Reconstitute each 5 dose vial with 10 ml sterile diluent. Immediately give 2 ml reconstituted vaccine intramuscularly.
As far as possible take reasonable aseptic precautions in reconstituting and withdrawing vaccine. Reconstituted vaccine should be used immediately. Do not use chemically sterilised syringes or needles, as these will affect the effectiveness of the vaccine.
Vaccination programme
Animals older than 4 months of age
Give 2 doses three to four weeks apart.
Animals from 7 days to 4 months of age
Give 2 doses with a 3 to 4 week interval, with a third dose at 4 months of age. The third dose is required due to the possible interference from high titres of maternally derived antibodies during the first few months of life. An interval of at least 14 days should be observed between the second and third injection.
Ideally animals should be vaccinated during the autumn or at housing prior to the period of greatest risk. Maximum protection occurs when the whole herd is vaccinated.
