Summary
Systemic corticosteroid exposure can blunt the antibody response to inactivated vaccines, so protection may be lower than expected. With the topical dexamethasone-tobramycin combination, systemic absorption is usually small, so the clinical effect is generally limited.
What this interaction means in plain words
Dexamethasone-tobramycin and Influenza virus vaccine quadrivalent cell-cultured have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Corticosteroid immunosuppression may reduce the immune response to vaccine antigens, but systemic exposure from topical use is low.
