COVID-19 vaccination intention and behavior in a large, diverse, U.S. refugee population

Predictors of COVID-19 vaccine acceptability among refugees and other migrant populations: A systematic scoping review

OBJECTIVE

This study aimed to map the existing literature to identify predictors of COVID-19 vaccine acceptability among refugees, immigrants, and other migrant populations.

METHODS

A systematic search of Medline, Embase, Scopus, APA PsycInfo and Cumulative Index of Nursing and Allied Health Literature (CINAHL) was conducted up to 31 January 2023 to identify the relevant English peer-reviewed observational studies. Two independent reviewers screened abstracts, selected studies, and extracted data.

RESULTS

We identified 34 cross-sectional studies, primarily conducted in high income countries (76%). Lower vaccine acceptance was associated with mistrust in the host countries' government and healthcare system, concerns about the safety and effectiveness of COVID-19 vaccines, limited knowledge of COVID-19 infection and vaccines, lower COVID-19 risk perception, and lower integration level in the host country. Female gender, younger age, lower education level, and being single were associated with lower vaccine acceptance in most studies. Additionally, sources of information about COVID-19 and vaccines and previous history of COVID-19 infection, also influence vaccine acceptance. Vaccine acceptability towards COVID-19 booster doses and various vaccine brands were not adequately studied.

CONCLUSIONS

Vaccine hesitancy and a lack of trust in COVID-19 vaccines have become significant public health concerns within migrant populations. These findings may help in providing information for current and future vaccine outreach strategies among migrant populations.

Longitudinal attenuation in political polarization: Evidence from COVID-19 vaccination adherence in Brazil

BACKGROUND

While political polarization in policy opinions, preferences, and observance is well established, little is known about whether and how such divisions evolve, and possibly attenuate, over time. Using the COVID-19 pandemic in Brazil as the backdrop, we examine the longitudinal evolution of a highly relevant and polarizing policy: adherence to the COVID-19 vaccination.

METHODS

Studies 1 (N = 3346) and 2 (N = 10,214) use nationwide surveys to document initial differences and subsequent changes in vaccination adherence between conservatives ("Bolsonaristas") and non-conservatives ("non-Bolsonaristas"). Study 3 (N = 742) uses an original dataset to investigate belief changes among conservatives and their association with asymmetric changes in vaccination adherence.

RESULTS

Despite substantial differences at the early stages of rollout, the gap in vaccination adherence between conservatives and non-conservatives significantly decreased with the passage of time, driven essentially by a much faster uptake among the initially most skeptic-the conservatives. Study 3 demonstrates that the asymmetric changes in vaccination adherence were associated with meaningful belief changes among the conservatives, especially about the perceived effectiveness of the COVID-19 vaccines and the expected adherence of peers to the vaccination campaign.

CONCLUSIONS

Together, these studies show that, in a context where the superiority of the promoted policy becomes clear over time and individuals have the opportunity to revisit prior beliefs, even intense political polarization can be attenuated.

COVID-19 vaccine uptake among non-US-born populations in the United States, 2020-2022

BACKGROUND

In the United States (US), COVID-19 vaccination rates among non-US-born individuals (i.e., refugees, immigrants, and migrants [RIM]) are variable. Understanding baseline COVID-19 vaccine coverage among these populations and determining if disparities exist is essential for quality improvement initiatives and public health interventions.

METHODS

Baseline COVID-19 vaccination rates for both primary series and booster doses were calculated at four health systems located in Minnesota, Colorado, and Pennsylvania participating in the Minnesota Department of Health's Center of Excellence in Newcomer Health. Patients aged ≥5 years as of 1/1/22, seen for ≥1 primary care visit during 7/1/2019-6/30/22 were included. Descriptive statistics were calculated for three measures of COVID-19 vaccine coverage during 12/14/2020-6/30/2022: 1) initiation of primary series; 2) completion of primary series; 3) completion of first booster. We calculated vaccine coverage rates for the entire population and stratified by subgroup including country of origin, refugee status, and primary language preference.

RESULTS

We included 1,624,573 patients eligible for COVID-19 primary series vaccine and 907,749 eligible for COVID-19 booster vaccination. The percent of eligible patients who completed a COVID-19 primary series (63.4 %) and booster dose (66.2 %) were similar. Completion of the primary series was higher for non-US-born persons (72.7 %) compared with US born persons (65.4 %), similar among refugees (63.5 %) and non-refugees (63.4 %), and lower in patients with language preference other than English (62.7 %) compared with English preferring patients (63.6 %). Booster completion was lower for non-US-born persons (61.8 %), refugees (46.7 %), and patients with language preference other than English (55.3 %) compared with US-born (70 %), non-refugees (66.3 %), and English preferring patients (67.3 %) respectively.

CONCLUSIONS

This evaluation identified disparities in COVID-19 vaccination rates among non-US-born persons and persons with a language preference other than English living in the US. Targeted outreach efforts may be beneficial in reaching these populations.

