Having had a rabies vaccine before and now having been bitten by a cat, you need to look at the time interval between now and the last injection of the rabies vaccine. First of all, the wound should be treated, with flowing water as well as soapy water to do the rinsing, rinsing time as much as possible in more than 15 minutes. You can also use iodophor to disinfect, alcohol can also be, but alcohol in the case of more obvious wounds, it is likely to be more painful, you can also go directly to the hospital for treatment. Regarding whether or not to get a rabies vaccine, it depends on how long it has been since the rabies vaccine was given, and if it is within six months, a rabies vaccine is most likely not needed. The recommendations related to this are not exactly the same in some sources, but the more authoritative recommendation suggests that another rabies vaccination is not needed within six months. Two booster shots can be given at six months to a year, on days 0 and 3. If it’s between one and three years, three booster shots can be given, on days 0, 3 and 7. If it is more than three years, this is when the full rabies vaccine is needed. Because of the previous rabies vaccination, the use of rabies serum or immune globulin is not highly recommended in the case of a second bite.
