The requirement of long-term immunity development, safety, efficacy, stability, vaccine allocation, distribution, and finally, its cost is discussed in detail. Currently, 169 vaccines are in the clinical development stage, while 198 vaccines are in the preclinical development stage. The majority of these vaccines belong to the Ps-Protein subunit type which has 54, and the minor BacAg-SPV (Bacterial antigen-spore expression vector) type, at least 1 vaccination. The use of computational methods and models for vaccine development has revolutionized the traditional methods of vaccine development. Further, this updated review highlights the upcoming vaccine development strategies in response to the current pandemic and post-pandemic era, in the field of vaccine development.

Geographical and practical challenges in the implementation of digital health passports for cross-border COVID-19 pandemic management: a narrative review and framework for solutions

The rapid global spread of infectious diseases, epitomized by the recent COVID-19 pandemic, has highlighted the critical need for effective cross-border pandemic management strategies. Digital health passports (DHPs), which securely store and facilitate the sharing of critical health information, including vaccination records and test results, have emerged as a promising solution to enable safe travel and access to essential services and economic activities during pandemics. However, the implementation of DHPs faces several significant challenges, both related to geographical disparities and practical considerations, necessitating a comprehensive approach for successful global adoption. In this narrative review article, we identify and elaborate on the critical geographical and practical barriers that hinder global adoption and the effective utilization of DHPs. Geographical barriers are complex, encompassing disparities in vaccine access, regulatory inconsistencies, differences across countries in data security and users' privacy policies, challenges related to interoperability and standardization, and inadequacies in technological infrastructure and limited access to digital technologies. Practical challenges include the possibility of vaccine contraindications and breakthrough infections, uncertainties surrounding natural immunity, and limitations of standard tests in assessing infection risk. To address geographical disparities and enhance the functionality and interoperability of DHPs, we propose a framework that emphasizes international collaboration to achieve equitable access to vaccines and testing resources. Furthermore, we recommend international cooperation to establish unified vaccine regulatory frameworks, adopting globally accepted standards for data privacy and protection, implementing interoperability protocols, and taking steps to bridge the digital divide. Addressing practical challenges requires a meticulous approach to assessing individual risk and augmenting DHP implementation with rigorous health screenings and personal infection prevention measures. Collectively, these initiatives contribute to the development of robust and inclusive cross-border pandemic management strategies, ultimately promoting a safer and more interconnected global community in the face of current and future pandemics.

COVID-19 Vaccine Mandates and Vaccine Hesitancy among Black People in Canada

OBJECTIVES

COVID-19 vaccine mandates increased vaccination rates globally. Implemented as a one-size-fits-all policy, these mandates have unintended harmful consequences for many, including Black Canadians. This article reports findings on the interconnectedness of vaccine mandates and vaccine hesitancy by describing a range of responses to mandatory COVID-19 vaccination policies among Black people in Canada.

METHODS

Using qualitative research methods, semi-structured interviews with 36 Black people living in Canada aged 18 years and over across 6 provinces in Canada were conducted. Participants were selected across intersectional categories including migration status, income, religion, education, sex, and Black ethnicity. Thematic analysis informed the identification of key themes using Foucauldian notions of biopower and governmentality.

RESULTS

Our results show how the power relations present in the ways many Black people actualize vaccine intentions. Two main themes were identified: acceptance of the COVID-19 vaccine in the context of governmentality and resistance to vaccine mandates driven by oppression, mistrust, and religion.

CONCLUSION

COVID-19 vaccine mandates may have reinforced mistrust of the government and decreased confidence in the COVID-19 vaccine. Policy makers need to consider non-discriminatory public health policies and monitor how these policies are implemented over time and across multiple sectors to better understand vaccine hesitancy.

Racial/Ethnic Differences in the Predictive Utility of Psychosocial Determinants of COVID-19 Vaccination Intentions

PURPOSE

To test whether the impact of subjective norms, race/ethnicity-specific descriptive norms, vaccine conspiracy beliefs, and prosocial concern on COVID-19 vaccination intentions differs by race/ethnicity for young adults.

DESIGN

Cross-sectional study.

SETTING

May-August 2021 in Texas.

SUBJECTS

Racially/ethnically diverse unvaccinated college students (N = 314).

MEASURES

COVID-19 vaccination intentions, theory-driven constructs (eg, perceived susceptibility), vaccine conspiracy beliefs, prosocial concern, and social norms.

ANALYSIS

Block-sequential multiple Tobit regression.

RESULTS

Results revealed three significant two-way interactions between race/ethnicity and (1) subjective norms, F (5, 251) = 2.28, P < .05; (2) COVID-19 vaccine conspiracy beliefs, F (5, 251) = 2.88, P < .05; and (3) prosocial concern, F (5, 251) = 2.61, P < .05. There was a positive association between subjective norms and intentions for European and African Americans, a positive association between prosocial concerns and intentions for European and multiracial/multiethnic Americans, and a negative association between conspiracy beliefs and intention for Hispanics. The interaction between race/ethnicity and race/ethnicity-specific descriptive norms was not significant, F (5, 251) = 1.09, P = .37.

