Australia's national carrier Qantas will require future international travelers to prove they have been vaccinated against COVID-19 before flying.

The airline's CEO Alan Joyce said in an interview with CNN affiliate Nine News on Monday that the move would be a "necessity" when coronavirus vaccines are readily available, CNN wrote.

Joyce said the airline was looking at changing its terms and conditions to "ask people to have a vaccination before they get on the aircraft."

"Whether you need that domestically, we will 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," the Qantas chief said.

While Qantas is the first airline to indicate that Covid-19 vaccinations would be a must before travel, others could soon follow suit.

A spokesperson for AirAsia told CNN Travel on Tuesday that once a vaccine is available the airline "will review the requirement for guests to be vaccinated against COVID-19 for international travel."

Air New Zealand said it was "really encouraged by the news around vaccines" and said in a statement that "ultimately, it's up to governments to determine when and how it is safe to reopen borders and we continue to work closely with authorities on this."

"Today borders are double locked. Testing is the first key to enable international travel without quarantine measures," said Alexandre de Juniac, IATA's director general and CEO in a statement.

"The second key is the global information infrastructure needed to securely manage, share and verify test data matched with traveler identities in compliance with border control requirements. That's the job of IATA Travel Pass. We are bringing this to market in the coming months to also meet the needs of the various travel bubbles and public health corridors that are starting operation."

Coronavirus vaccine: Update by developers

U.S.-based pharma giant Pfizer, which jointly with Germany's BionTech is developing a vaccine against the coronavirus, updated the public on a higher rate of vaccine effectiveness.

A primary efficacy analysis demonstrates BNT162b2 to be 95% effective against COVID-19 beginning 28 days after the first dose; 170 confirmed cases of COVID-19 were evaluated, with 162 observed in the placebo group versus 8 in the vaccine group, the companies said in a press release.

The efficacy of the vaccine was consistent across age, gender, race and ethnicity demographics; the observed efficacy in adults over 65 years of age was over 94%.

The safety data milestone required by the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) has been achieved.