COVID-19 vaccine acceptance in the general population and under-resourced communities from high-income countries: realist review

OBJECTIVE

To compare vaccination willingness before rollout and 1 year post-rollout uptake among the general population and under-resourced communities in high-income countries.

DESIGN

A realist review.

DATA SOURCES

Embase, PubMed, Dimensions ai and Google Scholar.

SETTING

High-income countries.

DEFINITIONS

We defined vaccination willingness as the proportion of participants willing or intending to receive vaccines prior to availability. We defined vaccine uptake as the real proportion of the population with complete vaccination as reported by each country until November 2021.

RESULTS

We included data from 62 studies and 18 high-income countries. For studies conducted among general populations, the proportion of vaccination willingness was 67% (95% CI 62% to 72%). In real-world settings, the overall proportion of vaccine uptake among those countries was 73% (95% CI 69% to 76%). 17 studies reported pre-rollout willingness for under-resourced communities. The summary proportion of vaccination willingness from studies reporting results among people from under-resourced communities was 52% (95% CI 0.46% to 0.57%). Real-world evidence about vaccine uptake after rollout among under-resourced communities was limited.

CONCLUSION

Our review emphasises the importance of realist reviews for assessing vaccine acceptance. Limited real-world evidence about vaccine uptake among under-resourced communities in high-income countries is a call to context-specific actions and reporting.

'Getting control of Corona takes many angles': COVID-19 vaccine knowledge, attitudes and beliefs among refugee/immigrant/migrant communities in four US cities

The objectives of the study were to (i) document refugee, immigrant and migrant (RIM) communities' knowledge, attitudes and beliefs (KABs) related to the Coronavirus disease (COVID-19) vaccine and (ii) identify best practices for developing and disseminating culturally and linguistically responsive health messaging addressing those KABs. Thirteen online focus groups (OFGs) in 10 languages were conducted. Each OFG was conducted in the participants' native language. OFGs were recorded, transcribed, translated and uploaded to qualitative software for coding. A thematic analysis was conducted. Results suggest that while there was some variation between different language groups (e.g. whether religious leaders were seen as trusted sources of information about COVID), there were also important commonalities. Most language groups (i) alluded to hearing about or having gaps in knowledge about COVID-19/the COVID-19 vaccine, (ii) reported hearing negative or conflicting stories about the vaccine and (iii) shared concerns about the negative side effects of the vaccine. There continues to be a need for health messaging in RIM communities that is culturally and linguistically concordant and follows health literacy guidelines. Message content about the COVID-19 vaccine should focus on vaccine importance, effectiveness and safety, should be multimodal and should be primarily delivered by healthcare professionals and community members who have already been vaccinated.

The experiences of community health workers when communicating with refugees about COVID-19 vaccines in Syracuse, NY: A qualitative study

Background

Refugees are among the most health-vulnerable members of society. Despite the importance of vaccination to mitigate the risks associated with COVID-19 infection, ensuring adequate access and uptake of the COVID-19 vaccine remains a pressing concern for refugee populations. Research has suggested that community-oriented approaches and open communication with trusted individuals are essential to address this challenge. Vaccine outreach efforts were performed in Syracuse, NY, by Community Health Workers (CHWs) as trusted refugee community members. This study explored CHWs' experiences during vaccine outreach and perceptions about COVID-19 vaccine hesitancy and acceptance among refugees, including barriers and facilitators to vaccination.

Methods

A qualitative study was performed using thematic analysis following six semi-structured interviews with CHWs.

Results

Four main themes supported by 16 sub-themes were extracted. CHWs described the (1) diverse beliefs and attitudes of refugees by ethnic group, with most having low vaccine acceptance at first. (2) Barriers included contextual barriers, lack of awareness, misinformation, and withdrawal when forced from vaccine mandates. However, CHWs also identified numerous (3) facilitators to vaccination, including the internal processing and eventual vaccine acceptance, supported by external messaging by CHWs and time. Culturally sensitive intervention strategies occurred through (4) CHW team efforts and their provision of reliable information to refugee clients, with openness and over time. The team efforts of CHWs significantly contributed to refugee acceptance and uptake of the COVID-19 vaccine.

Conclusions

This study revealed how the refugee population changed their belief towards the COVID-19 vaccine through trust, time, and reliable information provided by CHWs and describes culturally sensitive strategies for vaccine uptake by refugees. CHWs' reflection on COVID-19 vaccine hesitancy and acceptance among refugees during outreach efforts is an essential perspective when implementing future public health interventions.

Co-designing a theory-informed, multicomponent intervention to increase vaccine uptake with Congolese migrants: A qualitative, community-based participatory research study (LISOLO MALAMU)

INTRODUCTION

Disparities in the uptake of routine and COVID-19 vaccinations have been observed in migrant populations, and attributed to issues of mistrust, access and low vaccine confidence. Participatory research approaches and behaviour change theory hold the potential for developing tailored vaccination interventions that address these complex barriers in partnership with communities and should be explored further.

