Is there any medicine or vaccine that can prevent humans from avian influenza?
Three antiviral drug are licensed in some countries for the prevention of influenza:
Oseltamivir, marketed as Tamiflu®
Amantadine
Rimantadine
Analysis of the viruses isolated from fatal human cases in Vietnam indicates that current H5N1 viruses are resistant to amantadine and rimantidine. The current H5N1 viruses do however appear to be sensitive to oseltamivir.
A vaccine for humans against avian influenza H5N1 is being developed but is still in the experimental stage.
