Measles, caused by the measles virus, remains a significant cause of morbidity in children worldwide despite the availability of effective vaccines. Infants and young children are especially vulnerable, as their immune systems are still maturing. Breastfeeding provides both nutritional and immunological benefits, potentially influencing disease severity and outcomes in various pediatric infections, including measles. This article examines the clinical course of measles in children who are breastfed compared to those who are not, with a focus on immunological mechanisms, maternal antibody transfer, and implications for disease management and prevention.
