How long did rabies vaccine last?

How long rabies vaccine lasts after five doses varies from person to person. To know how long it lasts, regular monitoring of rabies neutralizing antibodies is required. However, in the absence of rabies neutralizing antibodies, it lasts for 1-3 years for most people. However, within six months to one year after rabies vaccine injection, the corresponding effect may show a decline. Therefore, it is generally recommended that if you are bitten again at this time, you need to strengthen the injection of two doses of rabies vaccine. If you are bitten again within 1-3 years, you need to strengthen the injection of three doses of rabies vaccine. During this period, although rabies vaccine needs to be strengthened, it does not need to be completely injected five doses. Therefore, rabies vaccine can still play a certain role within this time. However, rabies vaccination is required after more than three years, so the duration of rabies vaccination will not exceed three years for most people.
