Summary
Dengue vaccine is live attenuated. Pralatrexate is immunosuppressive and may blunt the vaccine response and increase the risk of vaccine-strain infection.
What this interaction means in plain words
Dengue vaccine and Pralatrexate 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 replication of live virus.
What to do
Avoid the live vaccine during pralatrexate therapy and until immune recovery per local guidance. Vaccinate before treatment where possible.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
