a peristaltic pump for dispensing the at least one first vaccine therapeutic agent;

wherein the device includes at least one metabolite required by at least one auxotrophic microorganism; and

the at least one second auxotrophic microorganism including at least one nucleic acid construct encoding at least one second vaccine and located in a second compartment;

wherein the first and second compartments are configured to release the first vaccine prior to the second vaccine.

2. The device of claim 1, wherein the at least one metabolite required by at least one auxotrophic microorganism resides on the surface of the semi-permeable barrier.

3. The device of claim 1, wherein the at least one metabolite required by at least one auxotrophic microorganism is located in a compartment configured to dispense the at least one metabolite to the interior region of the at least one semi-permeable barrier.

4. The device of claim 1, wherein the at least one metabolite required by at least one auxotrophic microorganism is embedded in the at least one semi-permeable barrier.

5. The device of claim 1, wherein the at least one metabolite required by at least one auxotrophic microorganism is released as at least a portion of the at least one semi-permeable barrier degrades.

6. The device of claim 1, wherein the metabolite includes at least one energy source, nutrient, or other metabolic pathway requirement.

7. The device of claim 1, wherein the at least one semi-permeable barrier is structured to facilitate egress of the at least one therapeutic agent.

8. The device of claim 1, further including at least one tissue-anchoring component.

9. The device of claim 8, wherein the at least one tissue-anchoring component includes at least one latch, hook or tether.

10. The device of claim 1, wherein the at least one auxotrophic microorganism includes at least one population of auxotrophic microorganisms.

11. The device of claim 1, wherein the semi-permeable barrier includes a bone cage.

12. The device of claim 1, wherein the semi-permeable barrier includes a diatom cage.

13. The device of claim 1, wherein the semi-permeable barrier includes at least one component configured to selectively limit access between the interior and the exterior of the barrier.

14. The device of claim 1, further including at least one sensor.

15. The device of claim 14, wherein the at least one sensor is configured to sense at least one biological cell or material.

16. The device of claim 14, wherein the at least one sensor is located in the interior of the semi-permeable barrier.

17. The device of claim 14, wherein the at least one sensor is located exterior to the semi-permeable barrier.

18. The device of claim 14, wherein the at least one sensor includes an optical density sensor.

19. The device of claim 1, wherein the semi-permeable barrier is configured to actively or passively transfer at least a portion of the at least one therapeutic agent to the exterior of the barrier.

20. The device of claim 19, wherein the semi-permeable barrier is configured to actively or passively transfer at least a portion of the at least one therapeutic agent based on at least one chemical gradient.

21. The device of claim 1, wherein the at least one semi-permeable barrier includes at least one of an emulsion, lipid, dispersion, or micelle.

22. The device of claim 1, wherein the at least one semi-permeable barrier includes one or more cells.

23. The device of claim 1, wherein the at least one semi-permeable barrier includes one or more cell junctions.
