Visual cue - need to find a pilot country

To update the Multi-Dose Vial Policy, WHO and the Immunization Practices Advisory Committee (IPAC) has been designing a "visual cue". This is a small logo that will be placed on vaccine vials to allow health workers to judge whether to discard the vial at the end of a session, or allow the health worker to keep the opened vial under cold chain conditions. To finalize this however, we would like to pilot test the visual cue in a country. Ideally, this would be done over one year in a developing country that is introducing a vaccine presented in a multi-dose. These vials would be marked with the visual cue, and training provided to health worker on its use. Subsequently, the knowledge and practice of health workers in respet of the keeping or discarding of a vial would be tested. If you know of such a planned vaccine introduction, we would like to see if this country may be able to be selected. Your inputs would be most appreciated.
