Abstract
Antigenic parasites are encapsulated in semipermeable polymeric envelope membranes to prepare implant capsules for immunizing an animal against parasitic infection. An animal may be immunized against parasitic infection by implanting into the animal the implant capsule at a location in the animal sufficient to stimulate a protective immune response in the animal to the parasite antigen.
