- Percentage of Participants Reporting Fever (Oral Temperature >= 101 Degrees Fahrenheit) Through Day 8 [ Time Frame: Day 1 through Day 8 ]Percentage of participants with fever (oral temperature >= 101 degrees Fahrenheit) through Day 8 is reported.
- Number of Participants With Solicited Symptoms Through Day 8 [ Time Frame: Day 1 through Day 8 ]For this study, solicited symptoms included oral fever (> 100 degrees Fahrenheit), runny nose, sore throat, cough, vomiting, muscle aches, chills, decreased activity (tiredness), and headache.
- Number of Participants With Solicited Symptoms Through Day 15 [ Time Frame: Day 1 through Day 15 ]For this study, solicited symptoms included oral fever (> 100 degrees Fahrenheit), runny nose, sore throat, cough, vomiting, muscle aches, chills, decreased activity (tiredness), and headache.
- Number of Participants With Treatment-emergent Adverse Events (TEAEs) Through Day 8 and Day 15 [ Time Frame: Day 1 through Day 8; Day 1 through Day 15 ]An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.
- Number of Participants With Treatment-emergent Serious Adverse Events (TESAEs) Through Day 29 and Day 181 [ Time Frame: Day 1 through Day 29; Day 1 through Day 181 ]An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is 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. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.
- Number of Participants With New Onset Chronic Diseases (NOCDs) Through Day 29 and Day 181 [ Time Frame: Day 1 through Day 29; Day 1 through Day 181 ]An NOCD is a newly diagnosed medical condition that is of a chronic, ongoing nature and is assessed by the investigator as medically significant.
