Each and every person attending the 2021 Telluride Film Festival (Thursday, 9.2 through Monday, 9.6) needs to carry a coronavirus vaccine certification card (Pfizer, Moderna, Johnson & Johnson). Some kind of laminated driver’s license-sized card with a bar code — one that you can attach to your festival pass. No, such cards haven’t been issued but they clearly need to be to allow certain dormant businesses to reactivate in the summer and fall. Not just film festivals but any business or civic gathering that involves close proximity — indoor restaurants, cinemas, town halls, airlines, convention centers. A 1.18.21 CNBC story reported that “Microsoft, Apple and Google have shown interest in developing vaccine passports or certificates to usher in safer travel.”
