She had a spina bifida defect, a spinal cord abnormality.

Within a couple of years, every country that started polio eradication rapidly eradicated all three of their polio viruses, with the exception of four countries that you see here.

A vertebrae.

This is a bowhead whale.

This is a volcanic ridge.

We make maps of these mountain ranges with sound, with sonar, and this is one of those mountain ranges.

It'll break her backbone right away.

This is a polio vaccine.

Fire one more round, then let's get the hell off this ridge.

In the spinal ward, that's normal.

Take both machine guns. Set one up to hold that ridge.

A fractured spine?

And same thing for invertebrates. This is the example.

This was not the first synthetic virus a polio virus had been made a year before but it was only one ten thousandth as active and it took three years to do.

There were chills up my spine

This is a view taken along the summit ridge.

This is a picture that shows the tail of a right whale.

This is what a real one looks like, on the Juan de Fuca Ridge.

OK, this is a view taken on the summit ridge itself.

This sent shivers up my spine.

I have no other world, no other life.

Crossing miles and miles of sastrugi frozen ice snowdrifts that could be hip deep.

The one

Umar also has polio.

Chills run up and down my spine.

I'll play the sound of a contact call used by right whales to stay in touch.

My spine curves spiral.

Bugle. Chinese. Up on the ridge.

Here's the Sierra Magdalena.

Finishing polio eradication is the right thing to do.

Jordy, you're the one with a responsibility to Reata.

This is the polio virus.

And so here's the front and the spine, and it's flat.

The climbers got on the southeast ridge.

It makes the backs of me legs go funny. Height always did.

Looks a little higher up on that ridge.

More myself was the backbone, of course.

You are the only one qualified. The only one we can possibly send.

Unique ID

Unique Constraint...

Livers and internal organs sort of take a bit longer. A spine takes several years.

Todd and Pete got up to the summit ridge, up in here, and it was a scene of complete chaos up there.
