Why is it necessary to vaccinate a newborn against viral Hepatitis B even if the family members do not have the disease?

Because of Hepatitis B virus (HBV) ability to cause infection without obvious symptoms, many people infected with HBV do not even know they are infected.
In children, if they contract HBV at a very young age, the disease is severe and often fatal.
For this reason, the HBV vaccine is recommended for newborns because the benefits of the vaccine clearly and unequivocally outweigh the risks.
