Vaccination uptake amongst older adults from minority ethnic backgrounds: A systematic review

The desire of autonomy: A lever for vaccination of the elderly? Results of a qualitative study

The COVID-19 pandemic has highlighted the challenges of vaccination and the infectious risks among the elderlies. However, immunization rates for recommended vaccines in this population are insufficient in France. We aimed in this study to identify the levers and obstacles to vaccination among seniors, and to establish the arguments that could lead to some new vaccination behaviors. A qualitative survey based on 14 semi-structured interviews was conducted with people aged 65 and over, living at home in the Auvergne Rhône-Alpes region (France) from March to May 2022. The interviews were recorded, entirely transcribed, then subjected to a thematic content analysis. The results show that participants are keen to preserve their health by maintaining their physical capacity, taking regular exercise and eating a balanced diet. However, vaccination was not mentioned as a mean of preventing infectious diseases. Infections were not perceived as a cause for concern. Furthermore, the physical and cognitive consequences of infectious diseases, which could result in a loss of autonomy, were not known. These elements could be a good lever to bring hesitant elderly people to reconsider their position toward vaccination. Vaccines were not seen as a strategy to prevent loss of autonomy among elderlies. Since vaccines against influenza, COVID-19, shingles, pneumococcus have proved to be effective in protecting against cardiovascular events, this argument might be the starting point for a prevention campaign for the elderly.

Vaccination Motivators and Deterrents Among Undervaccinated Older Adults in North Dakota

Despite increased risk of morbidity and mortality among older adults due to preventable infectious diseases such as influenza, shingles, pneumonia, and COVID-19, many forego receiving some, if not all, of these vaccinations. This study examines vaccination motivators and deterrents for undervaccinated older adults in North Dakota (ND). Adults aged 65+ in ND were mailed a survey (n = 901) with questions gauging vaccination behaviors and perceptions, with 132 of these indicating not receiving certain vaccinations. Further questions assessed reasons they have not been vaccinated against the following diseases: influenza, shingles, pneumonia, and COVID-19 (e.g., "Concerned about side effects", "Vaccines are dangerous", "I'm healthy and I do not need it") and what would make it more likely to get a vaccine (e.g., "More information", "Doctor recommendation", "Easy access to vaccines"). Reasons for remaining unvaccinated varied by vaccine. For influenza and pneumococcal vaccines, respondents were more likely to indicate they are healthy and do not need the vaccine. For shingles and COVID-19, respondents were more likely to indicate concerns about side effects. Factors reported to motivate increasing the likelihood of getting a vaccine were receiving a doctor recommendation, receiving more information, and having a vaccine provided at no cost. These results contribute to our understanding of vaccination behaviors among older adults and underscore specific issues around which to frame interventions tailored to increase vaccine uptake for this population.

COVID-19 vaccine uptake inequality among older adults: A multidimensional demographic analysis

BACKGROUND

Age, race, ethnicity, and sex are important determinants of coronavirus disease of 2019 (COVID-19) outcomes. Older adults (65 years and older) are at the highest risk of COVID-19 morbidity and mortality. Analyzing their vaccine uptake by subclassifying demographics is rare and can assist vaccination policies. This study investigates COVID-19 dose 1 and 2 vaccine uptakes among them by race, ethnicity, and sex.

METHODS

Immunization registry data were used to calculate temporal changes in older adults' COVID-19 vaccine uptake by race, ethnicity, race-sex, and ethnicity-sex in Kentucky's most populous county, Jefferson County, during the first 6 quarters of the COVID-19 vaccination program.

RESULTS

By May 2022, the county's Asian residents had the highest dose 1 and 2 vaccination rates (97.0% and 80.4%), then White residents (90.0% and 80.2%). Black residents had one of the lowest COVID-19 vaccination rates (87.3% and 77.3%). The rate among Hispanic residents (82.0% and 66.4%) was considerably lower than non-Hispanic residents (90.2% and 80.1%). The rates were consistently lower in males.

CONCLUSIONS

Racial, ethnic, and sex-based COVID-19 vaccine inequalities were largely maintained during the study period. Vaccine rollout practices and promotional programs should aim to boost the uptake of the COVID-19 vaccination among racial minority and male older adults.

