The correct answer is A. “Yes, you need to get vaccinated because HBV can be transmitted from mother to child during pregnancy or delivery.” This statement is correct because HBV is a blood-borne virus that can infect the fetus through the placenta or during birth. Vaccination can prevent HBV infection and its complications, such as chronic liver disease or cancer.

Statement B is wrong because HBV is a serious disease that affects the liver and can cause inflammation, scarring, cirrhosis, or failure.

Statement C is wrong because although HBV can cause chronic liver disease or cancer in later life, this is not the main reason for vaccination during pregnancy. The main reason is to prevent transmission to the baby.

Statement D is wrong because HBV is not only spread through contact with infected blood or body fluids, but also through sexual contact, sharing needles, or from mother to child.

Normal ranges for HBV tests are:

• HBsAg (hepatitis B surface antigen): negative

• Anti-HBs (antibody to hepatitis B surface antigen): positive after vaccination

• Anti-HBc (antibody to hepatitis B core antigen): negative

• HBeAg (hepatitis B e antigen): negative

• Anti-HBe (antibody to hepatitis B e antigen): positive after recovery

• HBV DNA: undetectable
