I thought it was already reported that Tamiflu was ineffective, so far, when tested against the current strains of H51N?
As as far as a vaccine, I know I read that until it mutates to a person/person strain, there's no point in making a vaccine.
From the CDC web site:
Antiviral Agents for Influenza
Four different influenza antiviral drugs (amantadine, rimantadine, oseltamivir, and zanamivir) are approved by the U.S. Food and Drug Administration (FDA) for the treatment and/or prophylaxis of influenza. All four have activity against influenza A viruses. However, sometimes influenza strains can become resistant to these drugs, and therefore the drugs may not always be effective. For example, analyses of some of the 2004 H5N1 viruses isolated from poultry and humans in Asia have shown that the viruses are resistant to two of the medications (amantadine and rimantadine). Monitoring of avian viruses for resistance to influenza antiviral medications is ongoing.
According to this Tamiflu and Relenzea both seem to work against this strain.