CONCLUSION

Although based on a relatively small sample, our findings suggest the importance of culturally tailoring COVID-19 vaccination messages to correct conspiracy beliefs, signaling a positive subjective norm, and enhancing prosocial concerns for specific racial-ethnic groups.

Vaccine perceptions among Black adults with long COVID

OBJECTIVES

Low uptake of COVID vaccines within Black communities is a concern given the stark racial inequities associated with the pandemic. Prior research details COVID vaccine perceptions within the general population and Black communities specifically. However, Black individuals with long COVID may be more or less receptive to future COVID vaccination than their peers without long COVID. The impact of COVID vaccination on long COVID symptoms is still controversial, since some studies suggest that vaccination can improve long COVID symptoms, whereas other studies report no significant change in symptoms or a worsening of symptoms. In this study, we aimed to characterize the factors influencing perceptions of COVID vaccines among Black adults with long COVID to inform future vaccine-related policies and interventions.

DESIGN

We conducted 15 semi-structured, race-concordant interviews over Zoom with adults who reported physical or mental health symptoms that lingered for a month or more after acute COVID infection. We transcribed and anonymized the interviews and implemented inductive, thematic analysis to identify factors influencing COVID vaccine perceptions and the vaccine decision-making process.

RESULTS

We identified five themes that influenced vaccine perceptions: (1) Vaccine safety and efficacy; (2) Social implications of vaccination status; (3) Navigating and interpreting vaccine-related information; (4) Possibility of abuse and exploitation by the government and scientific community; and (5) Long COVID status. Safety concerns were amplified by long COVID status and mistrust in social systems due to mistreatment of the Black community.

CONCLUSIONS

Among the factors influencing COVID vaccine perceptions, participants reported a desire to avoid reinfection and a negative immune response. As COVID reinfection and long COVID become more common, achieving adequate uptake of COVID vaccines and boosters may require approaches that are tailored in partnership with the long COVID patient community.

A Public Health Ethics Framework for Populations with Limited English Proficiency

25.6 Million people in the United States have Limited English Proficiency (LEP), defined as insufficient ability to read, write, or understand English. We will (1) Delineate the merits of approaching language as a social determinant of health, (2) highlight pertinent public health values and guidelines which are most relevant to the plight of populations with LEP and (3) Use the COVID-19 pandemic as an example of how a breakdown in public health ethics values created harm for populations and patients with LEP. We define a framework to tease out public health responsibilities given some populations' limited proficiency in a society's predominant language. The American Public Health Association (APHA) public health ethics core values serve as a framework to interrogate current practices. We use the COVID-19 case to illustrate gaps between health policy and healthcare disparities experienced by populations with LEP.

Reasons for COVID-19 vaccine hesitancy in ethnic minority groups: A systematic review and thematic synthesis of initial attitudes in qualitative research

Despite being disproportionately affected by the COVID-19 pandemic, ethnic and racial minority groups show widespread vaccine hesitancy. Adherence to ongoing booster vaccine campaigns is required to contain future spread of the virus and protect health systems. This review aims to appraise and synthesise qualitative studies published from December 2021 to February 2022 addressing the issue for an in-depth exploration of initial COVID-19 vaccine hesitancy in minorities, including refugee, asylum seeker and migrant populations. A systematic literature search of five databases identified 15 eligible studies. Thematic synthesis identified three main themes of "institutional mistrust", "lack of confidence in vaccine and vaccine development process", and "lack of reliable information or messengers". Two minor themes included "complacency/perceived lack of need" and "structural barriers to vaccine access". "Institutional mistrust" permeated several other themes, demonstrating the need for culturally sensitive approaches. Applying our findings to the World Health Organisation's Three C Model of vaccine hesitancy, the "confidence" dimension appears to represent a disproportionately large barrier to vaccine uptake in ethnic minority groups. Indeed, nuanced adaptations of the model may be necessary to explain vaccine hesitancy in those groups. Further research is required to explore factors facilitating vaccine uptake to monitor changes in hesitancy over time.

Scale Development for COVID-19 Vaccine Hesitancy by Integration of Socio-Demographic and Psychological Factors

Vaccination is the most cost-effective way to maintain population health. However, it can only be effective if widespread acceptance is held. The efficacy of COVID-19 vaccines depends on their favor. When countries start to vaccinate their citizens, there is a certain level of skepticism about the effectiveness of the vaccines. The hesitancy study on vaccines has gained momentum following the pandemic. However, few studies have examined the link between the psychological and sociodemographic factors influencing the fit. This paper proposes integrating the concepts of the information systems success and stimulus-organism-response into a cognitive fit theory framework to explore the integration of psychological and sociodemographic factors in the receivers' reactions (n = 1510). This study analyses the factors that influence the hesitancy of vaccines and the public's refusal in Asia and Europe. Receivers' reactions were assessed to various stimuli and we explored the link between psychological and sociodemographic elements and the concept of fit. Two surveys were conducted following the scale development of Mackenzie. The first was to develop the fit scale, while the second was to validate the fit scale. The results of the second survey were analyzed using structural equation modelling. The results indicate that the scale's fit development is valid and reliable. The quality of the vaccine information, the psychological characteristics of the vaccine system, and vaccine receivers' satisfaction are also beneficial factors for emotional and cognitive fit. Maintaining the vaccines' quality and efficiency can help improve the fit between sociodemographic and psychological characteristics. It can also enhance receivers' satisfaction and encourage continued vaccine administration. This study is regarded as one of the first to examine and develop an emotional and cognitive fit scale for practitioners and researchers.

