The present invention relates, in general, to attenuated equine influenza viruses having an impaired ability to antagonize the cellular interferon (IFN) response, and the use of such attenuated viruses in vaccine and pharmaceutical formulations. In particular, the invention relates to attenuated equine influenza viruses having modifications to an equine NS1 gene that diminish or eliminate the ability of the NS1 gene product to antagonize the cellular IFN response. These viruses replicate in vivo, but demonstrate decreased replication, virulence and increased attenuation, and therefore are well suited for use in live virus vaccines, and pharmaceutical formulations.

The invention is for a DNA vaccine expressing the hemagglutinin (HA1) gene of equine-2 influenza virus. By engineering a stop codon within HA1, expression of HA1 is ensured. By encapsulation of the DNA vaccine in liposome and by intranasal inoculation, it is sufficient to elicit protective immunity at a significantly lower dosage compared to a DNA vaccine expressing the full length HA gene. Lower dosage reduces the risk of induction of anti-DNA antibodies. Intranasal inoculation directly to the respiratory epithelial cells reduces the risk of DNA integration. The inventive vaccine is advantageous over current inactivated or live attenuated vaccines, as updating of the vaccine requires only the replacement of the encoding sequence with the new virus.
