Based on the information provided, there is no specific guidance on how long before receiving a vaccine one should stop taking Cosentyx (secukinumab). Cosentyx is a medication used to treat various conditions such as plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis [1][2].

The Cosentyx COVID-19 resource page does not mention any specific instructions regarding vaccine administration [3]. The Consumer Medicine Information leaflet for Cosentyx in New Zealand also does not provide information on this topic [4].

However, it is generally recommended to inform your healthcare provider of all medications you are taking before receiving a vaccine [5]. This will allow them to consider any potential interactions or precautions that may be necessary.

In summary, there is no specific information available on how long before vaccines one should stop taking Cosentyx. It is always best to consult with a healthcare provider for personalized advice.
