Artificial active immunity and artificial passive immunity are two different approaches to immunization that help the body fight infections.
Artificial active immunity involves the introduction of antigens into the body, which stimulates the immune system to produce antibodies against those antigens. This is typically achieved through vaccination, where weakened or inactivated forms of pathogens are administered. The body then develops a memory response, allowing it to recognize and fight off the same pathogen in the future.
On the other hand, artificial passive immunity involves the direct introduction of antibodies into the body. This can be done through therapies using antibody-rich blood products or serum derived from an immune individual. While this method provides immediate protection against certain diseases, it does not stimulate the recipient’s immune system to produce its own antibodies, meaning the protection is temporary and does not involve the creation of immunological memory.
In summary, the difference lies in the use of antigens to stimulate the immune response in artificial active immunity, while artificial passive immunity relies on the immediate provision of pre-formed antibodies. Therefore, the correct answer to the question is:
Answer: A – antigens (for artificial active) and antibodies (for artificial passive).
