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

Barriers to COVID-19 Vaccination and Perceptions Around Vaccination Uptake Strategies Among African Americans Living in the US South: Opportunities for Public Health Program Intervention

BACKGROUND

This study assesses the differences in vaccine hesitancy by vaccination status among African Americans (AAs) living in South Georgia and identifies preferred vaccine uptake strategies by the non-vaccinated AA.

METHODS

Survey data collected as a part of a COVID-19 Health Literacy program from adult (≥ 18 years) participants (n = 2058) in Albany, GA, was used (October 2022 to July 2023). We dichotomized COVID-19 vaccination status as "vaccinated" if reported having received at least one dose of vaccine, and "non-vaccinated" otherwise. Perception of vaccine barriers was assessed using 28 questions, and vaccine uptake strategies using 7 questions. All were assessed on a 5-point Likert scale, transformed to a dichotomous response, i.e., agree (merged strongly agree or agree responses) and disagree (merged strongly disagree, or disagree responses); neutral responses were dropped. Descriptive analysis and chi-square tests were used to identify the most prominent barriers to vaccination and the preferred uptake strategies among the non-vaccinated.

RESULTS

Nearly 1500 participants provided a non-neutral response to vaccine hesitancy questions, where the majority (90.7%) were vaccinated. Medical concerns and myth-related barriers were significantly associated with being vaccinated or non-vaccinated: for example, only 71.3% of non-vaccinated agreed that blood clots from the vaccine are of concern (a myth) compared to 40.5% of vaccinated (p-value < 0.001). Receiving additional information on the COVID-19 vaccine was selected as the most preferred strategy by the nonvaccinated.

CONCLUSION

Medical concerns and myth-related barriers were the most common reasons for vaccine hesitancy, which could potentially be addressed by providing additional information on COVID-19 vaccination.

Leveraging the Arts to Address and Elevate Vaccine Confidence: A Culturally Responsive and Equitable Evaluation of an Arts Intervention for Black Residents in Rural Georgia

Despite pronounced disparities in COVID-19 cases and mortality among communities of color in the United States, and vaccines being a potentially lifesaving prevention measure, vaccination rates are still lower among racial minorities, especially Black people, compared to White people. Reasons such as distrust in the U.S. government and healthcare system underlie vaccine deliberation, which contributes to low vaccine uptake among Black people. The creative and community-based program, "Equitable Vaccines," uses the arts to address vaccine deliberation and boost vaccine confidence among Black people in rural Georgia. Program facilitators implemented vaccine events, bringing together community members to view an artistic asset (e.g., creative short film) and engage participants in candid conversations surrounding COVID-19 and vaccine deliberation. Subsequently, participants were invited to receive a COVID vaccine and complete a brief online post-event survey. Program facilitators also reported their observations and interactions with participants via an Asana post-event report. An analysis of these fieldnotes highlights the community's evolving experiences with COVID-19, the vaccine, and reasons for vaccine deliberation between late 2021 and 2024. Findings revealed that mistrust in U.S. institutions and systems and misinformation was a prominent theme across the entire program duration, but there was also a shift toward motivation for getting vaccinated toward the latter part of the program. We recommend using creative and culturally responsive techniques in designing, implementing, and evaluating public health interventions to address vaccine deliberation and other public health concerns in Black communities across the United States.

Disparities in Vaccination Amongst Socially Vulnerable Patients with Inflammatory Bowel Disease

INTRODUCTION

Social determinants of health (SDOH) have a known impact on disparities in vaccination. Despite an increased risk for infection in patients with inflammatory bowel disease (IBD), SDOH and vaccination in this population have not been studied. Using census tract-level data from the Centers for Disease Control's social vulnerability index (SVI), we aimed to understand the relationship between SDOH and adherence to guideline-recommended vaccinations in patients with IBD.

METHODS

A single-center retrospective cohort of patients with IBD was used to geocode patient addresses to their individual census tract and corresponding SVI and subthemes (Socioeconomic Status, Household Composition, Minority Status, and Housing/Transportation). We used separate multivariable logistic regressions to examine the relationship between SVI and vaccination against influenza, COVID-19, pneumococcal pneumonia, and herpes zoster.

