The complete sequence of the 1918 virus, demonstrating its avian origin, and focusing on those mutations that differentiate avian from human strains will be immensely helpful as we try to understand the factors that govern the epidemic behavior of the current crop of avian H5 viruses.

The urgency around this issue kind of dissipated. I think it's an example of how unpredictable things are. We got distracted.

It's called a neutralization test, and it generally reflects the presence of antibodies that can attach to the bird-flu virus and immobilize it.

It's a difficult drug to use properly. People who hoard the drug might use it improperly or store it improperly, so it won't work. Hoarding is a panic thing.

It's just a preliminary result, but it's very encouraging.

We don't understand exactly why such high dosage is required. But this is a problem that needs to be solved in order to be prepared for a possible pandemic.

There is not a smoking gun. What we're seeing is that all the individual genes contribute, but there is no single gene in there that is sufficient to make that virus a killer.

This trial provided confirmatory evidence of something we already suspected: that age has an effect on immune response.

We realize that sometimes they're going to be very discouraged, but we hope that our presence and our indicating the help that's available to them will lift their spirits.

I don't know that we have any certainty about what's going to happen in the future.
