Bovilis® BTV8

Intervet has developed an inactivated vaccine for the aid in the prevention of BTV 8 infection. It contains an inactivated virus strain isolated from one of the outbreaks that took place in Europe in 2006, alongside a dual adjuvant system that ensures the delivery of both a cell-mediated and a humoral response.

Independent challenge studies have shown that the vaccine can prevent viraemia in sheep following a single dose. Studies in cattle have shown that vaccination can reduce the level and the duration of the viraemia following a vaccination course comprising two doses given three weeks apart.

Vaccination schedule
