What is a Hepatitis B Vaccine 

The Hepatitis B vaccine is a vaccine that helps protect against infection with the Hepatitis B virus.

Hepatitis B is a viral infection that primarily affects the liver. Hepatitis B can cause both acute and chronic liver disease and may lead to serious complications such as cirrhosis, liver cancer, and liver failure.

The vaccine works by stimulating the body's immune system to produce antibodies against the Hepatitis B virus. These antibodies provide protection and greatly reduce the chances of the virus from causing infection if a person is exposed to HBV in the future.

Who should take the Hepatitis B Vaccine

We recommend infants and children to get the Hepatitis B vaccine. Certain groups are at higher risk of exposure to the virus and are especially encouraged to get vaccinated, including:

  • Travelers to countries with a high incidence of Hepatitis B
  • Sexual partner or family member of Hepatitis B virus infected individuals
  • People with certain medical conditions, such as heart disease, diabetes, and lung disease
  • Health care workers

For patients, we recommend checking an anti HbS level (blood test) before and 3 months after the course of vaccination. This is usually paired with a HBsAg level. This is to ensure that you have the appropriate amount of circulating antibodies to protect you against Hepatitis B.
