Comvax

Generic name: Haemophilus B Conjugate And Hepatitis B Vaccine
Drug class: Vaccine combinations

Usage of Comvax

Haemophilus b conjugate vaccine and hepatitis B vaccine is a combination immunizing agent that is used to prevent infection caused by the Haemophilus influenzae type b (Hib) bacteria and hepatitis B virus. The vaccine works by causing your body to produce its own protection (antibodies) against the disease.

Infections with Haemophilus influenza type b (Hib) bacteria can cause life-threatening illnesses, such as meningitis (a brain disease), epiglottitis (a throat disease that can cause suffocation), pericarditis (a heart disease), pneumonia (a lung disease), and septic arthritis (a bone and joint disease). Hib meningitis may cause death or leave the child with serious and permanent damage, such as mental retardation, deafness, epilepsy, or partial blindness.

HBV infection is a major cause of serious liver diseases, such as hepatitis and cirrhosis, and a type of liver cancer called primary hepatocellular carcinoma.

Pregnant women who have hepatitis B infection or are carriers of hepatitis B virus can give the disease to their babies when they are born. These babies often suffer serious long-term illnesses from the disease.

Immunization against hepatitis B disease is recommended for all newborn babies, infants, and young children.

This vaccine is to be administered only by or under the direct supervision of your doctor.