Factors Related to, and Effective Interventions for, Vaccination Uptake Among Older Adults in Two Asia-Pacific Countries: A Rapid Review

This rapid review aims to present a comprehensive overview of barriers, facilitators, and effective interventions that promote vaccination uptake by older adults in the Asia-Pacific region. Rapid review methodology was applied, using two databases (PubMed, Embase). Articles were included if studies were conducted in Australia, Singapore, Indonesia, and the Philippines; included human population ≥50 years of age, and was published from 2016 to August 2022. Related articles were not found from Indonesia and Philippines. A total of 23 articles met the inclusion criteria, with 19 reporting on barriers and facilitators, whereas, four articles reported effective interventions to promote vaccination uptake. Among the 19 studies that identified barriers and facilitators to vaccination uptake, the more common factors were social influences (n = 8/19), perceived benefits of vaccine (n = 7/19), and perceived vaccine safety (n = 6/19). Interventions that focused on supporting clinicians were found to be effective in leading them to recommend vaccinations among older adults, such as creating awareness on the low baseline vaccination rates among older adults, provision of structured health assessment, and nurse reminders. More studies are needed to ascertain the barriers and facilitators to uptake, as well as to identify effective interventions influencing vaccine uptake among older adults in the Asia-Pacific region.

Testing the impact of differing behavioural science informed text message content in COVID-19 vaccination invitations on vaccine uptake: A randomised clinical trial

Behavioural science constructs can be incorporated into messaging strategies to enhance the effectiveness of public health campaigns by increasing the occurrence of desired behaviours. This study investigated the impact of behavioural science-informed text message strategies on COVID-19 vaccination rates in 18-39-year-olds in an area of low uptake in London during the first vaccination offer round in the United Kingdom. This three-armed randomised trial recruited unvaccinated residents of an urban Central London suburb being offered their first vaccination between May and June 2021. Participants were randomised to receive the control (current practice) text message or one of two different behavioural science-informed COVID-19 vaccine invitation strategies. Both intervention strategies contained the phrase "your vaccine is ready and waiting for you", aiming to evoke a sense of ownership, with one strategy also including a pre-alert message. The main outcome measures were vaccination rates at 3 and 8 weeks after message delivery. A total of 88,820 residents were randomly assigned to one of the three trial arms. Each arm had a vaccine uptake rate of 27.2 %, 27.4 % and 27.3 % respectively. The mean age of participants was 28.2 years (SD ± 5.7), the mean index of multiple deprivation was 4.3 (SD ± 2.0) and 50.4 % were women. Vaccine uptake varied by demographics, however there was no significant difference between trial arms (p = 0.872). Delivery was successful for 53.6 % of text messages. Our choice of behavioural science informed messaging strategies did not improve vaccination rates above the rate seen for the current practice message. This likely reflects the wide exposure to public health campaigns during the pandemic, as such text messages nudges were unlikely to alter existing informed decision-making processes. Text message delivery was relatively low, indicating a need for accurate mobile phone number records and multi-modal approaches to reach eligible patients for vaccination. The protocol was registered at clinicaltrials.gov (NCT04895683) on 20/05/2021.

Anti-racist interventions to reduce ethnic disparities in healthcare in the UK: an umbrella review and findings from healthcare, education and criminal justice

OBJECTIVES

To assess the evidence for anti-racist interventions which aim to reduce ethnic disparities in healthcare, with a focus on implementation in the UK healthcare system.

DESIGN

Umbrella review.

DATA SOURCES

Embase, Medline, Social Policy and Practice, Social Care Online and Web of Science were searched for publications from the year 2000 up to November 2023.

ELIGIBILITY CRITERIA

Only systematic and scoping reviews of anti-racist interventions reported in English were included. Reviews were excluded if no interventions were reported, no comparator interventions were reported or the study was primarily descriptive.

DATA EXTRACTION AND SYNTHESIS

A narrative synthesis approach was used to integrate and categorise the evidence on anti-racist interventions for healthcare. Quality appraisal (including risk of bias) was assessed using the AMSTAR-2 tool.

RESULTS

A total of 29 reviews are included in the final review. 26 are from the healthcare sector and three are from education and criminal justice. The most promising interventions targeting individuals include group-based health education and providing culturally tailored interventions. On a community level, participation in all aspects of care pathway development that empowers ethnic minority communities may provide an effective approach to reducing ethnic health disparities. Interventions to improve quality of care for conditions with disproportionately worse outcomes in ethnic minority communities show promise. At a policy level, structural interventions including minimum wage policies and integrating non-medical interventions such as housing support in clinical care has some evidence for improving outcomes in ethnic minority communities.

CONCLUSIONS

Many of the included studies were low or critically low quality due to methodological or reporting limitations. For programme delivery, different types of pathway integration, and providing a more person-centred approach with fewer steps for patients to navigate can contribute to reducing disparities. For organisations, there is an overemphasis on individual behaviour change and recommendations should include a shift in focus and resources to policies and practices that seek to dismantle institutional and systemic racism through a multilevel approach.

