The development of immune competence in early life is foundational for pediatric health. Recent revelations in immunology provide key insights for practitioners in supporting this critical process.
The immune system is the body’s defense force, working non-stop to identify and eradicate invading pathogens. This protection is particularly vital in children as their bodies are still growing and developing immunologic maturity. The pediatric immune system consists of two complementary branches: innate and adaptive immunity. Innate immunity forms the first line of defense present from birth, providing rapid, generalized protection against pathogens.
