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

Parental knowledge on the respiratory syncytial virus before the nirsevimab immunization program: Attitudes toward immunization in an autonomous community of Spain

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in young children and associated with most bronchiolitis- and pneumonia-related hospitalizations. A new preventive monoclonal antibody (MAb), nirsevimab, has been launched in the United States, Luxembourg, and France, and was recently approved to be given in a population-based manner throughout Spain. This study aimed to have a first pre-immunization insight into the Spanish parental knowledge about bronchiolitis, RSV, and nirsevimab immunization. Parents in Murcia with children <2 years of age up to the date of September 1, 2023, were selected to complete a questionnaire. The primary endpoint was the parental knowledge about bronchiolitis, RSV, and nirsevimab. A total of 3,217 responses were analyzed. The majority (95.8%) were aware of bronchiolitis. Meanwhile, 46.6% of the respondents knew about RSV, most of them only after the first child's birth. Information about RSV or bronchiolitis was mainly obtained from family members, with only 4.8% reporting having been informed by Health care Professionals (HCPs). Only 11.2% of respondents were aware of nirsevimab. Nonetheless, these were not entirely satisfied with the information received (score of 3.3 out of 5) and shared that HCPs should be the primary source of information. The present survey then highlights the need for better and more efficient educational strategies directed to all parents/legal guardians. It also sheds some light on the different factors that should be considered to improve awareness of RSV immunization to decrease its burden in Spain and beyond.

Vaccine Coverage at 36 Months and 7 Years by Parental Birth Country, Washington State

BACKGROUND AND OBJECTIVES

Ensuring equitable vaccination access for immigrant communities is critical for guiding efforts to redress health disparities, but vaccine coverage data are limited. We evaluated childhood vaccination coverage by parental birth country (PBC) through the linkage of Washington State Immunization Information System data and birth records.

METHODS

We conducted a retrospective cohort evaluation of children born in Washington from January 1, 2006 to November 12, 2019. We assessed up-to-date vaccination coverage status for measles, mumps, and rubella (MMR), diphtheria, tetanus, and pertussis (DTaP), and poliovirus vaccines at ages 36 months and 7 years. Children with ≥1 parent(s) born in selected non-US countries were compared with children with 2 US-born parents, using Poisson regression models to provide prevalence ratios.

RESULTS

We identified 902 909 eligible children, of which 24% had ≥1 non-US-born parent(s). Vaccination coverage at 36 months by PBC ranged from 41.0% to 93.2% for ≥1 MMR doses and ≥3 poliovirus doses and 32.6% to 86.4% for ≥4 DTaP doses. Compared with children of US-born parents, the proportion of children up to date for all 3 vaccines was 3% to 16% higher among children of Filipino-, Indian-, and Mexican-born parents and 33% to 56% lower among children of Moldovan-, Russian-, and Ukrainian-born parents. Within-PBC coverage patterns were similar for all vaccines with some exceptions. Similar PBC-level differences were observed at 7 years of age.

CONCLUSIONS

The linkage of public health data improved the characterization of community-level childhood immunization outcomes. The findings provide actionable information to understand community-level vaccination determinants and support interventions to enhance vaccine coverage.

Impact of COVID-19 on the Health of Migrant Children in the United States: From Policy to Practice

In this article, the authors provide an overview how the COVID-19 pandemic impacted the health and wellbeing of migrant children in conflict zones, in transit and post-settlement in the United States. In particular, the authors explore how policies implemented during the pandemic directly and indirectly affected migrant children and led to widening disparities in the aftermath of the pandemic. Given these circumstances, the authors provide recommendations for child health care providers caring for migrant children to mitigate and bolster resilience and health.

Correlates of COVID-19 vaccine uptake among the forcibly displaced: evidence from Libya

BACKGROUND

Vaccine hesitancy and refusal can hinder the control of infectious diseases such as coronavirus disease 2019 (COVID-19). Although forcibly displaced individuals are at high risk of contracting COVID-19, evidence shows that they are less likely to accept the COVID-19 vaccine. Given their predicament, the factors influencing vaccine uptake in the general population might differ vastly from those in displaced populations. Given the limited evidence on vaccine uptake from humanitarian settings, the current study examined the determinants of COVID-19 vaccine uptake among the forcibly displaced in Libya.

