Can Cosentyx (secukinumab) make vaccines less effective?
Cosentyx (secukinumab) blocks interleukin-17A (IL-17A). Because IL-17A helps coordinate immune responses in the body, patients often ask whether taking Cosentyx can blunt the immune response to vaccines. The key practical point is that vaccine effectiveness depends on the type of vaccine and how the immune system responds under IL-17A blockade.
Which vaccines are generally preferred while on Cosentyx?
Cosentyx is commonly treated as an immunomodulating therapy, so clinicians typically steer patients toward vaccines that are not live. In general practice, non-live (inactivated or recombinant) vaccines are the usual choice when immunomodulatory medicines are involved, because live vaccines carry higher risk of infection in people with altered immune function.
What about live vaccines?
Live vaccines are more concerning for people on immune-modifying drugs because they contain weakened organisms that rely on a competent immune system to stay controlled. As a result, live vaccines are often avoided or used only under specialist guidance with specific timing around treatment. The safest approach is to check the exact vaccine type and confirm with the prescriber before vaccination.
Does timing matter for vaccine response?
Yes. Even when vaccines are considered safe with Cosentyx, clinicians often coordinate timing to improve the chance of a good immune response and reduce safety risks. If you are planning vaccination (for example, before travel or before starting therapy), discussing timing with your rheumatologist/dermatologist and the vaccination provider is important.
What should patients do before getting vaccinated?
Tell the vaccination provider you take Cosentyx and ask:
- Whether the specific vaccine is live or non-live.
- Whether any dose timing adjustments are recommended for your schedule.
- Whether you should be evaluated for any additional vaccine needs (for example, seasonal or routine immunizations).

No source links were provided with your question, and I did not receive any specific Cosentyx-vaccine guidance to cite. If you share the country you’re in (guidance can vary) or the specific vaccine you’re asking about (flu shot, COVID-19, shingles, etc.), I can tailor the answer to that vaccine and map it to the relevant recommendations.
