Based on the information available, there is no definitive recommended wait time for the Measles, Mumps, and Rubella (MMR) vaccine after taking Cosentyx (secukinumab) [1]. However, it is important to note that Cosentyx, a medication used to treat several autoimmune diseases, can affect the immune system's response to vaccines [2].

The Prescribing Information for Cosentyx states that "live vaccines should be administered at least 4 weeks prior to initiation of Cosentyx therapy" [3]. This suggests that if a patient is due for an MMR vaccine, it should be given before starting Cosentyx if possible.

In terms of receiving the MMR vaccine after Cosentyx, the manufacturer of Cosentyx, Novartis, states that "the immune response to any vaccine, including vaccines for active immunization against infectious diseases, may be reduced" [3]. Therefore, it would be advisable to discuss with a healthcare provider when the MMR vaccine can be safely administered after discontinuing Cosentyx.

In conclusion, while there is no specific recommended wait time for the MMR vaccine after Cosentyx, it is important to consult with a healthcare provider to determine the best course of action.
