It worries us, because it is a virus that would theoretically better bind to human cells.

The data indicate the virus is being transmitted efficiently from dog to dog. It is now well established in the dog population.

The previous vaccine we developed was a strain obtained in Vietnam from 2004. The vaccine against the Vietnam virus would not be the most appropriate to protect against the Indonesia-like viruses.

The data indicates that the virus is being transmitted efficiently from dog to dog, and this indicates that the equine virus was transmitted to dogs and is now well established in the dog population.

One was a regular virus like we have seen in poultry in Turkey before.

The risk of that is low, but we are keeping an eye on it.

[This strain of influenza virus] has been in horses for 40 years, and in all these years, we have never been able to document a single case of human infection with the virus.
