Can you get live vaccines while taking Cosentyx (secukinumab)?
Cosentyx (secukinumab) is a treatment that blocks interleukin-17A (IL-17A). Because it can change how your immune system responds, people taking Cosentyx are generally advised to avoid live vaccines unless their clinician specifically says it’s safe for them. The main concern is that live vaccines contain a weakened form of a germ that could cause infection in someone whose immune defenses are suppressed.
What vaccines count as “live”?
Live vaccines include certain formulations such as:
- MMR (measles, mumps, rubella)
- Varicella (chickenpox)
- Zoster live vaccine (the older shingles vaccine formulation)
- Live nasal spray influenza vaccine
If you’re unsure whether a vaccine is live, ask the prescriber or the clinic giving the shot to confirm the vaccine type before you schedule it.
What if a live vaccine was given before starting Cosentyx?
If you received a live vaccine shortly before starting Cosentyx, tell your prescribing clinician. They can decide whether any monitoring or timing adjustments are needed based on your dose schedule and your overall risk factors.
Are non-live vaccines okay on Cosentyx?
Inactivated vaccines and other non-live vaccine types are usually considered safer than live vaccines for people on biologic therapies like Cosentyx. These may still be less effective than usual in some patients, but they’re commonly used when protection is needed (for example, flu and COVID-19 vaccines).
Who is at higher risk and needs extra caution?
Clinicians may be more cautious about vaccines in people with:
- Higher-risk infections or a history of recurrent infections
- Concurrent immunosuppressive medicines (for example, corticosteroids or other biologics)
- Significant immune system problems beyond Cosentyx alone
Your vaccination plan should be individualized.
What should you do before traveling or during flu/COVID season?
If you’re planning travel, work-required immunizations, or vaccines for outbreaks:
1. Check whether the vaccine is live.
2. Coordinate timing with the clinician managing Cosentyx.
3. Ask whether you should receive the vaccine before starting treatment, if you’re not yet on Cosentyx.
If you tell me which live vaccine you’re considering (and whether you’re currently taking Cosentyx, your dose, and how often), I can help you map out the usual decision points to bring to your doctor.
