- Chronic use of oral steroids (equivalent to 20 milligram per day \[mg/day\] prednisone greater than or equal to \[\>=\] 12 weeks / \>= 2 milligram per kilogram \[mg/kg\] body weight / day prednisone \>= 2 weeks) within 60 days prior to Day 1 (use of inhaled, intranasal, or topical corticosteroids is allowed).
- Receipt of parenteral steroids (equivalent to 20 mg/day prednisone \>= 12 weeks / \>= 2 mg/kg body weight / day prednisone \>= 2 weeks) within 60 days prior to Day 1.
- Receipt of immunostimulants within 60 days prior to Day 1.
- Receipt of parenteral, epidural or intra-articular immunoglobulin preparation, blood products, and/or plasma derived products within 3 months prior to Day 1 or planned during the full length of the trial. In addition, participants must be advised not to donate blood during the study period.
- Known Human Immunodeficiency Virus (HIV) infection or HIV-related disease.
- Genetic immunodeficiency.
- Has known current or chronic hepatitis B and/or hepatitis C infections.
- Has abnormalities of spleen or thymic function.
- Has a known bleeding diathesis, or any condition that may be associated with a prolonged bleeding time.

- Individuals who received any other vaccines within 14 days (for inactivated vaccines) or 28 days (for live vaccines) prior to enrollment in this trial or who are planning to receive any vaccine within 28 days of investigational vaccine/placebo administration.
- Female participants who are pregnant or breastfeeding, or are planning to become pregnant.
