'Vaccine passport' needed to fly?

While coronavirus vaccines are distributed around the world, a Geneva-based nonprofit is teaming up with airlines and The World Economic Forum to create a "vaccine passport" app to ease air travel during the pandemic. They say the digital credentials can also be used at stadiums, movie theaters and offices. According to developers, users will receive a private QR code once test results or proof of vaccination are uploaded. IBM has developed a similar app, Digital Health Pass, that lets companies and venues customize what they require for entry to a physical location.

• The holidays have seen a sharp increase in air travel: The Transportation Security Administration reports it screened a pandemic record of 1.28 million people on Sunday.
• Dozens of countries have imposed restrictions on travel from the U.K. to curb the spread of a COVID-19 variant that led to a tougher lockdown in London and southeast England.
