Solicited symptoms were predefined symptoms or events to be specifically inquired about and assessed daily after vaccine administration up to 14 days after vaccination.
The solicited symptoms included fever greater than (>) 100.0 degrees F (37.8 degrees Celsius), runny nose, sore throat, cough, vomiting, muscle aches, chills, decreased activity and headache.
Results are reported for all solicited symptoms except fever >=101 degrees F (reported as primary outcome) within 7 days after vaccination and all solicited symptoms within 14 days after vaccination.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Periodo de tiempo: Within 7 and 14 days after vaccination

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
Treatment-emergent AEs were events between administration of study drug and up to 14 days after vaccination that were absent before treatment or that worsened relative to pre-treatment state.
Results are given for AEs reported within 7 days and 14 days after vaccination.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Treatment-emergent SAEs were serious events between administration of study drug and up to 180 days after the dose that were absent before treatment or that worsen relative to pretreatment state.
An NOCD was a newly diagnosed medical condition that was of a chronic, ongoing nature and was assessed by the investigator as medically significant.
Results are given for TESAEs and NOCDs reported within 28 days and 180 days after vaccination.