METHODS

Data were extracted from the World Bank/United Nations High Commissioner for Refugees (UNHCR) microdata repository. Data were collected between April and July 2021 after the rollout of the first dose of the COVID-19 vaccine in Libya. Percentages, means, and standard deviations were used to quantify the distribution of the sample population. Logistic regression models were employed to identify factors influencing COVID-19 vaccine uptake.

RESULTS

Odds ratios (ORs) with p values are used to present the regression analysis results. The study revealed that people unaffected by COVID-19 were less likely (OR = .71, 95%CI = 0.67-0.89) to accept the vaccine. Similarly, individuals with access to free COVID-19 vaccines were more likely to be vaccinated than those without free vaccines (OR = 38, 95%CI = 0.19-0.28). Finally, the results indicated that individuals were six times more likely to be vaccinated at mass vaccination sites ((OR = 6.31, 95%CI = 5.46- 7.94) and 1.92 times more likely to be vaccinated at local health centers (OR = 1.92, 95%CI = 0.1.72-3.11) than they were at hospitals and distant health facilities.

CONCLUSION

Implementing comprehensive mass vaccination venues, public education initiatives, and awareness campaigns regarding the importance of vaccination can decrease vaccine hesitancy among the forcibly displaced.

Driving delivery and uptake of catch-up vaccination among adolescent and adult migrants in UK general practice: a mixed methods pilot study

BACKGROUND

Migrants in the UK and Europe face vulnerability to vaccine-preventable diseases (VPDs) due to missed childhood vaccines and doses and marginalisation from health systems. Ensuring migrants receive catch-up vaccinations, including MMR, Td/IPV, MenACWY, and HPV, is essential to align them with UK and European vaccination schedules and ultimately reduce morbidity and mortality. However, recent evidence highlights poor awareness and implementation of catch-up vaccination guidelines by UK primary care staff, requiring novel approaches to strengthen the primary care pathway.

METHODS

The 'Vacc on Track' study (May 2021-September 2022) aimed to measure under-vaccination rates among migrants in UK primary care and establish new referral pathways for catch-up vaccination. Participants included migrants aged 16 or older, born outside of Western Europe, North America, Australia, or New Zealand, in two London boroughs. Quantitative data on vaccination history, referral, uptake, and sociodemographic factors were collected, with practice nurses prompted to deliver catch-up vaccinations following UK guidelines. Focus group discussions and in-depth interviews with staff and migrants explored views on delivering catch-up vaccination, including barriers, facilitators, and opportunities. Data were analysed using STATA12 and NVivo 12.

RESULTS

Results from 57 migrants presenting to study sites from 18 countries (mean age 41 [SD 7.2] years; 62% female; mean 11.3 [SD 9.1] years in UK) over a minimum of 6 months of follow-up revealed significant catch-up vaccination needs, particularly for MMR (49 [86%] required catch-up vaccination) and Td/IPV (50 [88%]). Fifty-three (93%) participants were referred for any catch-up vaccination, but completion of courses was low (6 [12%] for Td/IPV and 33 [64%] for MMR), suggesting individual and systemic barriers. Qualitative in-depth interviews (n = 39) with adult migrants highlighted the lack of systems currently in place in the UK to offer catch-up vaccination to migrants on arrival and the need for health-care provider skills and knowledge of catch-up vaccination to be improved. Focus group discussions and interviews with practice staff (n = 32) identified limited appointment/follow-up time, staff knowledge gaps, inadequate engagement routes, and low incentivisation as challenges that will need to be addressed. However, they underscored the potential of staff champions, trust-building mechanisms, and community-based approaches to strengthen catch-up vaccination uptake among migrants.

CONCLUSIONS

Given the significant catch-up vaccination needs of migrants in our sample, and the current barriers to driving uptake identified, our findings suggest it will be important to explore this public health issue further, potentially through a larger study or trial. Strengthening existing pathways, staff capacity and knowledge in primary care, alongside implementing new strategies centred on cultural competence and building trust with migrant communities will be important focus areas.

