Timeframe: Through Day 336 or early withdrawal

Population: Analyses were performed on the total vaccinated cohort (TVC), which includes all immunized subjects.

Blood and urine samples were collected at screening for all evaluations with additional blood samples obtained on Days 28, 56, 84, 168, 196, 280, and 336. The following clinical laboratory evaluations were performed: Biochemistry: alanine aminotransferase; aspartate aminotransferase; creatinine; blood urea nitrogen; Hematology: neutrophils, lymphocytes, eosinophils, hemoglobin, platelet count, white blood cell count; Infection status: HIV, hepatitis B, hepatitis C, and cytomegalovirus; and Urinalysis: blood, glucose, protein.

SECONDARY outcome

Timeframe: Through Day 336 or early withdrawal

Population: Analyses were performed on the total vaccinated cohort (TVC), which includes all immunized subjects.

To measure the avidity of responses against CMV gB protein, a standard ELISA assay using recombinant gB protein which did or did not include treatment with 5M urea for 30 minutes of samples after sera had been incubated with recombinant protein. The reported value, or Avidity Index, represents the percent of signal measured in ELISA after treatment with urea relative to samples not exposed to urea.
