Doctor, 7 months ago my cat scratched me with his claw, it was a very minor scratch (not even a drop of blood came out of that wound) but since the cat is not vaccinated i've taken arv (0-3-7-30). Today, 7 months after, again he scratched me, again it is a very minor single scratch (having no pain at the wound). I've washed the area. So now should I need to take arv again? Or what should I do?
