Orange County Influenza (Flu) Vaccination Details

Influenza - Flu

Influenza is a viral disease that causes upper respiratory infection, fever, cough, and nasal discharge. There are multiple strains of influenza viruses, just as there are multiple strains of flu viruses in humans. Almost all influenza vaccinations have multiple strains of flu virus in each dose.

The frequency of vaccinations for influenza is influenced by exposure. At one extreme, you have an older adult horse that is never exposed to other horses. Such a horse may only require vaccination annually. If that same horse is boarded at a large stable, then vaccination every six months would be wise. In contrast, a horse that is competing or is being exposed to a large number of other horses on a regular basis should be vaccinated every three—four months.