RESULTS

A total of 7,036 patients were included. Rates of vaccination varied across vaccine-types: influenza (57%), COVID-19 (65%), pneumococcal pneumonia (58%), and herpes zoster (11%). High social vulnerability was associated with lower odds of vaccination against influenza (OR 0.47, p < 0.001), COVID-19 (OR 0.54, p < 0.001), pneumonia (OR 0.73, p = 0.012), and herpes zoster (OR 0.39, p < 0.001). Within the SVI subthemes, Socioeconomic Status, Household Composition, and Minority Status were important factors associated with differences in vaccine uptake.

CONCLUSION

Higher social vulnerability was associated with lower rates of vaccination across all vaccine types. Identifying these disparities in vaccination for socially vulnerable patients with IBD is the first step to reducing preventable infections and ensuring all patients receive high quality, equitable care.

COVID-19 vaccine acceptance and its association with knowledge and attitude among patients with chronic diseases in Ethiopia

COVID-19 vaccine acceptance is crucial for patients with chronic diseases, but previous studies in Ethiopia have yielded inconsistent and inconclusive findings. To fill this gap, we conducted a systematic review and meta-analysis following established guidelines. Our search included relevant articles published between 2019 and 2023 from various sources. We assessed study heterogeneity and publication bias, and performed subgroup and sensitivity analyses. Our findings indicate that the COVID-19 vaccine acceptance rate among patients with chronic diseases in Ethiopia was 55.4%. We also found that good knowledge and a favorable attitude toward the vaccine were positively associated with the acceptance rate. Based on these results, we recommend that healthcare professionals, policymakers, and healthcare guide developers should work more to address the relatively low acceptance rate. Improving the knowledge and attitude further about the COVID-19 vaccines is crucial. Future research should include community-based and qualitative studies to enhance our understanding of vaccines acceptance.

Role of new vaccinators/pharmacists in life-course vaccination

BACKGROUND

Vaccines against diseases such as herpes zoster, pneumococcus and influenza are broadly recommended for older adults, but uptake is frequently low.

VACCINATION BOTTLENECK

Part of the reason may be that access to adult vaccination can be problematic, particularly for minorities and other under-served populations. Potential barriers include complex procedures, limited resources in healthcare systems and lack of structured infrastructure.

STRESS-TESTING EXPENDED VACCINATION

The Covid-19 pandemic necessitated rapid expansion of the infrastructure to deliver adult vaccination, and triggered the use of facilities including pharmacies, schools, faith-based organizations, community organizations, shops and hair salons, drive-through centres and mobile vaccination units.

IMPROVED ADULT VACCINATION SYSTEM

Although many such initiatives were temporary, they demonstrated the principle of effective expansion of adult vaccination and education to a range of new providers and settings. Of these, pharmacist involvement in immunization in particular has consistently been shown to be associated with increased immunization rates.

INTEGRATION OF NEW VACCINATORS

This review discusses results from attempts to expand and simplify the adult vaccination process, potentially allowing vaccination to be initiated by the recipient and completed in a single visit. These studies suggest that expanding adult vaccination access to new providers and/or new settings will require development of an integrated plan for preventive healthcare, covering areas such as setting target coverage rates, financial support, and development of immunization information systems accessible to all vaccination providers to maintain accurate immunization records and support interventions such as reminders.

Interventions employed to address vaccine hesitancy among Black populations outside of African and Caribbean countries: a scoping review

BACKGROUND

Black people are disproportionately affected by structural and social determinants of health, resulting in greater risks of exposure to and deaths from COVID-19. Structural and social determinants of health feed vaccine hesitancy and worsen health disparities.

OBJECTIVE

This scoping review explored interventions that have been employed to address vaccine hesitancy among Black population outside of African and Caribbean countries. This review provides several strategies for addressing this deep-rooted public health problem.

METHODS

The scoping review followed the five-step framework outlined by Arksey and O'Malley. It complies with reporting guidelines from the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). Research studies that examined interventions utilized to promote vaccine confidence within Black populations living outside of African and Caribbean countries were reviewed.

