For thos of you who have not seen it, there is a very interesting and useful peer-reviewed paper on "Single versus Multi-Dose Vaccine Vials: An Economic Computational Model". This can be seen on
http://www.technet21.org/index.php/documents/view-document-details/1367-single-versus-multi-dose-vaccine-vials-an-economic-computational-model.html.
The conclusion of the paper is not suprizing:
"Lower patient demand favors fewer dose formats (i.e., the cost of vaccine wastage often may outweigh that of added medical waste and storage requirements), while higher demand favors greater dose formats." but the way the authors review the impact of vaccine storage costs, the cost of vaccine vials, and the costs of the vaccine itself and wastage with different immunization session sizes is, as far as I know, new.
