Sintesi

Dengue vaccine is a live attenuated vaccine. Pemetrexed is a cytotoxic antimetabolite that suppresses immunity, which may reduce the vaccine response and raise the risk of vaccine-related infection.

Cosa significa questa interazione in parole semplici

Dengue vaccine and Pemetrexed 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.

Livello di evidenza: Moderate

Perché avviene

Immunosuppression from cytotoxic chemotherapy blunts vaccine response and permits uncontrolled replication of live attenuated virus.

Cosa fare

Avoid live vaccines during pemetrexed therapy and for a period after recovery of immune function as specified by local guidance. Vaccinate before starting chemotherapy where possible.