The impact of comorbidities and sociodemographic predictors on pneumococcal vaccination coverage in adults with coronary heart disease

Aim: Coronary heart disease (CHD) increases the risk of adverse outcomes from invasive pneumococcal disease. Methods: Using the 2020 and 2021 data from the national health interview survey, we identified adults with CHD. Chi-square analysis and logistic regression were used to examine factors that influence vaccination status. Results: There were 2675 participants aged 41 and above with CHD. Participants were predominantly white people (82.5%) and males (60.1%). The odds of receiving the pneumococcal vaccine increased with stepwise increase in comorbidities from 1 to 2 and from 2 to 3. Among individuals with ≥2 comorbidities, black people were less likely to be vaccinated compared with white people. Conclusion: Pneumococcal vaccine uptake among adults with CHD is determined by cumulative comorbidities and ethnicity.

Multicomponent interventions to improve routine childhood vaccine uptake in low and middle-income countries: a scoping review protocol

INTRODUCTION

Vaccine coverage remains inequitable globally. Many systematic reviews have looked at the effectiveness of strategies to improve vaccine uptake; however, these reviews frequently lack data from low and middle-income countries (LMICs), where evidence of cost-effective strategies is most valuable. This is partly because reviews often exclude non-randomised, observational or unpublished evaluations that are common in LMICs. Many reviews also exclude multicomponent interventions due to challenges isolating the effect of each component. A comprehensive mapping of multicomponent interventions implemented in LMICs would increase the visibility of studies excluded from systematic reviews and improve comparability of future evaluations by providing guidance for researchers on evaluation frameworks. This scoping review aims to identify, compare and summarise the properties and evaluation methods of multicomponent interventions to improve uptake of routine childhood vaccines in LMICs, and to assess the strengths and limitations of evaluation frameworks applied.

METHODS AND ANALYSIS

This review will be conducted using the Joanna Briggs Institute methodology for scoping reviews and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews guidelines. We will search the following databases: MEDLINE, Embase, PubMed, Cochrane, Eldis and Global Health (CAB Direct), Global Index Medicus, 3ie Portal, Google Scholar, COnnecting REpositories, and reference lists. One author will screen titles and abstracts and extract data from included articles using a pretested data extraction template. Uncertainties will be resolved through discussion with another author. Only studies published in English will be included for full review. We will assess the practicability, applicability, sensitivity and specificity of the evaluation frameworks used and present results using descriptive statistics, summary tables and charts.

ETHICS AND DISSEMINATION

Ethics approval is not required. The review will be submitted as part of a doctoral thesis, presented at conferences and published in peer-reviewed journals.

Effects of vaccination against COVID-19 on the emotional health of older adults

Background: The COVID-19 pandemic significantly impacted the mental and emotional health of the elderly, especially those from low to middle-income countries. However, COVID-19 vaccination may reduce this influence. Therefore, we aimed to estimate the effect of vaccination against COVID-19 on the emotional health of older adults. Methods: We selected a national, random, and stratified sample of non-hospitalized adults aged 60 to 79 years from Peru who intended to receive or had already received the COVID-19 vaccine during recruitment. During June and July 2021, the assessed outcomes were the fear, anxiety, and worry about COVID-19, general anxiety, and depression at baseline and after a month. We estimated the adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) for each altered emotional health outcomes in those who had one and two doses, compared with those who were not vaccinated using multilevel logistic regression with mixed effects. Results: We recruited 861 older adults with 20.8% of loss to follow-up. At baseline, 43.9% had received only one dose of the vaccine, and 49.1% had two doses. In the analysis during follow-up, those who had two doses had less fear (aOR: 0.19; CI 95%: 0.07 to 0.51) and anxiety to COVID-19 (aOR: 0.45; CI 95%: 0.22 to 0.89), compared to unvaccinated. We observed no effects in those with only one dose. Conclusions: Two doses of COVID-19 vaccination in older adults improves their perception of COVID-19 infection consequences. This information could be integrated into the vaccination campaign as an additional beneficial effect.

Novel intervention to promote COVID-19 protective behaviours among Black and South Asian communities in the UK: protocol for a mixed-methods pilot evaluation

INTRODUCTION

Culturally appropriate interventions to promote COVID-19 health protective measures among Black and South Asian communities in the UK are needed. We aim to carry out a preliminary evaluation of an intervention to reduce risk of COVID-19 comprising a short film and electronic leaflet.

