Can you get vaccinated while taking Cosentyx (secukinumab)?
Cosentyx (secukinumab) is an immunosuppressive biologic used for inflammatory conditions such as psoriasis, psoriatic arthritis, and ankylosing spondylitis. Because it affects immune signaling, the key safety issue is whether a vaccine is “live” or “non-live.”
In general, patients on biologics like Cosentyx are typically advised to:
- Use non-live vaccines when possible (these are generally considered safe).
- Avoid live vaccines unless your clinician specifically confirms it’s appropriate for your situation.
This is the main practical rule doctors follow when deciding vaccine timing with Cosentyx.
Are “live” vaccines safe during Cosentyx?
Live vaccines contain a weakened form of the virus or bacteria. For people taking immune-modifying drugs, live vaccines are usually avoided due to the risk that the vaccine could cause infection because the immune response is altered.
Common examples of live vaccines include (this varies by country/age group), such as:
- MMR (measles, mumps, rubella)
- Varicella (chickenpox)
- Live attenuated influenza (nasal spray)
Whether you can ever receive these while on Cosentyx depends on your prescriber’s assessment (your diagnosis, dose, other immune effects, and how long you’ve been treated).
Are flu, COVID-19, and other routine vaccines safe with Cosentyx?
Non-live vaccines are generally considered safe for people taking Cosentyx. That typically includes:
- Seasonal flu shot (injection, not the nasal live spray)
- COVID-19 vaccines (authorized formulations are not live vaccines)
- Tdap/Td (tetanus, diphtheria, pertussis)
- Many others used in routine adult schedules that are not live preparations
Even when vaccines are safe, immune response can sometimes be weaker with immunosuppressive therapy, so your clinician may suggest timing or confirm you’re up to date.
When should you get vaccinated relative to starting Cosentyx?
A common strategy is to update vaccines before starting immunosuppressive therapy, when feasible. If you already take Cosentyx, your clinician may still recommend vaccination but often chooses a schedule that minimizes risk (especially for anything potentially live) and lets the vaccine be effective.
For live vaccines in particular, doctors typically require a waiting period after stopping immunosuppressive treatment before giving the vaccine and may restart Cosentyx afterward based on clinical judgment.
What should you tell your doctor before getting a vaccine?
Before vaccination, share:
- You take Cosentyx (and your dose and schedule)
- Any history of serious infections
- Your plan for travel or a specific vaccine you’re considering
- Whether the vaccine is live or non-live (your pharmacy/clinic can tell you)
If you want, tell me which vaccine you’re planning (name and whether it’s an injection vs nasal, if relevant), and I can help you identify whether it’s typically considered live or non-live and what clinicians usually do with Cosentyx.
What are the risks or red flags after vaccination?
Most vaccination side effects are expected and are not specific to Cosentyx (sore arm, mild fever, fatigue). Seek urgent medical care if you develop:
- High fever that doesn’t settle
- Signs of a serious allergic reaction (difficulty breathing, swelling of face/lips, hives spreading)
- Severe or worsening symptoms, especially if you also have signs of infection
Does Cosentyx change how well vaccines work?
It can. Because Cosentyx modifies immune pathways, vaccine effectiveness may be reduced compared with someone not taking immunosuppressive therapy. That doesn’t necessarily mean vaccination is unsafe—it usually means you may need to be especially careful to stay up to date, and your clinician may discuss timing.
Can I get vaccinated if I’m on Cosentyx but also taking other immune medicines?
Yes, but decisions become more individualized. If you also take steroids, methotrexate, other biologics, or have other immune conditions, your prescriber may be more restrictive about live vaccines and may adjust timing.
If you list all immune-related medications you take (including doses), I can help you map the likely vaccine-safety approach.
