Elena developed chicken pox when she was in first grade. Later in life, when her children developed chickenpox, she remained healthy even though she was exposed to countless virus particles daily. Explain why.

Is it possible for the immune system to eliminate the viruses without T cells? Why or why not?

When the patient's mother expresses concern about his sister being reinfected with chickenpox, what is the most appropriate response?   A) Your concerns are valid, but his sister developed an active natural immunity to chickenpox because she has already been infected. B) Your concerns are valid and there is a high likelihood that his sister will become infected again. We should probably administer the vaccine. C) Your concerns are valid and there is no way to protect his sister from becoming reinfected except to keep her at least 15 feet from your son at all times. D) Your concerns are valid and if his sister is reinfected, her symptoms will be less severe than her initial chickenpox infection.
