Measles mumps and rubella vaccine + Muromonab cd3

Severity: Contraindicated

Measles mumps and rubella vaccine and Muromonab cd3: contraindicated interaction.

Last updated

For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Muromonab-CD3 causes profound T-cell depletion, so the live attenuated vaccine viruses may replicate unchecked and cause disseminated vaccine-strain disease. The vaccine response is also likely to be inadequate.

What this interaction means in plain words

Measles mumps and rubella vaccine and Muromonab cd3 are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.

Evidence level: Moderate

Why it happens

Profound T-cell depletion and immunosuppression permit uncontrolled replication of live attenuated viruses and blunt vaccine immunogenicity.

What to do

Do not give live MMR vaccine during or shortly after muromonab-CD3 therapy; defer until immune recovery is confirmed and use inactivated vaccines where appropriate.
