If your original paper vaccination record was lost or damaged, there is no need to seek out a replacement because that information is now easily available in MyChart.
A QR code can be downloaded and/or added to the login screen of the MyChart app that can be viewed without the need to log in. This QR code can be presented when proof of vaccination is required for entry to events, concerts, flights, travel, etc. This makes it possible to no longer carry the paper copy of your vaccination record.
How to find it: log in to MyChart, click "menu", and look for the COVID-19 virus icon.
