Is there anything bad about getting more than the recommended dose of the hepatitis B vaccine?

Patient's question:

What's wrong with getting too many hepatitis B vaccinations? The child has been in this condition for a while, and I'm afraid to give them medicine. Please give me some advice from the doctor.

Doctor's answer:

For newborns whose mothers are hepatitis B carriers, they can receive three doses of hepatitis B vaccine within 24 hours after birth, at one month, and at six months, which can significantly reduce the newborn's infection rate. This is known as the 016 regimen. If, in addition to receiving the hepatitis B vaccine, the newborn also receives three doses of hepatitis B immune globulin according to the 016 regimen, the possibility of the newborn becoming infected with the hepatitis B virus can be almost completely prevented. Generally, getting an extra dose of the hepatitis B vaccine will not cause any adverse effects.
