Vaccines and methods of inoculation for conferring immunity to Cryptococcus infection are disclosed. Strains of Cryptococcus fungi, including Cryptococcus neoformans and Cryptococcus gattii, can be administered to a human or animal subject via inhalation. Cryptococcus fungi that can be used to confer immunity can comprise one or more mutations in genes that contribute to chitosan production, such as genes encoding a chitin deacetylase (cda), a chitin synthase (chs) and / or a regulator of chitin synthase (csr). Inhalation administration of heat-killed Cryptococcus harboring deletions in cda1, cda2 and cda3 genes can confer immunity. In a murine model system, inhalation administration of Cryptococcus neoformans harboring deletions in cda1, cda2 and cda3 genes conferred immunity against subsequent exposure to wild type Cryptococcus neoformans in 100% of test animals. Inhalation administration of heat-killed Cryptococcus grown under conditions leading to reduced chitosan production can also confer immunity.

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.
