Live varicella vaccine can cause disseminated vaccine-strain varicella in patients taking sirolimus, and the immune response may be reduced. Live vaccines are generally avoided during immunosuppression.
What this interaction means in plain words
Sirolimus and Varicella virus 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
Sirolimus impairs lymphocyte-mediated control of live attenuated virus and blunts vaccine response.
What to do
Avoid live varicella vaccine during sirolimus therapy; vaccinate before transplant when possible. Consider the recombinant non-live zoster vaccine for older patients.
