If you're hoping your next vacation involves riding around in a kangaroo pouch, or whatever they do in Australia, for at least one airline you're going to need to prove that you've been vaccinated for Covid first.

Australian airline Qantas has announced that they are planning to require international travelers to have received the new coronavirus vaccine before flying with them.

Qantas CEO Alan Joyce said,

"Whether you need that domestically, we'll have to see what happens with COVID-19 in the market, but certainly for international visitors coming out and people leaving the country, we think that's a necessity."

Mr. Joyce expects other airlines to have a similar requirement,

"I think that's going to be a common thing talking to my colleagues in other airlines around the globe."

How might such a requirement be enforced? He suggested perhaps the creation of a digital "vaccination passport" could do the trick. It would show what vaccines you've received and if they are "acceptable to the country you're traveling to."

This comes as Pfizer, Moderna and AstraZeneca have all said their vaccine candidates have proven effective in fighting the virus. And Pfizer's may be available in the US by the end of the year.

Does the prospect of airlines mandating what you have injected into your body make anyone else nervous? Or am I the only fan of bodily autonomy here?