Vaccine Hesitancy among Immigrants: A Narrative Review of Challenges, Opportunities, and Lessons Learned

(1) Background: Vaccination reluctance is a major worldwide public health concern as it poses threats of disease outbreaks and strains on healthcare systems. While some studies have examined vaccine uptake within specific countries, few provide an overview of the barriers and trends among migrant groups. To fill this knowledge gap, this narrative review analyzes immunization patterns and vaccine hesitancy among immigrant populations. (2) Methods: Four researchers independently evaluated the quality and bias risk of the 18 identified articles using validated critical appraisal tools. (3) Results: Most studies focused on vaccine hesitancy among migrants in the United States and Canada, with a higher COVID-19 vaccine reluctance than native-born residents. Contributing factors to this hesitancy include demographics, cultural views, obstacles to healthcare access, financial hardship, and distrust in health policies. Additionally, immigrants in North America and Europe face unfair vaccine challenges due to misinformation, safety concerns, personal perspectives, language barriers, immigration status, and restricted healthcare access. (4) Conclusions: Tailored vaccine education programs and outreach campaigns sensitive to immigrants' diversity should be developed to address this issue. It is also important to investigate community-specific obstacles and assess the long-term sustainability of current efforts to promote vaccination among marginalized migrant groups. Further research into global immunization disparities among immigrant populations is crucial.

Diverse Parents Decision-Making to Vaccinate Their Child under Five Attending Childcare Programs

Background: On 18 June 2022, Moderna and Pfizer-BioNTech COVID-19 vaccines were authorized under an Emergency Use Authorization by the United States Food and Drug Administration to prevent severe coronavirus disease in children six months to four years of age. Despite approval of the COVID-19 vaccinations for young children, there remain ongoing challenges reaching widespread coverage due to parental decision-making. Parental decision-making plays a pivotal, yet understudied, role governing vaccine adoption among this priority demographic. Methods: This cross-sectional analysis examined COVID-19 vaccine intentions for 320 predominately Hispanic parents of two to five-year-olds attending Miami-Dade County childcare programs in Florida USA, several months following the June 2022 emergency authorization. Parent's self-reported survey data encompassed vaccine choices and rationales, social determinants of health, and parent immigrant status. Data analyses illustrate the associations between parent decision-making and these variables. Regression modeling and tests of independence identified predicting factors for parental vaccine decision-making. Results: Only 25% of parents intended to vaccinate their young child, while 34% resisted and 41% felt unsure, despite 70% personal vaccination rates. Household income under $25,000, identifying as a migrant, or testing COVID-19-positive significantly predicted unsure decision-making. The majority of hesitant groups expressed concerns around side effects (20%), safety (2.9%), and sufficiency of vaccine knowledge (3.3%). Conclusions: In this sample, the predominance of parents were unsure and resistant rather than accepting of having their child vaccinated despite emergency approval of the pediatric vaccine. Associations and predictive factors are examined.

"You Don't Know If It's the Truth or a Lie": Exploring Human Papillomavirus (HPV) Vaccine Hesitancy among Communities with Low HPV Vaccine Uptake in Northern California

BACKGROUND

Vaccine hesitancy, delaying or refusing to vaccinate despite the availability of vaccines, impedes the progress of achieving optimal HPV vaccine coverage. Little is known about the sources of human papillomavirus (HPV) vaccine hesitancy among racially/ethnically and geographically diverse communities. The purpose of this paper is to explore HPV vaccine hesitancy among rural, Slavic, and Latino communities that reside in counties with low HPV vaccine uptake rates.

METHODS

Key informant interviews and focus groups were conducted with rural, Slavic, and Latino communities that reside within counties in California that have low HPV vaccine up to date rates (16-25%). Qualitative data were transcribed verbatim and analyzed using inductive and deductive thematic analysis.

RESULTS

A total of seven focus groups and 14 key informant interviews were conducted with 39 individuals from seven California counties. Salient themes that contributed to HPV vaccine hesitancy included the following: social media and the anti-vaccination movement; a strong belief in acquiring immunity naturally; prior vaccine experiences; and vaccine timing concerns. Participants suggested the provision of culturally appropriate, in-language, in-person easy to understand HPV vaccine education to mitigate HPV vaccine hesitancy.

CONCLUSIONS

Our findings can inform future interventions to increase HPV vaccine uptake among hesitant communities.

