Study Endpoints

Primary Endpoints

Incidence of solicited symptoms after Dose 1
Through Day 28 after each dose

Solicited symptoms are predefined symptoms or events to be specifically inquired about and assessed daily during the 28-day period after vaccine administration. The solicited symptoms for this study include: fever \>100.4°F (\>38.0 °C) regardless of route, runny/stuffy nose, cough, drowsiness, loss of appetite/decreased urine output, irritability/Fussiness, oropharyngeal irritation (laryngitis), epistaxis

Incidence of solicited symptoms after Dose 2
Through Day 28 after each dose

Solicited symptoms are predefined symptoms or events to be specifically inquired about and assessed daily during the 28-day period after vaccine administration. The solicited symptoms for this study include: fever \>100.4°F (\>38.0 °C) regardless of route, runny/stuffy nose, cough, drowsiness, loss of appetite/decreased urine output, irritability/Fussiness, oropharyngeal irritation (laryngitis), epistaxis

Incidence of solicited symptoms after Dose 3
Through Day 28 after each dose

Solicited symptoms are predefined symptoms or events to be specifically inquired about and assessed daily during the 28-day period after vaccine administration. The solicited symptoms for this study include: fever \>100.4°F (\>38.0 °C) regardless of route, runny/stuffy nose, cough, drowsiness, loss of appetite/decreased urine output, irritability/Fussiness, oropharyngeal irritation (laryngitis), epistaxis

Incidence of adverse events (AEs) after Dose 1
Through Day 28 after each dose

As defined by the ICH Guideline for Good Clinical Practice, an AE is: Any untoward medical occurrence in a participant or clinical investigations subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event (AE) can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

Incidence of AEs after Dose 2
Through Day 28 after each dose

As defined by the ICH Guideline for Good Clinical Practice, an AE is: Any untoward medical occurrence in a participant or clinical investigations subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event (AE) can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

Incidence of AEs after Dose 3
Through Day 28 after each dose

As defined by the ICH Guideline for Good Clinical Practice, an AE is: Any untoward medical occurrence in a participant or clinical investigations subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event (AE) can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

Incidence of medically-attended lower respiratory illnesses (MA-LRIs) after Dose 1
Through Day 28 after each dose

An MA-LRI is defined as a health care provider confirmed diagnosis of any one or more of the following events: wheezing, pneumonia, croup (laryngotracheobronchitis), rhonchi (not cleared with cough or suctioning), rales (not cleared with cough or suctioning), bronchitis, bronchiolitis, apnea

Incidence of MA-LRIs after Dose 2
Through Day 28 after each dose

An MA-LRI is defined as a health care provider confirmed diagnosis of any one or more of the following events: wheezing, pneumonia, croup (laryngotracheobronchitis), rhonchi (not cleared with cough or suctioning), rales (not cleared with cough or suctioning), bronchitis, bronchiolitis, apnea

Incidence of MA-LRIs after Dose 3
Through Day 28 after each dose

An MA-LRI is defined as a health care provider confirmed diagnosis of any one or more of the following events: wheezing, pneumonia, croup (laryngotracheobronchitis), rhonchi (not cleared with cough or suctioning), rales (not cleared with cough or suctioning), bronchitis, bronchiolitis, apnea

Incidence of SAEs
Administration of Dose 1 (Day 0) through Day 28 post final dose

An SAE is any adverse event that results in any of the following outcomes: death; life-threatening; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability or incapacity; congenital anomaly/birth defect (in the offspring of a subject); an important medical event that may not result in death, threaten life or require hospitalization may be considered a serious adverse event when, based upon appropriate medical judgment, it may jeopardize the subject and may require medical or surgical intervention to prevent one of the outcomes listed above.
