ABOUT THE PROJECT
a new initiative of
In association with Dept. of Health, Govt. of Tripura
- The Discovery of Hepatitis B:
In 1980-81, Maurice Hilleman first discovered the plasma derived vaccine and was approved by FDA for human use in 1981. It was not very successful in the market place, because clinicians knew that it was a product from human blood source. Hilleman’s collaborators succeeded in 1986 in making the antigen in yeast. This vaccine is recombinant DNA vaccine. This is the vaccine still in use today. In 1991 Hepatitis B became part of the recommended immunization schedule in the United States and many other countries of the world.
- Hepatitis B Transmission:
- Hep B virus leading to Chronic Liver Disease:
If infection occurs during birth, 95% of the new born gets chronic liver disease, but 30% younger children can clear the virus and 95% of adults can do so.
It means mother to child transmission is the most dangerous, from transmissibility and disease Chronicity point of view.
Historical approach to Hepatitis B Vaccination:
- 1965: Hepatitis B virus discovered.
- 1982: Hepatitis B vaccine first became available.
- 1984: Taiwan launched first universal vaccination against Hepatitis-B.
- 1992: WHA resolution 45.17 called for member states, "…to integrate cost-effective new vaccines, such as Hep B, into national immunization programs in countries where it is feasible…"
- 1992: WHO recommended that all countries integrate hepatitis B (Hep B) vaccine into national immunization programs by 1997.
- 1998: WHO Conference Regarding Disease Elimination and Eradication as Public Health Strategies concludes hepatitis B ”a primary candidate for elimination or eradication”
- 2005: WPR sets goal of reducing chronic HBV infection rates to less than 2% among 5-year-old children by 2012.
- 2007: Over 88% of member states (171 out of 193) have introduced Hep B at birth vaccination in expanded program of immunization.
- 2007: Hep B-birth dose global coverage 27%, and Hep B3 coverage 65%.
- 2008: SAGE strongly recommends "all regions and associated countries develop goals for hepatitis B control appropriate to their epidemiologic situations". (1)
- 2010: World Health Organization declared “28th July” as World Hepatitis Day.
- Scientific Basis of Hepatitis B Vaccination at birth:
The birth dose of hepatitis B vaccine is recommended by the National Health and Medical Research Council, USA and almost all scientific bodies. Serologic surveys provide evidence that the incidence and prevalence are dramatically reduced in populations that have universal vaccination of infants. Several studies have shown that in the first decade of life, acute infections are uncommon, and chronic infections are rare in populations in which infants are vaccinated. The risk of chronic infection is highest in the young: 90% for infants, 70% for children and 5% for adults.
30% of hepatitis B infections are not associated with a known or disclosed high risk activity
30% of hepatitis B infections are not associated with a known or disclosed high risk activity
Hepatitis B vaccine works better in infants compared to older children and adults
Some mothers miss being tested for hepatitis B in pregnancy
Sometimes the mothers blood test results are missing, inaccurate or recorded wrongly
Mothers at high risk for getting hepatitis B disease may miss having their second hepatitis B test which should be done close to labor (hepatitis B can take 1-9 months to show up in a blood test from the day of infection)
The birth dose of hepatitis B vaccine is also recommended because: It reduces the risk of babies getting hepatitis B disease from a household member who is a hepatitis B carrier (this is not always known) "At risk" babies may otherwise miss out on having the vaccine. It provides protection from hepatitis B disease for babies who may be late with their first dose of immunization.
- Scenario in India:
The report shows that at birth infant Hepatitis B vaccination could be the best way to reduce the burden of disease. However, even after 20 years of adoption of at birth vaccination policy by many countries of the world, India could not take the initiative. Our country is the rarest example which has got “No policy for Hepatitis B vaccination”, though India is in intermediate zone of disease prevalence and need to be reduced.
- Scenario in China & Taiwan:
On the contrary China, having the largest population of world introduced “At Birth vaccination” as early as 1990. In that year itself they have achieved 73.29% success rate. From 1999 they have started having >99% at birth vaccination and in 2009 they got 99.98% success. It shows a good Governmental policy can make the vaccination program most successful and ultimately can reduce the disease burden. Taiwan started at birth vaccination as early as 1984 & could reduce Hepatitis B infection from > 20 % to <2 % by 2000 AD. They have reduced the Liver Cancer drastically.
- In Tripura:
Tripura is a small state of India & cannot have separate policy for Hepatitis B prevention. Further 31% of State’s population is from aborigine group, in whom disease prevalence is more than 8%. Most of the people are living in deep interior place, which has further reduced the accessibility. (2)
- At Birth Vaccination:
New Project of Hepatitis Foundation of Tripura “At Birth Hepatitis B Vaccination”- “- is going to be a historical initiative, after the success of Hepatitis B Eradication Program.
All infant born in hospital should be given at discharge vaccination.
All infant born at home should also be brought under the coverage of the program (up to 14 days).
- Methodology:
Selection of Centers: All the Health Institutes of Tripura wherever Institutional delivery is taking place will be included in this project in a sequential manner.
Infrastructure:
A. MCH centers of all Health Institutes.
B. Branches of Hepatitis Foundation of Tripura.Logistics:
Vaccine, Syringe, Register and Card etc will be supplied by HFT to the respective Health Institutes.
At Birth Hepatitis B Vaccination schedule:
At birth Hepatitis B Vaccination is given following the same schedule as in adult i.e. 0-1-6 month. The first dose will be given before discharge from the hospital and second dose will be given after one month and third dose is given after six month.
- Financial Involvement:
1. First dose of Hepatitis B vaccine for child born in hospital will be given free of cost. This will involve an expenditure of Rs. 8 lac every year.
2. The second and third dose of vaccine (at 1 month & 6 month) will be given in Hepatitis Clinics of respective Hospital against a subsidized price of Rs. 20/-(Twenty) only per dose.
Awareness Generation & Help by BRISTOL MYERS SQUIBB FOUNDATION:
Hepatitis Foundation of Tripura will take all steps for awareness generation among all care providers & pregnant mother .International philanthropic organization BMSF promised to extend help for Awareness Generation but not for vaccination.
- Role of Govt. Of Tripura Govt of Tripura has issued necessary order & requested all Health Care Providers to participate in the program actively.
- Finally:
Hepatitis Foundation of Tripura has got wonderful infrastructure and dedicated volunteers throughout the state. The State Government of Tripura with all constrain is extending enormous institutional support to the foundation. At birth vaccination program will be an innovative initiative. This will definitely reduce the prevalence of Hepatitis B in Tripura. This will be a path breaking event in India. This will also increase the Institutional Delivery.
After the success of Hepatitis B Eradication Program we are confident that we will succeed in our future program of At Birth Vaccination. We need help and support of all concerned.
