Resumo
Fluorouracil causes myelosuppression and immunosuppression, so a live oral adenovirus vaccine may replicate excessively and cause disease. The vaccine response may also be blunted.
O que esta interação significa em palavras simples
Adenovirus types 4 and 7 live and Fluorouracil 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.
Por que acontece
Cytotoxic immunosuppression impairs control of live-attenuated virus and reduces vaccine immunogenicity.

Do not give the live vaccine during chemotherapy; defer vaccination until at least about 3 months after chemotherapy ends and immune recovery is confirmed.