METHODS

This study used a theory-informed, community-based participatory research approach to co-design a culturally tailored behaviour change intervention aimed at increasing COVID-19 vaccine uptake among Congolese migrants in London, United Kingdom (2021-2022). It was designed and led by a community-academic partnership in response to unmet needs in the Congolese community as the COVID-19 pandemic started. Barriers and facilitators to COVID-19 vaccination, information and communication preferences, and intervention suggestions were explored through qualitative in-depth interviews with Congolese migrants, thematically analysed, and mapped to the theoretical domains framework (TDF) and the capability, opportunity, motivation, behaviour model to identify target behaviours and strategies to include in interventions. Interventions were co-designed and tailored in workshops involving Congolese migrants.

RESULTS

Thirty-two Congolese adult migrants (24 (75%) women, mean 14.3 (SD: 7.5) years in the United Kingdom, mean age 52.6 (SD: 11.0) years) took part in in-depth interviews and 16 (same sample) took part in co-design workshops. Fourteen barriers and 10 facilitators to COVID-19 vaccination were identified; most barrier data related to four TDF domains (beliefs about consequences; emotion; social influences and environmental context and resources), and the behavioural diagnosis concluded interventions should target improving psychological capability, reflective and automatic motivations and social opportunities. Strategies included culturally tailored behaviour change techniques based on education, persuasion, modelling, enablement and environmental restructuring, which resulted in a co-designed intervention comprising community-led workshops, plays and posters. Findings and interventions were disseminated through a community celebration event.

CONCLUSIONS

Our study demonstrates how behavioural theory can be applied to co-designing tailored interventions with underserved migrant communities through a participatory research paradigm to address a range of health issues and inequalities. Future research should build on this empowering approach, with the goal of developing more sensitive vaccination services and interventions which respond to migrant communities' unique cultural needs and realities.

PATIENT OR PUBLIC CONTRIBUTION

Patient and public involvement (PPI) were embedded in the participatory study design and approach, with community members co-producing all stages of the study and co-authoring this paper. An independent PPI board (St George's Migrant Health Research Group Patient and Public Involvement Advisory Board) comprising five adult migrants with lived experience of accessing healthcare in the United Kingdom were also consulted at significant points over the course of the study.

Attitudes and perceptions toward COVID-19 virus and vaccines among a Somali population in Northern Wisconsin

OBJECTIVES

The study's aim was to gain a qualitative understanding of vaccine beliefs and attitudes toward COVID-19 among Somali residents living in Northern Wisconsin (WI). While vaccination rates are significantly lower among Black and Hispanic populations, those with lower educational levels, and in rural areas, minimal is known about Somali population perspectives of COVID-19 vaccination rates.

METHODS

Through qualitative methodology employing focus groups for data collection and the inclusion of Somali interpreters, we explored Somali community viewpoints regarding these topics. Focus group interviews were transcribed verbatim with subsequent transcripts reviewed and analyzed by the research team to identify themes.

RESULTS

The overarching theme was Protecting self, others, and community. Most participants accepted vaccinations, and the COVID-19 vaccine specifically, to protect themselves, others, and their community. Factors contributing to vaccine update included trusting local messengers, including public health nurses; valuing collective memory associated with previous communicable disease outbreaks; believing religion supported vaccine protective actions; and following recommended government and media advice.

CONCLUSION

Study results suggest strategies for increasing community outreach to newly resettled refugee and immigrant minority groups, establishing trust between community members, nurses, and other public health personnel, and facilitators for connecting health messaging to Somali cultural and religious beliefs to promote public health and safety.

Covid-19 Vaccine Hesitancy and Under-Vaccination among Marginalized Populations in the United States and Canada: A Scoping Review

BACKGROUND

Amid persistent disparities in Covid-19 vaccination and burgeoning research on vaccine hesitancy (VH), we conducted a scoping review to identify multilevel determinants of Covid-19 VH and under-vaccination among marginalized populations in the U.S. and Canada.

METHODS

Using the scoping review methodology developed by the Joanna Briggs Institute, we designed a search string and explored 7 databases to identify peer-reviewed articles published from January 1, 2020-October 25, 2022. We combine frequency analysis and narrative synthesis to describe factors influencing Covid-19 VH and under-vaccination among marginalized populations.

RESULTS

The search captured 11,374 non-duplicated records, scoped to 103 peer-reviewed articles. Among 14 marginalized populations identified, African American/Black, Latinx, LGBTQ+, American Indian/Indigenous, people with disabilities, and justice-involved people were the predominant focus. Thirty-two factors emerged as influencing Covid-19 VH, with structural racism/stigma and institutional mistrust (structural)(n = 71) most prevalent, followed by vaccine safety (vaccine-specific)(n = 62), side effects (vaccine-specific)(n = 50), trust in individual healthcare provider (social/community)(n = 38), and perceived risk of infection (individual)(n = 33). Structural factors predominated across populations, including structural racism/stigma and institutional mistrust, barriers to Covid-19 vaccine access due to limited supply/availability, distance/lack of transportation, no/low paid sick days, low internet/digital technology access, and lack of culturally- and linguistically-appropriate information.

