NI Child Health in Crisis: Falling Vaccines, Rising Mental Illness and Obesity as RCPCH Demands Urgent Action
A comprehensive new report from the Royal College of Paediatrics and Child Health has found that Northern Ireland's child health indicators are deteriorating across multiple measures simultaneously, with MMR vaccination coverage falling below the 95 per cent herd immunity threshold, 45.2 per cent of 16-year-olds estimated to have a probable mental illness, and 34.7 per cent of children aged 11 to 12 classified as overweight or obese. The report, which evaluates progress across 12 key child health indicators, has prompted paediatricians to issue an urgent call for action from the NI Executive and from Westminster.
Background
The Royal College of Paediatrics and Child Health's UK State of Child Health 2026 report is the most comprehensive assessment of child health outcomes in the United Kingdom published in recent years. The Northern Ireland-focused briefing, which accompanies the UK-wide report, provides a detailed picture of how the region is performing across a range of indicators — and the picture is one of widespread deterioration. Northern Ireland, which has the youngest population of any UK region, is performing worst on several of the most critical indicators, including infant mortality, vaccination uptake, and mental health.
The deterioration in child health outcomes in Northern Ireland is not a new phenomenon — it has been building for several years, driven by a combination of factors including the legacy of political instability, chronic underinvestment in public health infrastructure, and the specific pressures created by the Covid-19 pandemic and the cost-of-living crisis. But the RCPCH report provides the most comprehensive and up-to-date picture of the scale of the problem, and its findings are more alarming than many had anticipated.
The report covers 12 key indicators: infant mortality, vaccination uptake, mental health and wellbeing, obesity, asthma, diabetes, dental health, physical activity, breastfeeding, poverty, looked-after children, and child deaths from injury. Northern Ireland performs poorly on the majority of these indicators, and the trend is downward on most of them. The RCPCH has described the findings as a "wake-up call" and has called on the NI Executive to adopt a comprehensive child health strategy as a matter of urgency.
Key Developments
The vaccination figures are among the most alarming in the report. MMR vaccination coverage has declined steadily since 2020, with only 86 per cent of children having received both required doses by age five — well below the 95 per cent threshold needed for herd immunity. Northern Ireland also reports the lowest uptake of the 6-in-1 childhood vaccine in the UK. The decline in vaccination rates reflects a combination of pandemic disruption to routine immunisation programmes and the spread of vaccine misinformation, and it creates a real risk of outbreaks of preventable diseases such as measles and whooping cough.
The mental health figures are equally alarming. The estimate that 45.2 per cent of 16-year-olds in Northern Ireland have a probable mental illness is extraordinary — it means that nearly half of all teenagers in the region are experiencing significant mental health difficulties. The reported wellbeing of 11-year-olds has reached its lowest level since 2010, reflecting the cumulative impact of the pandemic, the cost-of-living crisis, and the ongoing political instability of the Stormont institutions on the mental health of young people. Child and Adolescent Mental Health Services in Northern Ireland are wholly inadequate to meet this level of need, with waiting lists running to more than 18 months in some areas.
The obesity figures are also concerning. In the 2023-24 period, 34.7 per cent of children aged 11 to 12 were classified as overweight or obese — a figure that reflects the broader public health challenges facing Northern Ireland, including high rates of poverty, limited access to healthy food, and insufficient opportunities for physical activity. The RCPCH has called for a comprehensive strategy to address childhood obesity, including investment in school sports facilities, restrictions on the marketing of unhealthy food to children, and support for families to access healthy food.
Why It Matters
The RCPCH report is a comprehensive indictment of the state of child health in Northern Ireland, and it demands a comprehensive response. The deterioration in outcomes across multiple indicators simultaneously suggests that the problems are systemic rather than isolated, and that addressing them will require a sustained, cross-departmental effort rather than a series of targeted interventions. The report's call for a comprehensive child health strategy — one that addresses the root causes of health inequality as well as the immediate clinical needs of children — is the right response to the scale of the challenge.
The vaccination figures are particularly urgent. The decline in MMR coverage below the herd immunity threshold creates a real and immediate risk of measles outbreaks, which can be serious and even fatal for young children and for immunocompromised individuals. Restoring vaccination rates to the 95 per cent threshold should be a priority for the Department of Health and for the Public Health Agency, and it will require a sustained public information campaign as well as practical measures to make vaccination more accessible for families who have missed appointments.
The mental health figures represent perhaps the most profound challenge. A society in which nearly half of all teenagers have a probable mental illness is a society in crisis, and the current provision of CAMHS in Northern Ireland is wholly inadequate to meet that level of need. Addressing the mental health crisis will require not just investment in clinical services but a broader approach that addresses the social determinants of mental health — poverty, housing, education, and community support — and that builds resilience in young people from an early age.
Local Impact
The impact of the child health crisis is felt across Northern Ireland's five health and social care trusts. In the Belfast Trust, which covers the city and its immediate hinterland, the combination of high levels of deprivation and limited access to preventive health services creates particular challenges. In the Western Trust, which covers Derry/Londonderry and the wider north-west, the geographic isolation of many communities adds to the difficulty of delivering health services. In the Southern Trust, which covers Armagh, Newry, and the border counties, high rates of child poverty are directly correlated with poor health outcomes. In the Northern Trust, covering Antrim, Ballymena, and the north coast, and the South Eastern Trust, covering Down and the Ards Peninsula, the challenges are somewhat different but no less significant. Across all five trusts, the common thread is a health system that is under severe pressure and that lacks the resources to meet the needs of the children it serves.
What's Next
The RCPCH has called on the NI Executive to adopt its proposed roadmap for child health as a matter of urgency. The Department of Health is expected to respond to the report within the coming weeks. The Public Health Agency has indicated that it will review its vaccination outreach programmes in light of the report's findings. The Stormont Assembly is expected to debate the report when it sits later this month, with all parties likely to use the debate to press for additional investment in child health services. The ongoing budget deadlock at Stormont complicates any immediate response, as new investment in child health services requires a formal budget agreement. The Secretary of State for Northern Ireland has been urged by the RCPCH to ensure that child health is a central consideration in any budget settlement.
