Percentage of Participants Reporting Pre-specified Local Reactions: Infant Series Dose 1 (2 Months of Age)

Local reactions were reported using an electronic diary. Tenderness was scaled as Any (tenderness present); Significant (present and interfered with limb movement). Swelling and redness were scaled as Any (swelling or redness present); Mild (0.5 centimeters \[cm\] to 2.0cm); Moderate (2.5 to 7.0cm); Severe (greater than \[\>\] 7.0cm). Participants may be represented in more than 1 category.

Time frame: Within 4 days after dose 1 of Infant Series (2 months of age)

Population: Safety population: All participants who received at least 1 dose of the study vaccine; Number of participants analyzed (N) = those reporting yes for at least 1 day or no for all days for any local reaction.
