The vaccine against avian influenza of the H9N2 subtype is inactivated and emulsified. The vaccine is made from the extraembryonic fluid of chicken embryos infected with the H9N2 strain of avian influenza virus, inactivated with formaldehyde, with the addition of the oil adjuvant ISA70, manufactured by SEPPIC, in a ratio of 30:70. In appearance, the vaccine is an emulsion from white to white-pink in color. When storing the vaccine, it is allowed to precipitate a dense white fraction with an emulsion clearing in the upper part of the vial, without separating the aqueous phase. The uniformity of the emulsion is restored by careful shaking. The vaccine is packaged in 10 cm3 (20 doses for chickens, 40 doses for chickens), 20 cm3 (40 doses for chickens, 80 doses for chickens), 100 cm3 (200 doses for chickens, 400 doses for chickens), 500 cm3 (1000 doses for chickens, 2000 doses for chickens) glass and/or polymer vials of appropriate capacity, hermetically sealed with rubber stoppers reinforced with aluminum caps. Storage for 18 months from the date of manufacture, subject to temperature conditions, freezing is not allowed.
