How Effective is the Vaccine in Preventing Liver Damage?
The hepatitis B vaccine is over 90% effective in preventing HBV infection and its associated liver damage. Vaccinated individuals are protected against acute hepatitis B and the chronic complications that arise from persistent infection. Histologically, vaccinated individuals are less likely to show signs of chronic liver disease such as inflammation, necrosis, or fibrosis that are typical in unvaccinated, infected individuals.