Reaching late adopters: factors influencing COVID-19 vaccination of Marshallese and Hispanic adults

BACKGROUND

Marshallese and Hispanic communities in the United States have been disproportionately affected by COVID-19. Identifying strategies to reach late vaccine adopters is critical for ongoing and future vaccination efforts. We utilized a community-engaged approach that leveraged an existing community-based participatory research collaborative of an academic healthcare organization and Marshallese and Hispanic faith-based organizations (FBO) to host vaccination events.

METHODS

Bilingual Marshallese and Hispanic study staff conducted informal interviews with 55 participants during the 15-minute post-vaccination observation period and formal semi-structured interviews with Marshallese (n = 5) and Hispanic (n = 4) adults post-event to assess the implementation of community vaccine events at FBOs, with a focus on factors associated with the decision to attend and be vaccinated. Formal interview transcripts were analyzed using thematic template coding categorized with the socio-ecological model (SEM). Informal interview notes were coded via rapid content analysis and used for data triangulation.

RESULTS

Participants discussed similar factors influencing attitudes and behaviors toward receiving the COVID-19 vaccine. Themes included: (1) intrapersonal - myths and misconceptions, (2) interpersonal - protecting family and family decision-making, (3) community - trust of community location of events and influence of FBO members and leaders, (4) institutional - trust in a healthcare organization and bilingual staff, and (5) policy. Participants noted the advantages of vaccination delivery at FBOs, contributing to their decision to attend and get vaccinated.

CONCLUSIONS

The following strategies may improve vaccine-related attitudes and behaviors of Marshallese and Hispanic communities not only for the COVID-19 vaccine but also for other preventive vaccinations: 1) interpersonal-level - develop culturally-focused vaccine campaigns targeting the family units, 2) community-level - host vaccination events at convenient and/or trusted locations, such as FBOs, and engage community and/or FBO formal or lay leaders as vaccine ambassadors or champions, and 3) institutional-level - foster trust and a long-term relationship with the healthcare organization and provide bilingual staff at vaccination events. Future research would be beneficial to investigate the effects of replicating these strategies to support vaccine uptake among Marshallese and Hispanic communities.

Vaccine mistrust among Black individuals in Canada: The major role of health literacy, conspiracy theories, and racial discrimination in the healthcare system

The COVID-19 pandemic disproportionately affected Black communities in Canada in terms of infection and mortality rates compared to the general population. Despite these facts, Black communities are among those with the highest level of COVID-19 vaccine mistrust (COVID-19 VM). We collected novel data to analyze the sociodemographic characteristics and factors associated with COVID-19 VM among Black communities in Canada. A survey was conducted among a representative sample of 2002 Black individuals (51.66% women) aged 14-94 years (M = 29.34; SD = 10.13) across Canada. Vaccine mistrust was assessed as the dependent variable and conspiracy theories, health literacy, major racial discrimination in healthcare settings, and sociodemographic characteristics of participants were assessed as independent variables. Those with a history of COVID-19 infection had higher COVID-19 VM score (M = 11.92, SD = 3.88) compared to those with no history of infection (M = 11.25, SD = 3.83), t (1999) = -3.85, p < 0.001. Participants who reported having experienced major racial discrimination in healthcare settings were more likely to report COVID-19 VM (M = 11.92, SD = 4.03) than those who were not (M = 11.36, SD = 3.77), t (1999) = -3.05, p = 0.002. Results also showed significant differences for age, education level, income, marital status, provinces, language, employment status, and religion. The final hierarchical linear regression showed that conspiracy beliefs (B = 0.69, p < 0.001) were positively associated with COVID-19 VM, while health literacy (B = -0.05, p = 0.002) was negatively associated with it. The mediated moderation model showed that conspiracy theories completely mediated the association between racial discrimination and vaccine mistrust (B = 1.71, p < 0.001). This association was also completely moderated by the interaction between racial discrimination and health literacy (B = 0.42, p = 0.008), indicating that despite having a high level of health literacy, those who experienced major racial discrimination in health services developed vaccine mistrust. This first study on COVID-19 VM exclusively among Black individuals in Canada provides data that can significantly impact the development of tools, trainings, strategies, and programs to make the health systems free of racism and increase their confidence in vaccination for COVID-19 and other infectious diseases.

