Hi. I have a pet dog at home who happened to attack a little bit on my brother. My brother ended up having a few scratches on the skin. My dog is vaccinated. The issue here is that this incident happened a few months ago (approx 6 months). We got a bit delayed with the vaccination but then later consulted a doctor to check if we need to get him vaccinated against rabies. The doctor mentioned that since it's been a while and my brother has taken a covid shot, it's not needed anymore. Kind of worried as the thought crosses by. What should be done? Should he take a course of rabies now or is it okay?
