Based on the available information, there is no specific timeframe provided regarding how long after stopping Cosentyx (secukinumab) one should wait before taking live vaccines. Cosentyx is a biologic medication used to treat various conditions such as plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis [1][2].

The Cosentyx website does mention that "you may receive vaccinations, except for live vaccines, while taking COSENTYX" [3]. However, it does not provide information on the timeframe after stopping Cosentyx for live vaccine administration.

It is generally recommended to discuss any vaccinations or changes to medication schedules with a healthcare provider, as they can provide the most accurate and personalized advice based on individual medical history and current health status [2].

In summary, based on the provided sources, there is no clear answer to how long after stopping Cosentyx one should wait before taking live vaccines. It is best to consult with a healthcare provider for personalized advice.
