World Health Organization (WHO) WHO is a specialised agency of the UN serving as the directing and coordinating authority for international health matters and public health on behalf of its 194 Member States.Principle objective - the attainment by all people of the highest possible level of health.WHO is responsible for providing leadership on global health matters, shaping the health research agenda, setting norms and standards , articulating evidence-based policy options, providing technical support to countries and monitoring and assessing health trends. Setting norms and standards and promoting their implementation is one of WHO core functions .

WHO Biological Standardization WHO has played a key role for over 60 years in establishing the WHO Biological Reference Materials necessary to standardize biological materials as well as developing WHO guidelines and recommendations to assure the quality, safety, and efficacy of biological products. These norms and standards, based on scientific consensus achieved through international consultations, assist WHO Member States in ensuring the quality and safety of biological medicines and related in vitro biological diagnostic tests worldwide. The Organization accomplishes this biological standardization work through its biological programme co ordinated by a Secretariat at WHO HQ; the WHO Expert Committee on Biological Standardization (ECBS) selected from an Expert Advisory Panel on Biological Standardization ; and WHO Collaborating Centres for Biological Standardization.

Implementation of standards - tools Implementation workshops: Lectures on selected topicsCase studiesWork in groups of 6-8 participants where regulators and manufacturers discuss application of guiding principles to specific examples Facilitators help clarifying the points needed for discussion and each group comes up with a conclusion and key arguments that support their opinion In some cases, there is no consensus but options for proceeding further Good learning opportunity but limited to certain number of workshop participants ( eg . 30-40 participants) Publications – meeting reports, case studies from implementation workshops Special issue in Biologicals – Vaccine Stability and Similar Biotherapeutic Products E-learning tools, Webinars

Implementation of standards – 2013-2016 General TopicsStability Evaluation of Vaccines – 2013Evaluation of Cell Substrates - 2013 Vaccine Lot Release - 2015 Post approval changes of vaccines - 2015 Specific issues related to Vaccines or Biotherapeutic Products Selected vaccines with complex issues such as: Evaluation of combined vaccines based on DTP – Indonesia, May, 2014 Typhoid conjugate vaccine – China, November, 2014 Malaria vaccine – South Africa, November, 2014 HPV - 2016 Evaluation of Biotherapeutic Products - 2014 Evaluation of SBP - 2014

Implementation of standards – case studies Implementation workshops provide: Good learning opportunity for participantsAmong all materials, case studies were recognized as preferred format for illustrating application of WHO guiding principles Publications: Meeting report from implementation workshop on evaluation of combined vaccines based on DTP – available at http://www.who.int/biologicals/areas/vaccines/combined_vaccines/en / Case studies from implementation workshops on cell substrates – as an example Adventitious agents in viral vaccines: Lessons learnt from 4 case studies ( Biologicals 42 (2014) 223-236) E-learning tools – to be developed for BTP, SBP, vaccine stability, cell substrates, vaccine lot release in 2015-2016; other topics to be considered

Collaborating Centers Recent designations:NIFDC – Jan 2013PEI – Aug 2013Recent re-designations:NIBSC – July 2013 NIID – Aug 2014 TGA – Aug 2014 Current status: 8 CCs for standardization and evaluation of vaccines Additional expertise and broader experience available in CCs which has increased capacity for responding to expectations of the users of standards Concept of global CC with technical support to various regional and inter-country networks of regulators Information on WHO web site for biologicals – revision of the page for CCs to provide regular update on the activities of CCs

WHO Network of Collaborating Centers 1st meeting held in April 2012 – meeting report published in Biologicals 40 (2012), 499-5062 nd meeting of the CC network on vaccine standardization, March 2014 at PEI, Langen, Germany: m ain issues discussed: 1) current ToR of individual CCs, 2) criteria for success of the CC network, 3) key areas where the network should focus its efforts and 4) priorities for coming yearsgood opportunity for CCs to understand current approach and needs of one global and several regional regulatory networks that WHO supports agreed that the CC network should focus on standards, both written and measurement, as well as their practical application to support WHO initiative in promoting science based regulation of vaccines worldwideall CCs confirmed commitment to help WHO to improve efficiency in responding to the needs of its member states. In particular, development of new vaccines was recognized as an area where the CC network can provide more valuable support than the individual CCs.Consensus reached that the CC network will focus on the following:Improve approaches to support implementation of WHO standards into regulatory practiceImprove the efficiency of the global standards setting process, andIdentify gaps in WHO standards and set regulatory science agenda to address gaps