Addressing COVID-19 Vaccine Hesitancy and Uptake Among African Immigrants: Lessons from a Community-Based Outreach Program

In 2021, the African Cultural Alliance of North America (ACANA) implemented a community-based vaccine education and outreach program to decrease hesitancy and increase COVID-19 vaccine uptake among African immigrants in Philadelphia. The program had three components: (1) tailored messaging on the benefits of vaccines by trusted community health navigators in familiar languages/dialects, (2) use of educational/tabling events, and (3) establishment of a vaccine clinic in community settings. Using secondary data analysis, in-depth interviews, focus group discussions and a self-administered survey, we explored (i) the impact and effectiveness of the outreach program and extent of vaccine uptake, (ii) African immigrants' beliefs about the COVID-19 pandemic and the vaccine, and (iii) barriers and facilitators of vaccine knowledge, uptake, and hesitancy. Our analysis showed that ACANA's outreach program was effective in addressing several cultural, logistic, and systematic barriers to vaccine uptake. The program distributed 2000 educational/informational flyers, reached 3000 community members via social media campaigns, and an additional 2320 through other person-to-person outreach events. The program was effective and resulted in the vaccination of 1265 community members over the course of the outreach. The impact of this outreach underscores the critical role of community-based organizations in addressing COVID-19 vaccine hesitancy and increasing vaccine uptake in underserved and minority communities. The paper concludes with suggestions and recommendations for using community-based outreach programs to increase COVID-19 vaccine uptake and decrease hesitancy.

Social determinants of health and vaccine uptake in pregnancy: Disparities in a diverse, predominately foreign-born population

OBJECTIVE

To identify discrepancies in influenza, Tdap, and COVID-19 vaccine uptake and offer rates among pregnant individuals across various social determinants of health including race, ethnicity, foreign-born status, education level, and health insurance coverage, highlighting potential interventions to improve vaccine uptake in pregnancy.

METHODS

An IRB-approved cross-sectional survey was conducted on the postpartum floor of a large urban hospital in South Florida. Between July to September 2021, 359 participants consented and answered questions on their demographics, social background, and influenza, Tdap, and COVID-19 vaccine history.

RESULTS

Most participants identified as White (67.7 %), Hispanic (67.4 %), and foreign-born (68.5 %) with an average age of 29.7 ± 6 years. There was a significant difference in mean vaccine between White (1.3) and Black individuals (0.9, p = 0.002). Mean uptake was significantly higher in foreign-born individuals (1.3) compared to US-born (0.9, p < 0.001). Mean uptake was significantly higher for those with graduate (1.7) and college (1.4) degrees compared to those with a high school degree (1.0) or less than high school (1.0, p < 0.0001).

CONCLUSION

Significant differences in the uptake and offer rates of influenza, Tdap, and COVID-19 vaccines were observed across a variety of social determinants including educational attainment, employment, insurance, and median income of the zip code of primary residence.

On the path to recovery: traumatic stress research during the COVID-19 pandemic 2021-2023

This Special Issue of the European Journal of Psychotraumatology (EJPT) presents 51 articles published between 2021 and 2023 and follows the Special Issue on pandemic-related traumatic stress research published in 2021 (O'Donnell, M. L., & Greene, T. [2021]. Understanding the mental health impacts of COVID-19 through a trauma lens. European Journal of Psychotraumatology, 12(1), 1982502). Research on traumatic stress during the pandemic has cast the spotlight on vulnerable populations and groups, notably front-line healthcare workers; people faced with major losses including the deaths of loved ones; those who personally survived debilitating and often life-threatening viral infection; and students who were isolated and experienced profound delays in their education, relationships, and emerging independence. The papers in this collection underscore the associations between COVID-19 related stressors and a plethora of adverse mental health sequelae, including posttraumatic stress reactions, and draw attention to the ubiquity of grief and moral injury and their wide-ranging and detrimental impact. Currently, there is a paucity of evidence on interventions to enhance resources, self-efficacy, and hope for affected groups and individuals through societal, organisational, and healthcare systems; however early research on the prevention of COVID-related traumatic stress disorders provides a basis for both hope and preparedness for the future.

