Fendrix vaccine for Hepatitis B

Benefits of Fendrix vaccine are mainly to protect against hepatitis B.

It is used in patients with Hepatitis B disease:

  • patients undergoing hemodialysis – where the dialysis machine removes slag products from the blood
  • patients who will undergo hemodialysis in the future.

Fendrix is ​​used in adults and adolescents 15 years of age and older.

What is hepatitis B?

Hepatitis B is caused by a virus that causes liver swelling.

  • It is possible that signs do not appear until 6 weeks to 6 months after infection.
  • The main signs of illness include mild flu symptoms such as headache or fever, feeling tired, dark urine, pale stools, yellowish skin, or whites of the eyes (jaundice). These or other signs may mean that the person may need hospitalization. Most people recover completely from the disease.
  • Some people with hepatitis B do not look sick or do not feel sick – they have no signs of illness.
  • The virus is found in body fluids such as the vagina, blood, seme,n, or saliva (saliva).

Carriers of hepatitis B

  • The hepatitis B virus stays in the body throughout the life of some people.
  • This means that they can still infect other people and are called virus carriers.
  • Carriers of the virus are at risk for serious liver problems, such as cirrhosis or liver cancer.

How Fendrix vaccine works

  • Fendrix helps your body make its own protection against viruses ( antibodies ). These antibodies will protect you against the disease.
  • Fendrix contains two substances called MPL (a non-toxic purified fat derivative from bacteria) and aluminum phosphate. These make the vaccine work faster, better,r and have a longer effect.
  • As with all vaccines, treatment with Fendrix may not fully protect all vaccinated individuals.
  • Fendrix may not protect you from getting sick if you have already had the hepatitis B virus.
  • Fendrix can only protect you against infection by the hepatitis B virus. It can not protect you against other infections that can affect the liver, even if these infections have similar signs to those caused by the hepatitis B virus.