Barriers to COVID-19 vaccine acceptance to improve messages for vaccine uptake in indigenous populations in the central highlands of Guatemala: a participatory qualitative study

INTRODUCTION

As of July 2022, a little over one-third of Guatemalans were fully vaccinated. While COVID-19 vaccination rates are not officially reported nationally by racial/ethnic groups, non-governmental organisations and reporters have observed that COVID-19 vaccination rates are especially low among high-risk Indigenous populations. We conducted one of the first studies on COVID-19 vaccine acceptance in Indigenous populations in the Central Highlands of Guatemala, which aimed to better understand the barriers to COVID-19 vaccine uptake and how to improve vaccine promotional campaigns.

METHODS

In November 2021, we conducted eight focus group discussions (FGDs) with 42 Indigenous men and women and 16 in-depth interviews (IDIs) with community health workers, nurses and physicians in Chimaltenango and Sololá. Using a participatory design approach, our qualitative analysis used constant comparative methods to understand the inductive and deductive themes from the FGD and IDI transcripts.

RESULTS

We found three major overarching barriers to vaccination within the sampled population: (1) a lack of available easily understandable, linguistically appropriate and culturally sensitive COVID-19 vaccine information; (2) vaccine access and supply issues that prevented people from being vaccinated efficiently and quickly; and (3) widespread misinformation and disinformation that prey on people's fears of the unknown and mistrust of the medical establishment and government.

CONCLUSION

When developing COVID-19 vaccine messages, content should be culturally relevant, appropriate for low-literacy populations and in the languages that people prefer to speak. Promotional materials should be in multiple modalities (print, radio and social media) and also have specific Maya cultural references (dress, food and concepts of disease) to ensure messaging connects with intended targets. This study supports the need for more robust research into best practices for communicating about COVID-19 vaccines to marginalised communities globally and suggests that policy makers should invest in targeted local solutions to increase vaccine uptake.

Attitudes toward COVID-19 Vaccine Uptake: A Qualitative Study of Mostly Immigrant Racial/Ethnic Minority Older Adults

(1) Background: Few qualitative studies address diverse older adults' perceptions of COVID-19 vaccination in the United States, including non-English speakers and immigrant populations. This study aims to understand the attitudes of diverse, primarily immigrant older adults in the U.S. toward the COVID-19 vaccine and its influences on their vaccination decision-making. (2) Methods: The research team conducted semi-structured interviews (N = 100) in 2021 focused on understanding ethnically/racially diverse older adults' perceptions of the COVID-19 vaccine. Interviews were recorded, coded, and analyzed using a thematic analysis approach. (3) Results: Thematic analyses identified three themes. (1) Older adults showed mixed attitudes toward the COVID-19 vaccine associated with information consumed and trust in healthcare systems; (2) health concerns and underlying medical conditions were the most influential factors of vaccine uptake; and (3) systemic barriers and trusted figures impacted vaccination decision-making of older adults. (4) Conclusions: Accessible information in diverse languages tailored to the community's fears is needed to combat vaccine mistrust. Vaccine rollout programs need to tackle the fear of vaccine side effects. Attitudes of religious leaders, family members, and physicians considerably influenced vaccine uptake, suggesting their role as trusted members for vaccine messaging for older, primarily immigrant adults. Systemic barriers, namely lack of transportation and inaccessible vaccination sites, contributed to vaccine deterrence.

Trusted information sources in the early months of the COVID-19 pandemic predict vaccination uptake over one year later

INTRODUCTION

COVID-19 vaccine uptake has been a major barrier to stopping the pandemic in many countries with vaccine access. This longitudinal study examined the capability to predict vaccine uptake from data collected early in the pandemic before vaccines were available.

METHODS

493 US respondents completed online surveys both at baseline (March 2020) and wave 6 (June 2021), while 390 respondents completed baseline and wave 7 (November 2021) surveys. The baseline survey assessed trust in sources of COVID-19 information, social norms, perceived risk of COVID-19, skepticism about the pandemic, prevention behaviors, and conspiracy beliefs. Multivariable logistic models examined factors associated with the receipt of at least one COVID-19 vaccine dose at the two follow-ups.

RESULTS

In the adjusted model of vaccination uptake at wave 6, older age (aOR = 1.02, 95 %CI = 1.00-1.04) and greater income (aOR = 1.69, 95 %CI = 1.04-2.73) was associated with positive vaccination status. High trust in state health departments and mainstream news outlets at baseline were positively associated with vaccination at wave 6, while high trust in the Whitehouse (aOR = 0.42, 95 %CI = 0.24-0.74) and belief that China purposely spread the virus (aOR = 0.66, 95 %CI = 0.46-0.96) at baseline reduced the odds of vaccination. In the adjusted model of vaccination uptake at wave 7, increased age was associated with positive vaccination status, and Black race (compared to white) was associated with negative vaccination status. High trust in the CDC and mainstream news outlets at baseline were both associated with being vaccinated at wave 7, while high trust in the Whitehouse (aOR = 0.24, 95 %CI = 0.11-0.51) and belief that the virus was spread purposefully by China (aOR = 0.60, 95 %CI = 0.39-0.93) were negatively associated with vaccination.

