How long should you wait for live vaccines after Cosentyx (secukinumab)?
Cosentyx (secukinumab) suppresses parts of the immune system by targeting IL-17A. Because of that, live vaccines are generally avoided during treatment and for a period after your last dose.
For patients on Cosentyx, the usual guidance is to wait at least 3 months after the last injection before receiving live vaccines. (This timing is based on the typical approach to live-vaccine safety after biologic immunosuppression.)
What counts as a “live vaccine” (so you don’t mix them up)?
Live vaccines contain weakened forms of the germ and include, for example:
- MMR (measles, mumps, rubella)
- Varicella (chickenpox)
- Live nasal spray influenza (not the shot)
- Yellow fever
If you’re unsure whether a vaccine is live, check the vaccine label or ask your pharmacist/clinic to confirm.
What if I need the vaccine sooner?
If you need protection quickly, clinics usually consider:
- Non-live (inactivated or recombinant) vaccines, which are typically allowed while on treatment when recommended for you.
- A tailored plan based on your dosing schedule and infection risk.
Does the answer change if I stop Cosentyx or miss doses?
The “wait after the last dose” approach generally applies whether you stop therapy or temporarily pause. In practice, your clinician may adjust the timing based on:
- how often you were dosing,
- how long you’ve been on therapy,
- your overall immune risk (for example, if you also take other immunosuppressants).
When should you check with your prescriber?
Contact your prescriber before getting any live vaccine if you:
- are currently taking Cosentyx,
- plan to restart soon,
- take other immune-altering medicines (such as corticosteroids, methotrexate, or other biologics),
- have a history of frequent or serious infections.
If you tell me which live vaccine you’re considering and when your last Cosentyx dose was (date), I can help you map the timing more precisely to that vaccine schedule.
