Tamiflu is oseltamivir. CDC has info on antivirals and vaccines for H5N1 and H7N9.
Tl;dr: we have 3 antivirals, but some evidence of resistance, and a small stockpile of candidate vaccines, though the virus mutates fast.
Antiviral Drugs Can Be Used to Treat Illness
CDC currently recommends treatment with a neuraminidase inhibitor for human infection with avian influenza A viruses. Analyses of available avian influenza viruses circulating worldwide suggest that most viruses are susceptible to oseltamivir, peramivir, and zanamivir. However, some evidence of antiviral resistance has been reported in HPAI Asian lineage avian influenza A(H5N1) viruses (“Asian H5N1 viruses”) and Asian lineage avian influenza A(H7N9) viruses (“Asian H7N9 viruses”). Monitoring for antiviral resistance among avian influenza A viruses is crucial and ongoing.
U.S. Government Stockpiling Asian H5N1 and Asian H7N9 Vaccines If Needed
The United States federal government maintains a stockpile – vaccines, including vaccine against Asian H5N1 and Asian H7N9 viruses. The stockpiled vaccines could be used if similar viruses were to begin transmitting easily from person to person. Since influenza viruses change, CDC continues to make candidate vaccine viruses as needed. Creating a candidate vaccine virus is the first step in producing a vaccine. More information about “Making a candidate Vaccine Virus (CVV) for a Highly Pathogenic Avian Influenza (Bird Flu) Virus” is available.