CONCLUSIONS

These findings indicated that vaccine uptake could be predicted over a year earlier. Trust in specific sources of COVID-19 information were strong predictors, suggesting that future pandemic preparedness plans should include forums for news media, public health officials, and diverse political leaders to meet and develop coherent plans to communicate to the public early in a pandemic so that antivaccine attitudes do not flourish and become reinforced.

Facilitators of and barriers to COVID-19 vaccination in Grenada: a qualitative study

Objectives

To identify the factors contributing to coronavirus disease 2019 (COVID-19) vaccine hesitancy in Grenada.

Methods

A phenomenological study was conducted using semi-structured interviews at vaccination and pop-up testing clinics during a spike in COVID-19 cases on the island. Interview questions were developed using the health belief model related to perceived threat of COVID-19, perceived benefits of and barriers to COVID-19 vaccination, and cues to action. Data were analyzed using a deductive approach to identify themes, categories, and subcategories.

Results

Twenty-five interviews were transcribed and coded. In all, 68% of participants were unvaccinated, 12% were partially vaccinated, and 20% were fully vaccinated. Data analysis revealed two main themes: facilitators and barriers. Factors more likely to encourage vaccination (facilitators) included trust in medical advice and vaccine efficacy, social responsibility, and vaccine mandates for travel, employment, and social activities. Factors hindering vaccination (barriers) included: perceived low threat of COVID-19; preference for natural remedies; concerns about contraindications because of underlying health conditions; fear; mistrust of vaccines and related messaging; vaccine accessibility; and the many different information sources.

Conclusions

Overcoming vaccine hesitancy is key to combating the detrimental effects of COVID-19 in Grenada. Public health interventions and policies that address barriers and capitalize on facilitators can increase vaccine uptake.

Acceptance of COVID-19 vaccination in a sample of Middle Eastern and North African (MENA) Houston residents

BACKGROUND

COVID-19 vaccination has averted a significant number of deaths in the United States, but vaccination hesitancy continues to be a problem. Therefore, examining vaccination acceptance and/or hesitancy in local communities is critical.

METHODS

A quantitative survey and a multivariable logistic regression model was utilized to determine predictors of COVID-19 vaccination in Middle Eastern and North African (MENA) origin Houston residents. The outcome of interest was COVID-19 vaccination status (vaccinated versus not vaccinated). Covariates included: demographics, health, and COVID-19 factors. Statistical analyses included SAS version 9.4 at a priori significance level of 0.05.

RESULTS

The overall vaccine acceptance rate was significantly high in this population subset (N = 366), with 77.60% vaccinated, and 22.40% not vaccinated. MENA individuals with some college degrees were less likely to report vaccination than those with a graduate degree [Odds Ratio (OR): 0.18; 95% Confidence Interval (CI): 0.04, 0.77]. Homeowners were more likely to get vaccinated than renters (OR: 2.58; 95%CI: 1.17, 5.68). Individuals practicing Islamic faith were more likely to get vaccinated than other religious affiliations (OR: 3.26; 95%CI: 1.15, 9.19). Individuals with hypertension were less likely to get vaccinated than those without it (OR: 0.34; 95%CI: 0.13, 0.92), and those with anxiety were more likely to get vaccinated than those without anxiety (OR: 4.23; 95%CI: 1.68, 10.64).

CONCLUSIONS

Health status, education level, financial stability, and religious affiliation are some of the determining factors that potentially influence vaccination acceptance/hesitancy among the MENA community.

Prevalence, clinical course and outcomes of COVID-19 in peritoneal dialysis (PD) patients: a single-center experience

INTRODUCTION

There are limited data on the effects of COVID-19 on peritoneal dialysis (PD) patients. This study aimed to describe the impact of COVID-19 on the PD population.

METHODS

A monocentric retrospective observational study was conducted on 146 consecutive PD patients followed from January 2020 to March 2022 at the University Hospital of Modena, Italy.

RESULTS

Twenty-seven (18.4%) PD patients experienced 29 episodes of SARS-CoV-2 infection, corresponding to an incidence rate of 0.16 episodes/patient-year. Median age of COVID-19 patients was 60.4 (interquartile range [IQR] 50.2-66.5) years. In unvaccinated patients (n. 9), COVID-19 was always symptomatic and manifested with fever (100%) and cough (77.7%). COVID-19 caused hospital admission of three (33.3%) patients and two (22.2%) died of septic shock. COVID-19 was symptomatic in 83.3% of vaccinated subjects (n.18) and manifested with fever (61.1%) and cough (55.6%). Hospital admission occurred in 27.8% of the subjects but all were discharged home. Median SARS-CoV-2 shedding was 32 and 26 days in the unvaccinated and vaccinated groups, respectively. At the end of the follow-up, COVID-19 triggered the shift from PD to HD in two subjects without affecting the residual renal function of the remaining patients. Overall, COVID-19 caused an excess death of 22.2%. COVID-19 vaccination refusal accounted for only 1.6% in this cohort of patients.

