A Map of Influenza Vaccination Campaigns in China

Caption

Research conducted by Fogarty and China CDC scientists identifies three regions for influenza vaccination in China: Annual vaccination campaigns should be initiated in Oct.-Nov. in Northern China (purple) and in February-March in Southern China (green) to accommodate local seasonal influenza activity. In the mid-latitude region around Shanghai (yellow), the optimal timing of vaccination is complicated by semi-annual influenza activity and should be clarified based on further research.
