Vical Receives US Patent For Universal Influenza Vaccine Approach

PBR Staff Writer Published 03 June 2009

To provide protection against circulating seasonal strains and emerging pandemic strains of influenza viruses

Vical has received US Patent No. 7537768, covering the use of influenza virus gene sequences in a universal vaccine that could provide protection against circulating seasonal strains as well as emerging pandemic strains of influenza viruses.

Vical's DNA vaccine technology can induce both antibody and T-cell immune responses against the target portions of the virus, potentially providing a level of protection not available with conventional influenza vaccines.

In addition, a vaccine based on this approach may have the potential to provide protection against future pandemic threats from new strains of influenza viruses.

The follow-on NP and M2 DNA components could be used in a universal influenza vaccine with the potential to protect against a broad range of circulating or emerging influenza strains.
