UPDATE #1: App developers replied that the CDC (Official) COVID-19 Vaccination Record I described is not the proper format/card. This is NOT exactly correct. The format/card the App requires, is a COVID-19 Vaccination CERTIFICATE, you can obtain IF your provider uses the CDC's VAMS system to record vaccinations. Not all providers are registered (or required) to use VAMS. The 1-sided CDC COVID-19 Vaccination Record Card is still an official CDC-issued document, this App won't scan.
