Can you get a flu shot right after Cosentyx (secukinumab)?
Cosentyx (secukinumab) is an immune-modifying biologic that can lower immune responses. Because of that, whether you can take a flu shot immediately after dosing depends on the type of flu vaccine you plan to get.
The usual rule for people on immune-modifying therapy is:
- Avoid live vaccines.
- Use non-live (inactivated or recombinant) vaccines.
For the seasonal flu shot, the standard injectable flu shot used in most settings is not a live vaccine, so it is generally the type that’s compatible with immunosuppressive medications. (Live attenuated flu nasal spray is the one that raises concern.)
What kind of flu vaccine should people on Cosentyx get?
When clinicians talk about flu vaccination for patients on drugs like Cosentyx, they are typically trying to ensure the vaccine is non-live:
- Injectable flu shot (inactivated or recombinant): generally preferred/used.
- Flu nasal spray (live attenuated): generally should be avoided while on immune-modifying therapy.
If you tell the vaccination site your medication name (Cosentyx), they can confirm which flu product you’re being offered.
When should the flu shot be timed relative to your Cosentyx dose?
The question isn’t only whether a flu shot is safe, but also whether delaying it is needed based on your current immune status.
In practice, many patients on stable biologic therapy can receive seasonal influenza vaccination without needing to wait for the next dosing interval, as long as the vaccine is non-live. The key practical decision is usually:
- Don’t delay because of Cosentyx alone unless your prescriber advises it.
- Coordinate with your rheumatology/dermatology/oncology team if you’ve recently had an infection, you’re due for treatment changes, or you have additional immunosuppressive medicines.
What if you recently had an infection or are sick right now?
If you currently have a fever or active infection, vaccination is often postponed until you’re better. This is less about Cosentyx timing specifically and more about avoiding confounding illness symptoms and ensuring you respond well to the vaccine.
If you’re currently ill, ask your prescribing clinician whether to wait.
What side effects or flare-ups should you watch for after vaccination?
People on immunomodulators can still have typical vaccine effects (sore arm, fatigue, mild fever). Watch for:
- Signs of worsening infection.
- Severe allergic symptoms (seek emergency care).
- Any unusual flare of underlying condition.
If you’ve had past vaccine reactions or frequent infections, it’s reasonable to discuss timing and vaccine choice with your prescriber.

Practical answer
Most of the time, you do not need to delay a flu shot after taking Cosentyx if you’re getting the standard non-live injectable flu vaccine. Avoid the live attenuated flu nasal spray, and postpone vaccination if you’re currently sick or have a fever. When in doubt, confirm the vaccine type with the clinic and ask your Cosentyx prescriber.
