Vaccine forgeries are a big problem, especially in developing countries. Valoa offers a quick way to detect a non-authentic vaccine or other injectable: a table-top device that measures six parameters of the vial and its contents. The results are compared to a previous calibration, and if they are within chosen tolerances, a green light is displayed. Optionally the name of the vaccine is displayed as well. Since the vial is not opened, the test is very quick – and no vaccine is lost in a chemical analysis.
When the device is used at a vaccination site, the green light has a confidence-building effect.
The device can be used throughout the chain of delivery, from the manufacturing site to the vaccination site.
