Based on the available information, the question at hand is whether timing Cosentyx dosage around vaccines is crucial. Cosentyx, also known as secukinumab, is a biologic medication used to treat various conditions, including plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis [1][2]. The Cosentyx treatment dosing information does not specifically mention vaccines or provide guidance on timing doses around vaccinations [2].

However, the Centers for Disease Control and Prevention (CDC) provides general recommendations for vaccinations in relation to immunosuppressive drugs, which could include biologics like Cosentyx [3]. According to the CDC, "Inactivated vaccines can be given without regard to the timing of immunosuppressive therapy. However, the response to these vaccines might be suboptimal" [3]. Live vaccines should be avoided if the patient is immunosuppressed or will be immunosuppressed due to treatment [3].

In conclusion, while the Cosentyx-specific information does not directly address vaccine timing, general guidance from the CDC suggests that inactivated vaccines can be administered without considering the timing of immunosuppressive therapy, but live vaccines should be avoided [3]. Patients should consult their healthcare providers for personalized advice on vaccinations and Cosentyx dosing.
