If the titer is lower than 10miu/ml, it is necessary to complete the injecting injection within half a year. If soThe antibody titration is above 10miu/ml, and the vaccine will be vaccinated again within 6 years, so that the patients hepatitis B surface antibody is transformed into positive.
In addition, In order to make the vaccine better effect, everyone should pay attention to the following 4 points when vaccination.
