Injecting a person with a vaccine so the body will create antibodies against a disease is an example of which type of immunity?

Injecting a person with a vaccine to stimulate the body to produce antibodies against a disease is an example of active immunity. This type of immunity occurs when the immune system is exposed to a harmless form of the pathogen, prompting it to generate a specific immune response. Unlike passive immunity, where antibodies are transferred from another source, active immunity involves the individual's own immune system actively producing antibodies.
