What type of immunity is specifically generated by an immune response?

Active immunity is specifically generated by an immune response because it involves the body producing its own antibodies in response to a pathogen or infection. This type of immunity can develop after an individual is exposed to an infectious agent, either through natural means (such as infection) or through vaccination. When the immune system recognizes antigens from the pathogen, it triggers a complex response involving various immune cells and the production of antibodies that specifically target those antigens.

This process not only helps to eliminate the infection but also establishes immunological memory. As a result, if the individual is exposed to the same pathogen in the future, the immune system can mount a faster and more efficient response due to this memory.

In contrast, passive immunity involves the transfer of antibodies from another source, such as maternal antibodies transferred to an infant through breast milk, and does not involve an immune response from the individual itself. Innate immunity refers to the non-specific first line of defense mechanisms that the body has from birth, which do not provide specific protection against particular pathogens. Acquired immunity is often used interchangeably with active immunity but is a broader term that encompasses both active and passive immunity, making it less precise in this context.
