first of all if no bite very less likely to have rabies.. secondly if no vaccine taken that time then thinking of taking it now won't help as it has to be taken within 48 hours only.
so for now please be rest assured if no symptoms till now..it is very less likely that you will ever have rabies now.
Next Steps
relax and forget about rabies.
Health Tips
be safe and next time get vaccination done in time.