The Challenges of Vaccine Trial Participation among Underserved and Hard-to-Reach Communities: An Internal Expert Consultation of the VACCELERATE Consortium

Underserved and hard-to-reach population groups are under-represented in vaccine trials. Thus, we aimed to identify the challenges of vaccine trial participation of these groups in member countries of the VACCELERATE network. Seventeen National Coordinators (NC), each representing their respective country (15 European countries, Israel, and Turkey), completed an online survey. From 15 eligible groups, those that were more frequently declared underserved/hard-to-reach in vaccine research were ethnic minorities (76.5%), persons experiencing homelessness (70.6%), illegal workers and refugees (64.7%, each). When prioritization for education on vaccine trials was considered, ethnic groups, migrants, and immigrants (5/17, 29.4%) were the groups most frequently identified by the NC as top targets. The most prominent barriers in vaccine trial participation affecting all groups were low levels of health literacy, reluctance to participate in trials due to engagement level, and low levels of trust in vaccines/vaccinations. This study highlighted population groups considered underserved/hard-to-reach in countries contained within the European region, and the respective barriers these groups face when participating in clinical studies. Our findings aid with the design of tailored interventions (within-and across-countries of the European region) and with the development of strategies to overcome major barriers in phase 2 and phase 3 vaccine trial participation.

Bringing COVID-19 vaccine to medically underserved populations utilizing a community-guided mobile vaccine program

Between March 23, 2021, and December 31, 2022, the Mobile Vaccine Program (MVP) vaccinated 5044 individuals from medically-underserved communities in Middle Tennessee identified through and guided by a collaboration of local community agencies. The primary objective of the MVP was to vaccinate individuals for COVID-19 who had barriers to traditional mass vaccine strategies through community-guided strategies and partnerships. Three strategies were developed and implemented with community partners and their affiliated community health workers (CHWs). The strategies included pop-up vaccination clinics at community partner events, CHW-guided door-to-door in-home vaccination, and community partner-initiated homebound referrals for vaccination.

Predictors of COVID-19 Vaccine Uptake and Reasons for Vaccine Hesitancy Among New York State Refugees

PURPOSE

Resettled refugees in the U.S. face a disproportionately high risk of COVID-19 exposure, infection, and death. This study examines COVID-19 vaccination status among adult participants and their minor children, reasons for vaccine hesitancy, and predictors of vaccine uptake, as well as sources of COVID-19 news and information and trust in those sources.

METHOD

The data in this study were drawn from the Telehealth and COVID-19 Knowledge, Attitudes, and Practices in New York Refugee Communities Survey (N = 353), conducted March-May, 2022.

RESULTS

The multivariate results indicate that in this sample of resettled refugees, those who reported higher levels of educational attainment, were from Afghanistan, and those who had fewer concerns about the vaccine were more likely to accept vaccination. The participants in this study identified local health workers, clinics, and community organizations - places where social workers are present - as both the largest source of nonsocial media COVID-19 news and information and the most trusted source of COVID-19 news and information.

DISCUSSION

The implications from this study provide social workers with an understanding of the social and behavioral factors impacting vaccine uptake in refugee communities.

CONCLUSION

According to the NASW Code of Ethics, social workers must challenge inequalities that persist against marginalized groups, such as racial and ethnic health disparities. Social work practitioners can play an essential role in decreasing unjust health disparities by providing accurate, culturally appropriate information on public health concerns such as COVID-19 to their refugee clients and within interprofessional collaboration.

Non-vaccination Against COVID-19 Among Venezuelan Refugees and Migrants Adults in Peru: A Cross-sectional Study, 2022

OBJECTIVES

The purpose of this study was to determine factors associated with non-vaccination against coronavirus disease 2019 (COVID-19) among the Venezuelan immigrant population residing in Peru.

METHODS

A cross-sectional study was conducted using data obtained from the Second Survey of the Venezuelan Population Residing in Peru in 2022. The dependent variable was vaccination status against COVID-19. The independent variables included socio-demographic, economic, and migratory characteristics of the included population. Crude and adjusted generalized linear Poisson-family models were used to calculate prevalence ratios with 95% confidence intervals (CIs).

RESULTS

A total of 7739 Venezuelan migrants aged 18 years or older were included. The proportion of non-vaccination against COVID-19 was 5.7%. Regarding associated factors, unemployment (adjusted prevalence ratio [aPR], 1.31; 95% CI, 1.04 to 1.65) was linked to an increased likelihood of not being vaccinated against COVID-19. In contrast, women (aPR, 0.76; 95% CI, 0.61 to 0.95), possessing a migration permit (aPR, 0.41; 95% CI, 0.31 to 0.54), and having health insurance (aPR, 0.47; 95% CI, 0.27 to 0.81) were associated with a decreased likelihood of being unvaccinated.

CONCLUSIONS

The primary governmental and non-governmental institutions responsible for supporting and protecting the Venezuelan migrant and refugee population should improve vaccination access by issuing migration permits and providing health insurance.
