Primary Outcome Measures :
- Number of Participants With an Occurrence of Breakthrough Varicella [ Time Frame: From 6 weeks to 168 months (14 years) post vaccination ]Parents/guardians of Varivax vaccinated children were interviewed every 6 months after vaccination. The number of participants with varicella (referred to as varicella with "any symptoms") were reported by parents during the interview. No medical confirmation of the diagnosis was required.
- Incidence Rate of Breakthrough Varicella [ Time Frame: From 6 weeks to 168 months (14 years) post vaccination ]Parents/guardians of Varivax vaccinated children were interviewed every 6 months after vaccination. The number of participants with varicella (referred to as varicella with "any symptoms") were reported by parents during the interview. No medical confirmation of the diagnosis was required.
Secondary Outcome Measures :
- Number of Participants With an Occurrence of Herpes Zoster Infection [ Time Frame: From 6 weeks to 168 months (14 years) post vaccination ]Herpes zoster cases were physician-diagnosed cases.
- Incidence Rate of Herpes Zoster Infection [ Time Frame: From 6 weeks to 168 months (14 years) post vaccination ]Herpes zoster cases were physician-diagnosed.
