Abstract
Abstract Ballistic projectile containing an antigen and method for inoculating animals comprising the non-lethal, ballistic implantation of a projectile containing antigen totally within a living animal. Following implantation, the antigen is released in situ in the animal in response to the fluids and cells of the animal body.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
62 words
A ballistic implant shaped for penetrating the epidermal covering of a living animal body and lodging totally within the tissues of the animal body, said implant consisting essentially of a biologically compatible polymer body and an antigen contained within the polymer body in a manner permitting release of said antigen in response to the fluids and cells of the living animal body.
Claim 2
Dependent Claim
62 words
A ballistic implant shaped for penetrating the epidermal covering of a living animal body and lodging totally within the tissues of the animal body, said implant consisting essentially of a biologically compatible polymer body and an antigen contained within the polymer body in a manner permitting release of said antigen in response to the fluids and cells of the living animal body.
Claim 3
Dependent Claim
23 words
A ballistic implant according to claim 1 wherein said antigen is contained within a cavity opening to the rear of said polymer body.
Claim 4
Dependent Claim
16 words
A ballistic implant according to claim 2 wherein said cavity is sealed by a removable cap.
Claim 5
Dependent Claim
15 words
A ballistic implant according to claim 1 which includes ballast means within the polymer body.
Claim 6
Dependent Claim
15 words
A ballistic implant according to claim 1 wherein said antigen is in a solid form.
Claim 7
Dependent Claim
23 words
A ballistic implant according to claim 1 wherein said polymer body is soluble in the fluids and cells of said living animal body.
Claim 8
Dependent Claim
17 words
A ballistic implant according to claim 6 wherein said antigen is distributed throughout the soluble polymer body.
Claim 9
Dependent Claim
15 words
A ballistic implant according to claim 6 wherein said soluble polymer body comprises hydroxypropyl cellulose.
Claim 10
Independent Claim
65 words
A method of inoculating living animal bodies with an antigen, said method comprising ballistically implanting totally within the tissues of said animal body a ballistic shaped implant consisting essentially of a biologically compatible polymer body and an antigen contained within the polymer body whereby said antigen is released in situ in said animal body in response to the fluids and cells of said animal body.
Claim 11
Independent Claim
65 words
A method of inoculating living animal bodies with an antigen, said method comprising ballistically implanting totally within the tissues of said animal body a ballistic shaped implant consisting essentially of a biologically compatible polymer body and an antigen contained within the polymer body whereby said antigen is released in situ in said animal body in response to the fluids and cells of said animal body.
Claim 12
Dependent Claim
20 words
A method according to claim 9 wherein said antigen is selected from the group consisting of vaccines, bacterins and toxoids.
Claim 13
Dependent Claim
14 words
A method according to claim 9 wherein said antigen is in a solid form.
Claim 14
Dependent Claim
22 words
A method according to claim 9 wherein said polymer body is soluble in the fluids and cells of said living animal body.
Claim 15
Dependent Claim
13 words
A method according to claim 12 wherein said polymer body comprises hydroxypropyl cellulose.
