FIELD: veterinary science.
SUBSTANCE: group of inventions can be used for inducing an immune response specific to bovine viral diarrhoea virus type 1b (BVDV-1b) in a mammal. Immunogenic composition contains a modified, live bovine viral diarrhoea virus type 1b (BVDV-1b) and veterinary-acceptable carrier, wherein modified, live BVDV-1b is a TGAC strain of BVDV-1b modified by passaging in tissue culture cells. Group of inventions also relates to use of said composition and method of preventing, treating or relieving one or more symptoms of a disease caused by infection of bovine viral diarrhoea virus, particularly preventing transport fever in an animal.
EFFECT: use of present group of inventions enables to produce a vaccine containing modified live BVDV-1b, which is a TGAC strain of BVDV-1b, modified by passaging in tissue culture cells, which enables to induce immune response.
