It is really important to keep monitoring and watching any changes occurring in your body. These small pink pimples that you see might be due to Herpes. Having sores, blisters, and itching are the common outcomes when you get an infection.

It's great that you finished your vaccination following the first cat scratch. Having a new scratch 5 months later, you do not need to get the vaccine again. As long as you have finished the full course in the past and it is less than a year since then, you are safe. Be on the lookout in case of any flaming, puffing, or fever. If you see these signs, consult your doctor.
