Primary Outcome Measures :
  1. Number of Participants with Solicited Local and Systemic Reactogenicity Adverse Reactions (ARs) [ Time Frame: Up to Day 176 ]
  2. Number of Participants with Unsolicited Adverse Events (AEs) [ Time Frame: Up to Day 197 (28-day follow-up after vaccination) ]
  3. Number of Participants with Any Serious AEs (SAEs), Medically Attended AEs (MAAEs), AEs Leading to Withdrawal From Study/Discontinuation of Study Vaccine, and AEs of Special Interest (AESIs) [ Time Frame: Day 1 to end of study (EOS) (Day 505) ]
  4. Number of Participants with Laboratory Abnormalities [ Time Frame: Up to Day 176 (7-day follow-up after vaccination) ]

Secondary Outcome Measures :
  1. Geometric Mean Titer (GMT) of B-Cell Neutralizing Antibody (nAb) and/or Antigen-Specific Binding Antibody (bAb) [ Time Frame: Days 1, 85, and 197 ]
  2. Geometric Mean Fold Rise (GMFR) of B-Cell nAb and Antigen-Specific bAb [ Time Frame: Days 1, 85, and 197 ]
  3. Number of Participants With Seroconversion of B-Cell nAbs and/or Antigen-Specific bAbs [ Time Frame: Days 1, 85, and 197 ]
    The number of initially EBV-negative participants with seroconversion from below the lower limit of quantification (LLOQ) to above the LLOQ for EBV-specific (vaccine antigen) binding and nAbs responses and the initially EBV-positive participants with > 2-, 3-, and 4-fold increases in serum binding or nAb titers from baseline (if above LLOQ) will be analyzed.

Criteria

Inclusion Criteria:

  • According to the assessment of the investigator, is in good general health and can comply with study procedures.

Exclusion Criteria:

  • Has had significant exposure to someone with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or COVID-19 in the past 14 days prior to the screening visit, if the participant has not been fully vaccinated against COVID-19 at least 14 days prior to the screening visit.
  • Has symptomatic acute or chronic illness requiring ongoing medical or surgical care, to include changes in medication in the past 2 months indicating that chronic illness/disease is not stable (at the discretion of the investigator).
  • Has a medical, psychiatric, or occupational condition that may pose additional risk as a result of participation, or that could interfere with safety assessments or interpretation of results according to the investigator's judgment.
  • Has a history of myocarditis, and/or pericarditis.
  • Has received or plans to receive any licensed or authorized vaccine, to include COVID-19 vaccines, ≤28 days prior to the first injection (Day 1) or plans to receive a licensed vaccine within 28 days before or after any study vaccine injection, with the exception of licensed influenza vaccines, which may be received more than 14 days before or after any study vaccine injection.

Note: Other inclusion and exclusion criteria may apply.
