Summary
Chlorambucil is a myelosuppressive alkylating agent that impairs lymphocyte function and can blunt the antibody response to influenza vaccination. The patient may be left with inadequate protection despite being vaccinated.
What this interaction means in plain words
Chlorambucil and Influenza virus vaccine trivalent adjuvanted 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
Pharmacodynamic antagonism: cytotoxic suppression of B and T lymphocyte responses reduces vaccine immunogenicity.
What to do
Inactivated influenza vaccine is still generally recommended; where possible give it before starting chemotherapy or between cycles. Do not rely on the vaccine alone and reinforce infection precautions.
