Equine Flu Vaccine Adds Protection from Additional Strain

Boehringer Ingelheim Vetmedica Inc., has received approval from the USDA's Animal and Plant Health Inspection Service for a line of equine influenza vaccines trademarked as Calvenza-03. Calvenza-03 EIV (equine influenza virus) and Calvenza-03 EIV/EHV (equine influenza virus/equine herpesvirus) will be the only equine influenza vaccines available that offer direct protection against the newest lineage of equine influenza strains. Calvenza-03 is the only vaccine to include Ohio/2003.

The inclusion of this strain was recommended by the expert surveillance panel on equine influenza vaccines. These equine influenza authorities survey outbreaks of the disease worldwide, track the genetics of the influenza strains involved, and make recommendations concerning the equine influenza strains that should be incorporated in commercial vaccines. They now stress that North American influenza vaccines should include the South Africa 2003 strain, or its equivalent, to maximize potential protection from infection. Calvenza-03 is the only influenza vaccine available in North America to incorporate an influenza A2 strain (Ohio/2003) representative of the genetically distinct South Africa 2003 lineage. Calvenza-03 also includes a relevant Eurasian strain of EIV currently recommended by the expert panel.

With the addition of Ohio/2003, Boehringer Ingelheim Vetmedica, Inc. has improved its Calvenza line of equine influenza vaccines without sacrificing any of its previous protection power. The vaccine protects against a broad range of North American and Eurasian A2 influenza strains by incorporating Ohio/2003, Newmarket/2/93 and Kentucky/2/95, while also protecting against EHV-1 and EHV-4. Plus, Calvenza-03 is the only equine EIV/EHV vaccine that is approved for use in pregnant mares, offers intramuscular and intranasal administration and contains a unique nasal applicator to improve delivery to mucosal surfaces.
