Hi I Am Just Wondering, My Dog Had His Anti

Hi I am just wondering, my dog had his anti rabies shot last March 9,2015 and It should be done yearly right? 2 days ago while I was feeding my dog his teeth lightly scratched my finger. It did bleed but not much. And now the wound seems to be dry already. My dog seems to be fine he doesnt show any signs pf rabies. He is also 13yrs old. Will I be infected?
