MMR Vaccine Group Evaluation and Forecasting Rules

General Rules for MMR

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

Proof of Immunity Rules

If a patient has immunity (reported as having a positive titer or serology) for all three antigens (measles, mumps, rubella), then the Recommendation is Not Recommended and the reason code is PROOF_OF_IMMUNITY.
Any shot administered prior to the date of immunity is evaluated as Valid or Invalid, based on minimum age and minimum interval rules.
If the series is not complete and the patient is administered a shot where the vaccine contains only the antigen(s), or a subset of the antigen(s) with previously reported proof of immunity, the shot is evaluated as Accepted with a reason code of PROOF_OF_IMMUNITY.²

Live Vaccine Interval Rule

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

Series Completion Special Rule

Once a patient completes the MMR series the Recommendation is Not Recommended and the reason code is COMPLETE_HIGH_RISK. (MMR should never have a recommendation of Not Recommended/Complete.)

Notes

²For example, patient DOB = 1/1/2022. Patient receives proof of immunity for Mumps on 1/1/2023.
- Scenario #1 - MMR (CVX 03) administered on 2/1/2023 = Valid, OR
- Scenario #2 - Mumps/ Rubella (CVX 38) administered on 2/1/2023 = Valid, OR
- Scenario #3 - Mumps (CVX 07) administered on 2/1/2023 = Accepted / PROOF_OF_IMMUNITY
²For example, patient DOB = 1/1/2022. Patient receives proof of immunity for Mumps and Measles on 1/1/2023.
- Scenario #1 - Mumps (CVX 07) administered on 2/1/2023 = Accepted / PROOF_OF_IMMUNITY

MMR Vaccines

CVX Code	Name
03	MMR
05	measles
06	rubella
07	mumps
04	measles/rubella
38	mumps/rubella

CVX Code Specific Rules

Component Rules

If components (measles, mumps, rubella, measles/rubella, mumps/rubella) are reported and are valid, and if there is at least one dose of each antigen (measles, mumps, and rubella), then this will be considered equal to a single dose of MMR. The MMR series is complete after 2 doses.

Combination Vaccines that Include MMR

CVX Code	Vaccine Name	Component CVX Code	Component Vaccine Name
94	MMRV	03	MMR

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.

DOB prior to 1/1/1957

For persons born prior to 01/01/1957, if the series is NOT complete, then the Recommendation is Conditional and the reason code is HIGH_RISK.

Series Complete with 1 Dose

If the recommended due date for Target Dose 2 is >= 19 years old, then that dose is not required; the series is complete with 1 dose.

Notes

¹Per the Live Vaccine Interval rule, an absolute minimum interval1 of 28 days is required for CVX 94 (MMRV). For rule details, see the Live Vaccine Interval rule on the General ICE Rules page.
