19. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Priority Activities of Measles Elimination Western Pacific Region, 2011-2012 Closing immunity gaps, focusing on priority countries Conducting quality SIAs, incorporating MR when feasible ⁻2011: CAM (Feb-Mar, MV, ? Oct), PHL (Apr, MR), LAO (Nov, MR) ⁻2012: PNG and several Pacific island countries Improving routine MCV1 and MCV2 coverage –Introduction of MCV2 (CAM > 80% since 2008) –Exploring practical approaches to identifying under-served population groups/communities and improving their access to immunization services ⁻Link to needed solution to address quality gaps in previous SIAs (vaccination of children 5-14 years old in CAM) Identify and implement appropriate approach to and strategies for immunizing adults –Key constraints: funding, vaccine production capacity (MV or MR) Epidemiologic analysis of adult measles cases in Beijing, China in collaboration with US CDC and WHO

20. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Continue to improve surveillance, maintain accredited lab network, and provide more support to priority counties Regional Level –Publish Measles and Rubella Bulletin monthly (planned in April 2011) –Frequent data analysis of countries –Update/revise field measles guidelines, incorporating rubella –Accreditation of all RRLs and NMLs in 2011 Country level –Capacity building at country level: surveillance workshops CAM, LAO, PNG, VTN –Country visits, followed by extensive follow-up actions Priority Activities of Measles Elimination Western Pacific Region, 2011-2012

21. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Initiate preparation for verification of measles elimination Establish regional verification committee for measles elimination Develop guidelines on verification of measles elimination for the region Organize 1 st regional verification commission meeting (September 2011) Assist countries in initiating preparation upon country requests Priority Activities of Measles Elimination Western Pacific Region, 2011-2012

22. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Encourage introduction of RCV in Member States –With > 80% MCV coverage: CAM (GAVI support), VTN –With a need for frequent SIAs: LAO, PNG, SOL, VAN Establish CRS sentinel surveillance (CHN, VTN) Studies on disease burden of CRS (LAO, PHL, VTN) Priority Activities of accelerating Rubella Control & CRS Prevention, Western Pacific Region, 2011-2012

34. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Challenges of Measles Elimination Western Pacific Region High measles incidence in several countries Evolving epidemiology –Shifting to infants and adults –Increased risk of measles transmission in densely populated urban areas Importation and exportation –Importation: to Australia and New Zealand from several countries and Regions –Exportation: from Philippines to Australia, Canada, Japan, New Zealand and U.S.

35. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Difficulty in ‘eliminating’ immunity gaps –Inadequate monitoring to identify low coverage areas/ populations –Inadequate systems and/or resources to increase responsiveness to under-served populations –Identifying and addressing quality gaps in previous SIAs – Identifying and implementing appropriate strategies to address measles in infants and adults Challenges of Measles Elimination - Immunity Gaps

36. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Challenges of Measles Elimination - Surveillance Low sensitivity of surveillance at sub-national levels Difficulty in timely obtaining accurate epidemiologic data –Delayed and incomplete case investigation data –Discrepancies between lab reports and national reports Large proportion of clinically confirmed cases in some countries Inadequate attention to collecting specimens for virus detection

37. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Challenges of Measles Elimination Funding gaps: Increasing needs and decreasing resources/sources Competing priorities and stretched HRs High level and broad political commitment –Interest and confidence in measles elimination

38. World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Reasons for Missed Opportunities to Rubella Control Lack of evidence –Although rubella case are identified in greater numbers, CRS is under-reported and under-recognized in most developing countries in the region, resulting in less priority Lack of motivation –Perception that control of rubella and prevention of CRS is an additional task: health officials are not motivated especially under pressure of eliminating measles by 2012
