Do vaccines still work when you’re taking Cosentyx (secukinumab)?
Cosentyx (secukinumab) is a biologic that blocks interleukin-17A (IL‑17A). Because it can dampen parts of the immune response, vaccines may work less well than they do in people who are not on immunosuppressive therapy, depending on the type of vaccine and the timing of doses. In practice, clinicians focus on using vaccines that are considered safe with biologics and giving them when the immune response is expected to be strongest.
What kinds of vaccines are generally recommended or avoided on Cosentyx?
Health systems commonly recommend:
- Inactivated (non-live) vaccines: usually considered safe for people on biologic therapies like Cosentyx.
- Live vaccines: often avoided while on therapy with biologics, because the immune response could be insufficient and there is a theoretical risk of infection from the vaccine strain.
The exact “safe/avoid” determination depends on the specific vaccine and your treatment plan, so your prescribing clinician or pharmacist should confirm for your situation.
How does the timing of vaccination matter on Cosentyx?
For vaccines that need an immune response that is as strong as possible, timing can matter. Many clinicians aim to vaccinate before starting immunomodulatory treatment when feasible, or schedule vaccinations around dosing when the risk-benefit balance is favorable. The goal is to maximize antibody response while still protecting you from infections during treatment.
Will you get enough protection if vaccination is done during Cosentyx?
Vaccination during Cosentyx therapy can still provide protection, especially with inactivated vaccines, but the strength of the immune response may be reduced compared with people not receiving IL‑17A blockade. That means it’s possible to be protected but not to the same degree, which is one reason clinicians may stress staying up to date with recommended vaccines and boosters.
Which vaccines are most important for people on Cosentyx?
Common priorities for immunomodulated patients usually include vaccines that prevent severe respiratory and other infections (for example, seasonal influenza, pneumococcal vaccination, and age- or risk-based vaccines such as shingles). What you need depends on age, prior vaccination history, and comorbidities.
What should patients do before getting vaccinated?
People on Cosentyx typically should:
- Check with their dermatologist/rheumatologist or prescribing clinician about the specific vaccine type (live vs inactivated).
- Review vaccine history and whether boosters are due.
- Tell the vaccine provider you’re taking Cosentyx so they can select the appropriate vaccine formulation.
If you share your age, which vaccines you’re considering (for example, flu, COVID-19, shingles, pneumococcal), and whether you’re already on Cosentyx or planning to start, I can help you narrow down what to ask your clinician.