FINDINGS

A total of 20 articles met the inclusion criteria for this study: 17 were quantitative studies and three were mixed-method studies. This scoping review highlighted six themes: educational advancement, messaging, multi-component approaches, outreach efforts, enhancing healthcare access, and healthcare provider leadership.

CONCLUSION

The review identified effective interventions for addressing vaccine hesitancy among Black populations outside Africa and the Caribbean, emphasizing education, multidimensional approaches, and healthcare provider recommendations. It calls for more qualitative research and interventions in countries like Canada and the UK to enhance vaccine confidence and reduce mistrust.

The Social Contagion Potential of Pro-Vaccine Messages on Black Twitter

Black Americans in the US not only suffered from disproportionately high hospitalization and death rates throughout the pandemic but also from the consequences of low COVID-19 vaccination rates. This pattern of disparity is linked to distrust of public health systems that originates from a history of medical atrocities committed against Black people. For that reason, mitigation of race-based inequity in COVID-19 impacts might find more success in grassroots information contagion than official public health campaigns. While Black Twitter is well-positioned as a conduit for such information contagion, little is known about message characteristics that would afford it. Here, we tested the impact of four different message frames (personalization, interactive, fear appeal, neutral) on the social contagion potential of bi-modal social media messages promoting COVID-19 vaccinations and finding personalized messages to be the most shareable. Wary of recommending personalization as the blueprint for setting a social contagion health campaign in motion, we probed further to understand the influence of individual-level variables on the communicability of personalized messages. Subsequently, regression models and focus group data were consulted, revealing that thinking styles, vaccine confidence levels, and attitudes toward social media were significant factors of influence on the contagion potential of personalized messages. We discussed the implications of these results for health campaigns.

Impact of the COVID-19 pandemic on health-care use among patients with cancer in England, UK: a comprehensive phase-by-phase time-series analysis across attendance types for 38 cancers

BACKGROUND

The COVID-19 pandemic resulted in the widespread disruption of cancer health provision services across the entirety of the cancer care pathway in the UK, from screening to treatment. The potential long-term health implications, including increased mortality for individuals who missed diagnoses or appointments, are concerning. However, the precise impact of lockdown policies on national cancer health service provision across diagnostic groups is understudied. We aimed to systematically evaluate changes in patterns of attendance for groups of individuals diagnosed with cancer, including the changes in attendance volume and consultation rates, stratified by both time-based exposures and by patient-based exposures and to better understand the impact of such changes on cancer-specific mortality.

METHODS

In this retrospective, cross-sectional, phase-by-phase time-series analysis, by using primary care records linked to hospitals and the death registry from Jan 1, 1998, to June 17, 2021, we conducted descriptive analyses to quantify attendance changes for groups stratified by patient-based exposures (Index of Multiple Deprivation, ethnicity, age, comorbidity count, practice region, diagnosis time, and cancer subtype) across different phases of the COVID-19 pandemic in England, UK. In this study, we defined the phases of the COVID-19 pandemic as: pre-pandemic period (Jan 1, 2018, to March 22, 2020), lockdown 1 (March 23 to June 21, 2020), minimal restrictions (June 22 to Sept 20, 2020), lockdown 2 (Sept 21, 2020, to Jan 3, 2021), lockdown 3 (Jan 4 to March 21, 2021), and lockdown restrictions lifted (March 22 to March 31, 2021). In the analyses we examined changes in both attendance volume and consultation rate. We further compared changes in attendance trends to cancer-specific mortality trends. Finally, we conducted an interrupted time-series analysis with the lockdown on March 23, 2020, as the intervention point using an autoregressive integrated moving average model.