CONCLUSION

COVID-19 incident rate was 0.16 episodes/patient-year in the PD population. About one-third of the patients were hospitalized for severe infection. Fatal outcome occurred in two (7.4%) unvaccinated patients. A low vaccination refusal rate was observed in this population.

Observed versus expected rates of myocarditis after SARS-CoV-2 vaccination: a population-based cohort study

BACKGROUND

Postmarketing evaluations have linked myocarditis to SARS-CoV-2 mRNA vaccines. We sought to estimate the incidence of myocarditis after mRNA vaccination against SARS-CoV-2, and to compare the incidence with expected rates based on historical background rates in British Columbia.

METHODS

We conducted an observational study using population health administrative data from the BC COVID-19 Cohort from Dec. 15, 2020, to Mar. 10, 2022. The primary exposure was any dose of an mRNA vaccine against SARS-CoV-2. The primary outcome was incidence of hospital admission or emergency department visit for myocarditis or myopericarditis within 7 and 21 days postvaccination, calculated as myocarditis rates per 100 000 mRNA vaccine doses, expected rates of myocarditis cases and observedto-expected ratios. We stratified analyses by age, sex, vaccine type and dose number.

RESULTS

We observed 99 incident cases of myocarditis within 7 days (0.97 cases per 100 000 vaccine doses; observed v. expected ratio 14.81, 95% confidence interval [CI] 10.83-16.55) and 141 cases within 21 days (1.37 cases per 100 000 vaccine doses; observed v. expected ratio 7.03, 95% CI 5.92-8.29) postvaccination. Cases of myocarditis per 100 000 vaccine doses were higher for people aged 12-17 years (2.64, 95% CI 1.54-4.22) and 18-29 years (2.63, 95% CI 1.94-3.50) than for older age groups, for males compared with females (1.64, 95% CI 1.30-2.04 v. 0.35, 95% CI 0.21-0.55), for those receiving a second dose compared with a third dose (1.90, 95% CI 1.50-2.39 v. 0.76, 95% CI 0.45-1.30) and for those who received the mRNA-1273 (Moderna) vaccine compared with the BNT162b2 (Pfizer-BioNTech) vaccine (1.44, 95% CI 1.06-1.91 v. 0.74, 95% CI 0.56-0.98). The highest observed-to-expected ratio was seen after the second dose among males aged 18-29 years who received the mRNA-1273 vaccine (148.32, 95% CI 95.03-220.69).

INTERPRETATION

Although absolute rates of myocarditis were low, vaccine type, age and sex are important factors to consider when strategizing vaccine administration to reduce the risk of postvaccination myocarditis. Our findings support the preferential use of the BNT162b2 vaccine over the mRNA-1273 vaccine for people aged 18-29 years.

Improving COVID-19 Vaccine Uptake among Black Populations: A Systematic Review of Strategies

Given the growing body of evidence on COVID-19 vaccine hesitancy among Black populations, the aim of this systematic review was to identify the interventions and strategies used to improve COVID-19 vaccine confidence and uptake among Black populations globally. To identify relevant studies, we conducted a systematic review of the literature based on a systematic search of 10 electronic databases: MEDLINE, Embase, PsycINFO, CINAHL, Scopus, Cochrane Library, Web of Science, Sociological Abstracts, Dissertations and Theses Global, and SocINDEX. We screened a total of 1728 records and included 14 peer-reviewed interventional studies that were conducted to address COVID-19 vaccine hesitancy among Black populations. A critical appraisal of the included studies was performed using the Newcastle-Ottawa Quality Assessment Scale. The intervention strategies for increasing COVID-19 vaccine uptake were synthesized into three major categories: communication and information-based interventions, mandate-based interventions, and incentive-based interventions. Interventions that incorporated communication, community engagement, and culturally inclusive resources significantly improved vaccine uptake among Black populations, while incentive- and mandate-based interventions had less impact. Overall, this systematic review revealed that consideration of the sociocultural, historical, and political contexts of Black populations is important, but tailored interventions that integrate culture-affirming strategies are more likely to decrease COVID-19 vaccine hesitancy and increase uptake among Black populations.

Vaccine Hesitancy during the Coronavirus Pandemic in South Tyrol, Italy: Linguistic Correlates in a Representative Cross-Sectional Survey

