Active Immunity: How It Works & Difference from Natural Infection

No, active immunity does not involve a person becoming immune to a pathogen as a result of having the disease. In active immunity, the person's immune system is actively stimulated to produce antibodies against a specific pathogen, either through vaccination or natural infection. This process allows the immune system to mount a faster and more effective response if the person comes into contact with the pathogen again in the future.

On the other hand, passive immunity involves the transfer of ready-made antibodies or immune cells from one individual to another. This type of immunity is temporary and does not provide long-term protection.
