www.teva-online.org • Page 22 Antigenic and genetic drift of equine influenza virus is monitored by the Expert Surveillance Panel (ESP) which includes experts from the OIE and WHO reference laboratories. 7 Data relating to outbreaks of influenza are reviewed annually and recommendations are made on the need to update vaccines. These recommendations are published in the OIE bulletin (www.oie.int/eng/publcat/ en_bulletins.htm). Since 2010 the Expert Surveillance Panel recommendations are that vaccines for the international market should contain a clade 1 and clade 2 virus of the Florida sublineage. This conclusion was based on the continuing antigenic change and co-circulation of these viruses internationally. It is desirable that all horses, but particularly those that are highly mobile, are vaccinated with vaccines that are most closely aligned to the ESP recommendations. 7 The current OIE recommendations are for a Florida clade 1 virus, such as A/equine/Ohio/03, and for a clade 2 virus, such as A/equine/Richmond/07, to be included in the vaccines. 7 With everything else equal, the vaccine that contains the most recent strains representing those circulating in the field will offer better protection against infection, disease, and viral shedding than a vaccine that contains less closely related strains. 6, 2 References 1.
