Exploring barriers to vaccine delivery in adult migrants: a qualitative study in primary care

Background

The COVID-19 pandemic has highlighted shortfalls in the delivery of vaccine programmes to older migrant groups. Guidelines exist, however, little is known around care pathways and engagement of these older cohorts in routine vaccinations in primary care, including catch-up programmes. We explored the views of primary care professionals around barriers and facilitators to catch-up vaccination in adult migrants (defined as foreign born; 18+ years) with incomplete or uncertain vaccination status.

Methods

We did a qualitative interview study with purposive sampling and thematic analysis in UK primary care (50 practices included nationally; 1 hour qualitative interviews) with 64 primary care professionals (PCPs): 48 clinical staff including GPs, Practice Nurses and healthcare assistants (HCAs); 16 administrative staff including practice managers and receptionists (mean age 45 years; 84.4% female; a range of ethnicities).

Results

Participants highlighted direct and indirect barriers to catch-up vaccines in adult migrants who may have missed vaccines as children, missed boosters, and not be aligned with the UK's vaccine schedule, from both a personal and service-delivery level, with themes including: lack of training and knowledge of guidance around catch-up vaccination among staff; unclear or incomplete vaccine records; and lack of incentivization (including financial reimbursement) and dedicated time and care pathways. Adult migrants were reported as being excluded from many vaccination initiatives, most of which focus exclusively on children. PCPs noted that migrants expressed to them a range of views around vaccines, from positivity to uncertainty, to refusal.

Conclusions

Vaccine uptake in adult migrants could be improved through implementing new financial incentives, strengthening care pathways and training, and working directly with local community groups to improve understanding around the benefits of vaccination at all ages.

Strategies to increase catch-up vaccination among migrants: a qualitative study and rapid review

Background

WHO’s Immunization Agenda 2030 has placed renewed focus on catch-up vaccination across the life course to meet global targets for reduction in vaccine-preventable diseases through increased vaccine coverage, including among migrant groups who may require catch-up vaccination to align them with host country vaccination schedules.

Methods

We did a global rapid review (01/2010 to 04/2022) to explore drivers of vaccine hesitancy among migrants followed by an in-depth qualitative study (semi-structured, telephone interviews) among recently arrived adult migrants (foreign-born, >18 years old, residing in the UK < 10 years). Interviews explored views on routine vaccination including accessibility, confidence and awareness. Data were analysed iteratively using thematic analysis.

Results

63 papers were included in the rapid review, including data from 22 countries/regions. Multiple factors driving under-immunisation and hesitancy in migrants were reported, including language barriers, low health literacy, social exclusion, low cultural competency and accessibility in healthcare systems. Our qualitative study recruited 40 migrants (mean age: 36.7 years; 62.5% female) resident in the UK (6 refugees, 19 asylum-seekers, 8 undocumented, 7 labour migrants). Major barriers to catch-up vaccination included a lack of provider recommendation and low awareness, with vaccination viewed as only relevant to children. Hesitancy around specific vaccines, such as MMR, was often influenced by misinformation. Participants suggested that novel strategies such as walk-in or mobile access points, consistent provider recommendations, and translation of information into relevant languages, may enhance accessibility and uptake of routine vaccinations.

Conclusions

Targeted and tailored information campaigns, versatile and proactive access pathways and education for healthcare staff on cultural competency will be needed to ensure uptake of catch-up vaccination among marginalised migrant groups.

Key messages

• Newly arrived adult migrants face barriers to catch-up vaccination in host countries, which may hinder immunisation coverage and increase the risk of vaccine-preventable disease outbreaks.

• Health systems must develop novel mechanisms to proactively offer culturally competent and accessible catch-up vaccination services to adult migrants on and after arrival.

Co-developing a tailored vaccination intervention with Congolese migrants: a participatory study

Background

Disparities in vaccination uptake among migrant populations are well documented. WHO and ECDC have sought renewed focus on participatory research that engages migrants in co-producing tailored initiatives to address vaccination inequities and increase coverage.

Methods

This community-based participatory research study aims to engage Congolese migrants in co-developing a tailored approach to increase vaccine uptake. Phase 1 used poster walls and in-depth interviews with Congolese migrants (n = 32) to explore COVID-19 vaccination beliefs, experiences, and preferred information sources and communication methods, analysed iteratively and thematically in NVivo.

Preliminary results

Institutional distrust has shaped this population’s interpretation of the pandemic response and enabled vaccine misinformation and conspiracy theories to take hold. We found complex information networks and preference for Francophone, African and social media. Limited English proficiency and preference for the oral tradition restricted engagement with official public health messaging. Suspicion of government motives, low knowledge, and culturally specific perceptions about vaccination contributed to belief that breakthrough infections and need for COVID-19 boosters imply the vaccine is not effective. The population felt coerced by vaccination reminders and mandates, and were resultantly more hesitant to accept COVID-19 vaccination.

