What are the challenges in the vaccination of migrants in Norway from healthcare provider perspectives? A qualitative, phenomenological study

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.

Knowledge and attitudes of healthcare personnel about vaccination of migrant and refugee children and adolescents

Background

The number of migrants to Greece has increased considerably the last decade. This study assessed the knowledge and attitudes of healthcare personnel (HCP) toward vaccination of newly-arrived children and adolescents in the Aegean islands, a major port of entry of migrants and refugees to Europe.

Methods

The study was conducted from September 2020 to January 2021. All (166) HCP employed in the public health sector of the Aegean islands were invited to participate. A structured questionnaire was used to collect demographic data and data about their knowledge and attitudes toward vaccinations for migrant and refugees.

Results

A total of 120 HCP participated (72 % response rate), including 54 (45 %) physicians, 43 nurses (35.8 %), and 23 health visitors (19.2 %). Sixty-seven (55.8 %) HCP were aware of the national vaccination guidelines. Health visitors had higher rates of knowledge about the national vaccination guidelines, compared with nurses and physicians (87% versus 44,2% and 51,9%; p-value-0.001). Overall, 73 (60.8 %) HCP were aware of vaccinations during the first examination upon arrival. Primary-healthcare physicians were more likely to be aware about the time of vaccine administration compared with hospital-based physicians (74 % versus 50 %; p-value = 0.006). Out of 120 HCP, 45 % knew that vaccination guidelines apply to all newly-arrived migrant and refugees and 65 % that vaccinations are free-of-charge. Overall, 67.5 % of participants supported no serology testing before vaccination, 21.8 % were against free-of-charge vaccinations, and 55 % recommended only priority vaccinations.

Conclusions

There is a need to increase HCP' awareness and knowledge through training programs and tailored protocols focusing on vaccinations for newly-arrived migrant and refugee children and adolescents in order to promote effective vaccination of this vulnerable population.

Exploring factors that influence vaccination uptake for children with refugee backgrounds: An interpretive description study of primary healthcare providers' perspectives

BACKGROUND

Children with refugee backgrounds are at high risk of acquiring vaccine preventable diseases (VPDs) due to a complex set of factors, one being under-immunisation. In Aotearoa New Zealand (NZ), reported age-appropriate vaccination rates are suboptimal among children with refugee backgrounds.

METHODS

A qualitative interpretive description study was undertaken to explore factors associated with access and uptake of immunisations and develop strategies to improve age-appropriate vaccinations among refugee children post-resettlement in NZ. Semi-structured interviews were conducted with healthcare providers (nurses and doctors) (N = 14) across seven resettlement locations in NZ. Collected data was transcribed verbatim and thematically analysed.

RESULTS

Five themes were derived from the data that demonstrate the interrelated factors that influence vaccination uptake across the refugee caregiver, health provider and system levels. Providers discussed how caregivers' competing resettlement priorities and challenges early in the resettlement phase influenced their knowledge and access of vaccines and health services in NZ. Providers' knowledge of refugee caregivers' concerns was seen as a driver for positive change in forming therapeutic relationships with, and delivering health services to, former refugees. They discussed system level factors that influence access to and provision of immunisation services, such as resourcing, resettlement policies, system inefficiencies and missed opportunities. Emphasis was placed on communication between patients and providers to facilitate positive immunisation experiences. Overwhelming, providers displayed high motivation to improve immunisation services. Strategies were suggested to overcome identified barriers and included the provision of culturally and linguistically appropriate resources, education campaigns, reducing access barriers (e.g., after-hours clinics), and improving system efficiencies.

CONCLUSIONS

These findings highlight root factors that impact immunisation uptake and experiences among children with refugee backgrounds. To reduce the burden of VPDs, broad system level changes are required to address the barriers to vaccine uptake faced by both families of refugee backgrounds and health providers.

Access to Vaccination for Newly Arrived Migrants: Developing a General Conceptual Framework for Understanding How to Improve Vaccination Coverage in European Countries

Objectives: Access to vaccination for newly arrived migrants (NAMs) is a relevant concern that requires urgent attention in EU/EEA countries. This study aimed to develop a General Conceptual Framework (GCF) for understanding how to improve vaccination coverage for NAMs, by characterizing and critically analyzing system barriers and possible strategies to increase vaccination. Methods: A theoretical conceptualization of the GCF was hypothesized based on conceptual hubs in the immunization process. Barriers and solutions were identified through a non-systematic desktop literature review and qualitative research. The GCF guided the activities and facilitated the integration of results, thereby enriching the GCF with content. Results: The study explores the vaccination of NAMs and proposes strategies to overcome barriers in their vaccination process. It introduces a framework called GCF, which consists of five interconnected steps: entitlement, reachability, adherence, achievement, and evaluation of vaccination. The study also presents barriers and solutions identified through literature review and qualitative research, along with strategies to enhance professionals' knowledge, improve reachability, promote adherence, achieve vaccination coverage, and evaluate interventions. The study concludes by recommending strategies such as proximity, provider training, a migrant-sensitive approach, and data collection to improve vaccination outcomes for NAMs. Conclusion: Ensuring equitable access to healthcare services, including vaccination, is crucial not only from a humanitarian perspective but also for the overall public health of these countries.