DISCUSSION

We identified multilevel and complex drivers of Covid-19 under-vaccination among marginalized populations. Distinguishing vaccine-specific, individual, and social/community factors that may fuel decisional ambivalence, more appropriately defined as VH, from structural racism/structural stigma and systemic/institutional barriers to vaccination access may better support evidence-informed interventions to promote equity in access to vaccines and informed decision-making among marginalized populations.

A Cervical Cancer Screening Toolkit for Somali Women: A Pilot Randomized Controlled Trial

This study aims to determine whether a novel cervical cancer screening toolkit will increase rates of pap test completion and HPV vaccination among Somali women living in the United States. We conducted a randomized controlled, pilot trial from June 2021 to February 2022. Somali women aged 21 to 70 were randomized to either receive a toolkit (infographic, video and an in-person health seminar) or not. Health passports confirming a completed pap test and/or HPV vaccination by clinician signature were used to measure outcomes. The primary outcome was pap test completion and the secondary outcome was HPV vaccination. We enrolled 57 participants. Patients randomized to the treatment arm were significantly more likely to have had a pap test (53.7% vs. 3.7%, p < 0.0001) and were also more likely to have received the HPV vaccine (10.7% vs. 3.7%, p = 0.6110). This toolkit increased rates of pap test completion and more participants in the intervention arm received HPV vaccination, though numbers were low. The study design may serve as a reproducible model to determine the effectiveness of patient education materials.

Barriers to COVID-19 vaccine uptake: classification and the role of Health Literacy and Media Literacy

Background

Vaccination is one of the most influential and cost-effective health interventions for preventing and reducing COVID-19 diseases. Unfortunately, the majority of the world's population is deprived of vaccination. Health Literacy (HL) and Media Literacy (ML) are essential to the COVID-19 vaccination. The present study investigates the barriers to COVID-19 vaccine uptake, focusing on classification and the roles of HL and ML.

Methods

A cross-sectional study was conducted among people 18-65 years old in Sarab City, located in East Azerbaijan, Iran, between September to October 2020. Multistage cluster sampling was employed to recruit 298 people from Health Care Services Centers (HCCs).

Results

The results of this research demonstrated that about 32.6% of participants reported that they have fully injected COVID-19 vaccines. Also, HL was positively associated with ML (r = 0.214, p < 0.05). Barriers of COVID-19 vaccine uptake were classified into personal, interpersonal, group and organizational, society and decision-making factors. Besides, barriers to the COVID-19 vaccine were significantly correlated with HL (r = -0.298, p < 0.05) and ML (r = 0.266, p < 0.05). Additionally, in the hierarchical regression model, demographic characteristics accounted for 8.2% of the variation in barriers to the COVID-19 vaccine (F = 4.34; p = 0.001), that monthly income (ß = -0.237; p < 0.05) and marriage statues (ß = 0.131; p < 0.05) were statistically associated with low barriers. HL as predictor variables explained an additional 14.4% of variation in barriers of COVID-19 vaccine (F = 53.84; p < 0.001) and ML explained an extra 9.2% of the variation (F = 38.83; p < 0.001). In total, demographic characteristics, HL dimensions and ML were able to explain 31.8% of the variation in barriers to COVID-19 vaccine.

Conclusions

According to the findings, various strategies are needed to increase the COVID-19 vaccination uptake. This is due to the fact that barriers to COVID-19 vaccination uptake are multifactorial. These facts can help health policymakers and healthcare providers design media-based interventions to reduce barriers to COVID-19 vaccination uptake among adults. Enhancing vaccine HL and ML for adults and improving vaccine confidence are of high priority.

A formative research to explore the programmatic approach of vaccinating the Rohingya refugees and host communities against COVID-19 infection in Bangladesh

BACKGROUND

The vaccination of the Rohingya refugees and host communities against COVID-19 in Cox's Bazar started in August 2021. Government authorities and Non-Government Organisation partners implemented a project around the initial period of vaccination to improve awareness and access to target beneficiaries. We conducted formative research to understand the programmatic approach of this project and identify potential challenges and community perceptions regarding immunisation against COVID-19.

METHODOLOGY

This was formative research in which we used a qualitative method of data collection. Purposively chosen 12 key-informant interviews and conveniently chosen 20 in-depth interviews were conducted using semi-structured interview guidelines from August to September 2022 in the Rohingya camp and host communities of Cox's Bazar District, Bangladesh. Ethical approval was obtained from the North South University Institutional Review Board, and written informed consent was obtained from all the participants. We used a thematic analysis approach to analyse the data.

