Hib Vaccines

Hib Vaccines Polysaccharide Vaccine The first Hib vaccine licensed was a pure polysaccharide vaccine, first marketed in the US in 1985 Conjugate Vaccine: The shortcomings of the polysaccharide vaccine led to the production of the Hib polysaccharide-protein conjugate vaccine. Attaching Hib polysaccharide to a protein carrier greatly increased the ability of the immune system of young children to recognize the polysaccharide and develop immunity. Hib conjugate vaccines have been effective against all manifestations of Hib disease, with a clinical efficacy between 95-100%.

Hib Combo Vaccines Multiple combinations of Hib and other vaccines have been licensed in the United States, reducing the number of shots necessary to vaccinate a child. Hib vaccine combined with diphtheria-tetanus-pertussis-polio vaccines and Hepatitis B vaccines are available in the US. The World Health Organization (WHO) has certified several Hib vaccine combinations, including a pentavalent DTP+HBsAg+Hib combos for use in developing countries. Vaccine under development at Bharat Biotech Limited.

Indian Hib Vaccine Manufacturers Serum Institute of India Pentavalent Combo of DTP+HBsAg+Hib Date of WHO prequalification: September 22, 2010.

Sanofi Pasteur (Shantha Biotech) Shan5 – A pentavalent Combo of DTP+HBsAg+Hib Issues with Shan5: Facing Vaccine Quality issues regarding physical appearance reported to WHO by Colombia, Comoros, and Nepal ⇨ No AEFI reported so far ⇨ However, Shan5 likely to be removed from the list of WHO prequalified vaccines if corrective measures are not instituted within 2 months.

Panacea Biotec Easy five - Pentavalent Combo of DTP+HBsAg+Hib Issues with Easyfive: During site audit (27 June-1 July 2011) at Lalru, Panacea failed to meet the quality requirements for WHO prequalification ⇨ As per the recommendations of the ad hoc Committee, Easyfive has be delisted from the WHO prequalified list of vaccines.

Institutional Capacity and Framework Mapping of research capacity and networking. Creation of Bio-repositories. Need to strengthen Public-Private-Partnerships. Need for initiatives for product development for public health emergencies. Vaccine Quality Regulatory System Laboratory testing of vaccine for QC and QA. Fast-track clearance of vaccines needed for emergencies. Clinical trials of vaccines as per GCP. Strengthening and streamlining IPR and Tech Transfer.

Major Recommendations

Vaccine Production and Supply Need for financial sustainability plan (FSP) for immunization. Creation of expanded vaccine fund through innovative financing mechanism. Vaccine Introduction in UIP Indentifying vaccines of local relevance. Setting criteria for selection of vaccines e.g. Grades of Recommendation Assessment, Development and Evaluation (GRADE) System. Role of the National Technical Advisory Group on Immunization (NTAGI) in the decision-making process.

Major Recommendations

Operational Efficiency of UIP Improving vaccine coverage Robust AEFI and VPD Surveillance System Vaccine forecasting, procurement and management Accountability for vaccine wastage Management of the cold-chain Stockpiling vaccines for disasters/outbreaks Management of Human Resources Advocacy and Communication Ethics and Equity – Need for ethical use and equitable access to vaccines Major Recommendations

WHO/TDR Project: Mapping of Products R&D Landscape in Drugs, Diagnostics and Vaccines in India

Brief Outline of the Project

Mapping of the product R&D landscape for infectious diseases of public health importance in India through literature surveys, and internet/database searches.

The Mapping included the following:

Cover R&D activities in the area of drugs, diagnostics and vaccines for infectious tropical diseases. b. Identify gaps and opportunities for product innovation in India. c. Create a database of institutions (public and private) with relevant R&D capacity for discovery and development and manufacturing.

Create a database of available resources including technologies, pathogen strains, screening assays as well as potential regional funding sources that could support such regional efforts.

