Years ago I read a book about a disease that plagued the US. Some benevolent guy came up with a 'free' vaccine that cured everyone. He was a hero.

A year later it was learned the vaccine only had a life expectancy of one year and after that the inoculated would die unless they received an annual 'booster'. The annual shot was expensive and the company made a killing.

I can't remember the title to the book but I sure see some parallels here - Gibbs rule #39, There is no such thing as a coincidence.
