2. Many people become infected with the chicken pox virus during childhood. After recovering from chicken pox, these people are usually immune to the disease for the rest of their lives. However, they may still be infected by viruses that cause other diseases, such as measles. Discuss the immune response to the chicken pox virus. In your answer, be sure to include: • the role o antigens in the immune response • the role of white blood cells in the body's response to the virus • an explanation of why recovery from an infection with the chicken pox virus will not protect a persom from getting a different disease, such as measles • an explanation of why a chicken pox vaccination usually does not cause a person to become ill with chicken pox

Defense Mechanism

Circumstances influence and compel people to behave in a certain way. One such behavior is a defense mechanism. It is employed by people to escape from unpleasant circumstances, thoughts and actions. Defense mechanisms are, thus, psychological strategies that help to avert and avoid unwanted feelings such as guilt or shame and situations such as threat and danger.