FINDINGS

From 561 611 eligible individuals, 7 964 685 attendances were recorded. During the first lockdown, the median attendance volume decreased (-35·30% [IQR -36·10 to -34·25]) compared with the preceding pre-pandemic period, followed by a median change of 4·38% (2·66 to 5·15) during minimal restrictions. More drastic reductions in attendance volume were seen in the second (-48·71% [-49·54 to -48·26]) and third (-71·62% [-72·23 to -70·97]) lockdowns. These reductions were followed by a 4·48% (3·45 to 7·10) increase in attendance when lockdown restrictions were lifted. The median consultation rate change during the first lockdown was 31·32% (25·10 to 33·60), followed by a median change of -0·25% (-1·38 to 1·68) during minimal restrictions. The median consultation rate decreased in the second (-33·89% [-34·64 to -33·18]) and third (-4·98% [-5·71 to -4·00]) lockdowns, followed by a 416·16% increase (409·77 to 429·77) upon lifting of lockdown restrictions. Notably, across many weeks, a year-over-year decrease in weekly attendances corresponded with a year-over-year increase in cancer-specific mortality. Overall, the pandemic period revealed a statistically significant reduction in attendances for patients with cancer (lockdown 1 -24 070·19 attendances, p<0·0001; minimal restrictions -19 194·89 attendances, p<0·0001; lockdown 2 -31 311·28 attendances, p<0·0001; lockdown 3 -43 843·38 attendances, p<0·0001; and lockdown restrictions lifted -56 260·50 attendances, p<0·0001) compared with before the pandemic.

INTERPRETATION

The UK's COVID-19 pandemic lockdown affected cancer health service access negatively. Many groups of individuals with cancer had declines in attendance volume and consultation rate across the phases of the pandemic. A decrease in attendances might lead to delays in cancer diagnoses, treatment, and follow-up, putting such groups of individuals at higher risk of negative health outcomes, such as cancer-specific mortality. We discuss the factors potentially responsible for explaining changes in service provision trends and provide insight to help inform clinical follow-up for groups of individuals at risk, alongside potential future policy changes in the care of such patients.

What Caused the Narrowing of Black-White COVID-19 Vaccination Disparity in the US? A Test of 5 Hypotheses

Despite differential uptake of COVID-19 vaccination between Black and non-Hispanic White Americans early in the pandemic, the gap narrowed over time. We tested five hypotheses that could explain the reduction in the disparity. Using a national probability panel of over 1800 individuals surveyed from April 2021 to July 2022, we assessed receipt of recommended doses of COVID-19 vaccines along with (a) reported exposure to deaths due to COVID-19, (b) trust in US health authorities, such as the CDC, (c) knowledge about the safety and efficacy of COVID-19 vaccination, (d) media use as a source of information, and (e) access to COVID-19 vaccines. Only increases in knowledge about the safety and efficacy of COVID-19 vaccines uniquely mediated the increase in vaccination uptake among non-Hispanic Black compared to White, Asian and Hispanic panelists. While trust in CDC and exposure to COVID-19 deaths were related to vaccination acceptance at baseline, those factors were not associated with change in reported vaccination coverage. In addition, neither differential access nor media use explained the increase. Enhanced knowledge about the safety and efficacy of COVID-19 vaccination transmitted from within the Black community likely helped to increase vaccination relative to other racial-ethnic groups.

Attitudes, Beliefs, and Perceptions Associated with Mask Wearing within Four Racial and Ethnic Groups Early in the COVID-19 Pandemic

BACKGROUND

While previous studies have identified a range of factors associated with mask wearing in the US, little is known about drivers of mask-wearing among racial and ethnic minority groups. This analysis assessed whether factors positively associated with wearing a mask early in the pandemic differed between participants grouped by race/ethnicity (Hispanic, non-Hispanic Black, non-Hispanic Asian, and non-Hispanic White).

METHOD

Data were obtained from a US internet panel survey of 3217 respondents during May-November 2020 (weighted by race/ethnicity, age, gender, and education to the US national population). Within each of the four available racial/ethnic groups, crude and adjusted odds ratios (COR and AOR) were calculated using logistic regression to assess factors positively associated with wearing a mask. Adjusted models were controlled for age, gender, education, county COVID-19 case count, presence of a state-issued mask mandate, and interview month.

RESULTS

The following variables were most strongly positively associated with mask wearing (p<0.05) in each racial/ethnic group: Hispanic-seeing others wearing masks (AOR: 6.7), importance of wearing a mask combined with social distancing (AOR: 3.0); non-Hispanic Black-belief that wearing a mask would protect others from coronavirus (AOR: 5.1), reporting hearing that one should wear a mask (AOR: 3.6); non-Hispanic Asian-belief that people important to them believe they should wear a mask (COR: 5.1, not statistically significant); and non-Hispanic White-seeing others wearing masks (AOR: 3.1), importance of wearing a mask (AOR: 2.3).

