Summary
Dengue vaccine is live attenuated, and cytotoxic chemotherapy may allow uncontrolled vaccine virus replication while also reducing vaccine response.
What this interaction means in plain words
Dactinomycin and Dengue vaccine 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
Chemotherapy-induced immunosuppression impairs vaccine response and permits live virus replication.
What to do
Avoid live vaccines during chemotherapy and defer until immune recovery per local guidance.
What to ask your pharmacist
