What is Hepatitis B?

The hepatitis B virus is the causative agent of hepatitis B, a serious infection of the liver (HBV). Short-term hepatitis B, sometimes referred to as acute hepatitis B, typically affects individuals for a period of fewer than 6 months. However, the infection may become chronic in certain people, which means that it lasts for more than half a year. If you have chronic hepatitis B, you have an increased chance of getting liver failure, liver cancer, or cirrhosis, which is a disorder that damages the liver permanently. Some of the signs and symptoms of hepatitis B include:

  • Abdominal discomfort.
  • Joint discomfort.
  • A decreased desire to eat.
  • Sickness and throwing up.
  • Weakness as well as exhaustion.
  • Jaundice is the term for a condition when the skin and white of the eyes (sclera) become yellow.

Hepatitis B Vaccine

Second-generation vaccines or subunit vaccines are those that consist of defined protein antigens, such as toxoids or recombinant protein components, developed by genetic engineering.

The hepatitis B vaccine is a second-generation vaccine which is composed of surface antigens of the hepatitis B virus that is obtained from yeast cells using recombinant DNA technology.

A vaccination that may protect against hepatitis B is called the hepatitis B vaccine. It is suggested to administer the first dosage during the first 24 hours after the baby is born and then complete the series dosage as per the guidelines by the medical authority. Additionally, it is suggested that those working in health care be vaccinated. More than 95% of individuals are protected from the disease after receiving regular vaccinations, especially healthy adults.

Final Answer

The hepatitis B vaccine is a second-generation vaccine.
