Previously vaccinated against rabies, it is likely that you are still within the protection period of these rabies vaccines. If the time period is relatively short, a second bite can be given without vaccination. However, this time is set relatively short, set within six months. Like the rabies vaccine instructions or the pharmacopoeia, if you are bitten again during this period, if you still bear the risk of being infected, it is actually recommended that you get a booster rabies vaccination, and the number of booster shots is recommended to be two. However, according to other sources, this time can be left uninjected. If it has been more than six months since the rabies vaccination, within three years, a booster rabies vaccination is required at this time, with a booster of two shots and a booster of three shots within a period of 1-3 years. If more than three years have elapsed, the rabies vaccine will have lost its effectiveness, so a full rabies vaccination is recommended at this time.
