Résumé

The intranasal influenza vaccine is live attenuated. Corticosteroid-induced immunosuppression could allow vaccine virus replication and may also reduce the immune response. The risk is greater with higher or prolonged steroid exposure than with replacement-dose fludrocortisone.

Ce que signifie cette interaction, en termes simples

Fludrocortisone and Influenza virus vaccine quadrivalent intranasal 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.

Niveau de preuve: Moderate

Pourquoi elle survient

Corticosteroid immunosuppression reduces control of live attenuated virus and blunts vaccine immunogenicity.

Conduite à tenir

Use an inactivated influenza vaccine instead in patients on systemic corticosteroids. Give the live intranasal vaccine only after specialist review and when steroid exposure is non-immunosuppressive.