The link of the database in the form of web portal: http://www.indiandi.org

Mapping Outline Questionnaire Administration to Organizations Associated with R&D / Manufacture of DRUGS, DIAGNOSTICS and VACCINES

PUBLIC SECTOR PRIVATE SECTOR 9 Diseases Targeted as per TDR Mandate: Malaria, TB, HIV-AIDS, Dengue, Filariasis, Leprosy, Leishmaniasis, Helminthiasis, STDs

Diagnostics: Examples of Information Gathered

Genomix Molecular Diagnostics (P) Ltd, Hyderabad, (A.P) is developing and testing POC instrumentation for Lateral Flow and Isothermal PCR (LAMP) assays for Malaria, Dengue, Chikungunya etc.

Also, developing antibody Lateral Flow assays for Taeniasis and cysticercosis in collaboration with Dr. Patricia Wilkins, CDC, USA

PCR (900 gm) Machine Lateral Flow Machine

Example of Malaria Diagnostic Development by National Institute of Malaria Research, Banagalore Product Name Stage of Development Status Future Funding Status Public/Private Funding Comment HRP II/pLDH based rapid diagnostic test for differential diagnosis of malaria. Recombinant antigens have been produced. Native antigen underway. Indigenous production of double window based immuno-chromatographic lateral flow rapid diagnostic tests. RDT Will be produced indigenously. current funding is OK. Needs more freedom in spending the fund

work is funded by DBT under SBIRI programme. M/S Bhat Biotech (I) Pvt. Ltd, Bangalore is the industrial partner . This is a good move by DBT to have Public Private Partnership initiative.

Micro PCR based differential diagnosis of malaria. RT PCR for Plasmodium falciparum and P. vivax has been developed. Indigenous production of chips for micro PCR is underway. Production can be made. Currently this work is being carried out within the available fund. This work is funded by Bigtec Lab Pvt. Ltd., Bangalore This work is partially funded by Bigtec Lab Pvt. Ltd., Bangalore.

Diagnostics: Challenges India is an endemic country for several Infectious diseases. Diagnostics is still unavailable for some of the diseases. Evaluation is a problem. Lack of networking among investigators. Lack of platform technology development, a change visible in recent times. Kits and chips also were not in sight earlier, which are coming up now. Insufficient Industry-Academia partnership. Hurdles in IP procedure.

Diagnostics: Gaps and Roadblocks As identified from the inputs collected from the Principal Investigators: Finance. Infrastructure. Reagents. More basic research for neglected tropical diseases. Inability to differentiate between active and latent disease or active disease vs. contacts. Not enough clinical samples. Lack of containment facilities. Lack of human resources. Quality assurance. Limited option for test validation. Inaccessibility to good quality validated panels of sera. Imported kits, chips, reagents make diagnostics costly.

MAPPING OF DRUGS

Drugs: Gaps and Roadblocks Gaps and roadblocks, as perceived by respondents from Academia :

Lack of manpower. Lack of funding. Lack of infrastructure. Neglect of some diseases over others.

Vaccine Manufacturing in India Vaccine manufacturers from India started the journey by manufacturing EPI vaccine, a niche created by exit of few multinationals from the area. But they have gone a long way after that …

WHO prequalification regulations getting more stringent. Older public sector units have been converted to testing centers. New manufacturers have entered the scene.

Few have done very well .

An Example: Serum Institute of India Limited, Pune New Products Aerosol measles vaccine In phase III clinical trials Acellular Pertussis vaccine Ready for preclinical studies Rotavirus vaccine Ready for preclinical studies Pandemic influenza vaccine In development

New Concepts Liposomal vaccines For simplifying the vaccine delivery

Liposomal anticancer products

Conjugated therapeutic proteins To increase the half life of the products

Meningitis Vaccine Project Created in 2001 as a partnership between WHO and PATH Affordable price through innovative international partnerships PROJECT STATUS Phase I clinical trials completed

Phase II clinical trials completed: Vaccine is highly immunogenic

Phase III clinical trials started in Mali, Senegal and India in 1Q 2010

Applied for WHO prequalification
