What's the recommended wait time for live flu vaccine after cosentyx?

Cosentyx (secukinumab) is an IL‑17 inhibitor that suppresses parts of the immune system. Live vaccines are generally avoided while you’re on it, and the “wait time” depends on whether the vaccine is truly live.

• Live attenuated flu vaccine (the nasal spray flu vaccine, e.g., FluMist):
  Most guidelines recommend you do not give live vaccines during secukinumab therapy and for a period after stopping it. In practice, clinicians often use a conservative interval of at least ~12 weeks (about 3 months) after the last dose before giving a live vaccine, because secukinumab has a relatively long time to clear from the body (half-life is on the order of a few weeks).

• Inactivated flu vaccine (the standard flu shot):
  No special waiting period is usually needed—it’s typically considered safe to give while on Cosentyx.

Important: If you tell me (1) which flu vaccine you mean—nasal (live) vs shot (inactivated)—and (2) when your last Cosentyx dose was (and your dosing schedule), I can help you estimate the timing more precisely. Also, your prescribing doctor or pharmacist should confirm, since recommendations can vary by country and your specific health situation.
