AN AQUEOUS COMPOSITION COMPRISING A BIOLOGICAL ANTIGEN AND AN ACRYLIC ACID POLYMER

摘要

The present invention is directed to an aqueous composition comprising an electrolyte to contain a biological antigen and an acrylic acid polymer and to provide an osmolar concentration higher than the osmolarity of a 0.9% (w / v) aqueous sodium chloride solution. The present invention also relates to a pharmaceutical composition for use in a one shot vaccine against porcine syringovirus 2 (PCV2) and optionally Mycoplasma hyphneumonia, and a pharmaceutical composition comprising a To acrylic acid polymers for use in aqueous compositions to reduce heat generation.
