Vaccinated cats do not need injections when scratched and bleeding. You only need to rinse the wound, squeeze out the blood, and then apply iodophor for disinfection; because vaccinated cats generally do not carry Rabies is spread through saliva and blood, so cats generally do not have rabies virus on their paws.
Tip:
If you are worried, you can observe the cat for ten days. Rabies is only contagious in the early stage of the disease, and the cat will not be infected after ten days. It's okay if you get sick.
