Summary
Sarilumab suppresses immune function, so the live attenuated zoster virus may replicate and cause disseminated vaccine-strain infection. Vaccine response may also be diminished.
What this interaction means in plain words
Sarilumab and Zoster vaccine live can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Immunosuppression from IL-6 receptor blockade impairs control of replicating live attenuated virus.
What to do
Avoid live zoster vaccine during sarilumab therapy. Vaccinate before starting treatment, following current guidance on the interval, or use the recombinant non-live zoster vaccine.
