WHO Raises Alarm Over Immunisation Gaps as Millions of Nigerian Children Face Preventable Diseases

The World Health Organization (WHO) has raised concerns over gaps in childhood immunisation in Nigeria, warning that children who miss routine vaccinations remain vulnerable to preventable diseases, including measles and polio.The warning highlights the urgent need to strengthen routine immunisation services, improve access to healthcare and ensure that children across the country receive life-saving vaccines.According to a report by Premium Times, the WHO called for increased domestic healthcare financing, stronger disease surveillance and improved preparedness for public health emergencies during its Health Diplomacy Dialogue in Abuja.Millions of Children Remain at RiskChildhood immunisation remains one of the most effective ways to protect children against serious infectious diseases. However, barriers to accessing healthcare continue to prevent some Nigerian children from receiving their recommended vaccines.In April 2026, UNICEF warned that approximately 2.2 million Nigerian children had never received a routine vaccine. These children, commonly referred to as zero-dose children, face an increased risk of contracting vaccine-preventable diseases.The situation underscores the need for sustained efforts to reach underserved communities, particularly families living in remote areas with limited access to healthcare facilities.Diseases such as measles, polio, tuberculosis, whooping cough and diphtheria can cause severe complications, disability or death if children are not adequately protected.Barriers to Routine ImmunisationSeveral factors contribute to gaps in childhood vaccination across Nigeria.Limited access to healthcare facilities remains a challenge for families in rural communities, where long distances and transportation costs can discourage regular clinic visits.Financial difficulties, inadequate healthcare infrastructure and shortages of health workers can also affect the delivery of routine immunisation services.In addition, misinformation and misconceptions about vaccines may discourage some parents and caregivers from vaccinating their children.Health authorities continue to emphasise the importance of providing accurate information and making vaccination services accessible to every community.Government and Health Partners Intensify EffortsNigeria has continued to work with international health organisations, state governments and community leaders to improve immunisation coverage.Interventions include identifying children who have missed vaccinations, strengthening primary healthcare facilities and conducting community outreach programmes to reach underserved populations.The World Health Organization has also highlighted efforts to reach zero-dose children in Edo State, demonstrating the importance of community engagement and targeted vaccination services.These initiatives aim to ensure that children who have previously missed routine vaccinations can access appropriate healthcare and receive the necessary protection.Parents Urged to Prioritise VaccinationHealth professionals encourage parents and caregivers to ensure that their children receive recommended vaccines according to the national immunisation schedule.Parents are advised to keep vaccination cards, attend scheduled appointments and consult qualified healthcare workers when a child misses a dose.Healthcare providers can assess a child’s vaccination history and recommend an appropriate catch-up schedule where necessary.Public health experts also stress that vaccines protect not only individual children but also help reduce the spread of infectious diseases within communities.
