Are live vaccines safe post cosentyx use?

Are live vaccines safe after stopping Cosentyx?

Cosentyx blocks a protein involved in immune signaling and can leave the immune system more open to infection for a period after stopping the drug. Live vaccines contain weakened forms of viruses or bacteria that can pose a risk to anyone with weakened immunity.

Why do doctors advise waiting before live vaccines?

Most prescribing information recommends waiting at least 12 weeks after the last dose of Cosentyx before considering live vaccines. This gap is chosen to allow the immune system enough time to recover from the effects of interleukin-17A blockade. Doctors weigh the risk of returning disease activity against the risk of infection from the live vaccine strain.

What happens if a live vaccine is given too soon?

Early administration may lead to vaccine-derived infection because the weakened virus or bacterium can replicate more freely in an immune system that has not fully recovered. In rare cases, this has shown up as disseminated infection or persistent infection in patients on similar biologic therapies.
