Have you ever been vaccinated against rabies?

Rabies vaccination does not provide lifelong immunity. If you are bitten again after three years of rabies vaccination, you need rabies vaccination. That is to say, after three years, the neutralizing antibodies produced by rabies vaccine will generally drop to a relatively low level, so you need rabies vaccination again. However, within three years, the rabies vaccine previously played still has a certain effect, so within three years, it may not be necessary to re-inject rabies vaccine, it may only need to strengthen the injection, and does not need the whole injection. Therefore, rabies vaccine is not able to make people immune for life, rabies vaccine will make the body produce rabies neutralizing antibodies, the concentration of this neutralizing antibody will gradually decrease over time.
