Patent ID: 7914979

Claim:
A method for preserving stability of an enveloped virus, comprising storing the virus in aqueous solution for six months or longer at a temperature from −4° C. to −30° C., wherein the aqueous solution consists essentially of: the enveloped virus at a concentration of from 10 6 PFU/mL to 10 12 PFU/mL; and a non-reducing saccharide, wherein the saccharide is a disaccharide and is present in the solution at a concentration of from 5% (w/v) to 50% (w/v) or a monosaccharide and is present in the solution at a concentration of from 2.5% (w/v) to 25% (w/v); wherein the solution has an osmotic pressure of about 250 mOs or higher; has a pH of from 5 to 10; contains less than 0.1% (w/v) Sodium chloride; and contains substantially no glutamate or phosphate.