METHODS AND ANALYSIS

This mixed methods study comprises (1) a focus group to understand how people from the relevant communities interpret and understand the intervention's messages, (2) a before-and-after questionnaire study examining the extent to which the intervention changes intentions and confidence to carry out COVID-19 protective behaviours and (3) a further qualitative study exploring the views of Black and South Asian people of the intervention and the experiences of health professionals offering the intervention. Participants will be recruited through general practices. Data collection will be carried out in the community.

ETHICS AND DISSEMINATION

The study received Health Research Authority approval in June 2021 (Research Ethics Committee Reference 21/LO/0452). All participants provided informed consent. As well as publishing the findings in peer-reviewed journals, we will disseminate the findings through the UK Health Security Agency, NHS England and the Office for Health Improvement and Disparities and ensure culturally appropriate messaging for participants and other members of the target groups.

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.

Associations Between General Vaccine Hesitancy and Healthcare Access Among Arkansans

BACKGROUND

Vaccines provide protection against numerous diseases that can cause serious illness and death. However, vaccine hesitancy threatens to undermine progress in reducing preventable diseases and illness. Vaccine hesitancy has been shown to vary by sociodemographic characteristics. However, studies examining associations between healthcare access and vaccine hesitancy are lacking.

OBJECTIVE

Using a statewide random sample of Arkansas adults, we examined the relationship between general vaccine hesitancy and healthcare access.

DESIGN

From July 12 to 30, 2021, participants were contacted by landlines and cellular phones using random digit dialing.

PARTICIPANTS

A total of 1500 Arkansas adults were surveyed. Black/African American and Hispanic/Latinx adults were oversampled to ensure adequate representation. The survey had a cooperation rate of 20%.

MAIN MEASURES

The dependent variable was an ordinal measure of general vaccine hesitancy. Age, gender, race, education, relationship status, and rural/urban residence were included in the model. Healthcare access was measured across four domains: (1) health insurance coverage; (2) having a primary care provider (PCP); (3) forgoing care due to cost; and (4) time since last routine checkup. The relationship between general vaccine hesitancy and healthcare access was modeled using ordinal logistic regression, controlling for sociodemographic characteristics.

KEY RESULTS

Mean age was 48.5 years, 51.1% were women, 28% reported a race other than White, and 36.3% held a bachelor's degree or higher. Those with a PCP and those with health insurance had approximately two-thirds the odds of being more hesitant ([OR=0.63, CI=0.47, 0.84] and [OR=0.68; CI=0.49, 0.94]) than those without a PCP and those without health insurance. Participants reporting a routine checkup in the last 2 years were almost half as likely to be more hesitant than those reporting a checkup more than 2 years prior (OR=0.58; CI=0.43, 0.79).

CONCLUSIONS

Results suggest improving access to health insurance, PCPs, and routine preventative care services may be critical to reducing vaccine hesitancy.

Associations between Influenza Vaccination and Health Care Access among Adults in the United States

Few studies have investigated the relationship between influenza vaccination and health care access. Furthermore, despite the well-documented disparities in vaccine coverage for communities of color, few studies have examined how experiences of discrimination may influence vaccine uptake. To fill this gap in the literature, this study examined associations between 5-year influenza vaccination rates and sociodemographic characteristics, health care access, and racial discrimination. Age, race/ethnicity, education, health care coverage, primary care provider, no medical care due to cost, and routine doctor checkups were significant correlates of 5-year influenza vaccination. In contrast to previous studies, discrimination scores were not a significant correlate of regular influenza vaccination. Respondents who reported forgoing care due to cost were less likely to report vaccination every year out of the last 5 years compared to all of the less frequent categories combined, demonstrating a more complex association between sometimes not being able to afford medical care and influenza vaccination. Future research should examine the relationship between influenza vaccination uptake, racial discrimination, and forgone care due to cost to enhance resources and messaging for influenza vaccination uptake.

Healthcare Access and Experiences of Racial Discrimination as Predictors of General Vaccine Hesitancy

The literature regarding vaccine hesitancy is limited to specific vaccines rather than general vaccine hesitancy. No studies have examined the relationship of general vaccine hesitancy to healthcare access and experiences of racial discrimination. This study fills gaps by examining: (1) socio-demographic factors; (2) associations between healthcare access; and (3) experiences with racial discrimination and general vaccine hesitancy. Survey data were obtained from 2022 US adults from 7 September to 3 October 2021. Racial and ethnic minority populations were oversampled. Age, gender, race, and education were predictors of vaccine hesitancy. Asian respondents had less than two-thirds the odds of being vaccine hesitant. Healthcare access was associated with vaccine hesitancy. Not having health insurance coverage, not having a primary care provider, and not seeing a provider for a routine check-up in the past two years were associated with higher vaccine hesitancy. For every one-point increase in racial discrimination score (0-45), the odds of being more vaccine hesitant increased by a factor of 1.03. The findings demonstrate that policy, systems, and environmental factors are critical to addressing vaccine hesitancy. Given the associations between vaccine hesitancy and racial discrimination and healthcare access, more attention should be given to inequities in the healthcare systems in order to address vaccine hesitancy.

