JP Pollak, PhD, Chief Product Officer, The Commons Project. Major airlines will soon roll out apps to check the COVID-19 test and vaccination status of passengers, likely followed by employers, college campuses, sports venues, and cruise ships. CommonPass, developed by the non-profit Commons Project, lets individuals access their lab results and vaccination records, and consent to have that information used to validate their COVID status without revealing any other underlying personal health information. Lab results and vaccination records can be accessed through existing health data systems, national or local registries or personal digital health records (Apple Health for iOS, CommonHealth for Android). The CommonPass platform assesses whether the individual’s lab test results or vaccination records come from a trusted source and satisfy the health screening requirements of the country they want to enter, while the underlying health information stays in the individual’s control. JP describes the process for integrating this information into the app and its rate of adoption to date.
