In the vaccine area,

Salk vaccine, those who got the treatment, those who got the real vaccine.

This is a polio vaccine.

The vaccine will probably be useless.

Dr. Njoku Obi invented the Cholera vaccine.

And why? Because Paul made a vaccine.

Now giving the polio vaccine is simple.

But there's a vaccine for that too.

You've heard about the vaccine we're stockpiling.

Yes. That plane contained an experimental vaccine.

Major, Trixie wasn't developed as a vaccine.

Jonas Salk developed the polio vaccine in 1952.

The vaccine effort though is really quite different.

And that would create a universal HlV vaccine.

And think of the laptop as a vaccine.

This strategy, working backwards from an antibody to create a vaccine candidate, has never been done before in vaccine research.

But first, let's start with the polio vaccine studies.

There was no cure, and there was no vaccine.

Even then, kids need many doses of the vaccine.

Paul Offit ... Vaccine allowed us to eliminate polio virus.

It probably isn't the perfect vaccine, but it's moving along.

You normally get a trivalent vaccine against three possible strains.

Twenty years later, they succeeded and developed the polio vaccine.

It's a very difficult thing to make a vaccine for.

The new vaccine had twice the impact on these last couple of viruses as the old vaccine had, and we immediately started using this.

For the first time, we saw an AlDS vaccine work in humans albeit, quite modestly and that particular vaccine was made almost a decade ago.

I don't know what's worse than allowing children on this planet to die of vaccine preventable diseases diseases for which the vaccine costs a dollar.

So here's a comparison of several of these new vaccine technologies.

And it's not a pneumonia that would respond to a vaccine.

So in the polio vaccine example we'll cover in a second, it's just whether the child was administered with the vaccine or administered with a placebo.

Until recently, we haven't had to know exactly how a vaccine worked.

Memory cells generated by the HlV vaccine are activated when they learn

Without a vaccine, these responses would have taken more than a week.

He just developed a rotavirus vaccine with a bunch of other people.

A vaccine would be a terrific thing, only they don't work yet.

This green goo is perhaps the vaccine that could save your life.

This green goo is perhaps the vaccine that could save your life.

Sir, the report was that the Trixie team had deactivated the vaccine.

So, the experimenter or the person who's actually administering the vaccine, actually didn't know if they were giving the live vaccine or if they were giving the placebo.

Drugs is too costly had we had the vaccine, or when we will get the vaccine, that's something more effective but the drugs are very costly for the poor.

Hundreds of millions of dollars were spent and flowed to accelerating vaccine manufacturing.

One is a classic, the Salk Vaccine trials to eradicate polio in the

And one was a live vaccine, the other was just a control placebo.

And here's the result of one of the first uh, Salk vaccine trials.

The second challenge we had was in contrast to the smallpox vaccine, which was very stable, and a single dose protected you for life the polio vaccine is incredibly fragile.
