Newsweek reports American Airlines, United and digital health nonprofit The Commons Project Foundation created their own vaccine passport applications. Brookings Institution Nonresident Senior Fellow John B. Morris Jr. expressed concern over the sharing of health information and increased cybersecurity risk to personal healthcare data being stored. It is “critical” for private entities offering such applications to ensure “that it’s not marketing the data for other purposes, and that the only purpose is to validate your vaccination status,” he said.
