A sensitiser and booster vaccination of Footvax can be given to all sheep in the flock. The key to effective control is the correct timing of vaccination.
Administered by subcutaneous injection to ewes/lambs in the anterior (front) half of the neck.
When vaccinating, follow the usual guidelines for hygiene and safety. Poor technique can cause pelt damage or site lesions, so take special care to tent the skin and inject between skin and flesh.
Previously unvaccinated flocks - 1st Dose: a sensitising dose, followed at least six weeks later by a booster dose. The booster should be timed to coincide with the lead-up to the period of greatest challenge. This is usually autumn or spring – the bacteria that cause footrot are less active during the coolest months. The booster can be delayed by up to 12 months after the sensitiser dose. This gives you plenty of flexibility when it comes to timing prevention for the greatest danger period. Ewes can’t be vaccinated within four weeks of tupping or lambing.
Subsequent years: a single booster shot to maintain protection. You will get 8-10 weeks protection for fine-wool breeds and up to 14 weeks in English breeds.
Pack size: 250 dose pack.

Important information about Footrot
Footrot is a highly infectious disease causing lameness which is painful, can affect reproductive performance, and reduce wool yield and quantity.
Two bacteria are involved: Fusobacterium necrophorum which first infects the hoof space, typically between the toes, and is then followed by Dichelobacter nodosus which enters deep into the foot leading to under-running of the hoof and a typical smell.
Most commonly seen in warm and wet conditions during Spring and Autumn, the bacteria spreads via infected feet and passes easily within the flock. Ewes in poor body condition due to lameness will usually have fewer, smaller lambs which can directly affect lambing percentage goals.
An ongoing, preventative programme using integrated control methods is the best way of protecting valuable capital stock and farm productivity. It should include some or all of the following elements:
- Regular monitoring of sheep hooves
- Paring and footbathing when necessary
- Separating affected animals
- Culling susceptible animals
- Checking security of boundaries
- Checking bought-in stock and treating if necessary
- A preventative programme of vaccination using Footvax
Vaccination builds immunity against D. nodosus, which is why it can help both prevent footrot and treat it. Early treatment has strong financial and performance benefits for the whole flock. All at-risk sheep, including and especially rams, should be given two doses, six weeks to six months apart, followed by an annual booster. This gives flexibility to fit in with your management.