CONCLUSION

Public health efforts to encourage mask wearing should consider the diversity of behavioral influences within different population groups.

COVID-19 among Black people in Canada: a scoping review

INTRODUCTION

The COVID-19 pandemic exacerbated health inequities worldwide. Research conducted in Canada shows that Black populations were disproportionately exposed to COVID-19 and more likely than other ethnoracial groups to be infected and hospitalized. This scoping review sought to map out the nature and extent of current research on COVID-19 among Black people in Canada.

METHODS

Following a five-stage methodological framework for conducting scoping reviews, studies exploring the effects of the COVID-19 pandemic on Black people in Canada, published up to May 2023, were retrieved through a systematic search of seven databases. Of 457 identified records, 124 duplicates and 279 additional records were excluded after title and abstract screening. Of the remaining 54 articles, 39 were excluded after full-text screening; 2 articles were manually picked from the reference lists of the included articles. In total, 17 articles were included in this review.

RESULTS

Our review found higher rates of COVID-19 infections and lower rates of COVID-19 screening and vaccine uptake among Black Canadians due to pre-COVID-19 experiences of institutional and structural racism, health inequities and a mistrust of health care professionals that further impeded access to health care. Misinformation about COVID-19 exacerbated mental health issues among Black Canadians.

CONCLUSIONS

Our findings suggest the need to address social inequities experienced by Black Canadians, particularly those related to unequal access to employment and health care. Collecting race-based data on COVID-19 could inform policy formulation to address racial discrimination in access to health care, quality housing and employment, resolve inequities and improve the health and well-being of Black people in Canada.

Grassroots and Digital Outreach Strategies Raise Awareness of COVID-19 Information and Research in Baltimore City

We aimed to disseminate reliable COVID-19 information to the Black and Latino communities of Baltimore City, Maryland, between July 2020 and December 2022. With community partners, we disseminated evidence-based COVID-19 information via grassroots and digital strategies, including Hopkins Opportunity for Participant Engagement, and connected volunteers to COVID-19 research. Using a multimodal approach facilitated dissemination of reliable information and raised awareness of research; evaluation of trust is ongoing. Robust, multimodal strategies are needed to foster trust and equity among diverse communities. (Am J Public Health. 2024;114(S1):S69-S73. https://doi.org/10.2105/AJPH.2023.307492).

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.

COVID-19 Vaccination: Comparison of Attitudes, Decision-Making Processes, and Communication among Vaccinated and Unvaccinated Black Americans

BACKGROUND

COVID-19 vaccination rates remain suboptimal among Black Americans who disproportionately experience higher hospitalization and death rates than White Americans.

METHODS

We conducted a multi-method (interviews and surveys) study among 30 Black Americans (n = 16 vaccinated, n = 14 unvaccinated) to explore factors related to vaccination hesitancy, decision-making processes, and communication related to uptake. Participants were recruited by using community-driven approaches, including partner collaborations. Thematic analysis was used to analyze qualitative data, and descriptive and bivariate analysis was used for quantitative data.

RESULTS

Of those unvaccinated, 79% (n = 11) stated they were delaying and 21% (n = 3) were declining vaccination indefinitely. When asked about the likelihood of vaccine initiation in 6 months and 12 months, 29% (n = 4) and 36% (n = 5), respectively, stated that they would receive the vaccine. The following themes emerged: (1) COVID-19 vaccination hesitancy exists on a continuum; (2) varied decision-making processes for COVID-19 vaccination; (3) motivators among vaccinated individuals; (4) barriers among unvaccinated individuals; (5) retrieving and navigating vaccine information within the COVID-19 infodemic; and (6) parent perspectives on child vaccination.

CONCLUSIONS

Findings suggest that vaccinated and unvaccinated participants had similar and dissimilar perspectives in decision-making processes and vaccine concerns as shown in the Decision-making Processes for the COVID-19 vaccination (DePC) model. Based on these findings, future studies should further explore how factors influencing decision-making can lead to divergent outcomes for COVID-19 vaccination.