Understanding Drivers of Vaccine Hesitancy During the COVID-19 Pandemic Among Older Adults in Jiangsu Province, China: Cross-sectional Survey

BACKGROUND

Older adults are particularly at risk from infectious diseases, including serve complications, hospitalization, and death.

OBJECTIVE

This study aimed to explore the drivers of vaccine hesitancy among older adults based on the "3Cs" (confidence, complacency, and convenience) framework, where socioeconomic status and vaccination history played the role of moderators.

METHODS

A cross-sectional questionnaire survey was conducted in Jiangsu Province, China, between June 1 and July 20, 2021. Older adults (aged ≥60 years) were recruited using a stratified sampling method. Vaccine hesitancy was influenced by the 3Cs in the model. Socioeconomic status and vaccination history processed through the item parceling method were used to moderate associations between the 3Cs and hesitancy. Hierarchical regression analyses and structural equation modeling were used to test the validity of the new framework. We performed 5000 trials of bootstrapping to calculate the 95% CI of the pathway's coefficients.

RESULTS

A total of 1341 older adults participated. The mean age was 71.3 (SD 5.4) years, and 44.7% (599/1341) of participants were men. Confidence (b=0.967; 95% CI 0.759-1.201; P=.002), convenience (b=0.458; 95% CI 0.333-0.590; P=.002), and less complacency (b=0.301; 95% CI 0.187-0.408; P=.002) were positively associated with less vaccine hesitancy. Socioeconomic status weakened the positive effect of low complacency (b=-0.065; P=.03) on low vaccine hesitancy. COVID-19 vaccination history negatively moderated the positive association between confidence (b=-0.071; P=.02) and lower vaccine hesitancy.

CONCLUSIONS

Our study identified that confidence was the more influential dimension in reducing vaccine hesitancy among older adults. COVID-19 vaccination history, as well as confidence, had a positive association with less vaccine hesitancy and could weaken the role of confidence in vaccine hesitancy. Socioeconomic status had a substitution relationship with less complacency, which suggested a competitive positive association between them on less vaccine hesitancy.

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.

The intersection of gender and race in older adults' decision to receive COVID-19 vaccines

COVID-19 vaccines are essential public health tools for protecting older adults, who are at high risk of severe outcomes associated with COVID-19. Little is known, however, about how older adults approach the decision to receive a COVID-19 vaccine. We hypothesized that intersections between gender and race may provide unique insight into the decision-making process and the factors that lead to vaccine uptake among hesitant individuals. We performed in-depth interviews with 24 older adults who had been vaccinated against COVID-19 and used the framework approach with an intersectional lens to analyze data. Two typologies emerged: eager compliers did not question the need to vaccinate, whereas hesitant compliers were skeptical of the vaccine and underwent a thorough decision-making process prior to vaccination. For eager compliers, the vaccine offered protection from a disease that posed a serious threat, and few risks were perceived. In contrast, hesitant compliers perceived risks associated with the vaccine product or mistrusted the infrastructure that led to rapid vaccine development. Hesitancy was greater among Black participants, and only Black participants reported mistrust in vaccine infrastructure. At the intersection of gender and race, a 'White male effect' was observed, whereby White men perceived the fewest risks associated with the vaccine, and Black women were the most fearful of serious side effects. Nearly all hesitant compliers ultimately got vaccinated due to the threat of COVID-19. Convenient access through vaccine clinics in senior's buildings was pivotal for hesitant compliers and external and internal influences had differential impacts by race and gender. Emphasizing the risk of COVID-19, convenient and accessible opportunities for vaccination, and messages that are targeted to specific groups are likely to increase vaccine uptake among older adults.

Drivers of and barriers to routine adult vaccination: A systematic literature review

We performed a systematic literature review in PubMed and Embase (2016-2021) to investigate the drivers of and barriers to routine vaccination in adults aged 50 and older globally. A thematic assessment identified three categories across 61 publications: sociodemographic, health-related, and attitudinal. The most common sociodemographic determinants (factors identified in studies; n = 47) associated with vaccination uptake were economic status, age, education, and household composition, which had mixed effects on vaccine uptake. For health-related determinants (n = 27), individuals with comorbidities and health care consumption were the most common factors, both increased vaccine uptake. The most common attitudinal factors (n = 42) were self-efficacy, provider or other's recommendations, and vaccine-preventable disease awareness; across studies, all attitude factors had a positive effect, unlike the sociodemographic and health status categories. Findings suggest that patient and provider awareness and education campaigns are effective ways to increase uptake of routine vaccinations in older adults.

