Hepatitis B is a viral infection that primarily affects the liver. It is caused by the Hepatitis B virus (HBV) and can lead to both acute and chronic forms of liver disease. The virus is transmitted through contact with the blood or other body fluids of an infected person. Unlike Hepatitis A, which usually resolves on its own, Hepatitis B can become a long-term, chronic infection that can have serious health consequences if left untreated. It is estimated that over 257 million people are living with chronic Hepatitis B worldwide, making it a significant public health issue.
The Hepatitis B virus is primarily transmitted through contact with infected blood or other body fluids. There are several common modes of transmission:
Hepatitis B is often referred to as a “silent infection” because many people infected with the virus do not experience any symptoms. However, when symptoms do occur, they can vary in severity and include:
It is important to note that these symptoms may not appear immediately after infection and can take several weeks or months to manifest. Additionally, some individuals may remain asymptomatic even if they carry the virus, making regular screenings and vaccinations crucial for early detection and prevention.
The Hepatitis B vaccine is a safe and effective way to protect against the hepatitis B virus. It stimulates the body’s immune system to produce antibodies that can fight off the virus if exposed. The vaccine contains a small part of the virus, called the antigen, which triggers an immune response without causing the disease itself. By getting vaccinated, you can reduce your risk of contracting hepatitis B and its potentially devastating consequences.

The recommended schedule for the Hepatitis B vaccine varies depending on the age at which vaccination begins and the specific vaccine used. Here is a general guideline for the vaccine schedule:
The Hepatitis B vaccine is recommended for everyone, regardless of age, as it provides long-term protection against the hepatitis B virus. However, there are certain groups of people who are at a higher risk of hepatitis B infection and should prioritize getting vaccinated. These include:
It is important to discuss your specific risk factors with a healthcare professional to determine if the Hepatitis B vaccine is recommended for you.
