So the risk you're taking is either it doesn't work or it needs to be modified, in which case you've got six hundred thousand doses you can't use.

Correct.

But the speed premium means you're happy to spend a bit more money, some of which you might end up not getting the advantage of, because speed is the most valuable commodity at a time like this.

And it's worth remembering with this outbreak that this is already the third largest Ebola outbreak we have ever seen, but it's also the most significant in numbers at this stage.

The two largest previous outbreaks in West Africa and the DRC at this point only had five hundred cases.

As of the twenty-seventh, there were three thousand two hundred and sixty-two cases, and there's a case fatality rate of forty-four percent.

Now, if we can deliver anything like a hundred days on getting to a trial or indeed widespread rollout of a vaccine, that would be a huge success.

Uh, how are they going?

And it's worth remembering with this outbreak that this is already the third-largest Ebola outbreak we have ever seen, but it's also the most significant in numbers at this stage.

The two largest previous outbreaks in West Africa and the DRC at this point only had 500 cases.

As of the 27th, there were 3,262 cases, and there's a case fatality rate of 44%.

Now, if we can deliver anything like 100 days on getting to a trial or indeed widespread rollout of a vaccine, that would be a huge success.

Uh, how are they going?

How does that differ from the others, and does that have extra complications?

It certainly does.

So Ebola, I think people have heard of it.

They probably don't know exactly what it is.

Uh, but basically it's a nasty hemorrhagic fever, and it can be caused by a number of different types of this particular virus in this group.

Now, we do have vaccines, and, uh, that's really important for the most common of these.

Sadly, this particular variant, we do not have an approved vaccine, and that of course means it's difficult to control in the first place because of infection control.

... declaration mean?
