Influenza Studies

The influenza virus is a highly transmissible and rapidly evolving virus that can cause symptoms ranging from mild respiratory distress to severe pneumonia, sometimes leading to death in humans. Researchers are constantly working to develop new vaccines for seasonal and pandemic strains, including a universal influenza vaccine, and improved antiviral therapies.

IITRI is a leading CRO provider of preclinical and biodefense programs to support the development of vaccines and antiviral therapeutics targeting influenza. We additionally offer Biosafety Level 2 and Biosafety Level 3 facilities for studies with high-path inluenza strains, including GLP-compliant studies for IND- or NDA submissions.

Ferret Influenza Model

The ferret animal model is ideal for influenza studies due to the ferret’s natural susceptibility to infection with human influenza A and B viruses, and similar clinical symptoms in response to infection. Ferrets also have similar lung physiology compared to humans, and can transmit human seasonal and pandemic influenza viruses to naïve animals. Ferret animal models are most frequently used for influenza studies at IITRI, although mice, pigs, and non-human primates are also utilized for preliminary studies (mice) or human-like immunogenicity studies (non-human primates). We uniquely offer infection by bioaerosol generation (inhalation) as well as intranasal.
