The problem we solve: Counterfeit COVID-19 vaccines have shown up in at least 16 countries. This device checks the vaccine without opening the vial and alerts if a forgery is found. The measurement takes only seconds, so every vial can be checked at the vaccination site.
About our solution: The device is a combined refractometer and nephelometer. The vaccine vial is not opened. First, a reference vial is measured, and the readings are saved. Then the unopened vials to be tested are inserted one at a time and measured. Both readings must be close enough to the reference readings for the vial to be accepted. If the readings differ more than a preset amount, an alarm is sounded and displayed. An optional wireless module sends an alert to a central location.Progress to date:
The refractometer and the nephelometer have been separately tested and patented. In this project, they will be combined into one device, using one common light source. A provisional patent application for the combination device has been filed.

The knowledge that this technology exists will make patients more confident that they are getting the right vaccine.
Providers will feel good about the vaccines they administer, because they have the means to verify them.
Hospital management and staff will be confident that no bad vaccines will go into their patients.
