A key aim of the project, called Vaccination Credential Initiative, is to help people store encrypted digital copies of their immunization records in a digital wallet of their choice, the companies said in a joint statement on Thursday.
These records could eventually be used, with an individual's consent, by colleges that are trying to re-open or even for entry into concerts in the future, Joan Harvey, an executive at Cigna unit Evernorth told Reuters.
The coalition wants to provide governments and employers access to a "solid, widely accepted verification program" that could help them bring people back to work and resume public events, Harvey added.
The coalition has initially partnered with organizations such as hospitals and pharmacies that are administering the vaccines, said Brian Anderson from Mitre Corp, one of the members of the initiative.
The current system does not readily support convenient access and sharing of vaccination records, the companies said.
Individuals without smartphones would receive paper-based QR codes which link to their vaccine records.
