Which type of immunity is developed through vaccination?

Vaccination is a process that introduces a weakened or inactive form of a pathogen or its components into the body, which stimulates the immune system to respond and build protection against that specific disease. This leads to the development of immunity, specifically referred to as artificial active immunity.

Artificial active immunity occurs when the immune system is exposed to an antigen through vaccination. In response, the body produces antibodies and memory cells, which enable it to fight off the disease more effectively in the future if exposed to the actual pathogen. This is distinct from natural active immunity, which is acquired through direct exposure to a disease-causing organism, leading to an immune response after the infection has occurred.

The other forms of immunity mentioned do not pertain to vaccinations. Natural passive immunity is acquired through the transfer of antibodies from mother to child, such as through breast milk. Artificial passive immunity involves the injection of antibodies from another source, providing temporary protection without the individual's immune system actively engaging with the pathogen.

Thus, artificial active immunity is the correct answer because it directly relates to the immune response generated by vaccinations that stimulate the body to produce its own antibodies and memory cells.
