Intervacc AB (publ) announces that Strangvac, the company's innovative vaccine against strangles in horses, has been approved by the authorities in Iceland.
Strangles, a potentially lethal infection caused by Streptococcus equi, is the most frequently diagnosed infectious disease of horses worldwide. However, it has not been permitted to import horses into Iceland for over 1000 years and so this country retains the only strangles-free horse population in the world.
Whilst horses within Iceland do not develop strangles, they have no natural immunity and are highly susceptible to this disease should they come into contact with S. equi. This has been a longstanding issue for horses exported from Iceland to other parts of the world.
Strangvac is the only vaccine against strangles that generates a protective immune response, whilst still permitting the diagnosis of horses that have been exposed to, or are infected with, S. equi. This unique feature enables continued disease surveillance to provide evidence in support of Iceland's disease-free status and the protection of exported horses, which is important for Iceland's veterinarians and horse breeders, as well as the new owners!
This approval is particularly noteworthy as the vaccination of horses to protect against infectious diseases is generally prohibited in Iceland, making the decision both unique and highly significant.
"The Icelandic authorities' approval of Strangvac demonstrates their confidence in the utility of this vaccine to safeguard the health of this exceptional breed of horse," says Carl-Johan Dalsgaard, CEO of Intervacc.
Strangvac is now available for veterinary use in Iceland.
