About Hepatitis B Vaccines Hepatitis B is an inflammatory condition that occurs due to infection by hepatitis B virus. Hepatitis B virus is an enveloped virus that belongs to the family of hepadnavirus. It contains a circular genome with partially double-stranded DNA. The virus interferes with the normal functioning of the liver cells. Following the viral infection, the immune system is activated against virus and hepatocytes infected with viruses. This, in turn, leads to the inflammation of the liver. Extra-hepatic manifestations of hepatitis B include polyarteritis nodosa, Gianotti-Crosti syndrome, transient serum sickness-like syndrome, and membranous glomerulonephritis.
