Brief Summary:
This study will evaluate the safety, tolerability, and efficacy of Human Cytomegalovirus (CMV) vaccine V160 administered in a 2-dose or 3-dose regimen in healthy seronegative women 16 to 35 years of age. Participants will receive blinded V160 on Day 1, Month 2, and Month 6 (3-dose regimen), V160 on Day 1 and Month 6 and placebo at Month 2 (2-dose regimen), or placebo on Day 1, Month 2, and Month 6, and will be followed to approximately Month 36. The primary hypothesis of the study is that administration of a 3-dose regimen of V160 will reduce the incidence of primary CMV infection compared to placebo.

Arm Intervention/treatment
Experimental: V160 3-Dose Regimen
Participants will receive V160 vaccination by intramuscular (IM) injection on Day 1, Month 2, and Month 6.
Biological: V160
V160 administered as a 0.5 mL (100 Units) IM injection containing Merck aluminum phosphate adjuvant (MAPA)

Experimental: V160 2-Dose Regimen
Participants will receive V160 vaccination by IM injection on Day 1 and Month 6 and placebo at Month 2.
Biological: V160
V160 administered as a 0.5 mL (100 Units) IM injection containing Merck aluminum phosphate adjuvant (MAPA)

Drug: Placebo
Saline solution administered as a 0.5 mL IM injection

Placebo Comparator: Placebo
Participants will receive placebo by IM injection on Day 1, Month 3, and Month 6.
Drug: Placebo
Saline solution administered as a 0.5 mL IM injection

Primary Outcome Measures :
  1. Incidence of Cytomegalovirus Infection in the 3-dose Regimen Group [ Time Frame: Up to Month 36 ]
    CMV infection is defined as detection of CMV (non-vaccine type) by polymerase chain reaction in a single saliva or urine sample in a previously CMV-uninfected participant. The incidence of CMV infection in participants receiving the 3-dose V160 regimen will be assessed.

  2. Solicited Injection-site AEs [ Time Frame: Up to 5 days after each vaccination ]
    The percentage of participants with one or more solicited injection-site AE (pain/tenderness, erythema/redness, swelling) will be assessed.

  3. Solicited Systemic AEs [ Time Frame: Up to 14 days after each vaccination ]
    The percentage of participants with one or more solicited systemic AEs (headache, fatigue, muscle pain, joint pain) will be assessed.

  4. Vaccine-related Serious Adverse Events (SAEs) [ Time Frame: Up to 14 days after each vaccination ]
    The percentage of participants with a vaccine-related SAE will be assessed.

Secondary Outcome Measures :
  1. Incidence of Cytomegalovirus Infection in the 2-dose Regimen Group [ Time Frame: Up to Month 36 ]
    CMV infection is defined as detection of CMV (non-vaccine type) by polymerase chain reaction in a single saliva or urine sample in a previously CMV-uninfected participant. The incidence of CMV infection in participants receiving the 2-dose V160 regimen will be assessed.
