As we build up our capacity to respond to seasonal influenza, it will put us in good stead.

It will take years to get stockpiles to the point you can effectively use it at the doses you want.

a sobering finding ... it tells us you still have to worry about this, but you have to worry about something else too, because somehow, somewhere, the virus is coming from a place that we haven't yet identified.

Luckily, those two factors will neutralize each other.

When we can get the incidence of HIV down enough to turn the trajectory of the pandemic, it will assume a momentum of its own in diminishing HIV.

With seasonal flu, the response rate in healthy young adults ranges from 60 to 90 percent. We all hoped for 70 percent with this vaccine, but it wasn't to be. The next step is to give a booster to those who failed to respond, which we're already doing. Earlier studies have shown a third shot often increases immunity dramatically.