Background: German is a minority language in Italy and is spoken by the majority of the inhabitants of the Autonomous Province of Bolzano, South Tyrol. Linguistic group membership in South Tyrol is an established determinant of health information-seeking behavior. Because the COVID-19 incidence and vaccination coverage in the second year of the pandemic in Italy was the worst in South Tyrol, we investigated whether linguistic group membership is related to COVID-19 vaccine hesitancy. Methods: A cross-sectional survey was conducted on a probability-based sample of 1425 citizens from South Tyrol in March 2021. The questionnaire collected information on socio-demographics, including linguistic group membership, comorbidities, COVID-19-related experiences, conspiracy thinking, well-being, altruism, and likelihood of accepting the national vaccination plan. Multiple logistic regression analyses were performed to identify the significant predictors of vaccine hesitancy. Results: Overall, 15.6 percent of the sample reported vaccine hesitancy, which was significantly higher among German speakers than among other linguistic groups. Increased hesitancy was mostly observed in young age, the absence of chronic disease, rural residence, a worsened economic situation, mistrust in institutions, and conspiracy thinking. In the multiple logistic regression analyses, linguistic group membership was not an independent predictor of vaccine hesitancy. Conclusion: Although German is a minority language in Italy and COVID-19 vaccine hesitancy was higher in the German native language group than in the Italian, linguistic group membership was not an independent predictor of hesitancy in the autonomous province. Known predictors of vaccine hesitancy are distributed unevenly across language groups. Whether language group-specific intervention strategies to promote vaccine hesitancy are useful requires further study.

Community engagement to support COVID-19 vaccine uptake: a living systematic review protocol

INTRODUCTION

Widespread vaccination against COVID-19 is one of the most effective ways to control, and ideally, end the global COVID-19 pandemic. Vaccine hesitancy and vaccine rates vary widely across countries and populations and are influenced by complex sociocultural, political, economic and psychological factors. Community engagement is an integral strategy within immunisation campaigns and has been shown to improve vaccine acceptance. As evidence on community engagement to support COVID-19 vaccine uptake is emerging and constantly changing, research that lessens the knowledge-to-practice gap by providing regular and up-to-date evidence on current best-practice is essential.

METHODS AND ANALYSIS

A living systematic review will be conducted which includes an initial systematic review and bimonthly review updates. Searching and screening for the review and subsequent updates will be done in four streams: a systematic search of six databases, grey literature review, preprint review and citizen sourcing. The screening will be done by a minimum of two reviewers at title/abstract and full-text in Covidence, a systematic review management software. Data will be extracted across predefined fields in an excel spreadsheet that includes information about article characteristics, context and population, community engagement approaches, and outcomes. Synthesis will occur using the convergent integrated approach. We will explore the potential to quantitatively synthesise primary outcomes depending on heterogeneity of the studies.

ETHICS AND DISSEMINATION

The initial review and subsequent bimonthly searches and their results will be disseminated transparently via open-access methods. Quarterly briefs will be shared on the reviews' social media platforms and across other interested networks and repositories. A dedicated web link will be created on the Community Health-Community of Practice site for sharing findings and obtaining feedback. A mailing list will be developed and interested parties can subscribe for updates.

Determinants for COVID-19 vaccine hesitancy in the general population: a systematic review of reviews

Aim

Although multiple COVID-19 vaccines are approved for global use, vaccine hesitancy poses a substantial risk for global health. Therefore, the aim of this umbrella review is to identify those factors that influence COVID-19 vaccination hesitancy in the general population. This is necessary to improve the effectiveness of future vaccination programmes.

Methods

PubMed, Embase, Scopus, PsycInfo, the Cochrane Database of Systematic Reviews, Epistemonikos, and PROSPERO (International Prospective Register of Systematic Reviews) were searched on December 21, 2021. This review included reviews which investigated factors of intention, willingness, or hesitancy with regard to the COVID-19 vaccination in adult populations, with no restrictions on setting. Content-based structure was used to synthesise the extracted data. The findings were presented based on the Strategic Advisory Group of Experts (SAGE) Working Group Model for vaccine hesitancy.

Results

A total of 3,392 studies were identified, of which 31 met the inclusion criteria. The most frequently documented factors associated with COVID-19 vaccine hesitancy included contextual factors, such as sex, age, and social inequalities; individual and group factors, such as trust in the healthcare system, public health authorities, and governments, and history of vaccination; vaccine-specific factors, such as concern for vaccine safety, perceived vaccine barriers, perceived effectiveness of vaccines, and concern about the rapid development of the vaccine; and disease-specific factors, such as fear of being infected with COVID-19, perceived severity of COVID-19, and knowledge of COVID-19.

Conclusion

There are multiple factors associated with COVID-19 vaccine hesitancy. Our findings lay the foundation to further understand COVID-19 vaccination uptake and provide possible targets for intervention programmes. However, there are gaps in research concerning certain populations, including vaccination in people with mental disorders.

A novel SARS-CoV-2 subunit vaccine engineered on an immune-activating platform technology

While there are several SARS-CoV-2 vaccines currently available, additional options must be provided that are safe, effective, and affordable for the entire global population. We have developed a novel immune activating platform technology that will fill this need. This recombinant platform protein is produced in insect cells using baculoviral expression technology similar to what is currently used for several other approved vaccines as well as employed by myriad GMP facilities globally. Thus, infrastructure exists for rapid scale up following initial optimizations. Here we report initial results for a SARS-CoV-2 vaccine (OMN008) based on our platform technology. Unadjuvanted OMN008 vaccination resulted in robust antigenicity and neutralization. Additionally, OMN008 vaccination induced a specific CD8 T-cell response. All of these results taken together indicate OMN008 may be an excellent candidate to fill gaps left by the currently available vaccines. Further testing is necessary to fully optimize production; however, overall cost of production should remain low given the simple formulation of this recombinant platform.

