Summary
Procarbazine-induced immunosuppression may lower the antibody response to Japanese encephalitis vaccine. This matters for patients traveling to endemic areas who may remain unprotected.
What this interaction means in plain words
Japanese encephalitis virus vaccine and Procarbazine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Chemotherapy-induced immunosuppression blunts the humoral response to vaccine antigens.
What to do
Complete vaccination at least 2 weeks before procarbazine when possible; if given during therapy, consider revaccination about 3 months after treatment and check immunity if travel risk is high.
