Medical experts say vaccination is the best prevention method for hepatitis B, a liver infection that can be acute or chronic. The disease has no cure and can cause a variety of complications.

While a vote on the hepatitis B vaccine is underway comes a report on a medication that helps "keep [the virus] from reproducing and causing more liver damage."

The CDC currently says a timely administration of a hepatitis B vaccine is essential to help prevent transmission of the virus from mother to child at birth. While efforts to test for this virus during pregnancy have improved detection, cases can still be missed, or documentation may be inaccurate or incomplete.
