Hysolv says the vaccine, which was developed by IDT Biologika, has been used successfully in Germany, where 1.7 million doses have been prescribed. The company says field trials have shown that vaccination not only protected against clinical signs of influenza but also resulted in improvements in reproduction and piglet performance.
Two 1 ml doses of the inactivated vaccine can be injected intramuscularly three weeks apart to pigs from 56 days old, providing immunisation to the majority of animals within seven days.
Hysolv director, Geoff Hooper said: "Swine flu can be devastating to a herd and this vaccine will broaden protection, particularly when used with our existing vaccine Respiporc FLU3, which we are strongly advising."
Respiporc FLU3 protects against three other strains of swine flu (H1N1, H1N2 and H3N2). Hysolv says that when used together, the two vaccines protect pigs against the most relevant strains in the British Isles.
Geoff added: "There have been several flu pandemics throughout the years – the latest in 2009. It is not possible to predict the emergence of a pandemic strain accurately but this vaccine combined with Respiporc FLU3 will greatly decrease the chance of pigs becoming infected."
