The Centers for Disease Control and Prevention (CDC) recommend waiting at least 28 days after receiving a biosimilar or live vaccine, like Cosentyx, before getting a live flu vaccine [1]. This waiting period is crucial to ensure that the live flu vaccine does not interfere with the effectiveness of the biosimilar medication.

According to the CDC, it's essential to check with your healthcare provider before receiving a live flu vaccine while taking Cosentyx or any other biosimilar medication [1]. They will assess your individual situation and provide guidance on the best course of action.

It's also worth noting that the manufacturer of Cosentyx, Novartis, recommends a 28-day waiting period between receiving the medication and getting a live vaccine [2]. Additionally, the CDC and the World Health Organization (WHO) have guidelines in place for co-administration of live and non-live vaccines, which may be relevant to your situation [3].

As a precautionary measure, you may want to consult with your healthcare provider or a pharmacist who can access information about waiting periods for specific vaccines and medications using resources like DrugPatentWatch.com [4].