The effect of vaccination beliefs regarding vaccination benefits and COVID-19 fear on the number of vaccination injections

The Coronavirus disease pandemic of 2019 is a vast worldwide public health hazard, impacting people of all ages and socioeconomic statuses. Vaccination is one of the most effective methods of controlling a pandemic like COVID-19. This study aims to investigate the relationship between the number of vaccination injections and fear of COVID-19 and test whether beliefs benefit from vaccination COVID-19 mediate the effect of fear of COVID-19 on the number of vaccination injections. A total of 649 Vietnamese adults were enrolled online to finish answering, including scales The Health Belief Model (HBM) and The Fear of COVID-19 (FCV-19S), consisting of 340 (52.4%) males and 309 (47.6%) females. The data were analyzed using variance, regression, and a simple mediation model. The total score of COVID-19 fear was M = 22.26, SD = 5.49. Vietnamese fear of COVID-19 was at a medium level. Our results suggest that 18- to 20-year-olds are more fearful of COVID-19 than others. People who received the first dosage exhibited a greater fear of COVID-19 than those who received the second dose and were not inoculated. Additionally, the beliefs benefit of vaccination COVID-19 has a role in the relationship between the number of vaccination injections and fear of COVID-19. During the pandemic, adults in Vietnam are more afraid of COVID-19 than during prior outbreaks. Besides, the Vietnamese populace demonstrated a considerable demand for and high acceptability of the COVID-19 vaccine. The current study indicates that psychological counselors and therapists should counsel clients on the value of vaccination and address the fear of COVID-19 as public understanding of the benefits of vaccines increases. To further clarify the effect of this issue on the correlation between fear of COVID-19 and the number of vaccinations, the results of this study indicate that the existing vaccine communication factor for COVID-19 vaccination should be modified to increase confidence in the benefits of immunization.

Planning and Organization of the COVID-19 Vaccination Campaign: An Overview of Eight European Countries

The initial progress of the COVID-19 vaccination campaign worldwide depended on several aspects, including programmatic/practical issues. This paper focused on the planning and organization of COVID-19 vaccination campaigns in eight European countries (Sweden, Denmark, Romania, Hungary, Italy, Spain, Germany, and France), from the launch to August 2021. Information on the planning of the vaccination campaign (release and update of a national immunization plan, types of vaccines being used and their limitations/suspensions) and its organization (vaccination target groups, possibility of citizens' choice, vaccination workforce and settings, vaccines procurement) were obtained through desk research of international and national reports, plans, and websites. Eventually, data on vaccination coverage were drawn from Our world in data and analyzed through join point regression. The eight countries showed differences in groups prioritization, limitations/suspensions of use of specific vaccines, citizens' possibility to choose vaccines, and vaccination workforce involved. These issues could have contributed to the different progress towards high levels of vaccination coverage. In respect to vaccination coverage, Romania reached much lower levels than other countries. Further comparative research is needed in order to identify best practices in vaccination campaign that could be useful for the next phases of the COVID-19 pandemic, and be better prepared for future potential pandemic.

Racism as the fundamental cause of ethnic inequities in COVID-19 vaccine hesitancy: A theoretical framework and empirical exploration using the UK Household Longitudinal Study

Ethnic inequities in COVID-19 vaccine hesitancy have been reported in the United Kingdom (UK), and elsewhere. Explanations have mainly focused on differences in the level of concern about side effects, and in lack of trust in the development and efficacy of vaccines. Here we propose that racism is the fundamental cause of ethnic inequities in vaccine hesitancy. We introduce a theoretical framework detailing the mechanisms by which racism at the structural, institutional, and interpersonal level leads to higher vaccine hesitancy among minoritised ethnic groups. We then use data from Wave 6 of the UK Household Longitudinal Study COVID-19 Survey (November to December 2020) to empirically examine these pathways, operationalised into institutional, community, and individual-level factors. We use the Karlson-Holm-Breen method to formally compare the relationship between ethnicity and vaccine hesitancy once age and gender, sociodemographic variables, and institutional, community, and individual-level factors are accounted for. Based on the Average Partial Effects we calculate the percentage of ethnic inequities explained by each set of factors. Findings show that institutional-level factors (socioeconomic position, area-level deprivation, overcrowding) explained the largest part (42%) of the inequity in vaccine hesistancy for Pakistani or Bangladeshi people, and community-level factors (ethnic density, community cohesion, political efficacy, racism in the area) were the most important factors for Indian and Black groups, explaining 35% and 15% of the inequity, respectively. Our findings suggest that if policy intervened on institutional and community-level factors - shaped by structural and institutional racism - considerable success in reducing ethnic inequities might be achieved.

