The point is Novartis spent nearly $1Billion on this technology.
Dramatically more than the pittance the US government is proposing and we
keep drooling over.  Let's face it.  If you want anything done, the
government is not the place to look.

Janet, more on Novartis and gene therapy. How much time do drug companies
spend
on developing drugs before they throw in the towel?  Really strange, it
seems to
me that it would take a lot of time. Love, Mother
