Description of intervention(s) / exposure
Treatment: Other - Ad26.RSV.preF
Treatment: Other - Placebo
Treatment: Other - Nimenrix

Experimental: Group 1: RSV Seronegative Toddlers (Ad26.RSV.preF) - Respiratory syncytial virus (RSV) seronegative toddlers will receive intramuscular (IM) injection of 2.5\*10\^10 viral particles (vp) of an adenovirus serotype 26- based vaccine encoding for the respiratory syncytial virus pre-fusion F-protein on Days 1, 29, and 57.

Placebo comparator: Group 2: RSV Seronegative Toddlers (Placebo/Nimenrix) - RSV seronegative toddlers will receive IM injection of placebo on Days 1, 29 and 57. Placebo can be replaced with Nimenrix on Day 57 in countries where applicable.


Treatment: Other: Ad26.RSV.preF
Ad26.RSV.preF will be administered as IM injection at a dose of 2.5\*10\^10 vp.

Treatment: Other: Placebo
Placebo will be administered as IM injection of sterile 0.9 percent (%) saline for injection.

Treatment: Other: Nimenrix
Nimenrix will be administered as 0.5 milliliter (mL) solution for IM injection.

* Participant is the product of a normal term pregnancy greater than or equal to (>=)37 weeks, with a minimum birth weight of 2.5 kilogram (kg)
* Participant must be in good health without any significant medical illness on the basis of physical examination, medical history, and vital signs performed at screening
* Participant has received all routine immunizations appropriate for his or her age according to local guidelines
* Each participant's parent(s)/legal guardian(s) must have access to a consistent means of contact either by telephone contact or email/computer

Can healthy volunteers participate?
Yes
Key exclusion criteria
* Participant's weight is below tenth percentile according to World Health Organization (WHO) pediatric growth and weight charts
* Participant has any clinically significant acute or chronic medical condition (for example, history of seizure disorders, bleeding/clotting disorder, autoimmune disease, active malignancy, systemic infections, congenital heart disease, history of any pulmonary condition requiring medication, atopy, reactive airway disease, medically-confirmed wheezing, bronchoconstriction or treatment with a beta 2 agonist, cystic fibrosis, bronchopulmonary dysplasia, chronic pulmonary disease, medically-confirmed apnea, hospitalization for respiratory illness, or mechanical ventilation for respiratory illness) that, in the opinion of the investigator, would preclude participation
* Participant is in receipt of, or planning to receive, live attenuated vaccine (for example, measles, mumps and rubella [MMR] or varicella, but excluding rotavirus vaccine) within 28 days of each study vaccination (that is, before and after); other vaccines (for example, influenza, pertussis, polio or rotavirus) should be given at least 14 days before or 14 days after each study vaccination
