Non Inferiority Trial of Locally Manufactured 'Hepa-B' Vaccine in Bangladesh.

Summary

Hepatitis B is a common and serious infectious disease of the liver, affecting millions of people throughout the world. Persistent Hepatitis B virus infections may cause development of chronic hepatic insufficiency, cirrhosis and hepatocellular carcinoma. Adding to that, Hepatitis B Virus carriers can transmit the disease for many years. It is transmitted through blood or other body fluids infected with the Hepatitis B virus. It is a major cause of morbidity and mortality in countries like Bangladesh. Immunization with Hepatitis B vaccine has been proved effective to prevent HBV infection. But the vaccines, which are recommended till now, are expensive. Locally manufactured Hepatitis B vaccine will be safe, cost effective and affordable for all. The test vaccine will induce similar seroprotection rates to hepatitis B one month post-vaccination and at 7 months, one month after the third dose of vaccine compared to reference vaccine. This will be done by comparing the percentages of participants with ≥10 mIU/ml anti-HBs by vaccinated with either Hepa B or Engerix B vaccine. The non-inferiority margin will be 10%.