RESULTS

The project neither provided any promotional or tailored messages regarding the COVID-19 vaccine nor conducted any vaccine hesitancy surveys before implementing the project. The project did not provide any storage facilities for the vaccines' cold chain management but provided transport support to carry the vaccines from the district to the sub-district level. Community leaders were included in the decision-making process during local-level planning of the vaccination programme. The project supported the reporting of any adverse effects following immunisation from community members to the government health authorities. Vaccine hesitancy among participants was high in the early stages, but mass campaigns and vaccination of frontline health workers increased their acceptance. The major challenges reported by the informants were low budget and lower salaries of field staff, stacking of the registration process at the beginning, reluctance of participants, inadequate transportation and manpower, and inadequate baby feeding corners at vaccination centers.

CONCLUSION

The findings from our study will help policymakers from the Government, the UN, and other humanitarian agencies to adapt and better address the issue of vaccine acceptance and strengthen the vaccination programme.

Prevalence of COVID-19 vaccine acceptance among migrant and refugee groups: A systematic review and meta-analysis

Objectives

Understanding COVID-19 vaccine hesitancy among migrant and refugee groups is critical for achieving vaccine equity. Therefore, we aimed to estimate the prevalence of COVID-19 vaccine acceptance among migrant and refugee populations.

Methods

A systematic review (PROSPERO: CRD42022333337) was conducted (December 2019-July 2022) using PubMed, Scopus, Web of Science, ProQuest and Google Scholar.

Results

Nineteen studies from 12 countries were included. The pooled estimated prevalence of COVID-19 vaccine willingness among migrant and refugee groups was 70% (19 studies, 95% CI: 62.3-77.4%, I2: 99.19%, τ2: 0.03). Female and male participants did not differ significantly with each other (p = 0.64). Although no individual variable contributed statistically significantly in multivariable meta-regression analysis, the multivariable model that considered methodological quality, mean age of participants, participant group and country of origin explained 67% of variance.

Discussion

Proportions of migrant/refugee groups receiving COVID-19 vaccinations approximated those observed among general populations. Additional studies are needed to examine factors relating to vaccine willingness to identify the most significant factors that may be targeted in interventions.

COVID-19 Vaccine Acceptance and Hesitancy among Migrants, Refugees, and Foreign Workers: A Systematic Review and Meta-Analysis

Despite the effectiveness of current vaccines in reducing the spread and severity of SARS-CoV-2 infections, many people, including migrants, refugees, and foreign workers, are hesitant to be vaccinated. This systematic review and meta-analysis (SRMA) was conducted to determine the pooled prevalence estimate of the acceptance and hesitancy rates of the COVID-19 vaccine among these populations. A comprehensive search of the peer-reviewed literature indexed in PubMed, Scopus, Science Direct, and Web of Science databases was conducted. Initially, 797 potential records were identified, of which 19 articles met the inclusion criteria. A meta-analysis of proportions using data from 14 studies revealed that the overall acceptance rate of COVID vaccination among 29,152 subjects was 56.7% (95% CI: 44.9-68.5%), while the prevalence of vaccine hesitancy among 26,154 migrants reported in 12 studies was estimated to be 31.7% (95% CI: 44.9-68.5%). The acceptance rate for the COVID-19 vaccination first declined from 77.3% in 2020 to 52.9% in 2021 and then slightly increased to 56.1% in 2022. The most frequent factors influencing vaccine hesitancy were worries about vaccine efficacy and safety. Intensive vaccination campaigns should be implemented to raise vaccination awareness among migrants, which will increase the acceptance rate for the COVID-19 vaccine and result in herd immunity.

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.

Health and well-being of refugees, asylum seekers, undocumented migrants, and internally displaced persons under COVID-19: a scoping review

Objectives

The objective of this scoping review was to identify what is known about the impact of COVID-19 on the physical and mental well-being of refugees, asylum seekers, undocumented migrants, and internally displaced persons. The aim was also to identify barriers influencing access to treatment or prevention.

Methods

The search was conducted using PubMed/Medline, CINAHL, Scopus, and ScienceDirect. A mixed methods appraisal tool was used to assess methodological rigor. The study findings were synthesized using a thematic analysis approach.

Results and Discussion

This review comprised 24 studies and were conducted utilizing a mixed method approach incorporating both quantitative and qualitative methodologies. Two major themes were identified related to the impact of COVID-19 on the health and wellbeing of refugees, asylum seekers, undocumented migrants, and internally displaced persons and the key barriers influencing access to treatment or prevention of COVID-19. They often have barriers to accessing healthcare due to their legal status, language barriers, and limited resources. The pandemic has further strained already limited health resources, making it even more challenging for these populations to receive healthcare. This review reveals that refugees and asylum seekers in receiving facilities face a higher risk of COVID-19 infection than the general population due to their less favorable living conditions. The various health impacts stem from a lack of access to accurate information about the pandemic, misinformation, and the exacerbation of pre-existing mental health issues caused by heightened stress, anxiety, and uncertainty, fear of deportation among undocumented migrants, and overcrowding camps and detention facilities that increase exposure risk. Social distancing measures are difficult to implement in these settings, and inadequate sanitation, hygiene, and a lack of personal protective equipment further compound the problem. Moreover, the pandemic has had significant economic consequences for these populations. Many of them rely on informal or precarious employment, which has been disproportionately affected by the pandemic. Job losses and reduced working hours, and limited access to social protection can lead to increased poverty, and food insecurity. Children faced specific challenges, such as disruptions to education, additionally, interruptions in support services for pregnant women. Some pregnant women have avoided seeking maternity care due to fears of contracting COVID-19, resulting in increased home births and delays in accessing healthcare services. Factors that play a role in vaccination reluctance include uncertainty of undocumented migrants' inclusion in vaccination programs, furthermore, a growing vaccine hesitancy in the population; skepticism about the safety of vaccines, inadequate knowledge/education, a variety of access barriers such as language barriers, and logistical challenges including remote locations, and inaccurate information.

