Global production capacity of seasonal and pandemic influenza vaccines in 2023

While influenza vaccine production capacity has been sustained since 2019, significant gaps persist in its distribution, especially in low and lower-middle income countries, and most notably in the African region. This imbalance in production could result in unequal access to vaccines in the event of a pandemic. Strengthening local vaccine manufacturing, promoting seasonal vaccination programmes, and investing in research and development of next-generation influenza vaccines or improved production platforms are essential to improve pandemic preparedness, sustain the influenza vaccine market, and enable more robust local responses.
