Can the MMR Vaccine Be Given During Cosentyx Therapy?
No, the MMR vaccine should not be given during Cosentyx (secukinumab) therapy. Cosentyx is an IL-17 inhibitor that suppresses the immune system, increasing risks of vaccine-related infections from live vaccines like MMR (measles, mumps, rubella).[1][2]
Why Live Vaccines Are Contraindicated with Cosentyx
Cosentyx prescribing information explicitly contraindicates live vaccines due to immunosuppression. Administering MMR—a live attenuated vaccine—could lead to uncontrolled replication of the vaccine virus, causing vaccine-derived disease in patients with weakened immunity.[1][3] Guidelines from the CDC and ACIP recommend avoiding live vaccines in patients on biologic immunomodulators like secukinumab.[4]
What About Inactivated Vaccines?
Inactivated or recombinant vaccines (e.g., flu shot, Tdap, or COVID-19 vaccines) can generally be given during Cosentyx therapy, as they do not replicate. Discuss timing and need with a healthcare provider to ensure adequate immune response.[1][4]
How Long to Wait Before or After Starting Cosentyx
- Before starting Cosentyx: Complete live vaccines like MMR at least 4 weeks prior to the first dose.[1][2]
- After stopping Cosentyx: Wait 4-6 months (or longer, based on provider assessment) before giving live vaccines, as immune recovery varies.[1][3]
Exceptions or Special Cases
No routine exceptions exist for MMR during active Cosentyx use. In emergencies or high-risk outbreaks (e.g., measles exposure), consult infectious disease specialists—risk-benefit analysis is case-specific, but live vaccines remain discouraged.[4] Pediatric patients or those with autoimmune conditions like psoriasis or psoriatic arthritis (common Cosentyx indications) follow the same rules.[1]
Patient and Provider Next Steps
Check vaccination status before starting Cosentyx. Serologic testing can confirm MMR immunity without needing the vaccine. Always consult a rheumatologist, dermatologist, or primary care provider for personalized advice, as individual immune status matters.[2][4]
