Vaccination should be delayed in infants with a birth weight under 2,000 grams if the mother was immune to Hepatitis B (HBsAg negative) when the baby is born.

It should be followed with a full 3-dose standard regimen, for a total of four doses of Hepatitis B vaccine.

    I was diagnosed as HEPATITIS B carrier after tests were done to investigate fatigue. I had chronic hepatitis b with fibrosis of the liver already present. I started Lamivudine (Epivir-HBV) treatment which reduced the viral load initially. After a couple of years the virus became resistant and i decided to try a more natural approach to treat the virus, so i started on HEPATITIS B Herbal formula treatment from RICH HERBS FOUNDATION, this natural HBV treatment totally reversed my condition. I did another blood test after the 4 months treatment and tested negative to the virus.
