Active and Passive Immunity Explained

The video tutorial explains the concept of immunity, which is the body's ability to fight infections. It distinguishes between two main types: active and passive immunity. Active immunity involves the body's production of antibodies and T cells to combat specific pathogens, often through natural infection or vaccination. Vaccines introduce weakened antigens to stimulate an immune response without causing disease symptoms. Passive immunity, on the other hand, is temporary and involves the transfer of antibodies, such as from mother to child. The video highlights the importance of vaccines in preventing diseases and improving human health.
