Tracking proof of vaccination

Hello,

We are going to be requiring that patrons provide proof of vaccination or a negative test to attend our larger donor and member events. Has anyone started this yet? Looking for tips in how to execute this for both big and small events.

Also, wanting to know if anyone is tracking proof of vaccination with Tessitura. Asking because we have many donors that will attend multiple events so not sure if there is a way for them to provide that information once for the entire season, then we don't have to have them show it for every event.

Thanks!
Michelle
