Outcome Measures

Primary Outcomes (9)

  • Percentage of Participants With One or More Adverse Events (AEs)

    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.

    Up to 42 days after vaccination

  • Percentage of Participants With One or More AEs by Gender

    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.

    Up to 42 days after vaccination

  • Percentage of Participants With One or More AEs by Age

    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.

    Up to 42 days after vaccination

  • Percentage of Participants With One or More Adverse Drug Reactions (ADRs)

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

    Up to 42 days after vaccination

  • Percentage of Participants With One or More Unexpected AEs

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

    Up to 42 days after vaccination

  • Percentage of Participants With One or More Unexpected ADRs

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

    Up to 42 days after vaccination

  • Percentage of Participants With One or More Serious Adverse Events (SAEs)

    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.

    Up to 42 days after vaccination

  • Percentage of Participants With One or More Serious ADRs

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

    Up to 42 days after vaccination

  • Percentage of Participants With One or More Unexpected SAEs

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

    Up to 42 days after vaccination
