Summary
Vincristine-based chemotherapy suppresses immune function and can blunt the antibody response to the H5N1 vaccine. Patients may therefore be inadequately protected.
What this interaction means in plain words
Influenza a vaccine and Vincristine 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 reduces vaccine immune response.
What to do
Where possible, vaccinate before starting chemotherapy or during periods of recovery. Do not rely on the vaccine alone for protection in immunosuppressed patients.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