Conclusions

The population’s specific characteristics suggest that existing and trusted interpersonal networks and oral communication in first languages should be harnessed to spread credible information and encourage vaccine uptake, and mandate policies are unlikely to be effective. Training local role models to facilitate vaccination dialogues and myth-bust may be effective at changing behaviour. The next phases will gather more information from key stakeholders and engage migrants in workshops to co-design insight-driven, tailored interventions.

Key messages

• Global policy-setting organisations have called urgently for participatory research that engages migrants in the co-production of tailored initiatives to address vaccination inequalities.

• Populations with strong interpersonal networks and low trust in public institutions may be receptive to tailored, community-centred dialogue approaches using local messengers and role models.

A community-based participatory approach to engaging Congolese migrants in intervention co-design

Issue

The World Health Organization has called for tailored, community-based interventions to address disparities in vaccination uptake affecting migrant and minoritised populations, however few exist. This study directly responds to global calls for community-centred and participatory approaches to engaging migrants in routine and COVID-19 vaccination.

Problem description

Black and African migrants are known to be at risk of under-immunisation and have lower COVID-19 vaccine uptake rates in high-income countries. This UK study will use community-based participatory approaches to engage Congolese migrants in co-developing a tailored intervention to increase vaccine uptake. A community-academic coalition will lead the study. Community members will be trained as peer researchers and financially compensated. The final output will be an intervention strategy tailored to and embedded within the Congolese migrant community.

Preliminary results

The coalition held 20 hours of planning meetings and peer researcher training in 2021 and co-developed a phased study involving 1) community days with poster walls and qualitative in-depth interviews with Congolese migrants, 2) interviews and workshops with local stakeholders, and 3) co-design workshops with Congolese migrants. Following outreach and pre-engagement, approximately 80 migrants attended the community days, with more than 50 interviews and 100% left positive feedback (including: felt valued, welcomed, Congolese language recognised).

Lessons

Community-academic partnerships are resource-intensive but can be an effective means to build and maintain trust required to deliver a community-based research study. Academic partners should support community partners in understanding the research process to help manage expectations and provide financial compensation for their time and effort. This study offers an innovative engagement model and study design that can be adapted to other underserved populations.

Key messages

• Global policy-setting organisations have called urgently for participatory research that engages migrants in the co-production of tailored initiatives to address vaccination inequalities.

• This study uses a novel, theory-driven, participatory approach to engage with and identify barriers to vaccination in Congolese migrants and co-design a tailored strategy to increase uptake.

Digital screening tool (Health Catch-UP!) to promote multi-disease screening in migrants

Background

The ECDC has called for innovative strategies to deliver multi-disease screening (TB, LTBI, HIV, hepatitis B/C, Chagas, Strongyloidiasis and schistosomiasis) and catch-up vaccination (MMR, DTP) to adult migrants within the primary care context. We did a UK i qualitative study to explore current practice and seek views on a novel integrated digital tool to support delivery of screening recommendations for migrants https://emishealth.vids.io/videos/a49ad1bb1a18e4c72c/health-catch-up-with-requested-edits-mp4).

Methods

Phase 1 was conducted via telephone with clinical primary care practitioners (PCPs) (phase 1) and informed data collection and analysis for phase 2 with administrative staff. Data were analysed iteratively, informed by thematic analysis (Ethics no.20/HRA/1674).

Results

64 participants were recruited in Phase 1 (25 general practitioners [GPs], 15 nurses, 7 healthcare assistants, 1 pharmacist); Phase 2 comprised administrative staff (11 Practice-Managers, 5 receptionists). There was lack of consistency in delivery of screening and vaccination. Most GP practices adopted a practice-specific approach, or had no system in place; screening only for HIV and hepatitis B/C. Barriers to screening were perceived lack of knowledge/training and limited financial resources. Facilitators included having an infectious disease/migrant-health champion, incentivisation, and clear protocols. Participants responded positively to the integrated Health Catch-UP! tool, confirming that it would increase screening and vaccination, reduce missed opportunities for preventative healthcare, and raise awareness of migrant health.

Conclusions

Infectious disease screening and catch-up vaccination is not currently delivered well in primary care in high-migrant receiving European countries. Innovative digital tools like Health Catch-UP! could aid clinical decision-making and facilitating improved health outcomes for migrants. Further work is needed to evaluate this intervention.

Key messages

Infectious disease screening and catch-up vaccination is not currently delivered well in primary care in high-migrant receiving European countries. Innovative digital tools could aid clinical decision-making and facilitating improved health outcomes for migrants.
