Brendan J. Lyons is reporting for the Times Union the rollout of the Excelsior Pass has been plagued with glitches and left many unable to download their digital proof of vaccination. The digital app is designed to allow someone to confirm they have been vaccinated or tested negative for COVID-19. The hiccups in the state's immunization database are causing Excelsior Pass registrants to see the "We couldn't find your pass" screen appears on the registration website. Several factors are to blame including a mix of clerical errors, inconsistent data gathering, and the occasional case of people with identical names, but different birthdates. Gov. Andrew M. Cuomo announced the secure program on March 26 and promoted the voluntary platform as a way to help reopen businesses and event venues. The digital passes have a secure code that can be scanned with a companion app to verify someone has been vaccinated or tested negative. A spokesperson for the state this week said an overwhelming number of the "hundreds of thousands" of people have downloaded the app without issues and that upon the 180-day expiration date a person can retrieve a new pass. The state cited Health Department guidance that directs anyone having problems registering or downloading the app to make sure they are doing so at least 15 days after the date of their final vaccination and that their name, date of birth and ZIP code matches the information from the person's vaccination record.
