Study Reveals Critical Gaps in Catch-Up Vaccinations Among UK Migrants

In our study published in the journal BMC Medicine, we report significant vulnerabilities to infectious diseases among UK migrants due to under-vaccination for diseases preventable through routine immunisations - such as measles, mumps, rubella, and polio. Our mixed-methods study, conducted between May 2021 and September 2022 across several London-based general practices, sheds light on the urgent need for improved healthcare strategies that ensure migrants receive necessary catch-up vaccinations.

Background

Migrants in the UK and Europe are often at increased risk of vaccine-preventable diseases (VPDs) due to incomplete childhood vaccinations and systemic marginalisation from health services. The COVID-19 pandemic further exacerbated these disparities, highlighting the critical gaps in vaccination coverage among adult and adolescent migrants. The study aimed to quantify these vaccination gaps and explore new strategies to improve vaccination uptake through better integration into primary care systems.

Study Insights

The "Vacc on Track" study involved 57 migrants from 18 countries, revealing a troubling landscape of under-vaccination:

  • 86% of the participants needed catch-up vaccinations for MMR.
  • 88% required catch-up for tetanus, diphtheria, and polio (Td/IPV).
  • Despite high referrals for catch-up vaccinations (93%), completion rates were dismally low, with only 12% completing the Td/IPV series and 64% completing the MMR.

Barriers and Facilitators

We identified numerous barriers to effective vaccination, including:

  • Lack of systematic approaches to catch-up vaccination upon migrants' arrival.
  • Primary care staff's limited awareness and implementation of vaccination guidelines.
  • Structural challenges such as limited appointment availability and follow-up.

Conversely, potential facilitators highlighted the importance of staff champions and community-based approaches to improve vaccination uptake. These insights suggest that primary care can play a pivotal role in reducing health inequalities by adopting more culturally competent and accessible vaccination strategies.

Conclusion

The study underscores a pressing public health issue: the need to better integrate catch-up vaccinations within primary care to protect vulnerable populations against VPDs. By strengthening existing pathways and enhancing staff training and resources, healthcare systems can make significant strides toward ensuring that all community members, regardless of their origin, are protected against preventable diseases.

Moving Forward

our findings emphasise the need for further research and larger trials to refine and implement effective strategies that ensure equitable healthcare access. As the UK continues to navigate the challenges posed by migration and health disparities, such studies are essential for informing policy and practice, aiming for a healthier, more inclusive society. This research not only highlights the gaps but also charts a course for future action, aiming to transform insights into impactful health interventions.

What is the difference between primordial prevention and primary prevention?

Primordial prevention and primary prevention are both crucial strategies for promoting health, but they operate at different levels. Primordial prevention aims to address the root causes of health problems and improve the wider determinants of health. It focuses on preventing the emergence of risk factors in the first place by tackling the underlying social, economic, and environmental determinants of health. This involves broad, population-wide interventions such as: Policies that promote healthy food choices: Think about initiatives like taxing sugary drinks to discourage unhealthy consumption, or providing subsidies for fruits and vegetables to make them more accessible. Urban planning that prioritises well-being: This could include creating walkable neighborhoods with safe cycling routes, ensuring access to green spaces for recreation and relaxation, and designing communities that foster social connections. Social programs that address inequality: Initiatives aimed at reducing pov...

UK Covid-19 Inquiry - The Importance of a Strong Primary Healthcare System

In my witness statement for Module 10 of the UK Covid-19 Inquiry, I discuss the pandemic's impact through from the perspectives of  primary care and public health, drawing on my extensive experience as a senior academic at Imperial College London and as a practising GP and NHS Public Health Specialist.  I emphasise that the pandemic disproportionately affected people who were clinically vulnerable, the disabled, ethnic minority communities and those living in deprived areas. The pandemic highlighted how structural inequalities, multigenerational housing, and employment in high-risk frontline roles exacerbated health disparities.  My statement also critiques the weakening of public health infrastructure - particularly for the control of infectious diseases - and the lack of integrated health data systems to identify at-risk groups such as the clinically vulnerable. I also advocated for a more robust preventive healthcare model that prioritises community-based primary care ...

Relevance Over Recall: Rethinking How AI Uses Clinical Data

Our article in the Journal of the Royal Society of Medicine argues that safe and effective AI in healthcare must incorporate mechanisms that emulate human judgement - down-weighting old, inaccurate or superseded information and prioritising what is recent, clinically relevant and reaffirmed - so that AI supports, rather than disrupts, high-quality patient care.  Clinicians constantly revise, reinterpret and filter past information so that only what is relevant, accurate and timely shapes present-day management decisions; medical records function as dynamic “working tools” rather than fixed archives. By contrast, many AI systems lack this capacity for selective forgetting and often treat all historical data as equally meaningful.  This can lead to outdated or low-confidence diagnoses being repeatedly resurfaced, persistent labels influencing clinical expectations, and irrelevant, long-resolved events cluttering summaries and decision-support outputs. Such indiscriminate recall...
