Primary Outcome Measures
NameTimeMethod
Percentage of Participants With One or More Adverse Drug Reactions (ADRs)Up to 42 days after vaccination

An ADR is an AE (defined above) for which relatedness to the use of the product cannot be ruled out

Percentage of Participants With One or More Unexpected AEsUp to 42 days after vaccination

Unexpected AEs differed from AEs reported in the VARIVAX product label with regard to their identity, severity, specificity, or outcome

Percentage of Participants With One or More AEs by AgeUp to 42 days after vaccination

An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the study vaccine, is also an adverse event.

Changes resulting from normal growth and development which do not vary significantly in frequency or severity from expected levels are not to be considered adverse events. Examples of this may include, but are not limited to, teething, typical crying in infants and children, and onset of menses or menopause occurring at a physiologically appropriate time.

Percentage of Participants With One or More Serious Adverse Events (SAEs)Up to 42 days after vaccination

An SAE is any AE that results in death, is life-threatening, results in persistent or significant disability/incapacity, results in or prolongs an existing inpatient hospitalization, is a congenital anomaly/birth defect, is a cancer, is an overdose, or is another important medical event based on appropriate medical judgment.

Percentage of Participants With One or More Serious ADRsUp to 42 days after vaccination

A serious ADR is an SAE (defined above) for which relatedness to the use of the product cannot be ruled out

Percentage of Participants With One or More Unexpected SAEsUp to 42 days after vaccination

Unexpected SAEs differed from SAEs reported in the VARIVAX product label with regard to their identity, severity, specificity, or outcome

Percentage of Participants With One or More Adverse Events (AEs)Up to 42 days after vaccination

An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the study vaccine, is also an adverse event.

Examples of this may include, but are not limited to, teething, typical crying in infants and children, and onset of menses or menopause occurring at a physiologically appropriate time.
