1 World Health Organization Western Pacific Regional Office Expanded Programme on Immunization WHO Region for Western Pacific 10 th Annual Measles Initiative Meeting Update on Measles Elimination in the Western Pacific Region Washington, DC September 13, 2011 Dr David H. Sniadack, Medical Officer, EPI

2 World Health Organization Western Pacific Regional Office Expanded Programme on Immunization Urged member states –to commit human and financial resources –to develop and implement work plans –to regularly report surveillance data to WPRO –to establish independent national verification process following the establishment of standardized regional verification mechanisms by WPRO –to accelerate control of rubella and the prevention of congenital rubella syndrome Requested the RD –to establish regional verification mechanism –to strengthen technical cooperation with Member States to achieve regional immunization goals –to seek additional resources to achieve regional goals utilizing frequent ICC meetings and other mechanisms –to report progress periodically to the Regional committee Regional Committee Resolution, 2010 WPR/RC61.R7 Reaffirmed the 2012 measles elimination goal! Accelerate rubella control and CRS prevention!
