"At what point might international travel be allowed again?
Vaccination is likely to allow us all to travel again. Certificates will probably be required at border controls, just as they are for yellow fever in countries where the disease is endemic. They will probably become necessary to set foot on an aircraft. Some airlines, such as Qantas, have already said they will require a vaccination certificate from all passengers. “I think that’s going to be a common thing talking to my colleagues in other airlines around the globe,” said Alan Joyce, the Australian airline’s boss. There will be people who cannot be vaccinated, so some sort of formal exemption certificate will be needed for them."
Just saw this in an article online.. if they really are anti-vaccination like a lot of us have assumed then it'll make it very hard for them to travel in the future!