Health System Barriers to Child Mandatory and Optional Vaccination among Ukrainian Migrants in Poland in the Context of MMR and HPV Vaccines-A Qualitative Study

Background Migrants' access to healthcare services is limited. This study aimed to identify health system barriers to vaccination, specifically HPV/MMR vaccination among children in Ukrainian economic migrants (UMs). Methods Between December 2021-March 2022, a qualitative study of UMs living in Poland was conducted. Six focus groups were held with 53 UMs aged 15-45; in-depth interviews with 12 healthcare workers (HCWs) were also performed. A thematic analysis was conducted based on the six WHO health system building blocks. Results HCWs described gaps in integrating migrant status in accessible healthcare data which impeded active management of vaccination procedures. UMs reported that the digitization of healthcare services, intensified during the COVID-19 pandemic, reduced their access to primary care. Inadequate health information systems caused problems with the provision of credible vaccine information in translated forms, and language difficulties, experienced by both UMs and HCWs; this was enhanced by a lack of professional interpreting services. Although most UMs reported vaccinating children according to the Polish schedule, the variations in schedules across countries caused concern among UMs and increased HCWs' uncertainty about how to interpret vaccination cards, particularly in the context of possible false certificates. UMs were affected by discrimination through HCWs. HPV was deprioritized by UMs due to misconceptions about non-mandatory vaccinations; the cost was also a barrier. Conclusions The study findings have implications for migrant vaccination delivery targeting children in Poland, and other UMs receiving countries. A concerted effort is required to improve UM's awareness of the significance of vaccinations. Barriers to healthcare access must be recognized by policymakers. Importantly, removing the cost barrier may increase the uptake of the HPV vaccine among Ukrainian migrant adolescents.

"We don't routinely check vaccination background in adults": a national qualitative study of barriers and facilitators to vaccine delivery and uptake in adult migrants through UK primary care

OBJECTIVES

Explore primary care professionals' views around barriers/facilitators to catch-up vaccination in adult migrants (foreign-born; over 18 years of age) with incomplete/uncertain vaccination status and for routine vaccines to inform development of interventions to improve vaccine uptake and coverage.

DESIGN

Qualitative interview study with purposive sampling and thematic analysis.

SETTING

UK primary care.

PARTICIPANTS

64 primary care professionals (PCPs): 48 clinical-staff including general practitioners, practice nurses and healthcare assistants; 16 administrative-staff including practice managers and receptionists (mean age 45 years; 84.4% women; 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 personal and service-delivery levels, with themes including: lack of training and knowledge of guidance among staff; unclear or incomplete vaccine records; and lack of incentivisation (including financial) and dedicated time and care pathways. Adult migrants were reported as being excluded from many vaccination initiatives, most of which focus exclusively on children. Where delivery models existed, they were diverse and fragmented, but included a combination of opportunistic and proactive programmes. PCPs noted that migrants expressed to them a range of views around vaccines, from positivity to uncertainty, to refusal, with specific nationality groups reported as more hesitant about specific vaccines, including measles, mumps and rubella (MMR).

CONCLUSIONS

WHO's new Immunization Agenda 2030 calls for greater focus to be placed on delivering vaccination across the life course, targeting underimmunised groups for catch-up vaccination at any age, and UK primary care services therefore have a key role. Vaccine uptake in adult migrants could be improved through implementing new financial incentives or inclusion of adult migrant vaccination targets in Quality Outcomes Framework, strengthening care pathways and training and working directly with local community-groups to improve understanding around the benefits of vaccination at all ages.

Access to Vaccination among Disadvantaged, Isolated and Difficult-to-Reach Communities in the WHO European Region: A Systematic Review

Vaccination has a significant impact on morbidity and mortality. High vaccination coverage rates are required to achieve herd protection against vaccine-preventable diseases. However, limited vaccine access and hesitancy among specific communities represent significant obstacles to this goal. This review provides an overview of critical factors associated with vaccination among disadvantaged groups in World Health Organisation European countries. Initial searches yielded 18,109 publications from four databases, and 104 studies from 19 out of 53 countries reporting 22 vaccine-preventable diseases were included. Nine groups representing the populations of interest were identified, and most of the studies focused on asylum seekers, refugees, migrants and deprived communities. Recall of previous vaccinations received was poor, and serology was conducted in some cases to confirm protection for those who received prior vaccinations. Vaccination coverage was lower among study populations compared to the general population or national average. Factors that influenced uptake, which presented differently at different population levels, included health service accessibility, language and vaccine literacy, including risk perception, disease severity and vaccination benefits. Strategies that could be implemented in vaccination policy and programs were also identified. Overall, interventions specific to target communities are vital to improving uptake. More innovative strategies need to be deployed to improve vaccination coverage among disadvantaged groups.
