What type of immunity develops after the introduction of a vaccine?

Artificial immunity develops after the introduction of a vaccine because it involves the deliberate exposure of the immune system to a weakened or inactive form of a pathogen. This exposure helps the body recognize and respond more effectively to future infections by that pathogen without having to endure the actual disease. Vaccination stimulates the immune system to produce antibodies and memory cells that provide long-lasting protection, which is the core principle of artificial immunity.

Passive immunity, on the other hand, occurs when a person receives antibodies from another source, such as through maternal transfer or intravenous immunoglobulin, but does not involve the person's own immune response. Naturally acquired immunity develops through exposure to pathogens in everyday life, allowing the body to build immunity organically, while innate immunity refers to the body's first line of defense, which includes physical barriers and immune responses that are always present and ready to act against pathogens.
