What type of immunity comes from when the immune system is exposed to antigens that provoke an immune response?

The type of immunity that results from the immune system being exposed to antigens that provoke an immune response is called adaptive immunity. This immunity develops over time as the body encounters specific pathogens and creates a tailored response, including the production of antibodies and memory cells. It can be acquired naturally through infection or artificially through vaccination. Adaptive immunity is characterized by its ability to remember past infections, providing long-lasting protection.
