Concerns have heightened among public health circles following a recent study which revealed that 27 per cent of children failed to develop immunity against measles despite receiving the vaccine. The study highlights a troubling lack of antibody response, particularly among children aged 9 to 14 months. Experts warn that the current immunisation approach is falling short of expectations, necessitating an urgent overhaul of the national vaccination strategy and delivery systems.
The health administration initiated a nationwide measles-rubella vaccination campaign on 20 April, following a notable outbreak of the disease in March. The emergency campaign targeted all children aged between six months and five years, concluding on 20 May. Prior to the rollout, senior health officials had expressed confidence that infections would be brought under control within three to four weeks after the campaign's conclusion. However, persistent transmission and subsequent research findings have challenged those initial projections.
According to the researchers, this was the first study of its kind in the country to comprehensively assess measles immunity among children under the age of five following a national campaign. The research was spearheaded by the Institute of Epidemiology, Disease Control and Research (IEDCR). A total of 12 researchers and officials from key national and international health bodies—including the Directorate General of Health Services (DGHS), the Directorate General of Drug Administration (DGDA), the Institute of Public Health, and the Eastern Mediterranean Public Health Network—collaborated on the investigation.
The unexpected findings have prompted urgent calls for a thorough review of vaccine efficacy, storage conditions, and cold chain maintenance across the country. Public health specialists emphasise that identifying the exact causes behind the failure of the vaccine to trigger an immune response in over a quarter of vaccinated children is paramount. Without immediate, corrective interventions in the immunization framework, vulnerable young populations will remain exposed to future outbreaks of the highly contagious virus.
