2 ml reconstituted vaccine.

Intranasal and/or intramuscular inoculation. The vaccine must be administered aseptically via the intramuscular route (2 ml) or sprayed into the nostrils (1 ml per nostril during aspiration) with the spray canula supplied in the package.

Shake the vaccine well before use.

Irrespective of the maternal antibodies status a full vaccination course consists of two doses. The first vaccination should be applied intranasally, followed by a second vaccination intramuscularly 3-5 weeks later. Calves should receive their first booster vaccination at the age of 6 months.

Seropositive calves: two intramuscular doses, 3-5 weeks apart.

Seronegative calves: one intramuscular dose.

Pregnant cattle: two intramuscular doses, 3 to 5 weeks apart.

In all cases, vaccination will induce immunity lasting for 6 months. Booster vaccinations are therefore performed every 6 months.

Beef cattle and fattening bulls should be vaccinated preferably just prior to housing (crowding) or when transferred to new groups.

In order to stimulate local immunity in cattle already exposed to IBR or under immediate risk of infection, (including pregnant cattle) it is recommended that the first vaccination is given intranasally. In this case, the second vaccination should be given intramuscularly 3 to 5 weeks later to complete the initial course.

It is recommended that all the cattle in the herd are vaccinated.

Using the sterile diluent provided, reconstitute the freeze-dried product aseptically as follows: transfer approximately one quarter of the solvent into the freeze-dried powder with a sterile syringe; mix thoroughly. Transfer this solution back to the remaining diluent and mix. Following reconstitution the vaccine remains potent for a maximum of 8 hours when the product is withdrawn aseptically and refrigerated.. The needles and syringes used for application of the vaccine must not be sterilised by chemical disinfectants as this may impair the efficacy of the vaccine.