Conclusion

This review highlights that the physical health of refugees, asylum seekers, undocumented migrants, and internally displaced persons has been significantly impacted by various barriers to healthcare access during the pandemic. These barriers include legal and administrative challenges, such as a lack of documentation. Additionally, the shift to digital tools has introduced new obstacles, not only due to language barriers or limited technical knowledge but also because of structural barriers, such as the requirement of a bank ID that is often inaccessible to these groups. Other factors contributing to limited healthcare access include financial constraints, language barriers, and discrimination. Additionally, limited access to accurate information about health services, prevention measures, and available resources may hinder them from seeking care or following public health guidelines. Misinformation and lack of trust in healthcare systems can also contribute to a reluctance to access care or vaccination programs. There is concerning evidence regarding vaccine hesitancy that needs to be addressed to reduce any future pandemic outbreak, in addition there is a need to explore the factors that play a role in vaccination reluctance among children in these populations.

Advancing Community-Based Participatory Research During the COVID-19 Pandemic: A Methods Commentary on the Lessons Learned from Working with Community Data Collectors on a Refugee Health Disparities Study

This methods commentary focuses on lessons learned from working with community data collectors on a refugee health disparities study during the COVID-19 pandemic. While there is a strong literature base for community health workers in refugee or migrant communities, there is less known about the procedural elements, challenges, and effectiveness of using community data collectors (CDCs) in research with refugee or migrant communities. Recognizing the cultural wealth and unique strengths of local stakeholders in the refugee community, the research team employed a robust collaborative approach by partnering with CDCs to design and administer the Telehealth and COVID-19 Knowledge, Attitudes, and Practices in New York Refugee Communities Survey. The study's success was largely due to the CDC partnership. This methods commentary highlights the utility of Community-Based Participatory Research as a culturally-responsive framework well-suited to exploring health disparities as part of a broader agenda of public health communication research.

Perceptions around COVID-19 and vaccine hesitancy: A qualitative study in Kaski district, Western Nepal

Burgeoning morbidity and mortality due to COVID-19 pandemic including the peaks in outbreaks due to different variants have attracted global attention. Although the development and rolling out of vaccines have been impressive, low- and middle-income countries suffer from a double burden: (1) lack of adequate vaccines; and (2) low vaccine uptake (vaccine hesitancy). The main objective of this study was to explore perceptions around COVID-19 and vaccine hesitancy among urban and rural population in Western Nepal. A qualitative study was conducted in six urban wards of Pokhara municipality and four rural municipalities in Kaski district of Nepal. A semi-structured interview guide was used to interview participants who were selected purposively to explore the perceived burden of COVID-19 pandemic, roles, and contributions of vaccine. Nineteen interviews were conducted by telephone following a government recommendation to avoid face-to-face meetings. Audio-recorded interviews were thematically analysed after transcription and translation into English. COVID-19 is a major (public) health concern and affects people at an individual, societal and national level. People dreaded its health hazards and consequences and seemed to be compliant with public health measures such as maintaining social distance, wearing masks and maintaining hygiene. Vaccine was considered to be a major intervention to fight the pandemic, nonetheless, the rationale and benefits of vaccines were blemished by the perceived lack of the vaccine's effectiveness, duration of protection, and its potential side-events. Expedited development of vaccine was embraced with suspicion that vaccine may have incurred compromise in quality. Science and rationale behind vaccine were smeared by misinformation and clearly counteracting the misinformation were deemed critical. Providing information about vaccines through government entities (who are trusted) and respected individuals may engender trust and uptake of vaccine. Fighting off misinformation of COVID-19 is critical to curb the course of pandemic. Increased attention towards monitoring and investing in legitimacy of information and offering information through trusted sources can help improve the vaccine coverage.

