Influenza Research

Influenza research involves investigating molecular virology, pathogenesis, host immune responses, genomics, and epidemiology regarding influenza. The main goal of research is to develop influenza countermeasures such as vaccines, therapies and diagnostic tools.

The potential H5N1 pandemic has motivated a huge increase in flu research. At least 12 companies and 17 governments are developing pre-pandemic influenza vaccines in 28 different clinical trials that, if successful, could turn a deadly pandemic infection into a nondeadly pandemic infection. A vaccine that could prevent any illness at all from the not-yet-existing pandemic influenza strain will take at least three months from the virus's emergence until full-scale vaccine production could begin; with vaccine production hoped to increase until one billion doses are produced by one year after the virus is first identified.

Improved influenza countermeasures require basic research on how viruses enter cells, replicate, mutate, evolve into new strains and induce an immune response. Solutions to limitations in current vaccine methods are being researched.

The Influenza Genome Sequencing Project is creating a library of influenza sequences that will help us understand what makes one strain more lethal than another, what genetic determinants most affect immunogenicity, and how the virus evolves over time.
