Zoster Vaccine Group Evaluation and Forecasting Rules

General Rules for Zoster

General rules are not series-specific; general rules apply to the entire vaccine group.

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

The Select Adjuvant Product Interval rule applies to CVX 187. For rule details, see the Select Adjuvant Product Interval rule on the General ICE Rules page.

When recommending Zoster, always recommend at the CVX level; vaccine recommended should be CVX 187.

If a patient is administered CVX 187 < 52 days after a previously administered CVX 121 or CVX 188, evaluate the shot as Invalid/Below Minimum Interval.
If a patient is administered CVX 121 or CVX 188, evaluate the shot as Accepted/ VACCINE_NOT_PART_OF_THIS_SERIES. (new reason code)
- Absolute minimum interval between CVX 121 or CVX 188 to CVX 187 is 52 days.
- Recommended interval between CVX 121 or CVX 188 to CVX 187 is 56 days.

The Zoster series is complete after 2 doses.