Rapid Review of COVID-19 Vaccination Access and Acceptance for Global Refugee, Asylum Seeker and Undocumented Migrant Populations

Objectives: Refugees, asylum seekers, and undocumented migrants globally have been disproportionally impacted by COVID-19. Vaccination has been a major tool to reduce disease impact, yet concerns exist regarding equitable allocation and uptake. Methods: A rapid literature review was conducted based on PRISMA guidelines to determine COVID-19 vaccination acceptance rates and level of access for these population groups globally. Results: Relatively high COVID-19 vaccine acceptance levels were commonly reported in these populations, although, trust in host governments was a frequently expressed concern, especially for undocumented migrants. Outreach efforts and access to comprehensive information from a trusted source and in appropriate language were found to be major determinants of COVID-19 vaccine acceptance. COVID-19 vaccination access and policies varied considerably across host countries despite urgings by international organizations to include migrants and refugees. While most governments endorsed inclusive policies, evidence of successful program implementation was frequently lacking, creating difficulty to better tailor and implement COVID-19 outreach programs. Conclusion: This review identifies impactful improvements to be implemented to ensure equitable COVID-19 vaccinations and to reduce disease burden on refugees, asylum seekers, and undocumented migrants.

Changes in COVID-19 Vaccine Intent Among a Diverse Population of Older Adults, June 2021-February 2022

Introduction COVID-19 vaccination rates remain suboptimal in the United States. Clinicians and policymakers need to better understand how likely vaccine-hesitant individuals are to ultimately accept vaccination and what is associated with such changes. This study's aims were to 1) describe changes between vaccine intentions and actual uptake from June 2021 through February 2022, and 2) identify modifiable factors associated with vaccine uptake among those with initial hesitancy. Methods This cohort study included a stratified random sample of adults aged 65 years and older in an integrated health care system. The survey, conducted June through August 2021, elicited intent and perceptions regarding COVID-19 vaccination. Subsequent vaccine uptake through February 2022 was analyzed using electronic health records. Results Of 1195 individuals surveyed, 66% responded; 213 reported not yet having received a COVID-19 vaccine and were further analyzed. At baseline, most individuals said they would definitely not (42%) or probably not (5%) get the COVID-19 vaccine or were not sure (26%). During follow-up, 61 individuals (29%) were vaccinated, including 19% of those who initially said they would definitely not be vaccinated. Among vaccine-hesitant individuals, the rate of vaccination was highest for those who initially considered COVID-19 less dangerous than the vaccine (46%) or named short-term side effects (36%) as their most important concern. Conclusions COVID-19 vaccine intent among older adults was malleable during the pandemic's second year, even among those who initially said they would definitely not be vaccinated. Vaccine uptake could be enhanced by increasing awareness of COVID-19 risks and by addressing vaccine side effects.

Vaccine hesitancy in the refugee, immigrant, and migrant population in the United States: A systematic review and meta-analysis

Refugees, immigrants, and migrants (RIM) in the United States (US) have been identified as an underimmunized population prior to the COVID-19 pandemic. Vaccine acceptance is critical to combat the public health threat incited by COVID-19 and other vaccine-preventable disease. To better understand escalating vaccine hesitancy among US RIM, a comprehensive evaluation of the problem and solutions is necessary. In this systematic review, we included 57 studies to describe vaccination rates, barriers, and interventions addressing vaccine hesitancy over the past decade. Meta-analysis was performed among 22 studies, concluding that RIM represent an underimmunized population compared to the general US population. Narrative synthesis and qualitative methods were used to identify critical barriers, including gaps in knowledge, poor access to medical care, and heightened distrust of the medical system. Our results demonstrate the need for effective, evidence-based interventions to increase vaccination rates among diverse RIM populations.

Factors associated with reversals of COVID-19 vaccination willingness: Results from two longitudinal, national surveys in Japan 2021-2022

BACKGROUND

Research characterizing changes of heart with respect to vaccine intention is scarce, and very little research considers those who were initially vaccine willing but became hesitant. Here, we sought to assess the factors related to reversals of vaccine willingness.

METHODS

We conducted a longitudinal, national survey on vaccination intention among Japanese adults aged 20 years or older, with the first questionnaire performed in February-March 2021 (N = 30,053) and the follow-up in February 2022 (N = 19,195, response rate 63.9%). The study population comprised those who reported vaccine willingness in the first survey, with the outcome variable being development of vaccine hesitancy at follow-up. We performed a regression analysis of vaccination status using sociodemographic, health-related, psychologic/attitudinal, and information-related variables as predictors. We used the sparse group minimax concave penalty (MCP) to select the optimum group of covariates for the logistic regression.

FINDINGS

Of 11,118 (57.9%) respondents who previously expressed interest in vaccination, 10,684 (96.1%) and 434 (3.9%) were in the vaccine willing and hesitant groups, respectively. Several covariates were found to significantly predict vaccine hesitancy, including marital status, influenza vaccine history, COVID-19 infection/testing history, engagement in COVID-19 preventive measures, perceived risks/benefits of the COVID-19 vaccine, and attitudes regarding vaccination policies and norms. The use of certain information sources was also associated with vaccine hesitancy.

INTERPRETATION

Sociodemographic, health-related, psychologic/attitudinal, and information-related variables predicted the development of vaccine hesitancy among those with prior willingness. Most of these predictors were also associated with vaccination status.

