Questions

If the mother is a carrier of the Hepatitis B virus, how should the newborn’s Hepatitis B vaccine be administered, and is it necessary to increase the dosage?

Answers

  1. The dosage of the Hepatitis B vaccine depends on the type of vaccine. Domestic vaccines usually have a higher dosage, while imported vaccines have a lower dosage. The 20 microgram dose administered at birth is already doubled, and the third dose only requires 10 micrograms.
  2. The immune globulin administered at birth contains antibodies directly injected into the body to prevent potential infection with the Hepatitis B virus during childbirth.
  3. Theoretically, one dose of the vaccine can produce antibodies, and the antibodies produced during the second dose will increase significantly. Due to individual variations in response, a three-dose regimen is set to ensure safety. After receiving the third dose, the newborn can go home. However, it is important to note that not everyone who receives the vaccine will produce antibodies. It is recommended to check the antibody levels after receiving the third dose. If the antibody titer is high, there is no need to worry.
