Significance of Active immunity
Active immunity is defined as the immunity acquired through exposure to pathogens or immunization. It develops when an individual encounters an infection or undergoes vaccination, leading to the formation of antibodies and specialized immune cells. This type of immunity is characterized by the development of immunologic memory, allowing the body to respond more effectively to future infections from the same pathogens.
