You do not need to give your infant the Hepatitis B vaccine at birth.
The hepatitis B shot is routinely given to infants before being discharged from the hospital at 24-48 hours old. Unless the mother or a close household contact has Hepatitis B, your infant has very minimal risk for contracting the virus. You can complete the 3 dose series when they are older if you choose. If a newborn gets their first vaccine in the hospital, it is not uncommon to get an unnecessary 4th Hepatitis B shot because of combination vaccines routinely given at their well visits in the first 6 months of life.
