A global review of seasonal influenza vaccine introduction: analysis of the WHO/UNICEF Joint Reporting Form.
Background: Influenza is a highly contagious disease that affects the upper and lower respiratory tract caused by several subtypes of influenza viruses. While vaccination remains the mainstay strategy to protect populations against influenza, there is a global shortage and inequitable access to influenza vaccines. Although influenza vaccine production capacity increased from 500 million doses in 2006 to 1.5 billion doses in 2013, little is known about the global distribution of these vaccines albeit its introduction. ⋯ Among countries (n = 117) that had introduced the vaccine, children (56%), older adults (87%), and risk groups (99%) were prioritized and given the vaccines. Conclusions: Introduction of influenza vaccine in the African and Southeast Asian regions remains suboptimal. This critically underscores the need for financing mechanisms and having countries in the regions that are lagging behind to prioritize seasonal influenza vaccine.
