Cytomegalovirus (CMV) is an important cause of illness and occasional deaths in infants who catch the virus before they are born, in newborns, and in children and adults who have weak immune systems. The purpose of this study is to look at how the CMV vaccine works in the blood. This study is being done along with the main CMV gB/MF59 vaccine study that looks at how the overall body reacts to the vaccine. Participants will include up to 100 healthy adolescent female subjects aged 12 to 17 years who were vaccinated in study 04-039 and 100 subjects that were screened for 04-039 to participate as controls. Study procedures will include up to 6 blood draws taken over a 13 month period. Participation will be about 31 months (unless the patient enrolls into the shedding study).
