Active immunity involves the production of antibodies (by B lymphocytes) and cell-mediated response (with T lymphocytes). It renders relatively longer immunity (compared to passive immunity). Active immunity may be natural or artificial.
This type of active immunity is said to be natural because the immunity is induced not by deliberate exposure (such as vaccination). The individual has developed immunity to a live pathogen by having been exposed to it and by developing a primary immune response that led to immunological memory.
D. Active natural immunity. Breastfeeding provides infants with natural antibodies from the mother's milk, which helps to protect the baby through active immunity.

Natural active immunity to chickenpox is developed by being infected with chickenpox disease.
Natural Active Immunity
Natural active immunity typically results in longer lasting immunity compared to artificial active immunity. This is because natural exposure to a pathogen triggers a stronger and more diverse immune response, leading to the development of memory cells that can provide long-term protection against future infections.
The mother's breast milk provides passive natural immunity to the baby. This means that the baby receives antibodies from the mother through the breast milk, offering temporary immunity protection until the baby's immune system is more developed.

Active immunity will generally occur when a person is exposed to pathogens. This will happen when a disease develops as a result of agents that cause diseases.
