Hepatitis B Vaccine
About Hepatitis B Vaccine
Hepatitis B Vaccine belongs to the group of medicines called immunizing agents primarily used to prevent hepatitis B infection. Hepatitis B is a disease that occurs when the hepatitis B virus attacks the liver and causes infection. It can lead to liver cirrhosis (scarring), liver cancer, liver failure, and death.
To build lasting protection, Hepatitis B Vaccine is typically given as a series of injections over several months, and completing all doses is essential. Because it is given as an injection, food intake does not affect how it works. Prioritizing healthy immune support through balanced nutrition and proper rest can help improve your body's response.
Most people experience only mild, temporary side effects after receiving Hepatitis B Vaccine, such as soreness where the shot was given or a low fever. However, you should consult your doctor immediately if you experience signs of a severe allergic reaction, such as swelling of your face, severe dizziness, or breathing difficulties.
Tell your healthcare provider about your medical history, especially if you currently have a high fever, an active severe infection, kidney disease requiring dialysis, or a weakened immune system. Do not receive Hepatitis B Vaccine if you have ever had a life-threatening allergic reaction to yeast, a previous dose of this vaccine, or any of its components.
Let your doctor know if you are taking medications that weaken your immune system, as they can reduce how well the vaccine works. If you are pregnant, breastfeeding, or an older adult, you should discuss your health history with your healthcare provider before scheduling your injection.

Patients Concern
Disease/Condition Glossary
Hepatitis B: It is a severe liver infection caused by the hepatitis B virus (HBV). It is highly contagious (spreads from one person to another) and spreads through intimate contact with the infected person, direct contact with infected blood, through a contaminated needle, using an infected razor/other personal items, or from mother to baby during birth. The virus can live for up to 7 days outside the body. Chronic hepatitis B develops slowly, and the symptoms may not be clear unless complications develop. The symptoms of hepatitis B may appear after three months of exposure to the virus and can last for 2 to 12 weeks. The complications of chronic hepatitis B include liver failure, liver cancer or liver cirrhosis (scarring). Hepatitis B can be prevented by taking the vaccination.
