The Vaccine-Preventable Diseases and Immunization (VDI) unit supports Member States in advancing comprehensive, resilient and equitable immunization programmes to protect populations across the Western Pacific Region.

This is accomplished by:

• Strengthening immunization systems and programmes to achieve and sustain high coverage, including life-course vaccination
• Supporting the assessment and introduction of new vaccines as they become available
• Preventing and responding to vaccine-preventable disease outbreaks and immunization-related public health emergencies through preparedness and rapid response
• Enhancing surveillance, data systems and intelligence on vaccine-preventable diseases, vaccines and immunization to inform timely and effective action