Prevalence and Determinants of COVID-19 Vaccine Hesitancy Among the Ethiopian Population: A Systematic Review

Introduction

Although vaccination is the most effective way to end the COVID-19 pandemic, there are growing concerns that vaccine hesitancy may undermine its effectiveness. In Ethiopia, vaccine hesitancy forms a major challenge to the uptake of COVID-19 vaccines. This systematic review examined the prevalence and determinants of the COVID-19 vaccine hesitancy among the Ethiopian population.

Methods

A systematic search of articles was conducted in PubMed, EBSCO, Google Scholar, and Semantic Scholar. Studies that evaluated the prevalence and determinants of COVID-19 vaccine hesitancy in Ethiopia were included. The identified determinants of COVID-19 vaccine hesitancy were analyzed based on the frequency of occurrence in the included studies.

Results

The overall COVID-19 vaccine hesitancy level in the Ethiopian population ranged from 14.1% to 68.7%. The high COVID-19 vaccine hesitancy rate observed in this study was due to contextual factors, individual factors, and vaccine-specific factors. Young age, female sex, living in rural areas, lack of adequate information, and lower education are the most common contextual determinants of the COVID-19 vaccine hesitancy. Lack of awareness about the COVID-19 vaccine, low risk of COVID-19, poor adherence to COVID-19 prevention strategies, and negative attitude towards the COVID-19 vaccine are the most frequently reported personal factors. Common vaccine-specific determinants of COVID-19 vaccine hesitation are the side effects of the vaccine and doubts about its effectiveness of the vaccine.

Conclusion

Our review showed that COVID-19 vaccine hesitancy remains highly prevalent and varied across regions of Ethiopia, with a wide variety of factors associated with it. Potential interventions on the benefits of vaccination and the adverse effects of vaccine rejection are crucial to enhance COVID-19 vaccine uptake among the Ethiopian population.

Opposing Role of Trust as a Modifier of COVID-19 Vaccine Uptake in an Indigenous Population

Native Hawaiians and other Pacific Islanders (NHPIs) were disproportionately impacted by COVID-19 and remain significantly under-vaccinated against SARS-CoV-2. To understand vaccine hesitancy, we surveyed 1124 adults residing in a region with one of the lowest vaccination rates in Hawaii during our COVID-19 testing program. Probit regression analysis revealed that race/ethnicity was not directly associated with the probability of vaccine uptake. Instead, a higher degree of trust in official sources of COVID-19 information increased the probability of vaccination by 20.68%, whereas a higher trust in unofficial sources decreased the probability of vaccination by 12.49% per unit of trust. These results revealed a dual and opposing role of trust on vaccine uptake. Interestingly, NHPIs were the only racial/ethnic group to exhibit a significant positive association between trust in and consumption of unofficial sources of COVID-19 information, which explained the vaccine hesitancy observed in this indigenous population. These results offer novel insight relevant to COVID-19 mitigation efforts in minority populations.

What are the reasons for refusing a COVID-19 vaccine? A qualitative analysis of social media in Germany

BACKGROUND

Vaccination against COVID-19 has been available in Germany since December 2020. However, about 30% of the population report not wanting to be vaccinated. In order to increase the willingness of the population to get vaccinated, data on the acceptance of vaccination and its influencing factors are necessary. Little is known about why individuals refuse the COVID-19 vaccination. The aim of this study was to investigate the reasons leading to rejecting vaccination, based on posts from three social media sites.

METHODS

The German-language versions of Instagram, Twitter and YouTube were searched regarding negative attitudes towards COVID-19 vaccination. Data was extracted until a saturation effect could be observed. The data included posts created from January 20, 2020 to May 2, 2021. This time frame roughly covers the period from the first reports of the spread of SARS-CoV-2 up to the general availability of vaccines against COVID-19 in Germany. We used an interpretive thematic approach to analyze the data and to inductively generate codes, subcategories and categories.

RESULTS

Based on 333 posts written by 323 contributing users, we identified six main categories of reasons for refusing a COVID-19 vaccination: Low perceived benefit of vaccination, low perceived risk of contracting COVID-19, health concerns, lack of information, systemic mistrust and spiritual or religious reasons. The analysis reveals a lack of information among users and the spread of misinformation with regard to COVID-19 and vaccination. Users feel inadequately informed about vaccination or do not understand the information available. These information gaps may be related to information not being sufficiently sensitive to the needs of the target group. In addition to limited information for the general population, misinformation on the internet can also be an important reason for refusing vaccination.

CONCLUSIONS

The study emphasizes the relevance of providing trustworthy and quality-assured information on COVID-19 and COVID-19 vaccination to all population groups. In addition, vaccinations should be easily accessible in order to promote the population's willingness to be vaccinated.
