Question

One of the foundations of vaccination is generating an antibody response against your virus. The antibody response is one part of the adaptive immune response. Which of the following are characteristics of an adaptive immune response?
1. The adaptive immune response can recognize and respond to an almost limitless array of antigens.
2. Each antibody produced by the immune response is specific to one specific antigen (surface molecule) on one specific pathogen.
3. The adaptive immune response does not distinguish between self molecules and foreign molecules.
4. A new immune response must be mounted from the very beginning with each exposure to an antigen/pathogen (even if the body has been exposed to that antigen before).

Answer 1

Answer: 1. The adaptive immune response can recognize and respond to an almost limitless array of antigens

Explanation: part of the immune response depends on the antibodies that our body has. These antibodies can recognize antigens which are molecules in the surface of the pathogens, attach to them and destroy or block the harmful effects of pathogens.

Adaptive response allow to the cells of the immune system to develope and synthesize new antibodies. This is helpful because cells can recognize different pathogens, attack them and increase the immunological response of the body or even attack different pathogens at the same time.
