Seasonal Influenza

Annual influenza epidemics cause significant levels of illness and death each year. Visit this section to learn more about the disease.

Avian Influenza

Low pathogenic influenza has occurred for centuries in a range of birds. However, since 1997 highly pathogenic H5N1 avian influenza has spread to many countries around the world.

Pandemic Influenza

Global influenza pandemics occur periodically causing widespread sickness, death and disruption. The largest pandemic of the last century occurred in 1918-19, killing 40-50 million people.

Influenza Vaccines

Vaccines are used in many countries to control seasonal influenza. Their production is complex and time constrained to allow the inclusion of strains based on the latest surveillance data.

Influenza Vaccine R&D

Manufacturers have introduced a number of new influenza vaccines recently, and continue to progress R&D in the field.
 

Avian & Pandemic Vaccine Trials

IFPMA members conduct significant research into vaccines designed to address pandemic influenza. This section provides updates on the progress of clinical testing with these vaccines.
