Summary
Dengue vaccine is a live attenuated vaccine, and capecitabine-induced immunosuppression may both reduce the immune response and increase the risk of vaccine-related infection. Vaccination during chemotherapy is generally inappropriate.
What this interaction means in plain words
Capecitabine 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
Cytotoxic immunosuppression impairs response to the vaccine and permits replication of live attenuated virus.
What to do
Avoid live vaccines during chemotherapy and give them only after immune recovery as advised by the specialist team.
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?
