If you are bitten again within a year after a complete rabies vaccination, it depends on the timing to determine if a booster rabies vaccination is needed. According to some information, if you are bitten again within six months after the rabies vaccination, you do not need a rabies vaccination again. If you have been bitten for more than six months and are within one year, you can get a two-dose rabies booster. According to the pharmacopoeia or the rabies vaccine instructions, any time you are bitten again within a year, you can get a two-dose booster rabies vaccine. Generally speaking, the recommended clinical application is that a second bite within six months does not require a rabies vaccination, while a second bite between six months and one year can be boosted with two rabies vaccinations, one on day 0 and one on day 3.