Characterising reasons for reversals of COVID-19 vaccination hesitancy among Japanese people: One-year follow-up survey

BACKGROUND

Vaccine hesitancy is a global public health threat. We present unique data that characterises those who experienced reversals of COVID-19 vaccination hesitancy in Japan.

METHODS

We administered a questionnaire on vaccination intention among 30053 Japanese adults aged 20 years or older before the COVID-19 vaccination was available to the general population (first survey) and conducted a follow-up survey on vaccination status one year later in February 2022 (second survey). Those who responded in the first survey that they did not intend to be vaccinated or were unsure and then responded in the second survey that they were vaccinated or intend to be vaccinated were asked about the reasons for their change of heart. Based on previous literature and expert opinion, 31 reasons for changing vaccination intention were compiled and respondents were asked to choose which among them applied to themselves, with multiple responses possible. Based on the results of those responses, each individual was then clustered using the Uniform Manifold Approximation and Projection (UMAP) dimensionality reduction technique and Ordering Points To Identify the Clustering Structure (OPTICS) algorithm. We then identified unique characteristics among each of the sub-populations (clusters).

FINDINGS

In the second survey we received 19195 responses (response rate 63.9%), of which 8077 responded 'no' or 'not sure' in the first survey regarding their intention to be vaccinated. Of these, 5861 responded having received or intending to receive the vaccine (72.6%). We detected six and five sub-populations (clusters) among the 'no' group and 'not sure' group, respectively. The clusters were characterized by perceived benefits of vaccination, including the COVID-19 vaccine, awareness of the COVID-19 vaccination status of those close to them, recognition of the social significance of COVID-19 vaccination for the spread of infection, and dispelled concerns about short-term adverse reactions and the safety of the COVID-19 vaccine. Work and personal relationship reasons were also found to be a unique overarching reason for vaccination changes of heart only among those who did not intend to vaccinate.

INTERPRETATION

Those who changed their intention to accept COVID-19 vaccination as well as their unique characteristics as detailed in this study will be important entry points when discussing how to promote vaccination to those who are hesitant to vaccinate in the future.

Geographic, Occupational, and Sociodemographic Variations in Uptake of COVID-19 Booster Doses Among Fully Vaccinated US Adults, December 1, 2021, to January 10, 2022

IMPORTANCE

COVID-19 booster vaccine can strengthen waning immunity and widen the range of immunity against new variants.

OBJECTIVE

To describe geographic, occupational, and sociodemographic variations in uptake of COVID-19 booster doses among fully vaccinated US adults.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional survey study used data from the Household Pulse Survey conducted from December 1, 2021, to January 10, 2022. Household Pulse Survey is an online, probability-based survey conducted by the US Census Bureau and is designed to yield estimates nationally, by state, and across selected metropolitan areas.

MAIN OUTCOMES AND MEASURES

Receipt of a booster dose was defined as taking 2 or more doses of COVID-19 vaccines with the first one being the Johnson and Johnson (Janssen) vaccine, or taking 3 or more doses of any of the other COVID-19 vaccines. Weighted prevalence estimates (percentages) were computed overall and among subgroups. Adjusted prevalence ratios (APRs) were calculated in a multivariable Poisson regression model to explore correlates of receiving a booster dose among those fully vaccinated.

RESULTS

A total of 135 821 adults completed the survey. Overall, 51.0% were female and 41.5% were aged 18 to 44 years (mean [SD] age, 48.07 [17.18] years). Of fully vaccinated adults, the percentage who reported being boosted was 48.5% (state-specific range, from 39.1% in Mississippi to 66.5% in Vermont). Nationally, the proportion of boosted adults was highest among non-Hispanic Asian individuals (54.1%); those aged 65 years or older (71.4%); those with a doctoral, professional, or master's degree (68.1%); those who were married with no children in the household (61.2%); those with annual household income of $200 000 or higher (69.3%); those enrolled in Medicare (70.9%); and those working in hospitals (60.5%) or in deathcare facilities (eg, funeral homes; 60.5%). Conversely, only one-third of those who ever received a diagnosis of COVID-19, were enrolled in Medicaid, working in pharmacies, with less than a high school education, and aged 18 to 24 years old were boosted. Multivariable analysis of pooled national data revealed that compared with those who did not work outside their home, the likelihood of being boosted was higher among adults working in hospitals (APR, 1.23; 95% CI, 1.17-1.30), ambulatory health care centers (APR, 1.16; 95% CI, 1.09-1.24), and social service settings (APR, 1.08; 95% CI, 1.01-1.15), whereas lower likelihood was seen among those working in food or beverage stores (APR, 0.85; 95% CI, 0.74-0.96) and the agriculture, forestry, fishing, or hunting industries (APR, 0.83; 95% CI, 0.72-0.97).

CONCLUSIONS AND RELEVANCE

These findings suggest continuing disparities in receipt of booster vaccine doses among US adults. Targeted efforts at populations with low uptake may be needed to improve booster vaccine coverage in the US.
