What is the youngest age that the hepatitis B vaccine is recommended for infants and children?

The hepatitis B vaccine is recommended to be administered at birth, making this the earliest point at which infants are protected against this virus. Vaccination against hepatitis B in newborns is crucial because it can prevent the transmission of the virus from an infected mother to her child during the delivery process. Early immunization is essential, as hepatitis B can lead to chronic liver disease and increase the risk of liver cancer later in life.

The vaccination schedule typically includes the first dose of the hepatitis B vaccine within 24 hours of birth, followed by subsequent doses according to the recommended immunization schedule. Starting vaccination at birth ensures that infants are protected as early as possible, significantly reducing the chances of infection and promoting public health measures aimed at controlling hepatitis B transmission.
