Harry Immortal?

I've read Order of the Phoenix again, and I have a new problem with 
the prophecy. If Harry must kill Voldemort or be killed by him, then 
isn't he invulnerable until that happens?

To put it another way, if I knew with certainty that I was going to 
develop a cure for cancer or die from cancer, why couldn't I jump off 
the roof for fun? The fall wouldn't do me in unless I'd already rid 
the world of the disease, right?

Go ahead and let me know if I'm off base.
