As the most common liver disease in the world, Hepatitis B is a life-threatening liver infection caused by the hepatitis B virus, or HBV. It can cause chronic infection and put people at a high risk of death from cirrhosis (scarring of the liver) and liver cancer. In 2015, 257 million people were living with a chronic form of hepatitis B, and almost 900,000 people died from it. In this video, you’ll learn a bit about the background of hepatitis B, its symptoms, transmission, molecular mechanism, prevention, and treatment!

Hepatitis B has a vaccine administered over a six month period in around three doses. It is often advised to have blood drawn after the last dose to assure that your blood contains the correct antibodies and that you are protected. Even if you get the vaccine, always take care when handling body fluid and use personal protective equipment. The vaccine must be administered to all employees who fit into a type A role, who will or may come into contact with blood and body fluid by job description, which for some work places only has to occur after the first exposure incident.

Hepatitis, basically the viral Hepatitis. It is 5 types, A,B,C,D,& E. Hepatitis B has got a vaccine. All the child after both has to be vaccinated and all adults who have not been vaccinated they should be tested and if they are negative they should get vaccinated. Usually vaccine is given in 3 doses, especially the Hepatitis B vaccine. That is Zero, dose is Day 1, then one month later 1, and 3rd dose, 6 months later. This is the Hepatitis B vaccination schedule. Once in 5 years there is a Hepatitis B vaccination booster dose. Nowadays we don’t use it in general public but in high risk patient is basically those patients who have Hepatitis B patients in their family, nurses, doctors, we take booster doses every 5 years and there is a vaccine for Hepatitis A also and it is given intramuscularly, usually 1 dose and then that gives considerable amount of immunity for those patients, whereas Hepatitis C and Hepatitis E, they don’t have a vaccine.
