The rabies vaccine is not 100% effective in preventing rabies, but it can significantly reduce the probability of infection.
First of all, each person’s physical condition is different, the reaction to the rabies vaccine is also different, some people after the injection of rabies vaccine is not able to produce protective antibodies, which will reduce the role of protection.
Secondly, some people do not get the rabies vaccine until a long time after the exposure, which also reduces the preventive effect of the rabies vaccine, so it is recommended to get the vaccine as soon as possible within 24 hours after the high-risk exposure.
Factors affecting the role of rabies vaccine is relatively complex, and rabies vaccine antibody production is relatively slow, so the injection of rabies vaccine can not be 100% on the prevention of rabies, so if there are bleeding wounds should be injected with rabies vaccine as well as rabies immune globulin, so that a better prevention.
