Patent number: RE37224Abstract: A vaccine for the immunocontraception of mammals is described. The vaccine consists of zona pellucida antigens and an adjuvant encapsulated in a liposome delivery system. The liposome delivery system allows for the slow release of antigen resulting in a prolonged immune response. In particular, after a single injection of the vaccine, levels of anti-zona pellucida antibodies were detected for up to 22 months in seals. Thus, the vaccine according to the present invention is effective after a single dose and is therefore very useful in immunocontraceptive protocols.Type: GrantFiled: July 23, 1998Date of Patent: June 12, 2001Assignee: Dalhousie UniversityInventors: Robert Brown, Michael Mezei, Bill Pohajdak, Warwick Charles Kimmins
