What are two way to develop immunity?

Immunity can be developed through active and passive means. Active immunity occurs when the body produces its own antibodies in response to an infection or vaccination, providing long-lasting protection. Passive immunity, on the other hand, is acquired when antibodies are transferred from another source, such as through maternal antibodies in breast milk or through antibody treatments, offering temporary protection. Both methods play crucial roles in the immune system's ability to fight infections.
