Live Vaccine Interval Rule

•  The Live Vaccine Interval rule (also referred to as the Live Virus rule) applies to all varicella vaccines. For rule details, see the Live Vaccine Interval rule on the General ICE Rules page.

Notes

• CVX 94 (MMRV) is not licensed for patients >= 13 years old. This does not affect evaluation; however, see the rule Vaccine Administered Outside of Licensed Age Range on the General ICE Rules page.

Series Name

• Varicella Series

Series Selection Rules

• There is only one series for this vaccine group.

Series Special Rules 

• Recommended interval between dose 1 and dose 2 is dependent upon the age of the patient at dose 1 (< or >= 13 years)
  
  • If the shot for target dose 1 is invalid, the recommended interval between the invalid shot and target dose 1 is 28 days.

Notes 

• ¹Per the Live Vaccine Interval rule, an absolute minimum interval of 28 days is required for CVX 94 (MMRV). For rule details, see the Live Vaccine Interval rule on the General ICE Rules page.
• ²The recommended interval for < 13 years of age differs from the CDC CDSi recommended interval of 3 years. While the recommended intervals differ, in practice ICE and CDC CDSi will come up with the same recommended due date. CDC CDSi only uses the recommended interval when the recommended age is not provided. See the CDC CDSi Logic Specification for details on how they calculate their recommended due date.
