Microsoft Corp, health insurer Cigna Corp and the Mayo Clinic are part of a coalition pushing for digital records of people who get vaccinated against Covid-19.

A key aim of the project, called Vaccination Credential Initiative (VCI), is to help people store encrypted digital copies of their immunisation records in a digital wallet of their choice, the companies said in a joint statement on Thursday.

“VCI’s vision is to empower individuals to obtain an encrypted digital copy of their immunisation credentials to store in a digital wallet of their choice,” according to a press release from VCI. Those who do not want to use a smartphone, or who do not have one, could receive a document with QR codes containing similarly verifiable credentials.

VCI says it is working to make the credentials using the SMART Health Cards specification, which is designed to let people store immunization or lab results in a digital wallet.

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 organisations such as hospitals and pharmacies that are administering the vaccines, said Brian Anderson from Mitre Corp, one of the members of the initiative.

Other companies that are part of the initiative include Salesforce, Oracle Corp and Cerner Corp .

In the United States, where vaccines from Pfizer Inc and Moderna Inc have been authorised for emergency use, vaccinated individuals receive a vaccination card or printout.

The current system does not readily support convenient access and sharing of vaccination records, the companies said.
