An oral vaccine against parasitic protozoa, such as coccidia, comprises live encysted protozoa embedded in a firm gel matrix from which the protozoa are released following ingestion by a host. The gel matrix helps to maintain the essential viability of the protozoa without seriously hindering the natural mechanism by which they infect their host. Preferably the gel matrix is based on alginate. Alginate beadlets containing viable sporulated coccidia oocysts, for administration to poultry, are a preferred feature.
A composition useful in oral immunisation of animals such as poultry comprises dry free-flowing particles each consisting of a solid beadlet of lipid-continuous emulsion containing from about 25% to about 50% by weight water in a lipid, such as hardened palm kernel oil, having a slip point in the range 35 to 45°C, each beadlet having an average diameter of about 2 to 3 millimetres and containing at least 1 viable encysted protozoan, such as a sporulated oocyst of a species of coccidium infective to poultry, each beadlet having a protective coating of animal feed, cement and/or gypsum, the protective coating having an average thickness of about 0.2 to 2mm.
