Can you get an MMR vaccine if you’re taking Cosentyx (secukinumab)?
Cosentyx (secukinumab) is a biologic that blocks interleukin-17A and can affect immune responses. MMR is a live, attenuated vaccine, and guidance for patients on biologic immune therapies is usually to avoid live vaccines unless your specialist explicitly clears you.
Because vaccine recommendations depend on your exact treatment plan and dose, the safest next step is to ask your prescriber (dermatology or rheumatology) and the clinician giving the vaccine whether live vaccines like MMR are allowed for you personally.
Why MMR specifically matters (live vs. non-live vaccines)
MMR contains live, weakened viruses. Many immune-altering medicines (including some biologics used for psoriasis, psoriatic arthritis, and ankylosing spondylitis) may increase the risk that a live vaccine could cause problems rather than just protection.
If you’re offered an alternative, non-live vaccine options may be considered depending on what protection you need.
What should you do before getting MMR while on Cosentyx?
Ask these exact questions at your appointment:
- “Is MMR considered a live vaccine for my situation?”
- “Should I stop or delay Cosentyx to get MMR, or is it not recommended?”
- “If I can’t get MMR now, when would it be safe to get it?”
Your prescriber will weigh your disease control risk (for example, psoriasis/arthritis flares) against vaccine timing.
When would a clinician consider giving MMR?
In practice, live vaccines are more often considered:
- before starting the biologic, or
- after a period of stopping medication if it’s considered appropriate for that specific drug and patient.
The correct timing is individualized and should come from your treating specialist.
If you already got MMR, is that dangerous?
One dose doesn’t automatically mean harm, but you should contact your prescriber promptly to ask about follow-up. Seek urgent care if you develop severe fever, widespread rash, breathing problems, or other concerning symptoms.

I don’t have enough provided information here to cite specific Cosentyx/MMR guidance from a database. If you share the dosing schedule (every 2 weeks vs monthly), what condition you’re treating (psoriasis, psoriatic arthritis, ankylosing spondylitis), and whether your doctor has ever said your vaccines should be “live” vs “non-live,” I can tailor the safest next questions to ask your clinician.
