This is Jane Pauley.

Violin virtuoso, Izzak Perlman contracted polio when he was just four, and has had to use crutches every day since.

Now 80, he shares thoughts about a possible resurgence of the disease with Sunday mornings, Dr. John Lepouk.

So I had to hold you when I was four, around four.

In 1949.

Yeah.

So the first vaccine was given in 1955.

You missed it by about six years.

Yeah, yeah.

So I'm here to tell you that that's what happens when you're not vaccinated.

Describe the emotion that you're feeling when you're talking to me about this right now.

Well, the emotion is that,

you know, I mean, I am a product of the pre-Polio vaccine. So now, I've done pretty well with my life.

But why, you know, you know, why fool around with that?

You know, there's a saying, if it's not broken, why fix it?

So I'm a perfect example of somebody that has spent all of his life to basically

adjust to my disability.

I have to think all the time as to what is accessible.

I just went right now to a place, I had to take some photos,

and there was a step that high.

And I couldn't get in.

So they said, oh, we can do it. And so they bring a very short ramp to put on the stair when I had to go with my scooter.
