Can you get the MMR vaccine while taking Cosentyx (secukinumab)?
MMR is a live, attenuated vaccine. Cosentyx (secukinumab) is a biologic that can suppress parts of the immune system, and guidance for this class of therapy generally advises avoiding live vaccines during treatment. That means you should not get the MMR vaccine while you are actively taking Cosentyx unless your prescribing clinician specifically says it is safe for you.
What if you need MMR because you’re not immune?
If you need MMR (for example, for travel, school/work requirements, or because you’re not immune), clinicians often plan it around the timing of immunosuppressive therapy. A common approach is to give any needed live vaccines before starting Cosentyx, when possible, or to check your immunity (e.g., by blood testing) so you only vaccinate if you’re actually non-immune.
What vaccines are usually preferred instead?
If you’re on Cosentyx, non-live vaccines are typically the safer option. Your clinician or pharmacist can confirm what vaccines you’re eligible for based on your vaccination record and local recommendations.
How should you talk to your doctor?
Bring your vaccination history and your current Cosentyx schedule (dose and timing). Ask:
- Whether you are considered safe to receive a live vaccine in your specific situation.
- Whether MMR can be replaced with immunity testing or a non-live alternative.
- If you might need a plan to vaccinate before the next Cosentyx dose or before you start therapy.
Practical next step
Contact your rheumatologist/dermatologist (who prescribes Cosentyx) or your primary care clinician and tell them you want MMR while on Cosentyx. They can make a clear “yes/no” decision for your case and help you plan timing if vaccination is needed.
If you tell me your age, why you need MMR (routine vs travel/school), and whether you’ve had MMR before, I can help you think through the likely options to discuss with your clinician.
