Adults usually have developed adaptive immunity toward the Epstein-Barr virus, which means their body has developed specific antibodies to recognize and fight the virus. Passive immunity is when antibodies are passed from another source, such as a mother to a child through breast milk, and innate immunity is the body's general defense mechanism.
