Prequalification progress - Vaccines Dr David Wood, Coordinator, Quality Safety and Standards (QSS), Department of Immunization, Vaccines and Biologicals (IVB)
Outline • Review of progress • Current and future synergies
Vaccines prequalified by WHO: Status 2010 (assured quality) 15 industrialized country mfrs 7 emerging economy country mfrs 24 manufacturers 36 Sites 106 pre-qualified vaccines used in 124 countries 64% total population
100 meetings in 2009 with manufacturers and other stakeholders 31 new vaccine tests available through WHO contracted labs
Revision of vaccines PQ procedure • The vaccines prequalification procedure (WHO/IVB/05.19) was last revised in 2005 • WHO plans to update the vaccines prequalification procedure in 2010 to take into account technical, communication and policy revisions • The revision process is described in a concept paper available to meeting participants
Prequalification of immunization related equipment – the Performance, Quality & Safety (PQS) scheme A defined scope - 3 functions • Identify requirements & develop and maintain performance specifications and verification protocols. • Pre-qualify products and accredit test laboratories • Monitor products post-market & Prospect innovations A structured organization • Secretariat hosted at WHO • Inter-agencies and intersectoral Steering Committee • Ad hoc working groups according to categories • Involvement of experts from: industry, laboratories, standard bodies, institutions, freelance experts. A PQS Web based database At its final phase of development
Performance, Quality & Safety Online published documentation • Published SOPs for all functions • Guidelines for manufacturers (published 6) • Performance specifications & Verification protocols for all product sub-categories • Information sheets on laboratories • Product information sheets for all prequalified products • Soon online catalogue • Online search • Downloadable • Printing option
Increase the number of products by category to ensure fair competition Institute a functional user-feedback system Build up on existing active partnerships Develop a tool to assist NRAs in strengthening their role of overseeing the equipment for immunization. Establish a reality check hub for needs assessments and field test of newly developed/introduced devices and equipment. Performance, Quality & Safety The way forward …. Financing of the project Annual cost: US$ 500.000 Cost recovery US$ 150.000 Gap US$ 350.000
Partners (UNICEF, GAVI, BMGF, PATH, manufacturers) More and faster prequalification of vaccines Synergies with/between countries (1) 100% of vaccines used in national immunization programmes are of assured quality by 2013 (SO11 MTSP indicator) • Countries • crisis management for vaccine safety events
Synergies with/between countries (2) Functionality of NRA's in key developing countries that supply affordable priority vaccinesis sustained and increased • Observed audits • Regulatory Mentoring to Strengthen Capacity – Health Canada/CDSCO India case study • Networking – Developing Country Vaccine Regulator's Network - Developing Country Vaccine Manufacturer's Network

Synergies between PQ programmes • Joint audits of NRA's (2009) - Egypt: review and strengthening of components of the regulatory system -Bangladesh: Joint review of Medicines and Vaccines - Led to joint development plan for support to core activities • Common functions of NRA's (examples) -Marketing authorisation and licensing - Oversight of clinical trials • Internal Working Group - Comparison between the WHO PQ procedures
Vaccine prequalification resource gaps • Relative modest budget (capped at 19.3 million$) given scope of work to service all WHO Member States • Funding gap from 2010 onwards (due to sun-setting of some existing grants, plus high dependency on 1 major donor) • Flexible funds are being lost -disproportionately affects core activities, eg normative work • Ways forward: (a) increase awareness of need for flexible funding of critical core functions (b) business plan to be developed
