Can Cosentyx (secukinumab) cause adverse reactions to MMR?
Yes. Cosentyx (secukinumab) can be associated with adverse reactions, and those reactions may occur in people who have also received vaccines such as the MMR (measles, mumps, rubella) vaccine. However, the available information in this context does not establish that Cosentyx specifically causes adverse reactions to MMR or that MMR vaccination interacts with Cosentyx in a predictable way.
What kinds of reactions are typically seen with Cosentyx around the time of other immunizations?
Cosentyx’s safety profile includes common immune-related and infection-related effects. Reported adverse reactions for Cosentyx in general may include infections and other side effects, which could be mistaken for or overlap with symptoms that sometimes occur after vaccination (such as mild fever or feeling unwell).
Because symptoms after vaccination can overlap with side effects from immune-modulating medications, an “adverse reaction to MMR” may actually be:
- a reaction to the vaccine itself, or
- an infection or side effect related to Cosentyx, occurring at the same time, or
- a delayed or coincidental event.
Is MMR safe to get while on Cosentyx?
A key point is that MMR is a live attenuated vaccine. For people taking immune-modulating therapies, clinicians often weigh risks before using live vaccines. Whether MMR is recommended depends on the patient’s condition, dosing, and overall immune status. This means the safety decision is individualized and should be confirmed with the prescribing clinician.
What should you do if symptoms happen after MMR while taking Cosentyx?
If you (or a child you’re caring for) develop concerning symptoms after MMR—especially fever that is high or persistent, breathing problems, rash with swelling, or signs of a serious infection—seek medical care promptly. Tell the clinician the exact medication dose and timing of the MMR shot.
Where to check the most specific safety information
For prescribing details, including adverse reactions and warnings, the most reliable starting point is the approved labeling.

Quick clarification question (to give a more precise answer)
Are you asking about:
1) someone taking Cosentyx receiving the MMR vaccine and then developing symptoms, or
2) whether Cosentyx can directly cause an MMR-related antibody or “vaccine reaction” effect?
If you share which situation you mean (and the timing between the Cosentyx dose and the MMR shot), I can narrow the likely causes and what to look for.
