The relationship between age and immune functions
Your immunity is your body’s natural defence against malignant substances such as bacteria, viruses, cancer cells or foreign tissues. The strength of your immune system is represented by its ability to produce cells that identify and destroy other potentially harmful cells. However, it’s important to note that your immune function changes over time. When babies are born, their immune systems are immature. As babies grow into adults, their immune functions continue to develop, and learn to fight off pathogens better. However, the strength of their immune system will decline with old age1. Read on to find out how your immune system changes over time.
