The US should have introduced Vaccination Passports from the beginning to allow vaccinated travellers to visit the US [Reader Opinion]

✉️ [From Reader: Frank G]
Vaccination Passports should have been introduced by President Biden from the beginning, I am sure the US would have opened up by now. It amazes me that other countries have implemented it yet somewhere as modern and forward thinking as the US has not. The damage this travel ban has done is unrepairable however the best thing would be for Biden to allow vaccination passports so that those from Europe could visit.