Exploring COVID-19 Vaccine Confidence with People from Black and Asian Backgrounds in England

Aims

Little research has examined factors underlying COVID-19 vaccine hesitancy or refusal in Black and Asian individuals in England, among whom hesitancy tends to be higher than in the general population. This qualitative study aimed to gain an understanding of factors affecting hesitancy in Black and Asian individuals in England, to help address concerns about having the vaccine.

Method

Ninety-five participants (51 women, 42 men, 2 other; 58% were aged between 30 and 49) recruited via a market recruitment agency, local Healthwatch networks, and using a snowballing method, participated in four activities on an online engagement platform, sharing their attitudes towards the COVID-19 vaccine roll-out, and factors shaping their beliefs and concerns, over 5 weeks from April to March 2021.

Results

Inductive thematic analysis revealed five themes: (1) a variety of views on the COVID-19 vaccine, (2) targeted messaging for Black and Asian people as counterproductive, (3) confusion over the purpose of the vaccine roll-out, (4) hesitancy to take the vaccine, and (5) local networks as a trusted source of information.

Conclusions

Our findings suggest that respecting individuals’ agency, transparency of information provided, and the independence of the bodies providing this information are important. Instead of targeted messaging, local networks should be used in campaigns to increase COVID-19 vaccine uptake among Black and Asian individuals.

Nur MA, Mohamed FY. COVID-19 Vaccine Coverage and Potential Drivers of Vaccine Uptake among Healthcare Workers in SOMALIA: A Cross-Sectional Study

Healthcare workers (HCWs) are one of the most vulnerable groups for contracting COVID-19 and dying as a result of it. Over 10,000 HCWs in Africa have been infected with COVID-19, according to the World Health Organization, making it a substantial occupational health threat for HCWs. To that end, Somalia’s Ministry of Health has ordered that all healthcare personnel obtain the COVID-19 vaccination to safeguard themselves and the community they serve. In this investigation, we aimed to assess the COVID-19 vaccination coverage and its associated factors among healthcare workers in Somalia. A cross-sectional study was employed to examine COVID-19 vaccination coverage among healthcare personnel in Somalia. The data were obtained via an online questionnaire supplied by Google forms between December 2021 and February 2022, where a total of 1281 healthcare workers from the various federal states of Somalia were recruited. A multinomial regression analysis was used to analyse the factors associated with COVID-19 vaccine uptake. Overall, 1281 HCWs participated (630 females, 651 males) with a mean age and standard deviation of 27.7 years ± 7.1. The overall vaccine coverage was 37.4%. Sex, age, the state of residency, education level, specialization, hospital COVID-19 policy, vaccine availability at the centre, COVID-19 treatment centre, and health facility level were the factors that influenced the COVID-19 vaccine uptake among health professionals in Somalia. Male healthcare employees were 2.2 times (odds ratio-OR = 2.2; confidence interval-CI: 1.70, 2.75, p < 0.001) more likely than female healthcare workers to be fully vaccinated. The survey discovered that the COVID-19 vaccine coverage among health professionals was quite low, with the major contributing factors being accessibility, security challenges and literary prowess. Additional efforts to enhance vaccination uptake are needed to improve the COVID-19 vaccination coverage.

Geographical variation of COVID-19 vaccination coverage, ethnic diversity and population composition in Flanders

The vaccination coverage in Flanders is high, but some regions show lower vaccination willingness as compared to the overall vaccination coverage. Beginning November of 2021, the vaccination rate in Flanders was above 93% in age groups above 45 years, and around 85% in the age groups 12 to 44 years. Apart from Flanders as a whole, focus here is on the health sector Maasland, which has a slightly lower vaccination rate, especially in the age groups 12 to 44 years. In the Maasland region, located on the eastern border of Flanders, there are between 1% and 10% less vaccinated individuals than expected according to the vaccination rate in the whole of Flanders, with lowest vaccination rates in the south of the Maasland region. We study the impact of ethnic diversity in the population, population composition with respect to the ethnicity of individuals (in the sense of how the local population composition differs from the Flemish average), and socio-economic status on the vaccination rate at the level of the statistical sector, apart from the effect of age. We explain the statistical methods to investigate geographical differences and illustrate how one can deal with incomplete information in vaccination registries. Ethnic diversity in a region is associated with lower vaccination rates, as is a lower regional socio-economic status. The composition of the population in Maasland is associated with a 35% reduction in the odds to get vaccinated as compared to the overall Flemish population.

