Need help with vaccination names for cats?

our kittens (6 months) just got fixed, and before they would do the procedure the vet wanted ('wouldent do without' is a better term) to give them the rabies vaccination, and the Fvr-C-P #3 vaccination, i have no idea what this vaccination is, would anyone else know and know wether theyll need to get it again in a year (or whatever)?? i understand if noone knows, but any help would be loved!
