Identification and sizing of the current use cases for seasonal influenza vaccines

The identified use cases of seasonal influenza vaccines can support the optimization of vaccination programmes to increase their public health impact. The use cases identified through this work can help signal to policymakers the most important populations and delivery channels to increase the impact of seasonal influenza vaccination programmes and help estimate programmatic requirements necessary for the supportive policy recommendations. The use cases can also support the design of measures aimed at increasing access in low resource settings and coverage in settings where seasonal vaccines are widely used. The use cases can also help to inform the development, of improved influenza vaccines by highlighting the specific product characteristics relevant to their most impactful uses in different programmatic settings.
