There are many disease that do not infect a person more than once, such as chicken pox and measles. what is responsible for this lifetime immunity?

a. the innate immune response, because barriers to entering the body improve with age.
b. the innate immune response, because adults have more white blood cells than children.
c. the acquired immune response, because antibodies are developed from previous infections.
d. the acquired immune response, because it responds rapidly to broad classes of pathogens.



Answer :

The factor responsible for the lifetime immunity against certain diseases like chicken pox and measles, that do not infect a person more than once is  (c) the acquired immune response, because antibodies are developed from previous infections.

The acquired immune response is the specific type of immunity that develops for a certain type of pathogen. This immunity is achieved when the antibodies are received from an outside source such as vaccine. It is a more stronger type of immunity as it stays for a longer time, preferably for lifetime and also has memory.

Antibody is  Y-shaped structure present inside the body. It is a compound formed to fight against any pathogen also called antigen. Antibody recognizes specific component on a pathogen and protects the body.
