An otherwise healthy student in your class was infected with Epstein Barr virus (EBV) (the virus that causes infectious mononucleosis) when she was a child, at which time she had merely experienced a mild sore throat and swollen lymph nodes in her neck. When she is exposed to EBV again later in life, she does not get sick or develop any symptoms of mononucleosis. Which of the following statements explains why your classmate does not exhibit symptoms of EBV infection? O Complement proteins effectively controlled the EBV during the second infection. none of these O She was infected with a weaker strain of EBV during her second exposure. Her innate immune response was better at recognizing the EBV antigen during the second infection. O Memory T cells recognized the virus upon the second exposure and activated cells that destroyed the virally infected cells.
