Saikou is correct - herpes is for life (although around 45% of infected cats never shed the virus again after their initial infection) and calici can be eliminated by the majority of cats - although they can be reinfected at a later date. A minority do become lifelong carriers, but they're not necessarily going to infect every other cat they come in contact with.
There is an excellent information sheet on cat flu on the FAB website.