Associations between 5-year influenza vaccination and sociodemographic factors and healthcare access among Arkansans

Despite wide availability, only 50.2% of the United States (US) adult population and 50.3% of adult Arkansans were vaccinated for influenza during the 2020-2021 influenza season. The proportion of the population vaccinated for influenza varies by age, sex, race/ethnicity, education, rural/urban residence, and income. However, measures of healthcare access have not been adequately investigated as predictors of influenza vaccination. Using a large, statewide random sample, this study examined 5-year influenza vaccination among Arkansans by sociodemographic characteristics (age, sex, race/ethnicity, education, rural/urban residence), general vaccine hesitancy, and healthcare access (having a primary care provider, having health insurance, forgoing health care due to cost, and frequency of doctor checkups). Older age, being female, being Hispanic, having a bachelor's degree or higher, having a primary care provider, visiting a doctor for a checkup in the past two years, and lack of hesitancy towards vaccines were significant predictors of receiving influenza vaccination.

Public knowledge, attitude, and acceptance toward COVID-19 vaccines in Palestine: a cross-sectional study

BACKGROUND

The consequences of the COVID-19 pandemic on physical and mental health in addition to the global economy are huge. Vaccination is a pivotal measure to decrease COVID-19 morbidity and mortality and to help bring the pandemic under control. Yet, success of the vaccination process depends on the population's willingness to be vaccinated which may be determined by their level of knowledge about and trust in currently available COVID-19 vaccines. Therefore, this study aims to assess the knowledge, attitude, and acceptance of Palestinians towards COVID-19 vaccines.

METHODS

A national cross-sectional study was distributed in different Palestinian regions to assess the knowledge and attitude of Palestinians toward COVID-19 vaccines using an online questionnaire, it included three sections; sociodemographic characteristics, knowledge assessment questions, and attitude assessment questions.

RESULTS

A total of 6226 participants completed the questionnaire; among them, 41.36% believed that vaccines are safe, 69.02% agreed that vaccines are vital to protect from COVID-19; in addition, 55.1% approve administering the vaccine once available, and 37.86% do not believe their benefits outweigh the risks. The Source of information for 22.07% of participants in social media, while 11.92% rely on health care providers. Participants' attitudes and knowledge were significantly affected by gender, governorate, age, education level, and marital status (P <0.001).

CONCLUSION

The findings suggest that there is good knowledge and attitude toward the vaccination process against COVID-19 in Palestine, although low acceptance was detected. Awareness campaigns are required to spread reliable knowledge about COVID-19 vaccines.

Association between COVID-19 vaccine hesitancy and generalized trust, depression, generalized anxiety, and fear of COVID-19

Background

Although numerous studies have been published on the predictors of COVID-19 vaccine hesitancy, some possible predictors remain underexplored. In this study, we explored the associations of unwillingness and indecisiveness regarding COVID-19 vaccination with generalized trust, mental health conditions such as depression and generalized anxiety, and fear of COVID-19.

Methods

Data of wave 1 (from October 27 till November 6, 2020) and wave 3 (from April 23 till May 6, 2021) of a longitudinal online study conducted in Japan were used for the analyses. Unvaccinated participants were asked at wave 3 about their willingness to be vaccinated, with possible responses of willing, unwilling, or undecided. These three responses were used as the outcome variable, and multinomial logistic regression analyses were conducted with willingness to be vaccinated as the reference group. Explanatory variables included generalized trust, depression, generalized anxiety, and fear of COVID-19 both at wave 1 and 3, and sociodemographic and health-related variables.

Results

Of the 11,846 valid respondents, 209 (1.8%) answered that they had already been vaccinated against COVID-19, 7089 (59.8%) responded that they were willing to be vaccinated, 3498 (29.5%) responded that they were undecided, and 1053 (8.9%) responded that they were unwilling to be vaccinated. After adjusting for covariates, we found that: (1) participants with lower levels of generalized trust at wave 1 and 3 were more likely to be undecided or unwilling at wave 3; (2) respondents with moderately severe or severe depression at wave 1 and 3 were more likely to be undecided at wave 3; (3) participants with moderate or severe levels of generalized anxiety at wave 3 but not at wave 1 were more likely to be unwilling at wave 3; and (4) respondents with high levels of fear of COVID-19 at wave 1 and 3 were less likely to be undecided and unwilling at wave 3.

Conclusions

Generalized trust, mental health conditions such as depression and generalized anxiety, and low level of fear of COVID-19 are associated with unwillingness or indecision regarding being vaccinated against COVID-19.
