After the hepatitis B vaccine booster injection, blood can be drawn two to three months to check the number of antibody drops; if the number of hepatitis B antibody drops is greater than 10mIU/mL, it is protective; if the number of hepatitis B antibody drops is greater than 100mIU/mL, it indicates strong protection; if the number of hepatitis B antibody drops is less than 10mIU/mL, it is necessary to re-inject hepatitis B vaccine.
