  1. Bolded values indicate development of antibody response, which is defined as a 2-fold increase in titer of the post-immunization sample as compared to the corresponding negative control sample. aND: not determined. Because the time 0 sample is the negative control sample for the CEA ELISA, a titer cannot be assigned to this sample. bFor this patient, the sample collected approximately 2 weeks after the day 70 vaccination was labeled "Extension Phase Month 1"; for all other patients, the sample collected one month after the day 70 vaccination was labeled "Extension Phase Month 2".
