The immune system of a neonate is not fully developed, making them more vulnerable to infections. However, several factors contribute to bolstering their immunity:
Breastfeeding: Breast milk is rich in antibodies, particularly Immunoglobulin A (IgA), which protects against pathogens. It also contains immune cells, growth factors, and other bioactive molecules that enhance the neonate's immune response. Colostrum: The first milk produced by the mother, colostrum, is particularly rich in antibodies and has a higher concentration of proteins and nutrients, providing crucial immunological protection. Maternal Antibodies: During the last trimester of pregnancy, maternal antibodies are transferred to the fetus through the placenta. These antibodies provide passive immunity, protecting the neonate from infections encountered by the mother. Vaccination: Early vaccination schedules are designed to protect neonates from common infections. Vaccines stimulate the neonate's immune system to produce antibodies and memory cells, which provide long-term immunity.
