I believe that other governments will eventually relax their rules. Tests will likely remain for the foreseeable future, quarantines will also remain in some countries for the time being.If the EU and UK still want vaccine passports, then it is going to be an interesting time ahead when things start to reopen.
How will you prove you are vaccinated if your country does not have a proper "vaccination passport"?
Cruises especially seem problematic.
The DR is keeping a data base. We asked and they said yes they are. After the second vaccine dose earlier this week, they told me to laminate my vaccine card.
Cruise lines certainly will be problematic............as they have shown to be in the past with mysterious outbreaks involving Legionnaires disease etc. They will likely continue to require a certificate of vaccination to travel.............
