I disagree. Vaccine passports are only relevant if you still have high community spread but you want to allow those who are vaccinated to get on with normal life. I know I am being quite an optimist, but I believe that is going to become a moot point in short order. I think by this summer, from a combination of the number we have vaccinated plus those who have natural immunity from having had Covid, you are going to see community spread drop low enough that we can just drop the mitigation measures altogether and not worry about anything like vaccine passports. I really believe the end of the pandemic is near.
