Final answer:
Active immunity is acquired when an individual's immune system responds to a pathogen or vaccine, as in the case of artificially acquired active immunity from vaccinations. Natural passive immunity is acquired through the transfer of antibodies, like when a baby receives them through breast milk. Vaccination leads to artificially acquired active immunity.
Step-by-step explanation:
Types of Acquired Immunity
Immunity that results from having an infection or from receiving an immunization is called active immunity. When a vaccine is administered, it leads to the development of immunological memory without causing the disease, which is referred to as artificially acquired active immunity. This has been a significant advance in medical history, resulting in the control or eradication of diseases such as smallpox, polio, and measles.
An example of natural immunity acquired passively is when a newborn receives antibodies from the mother through breast milk. This immunity is temporary, as the child does not produce the antibodies itself but receives them through passive transfer, hence the term passive immunity.
Vaccination triggers artificially acquired active immunity, as the individual's immune system actively responds to the vaccine by producing its own antibodies and developing a memory of the pathogen.
