- For the CMV-seropositive Cohorts: at the screening visit, is CMV IgG-positive and CMV IgM-negative, or CMV IgG-Positive and CMV IgM-positive. Participants with an isolated positive result for CMV IgM (ie, CMV IgG-negative and CMV IgM- positive) will not be eligible for enrollment but may be rescreened after at least 6 weeks from the initial CMV Screening. A participant with a CMV IgG-positive result and an IgM-indeterminate result at Screening will not require the IgM sampling to be repeated in order to consider the participant seropositive.

- Female participants of childbearing potential: urine pregnancy test is negative at screening and negative on the day of the first injection (day 1). Note: urine pregnancy test at screening or day 1 is not required for female participants of nonchildbearing potential.
- Female participants of childbearing potential: if the participant is sexually active with men, all of the following criteria must be met. a) has practiced adequate contraception or has abstained from all activities that could result in pregnancy for at least 28 days prior to the first injection (Day 1). b) Agrees to continue adequate contraception through 3 months following the third study injection (Month 9/Day 257). Adequate contraception is defined as consistent ands correct use of an approved contraceptive method in accordance with the product label, or sterilization of a monogamous male partner prior to study enrollment.
