The timeline of Covid certificates in France
May 2021, a national Covid certificate, the 'pass sanitaire' was adopted for big events only.
End of June 2021, the pass sanitaire became compatible with the EU Green Digital Certificate.
Mid July 2021, the French government generalized the use of Covid certificates to all public spaces (e.g. restaurants, cinemas, train stations, etc).
End of November 2021, Covid certificates integrated booster doses.
Mid January 2022, Covid certificates are replaced by vaccines certificates.
Our initial proposal in few words (april 2021)
Our initial proposal in few words (april 2021)
A digital health pass can be used to control the risk of a cluster in social gatherings or travels.
We propose a system which is fair and efficient:
People have a 'green pass' when they are vaccinated, immune or have a recent negative test.
Places have a 'green', 'orange' or 'red' code dependent on the conditions of the interaction (outdoors vs indoors, ventilation, density, health protocols)
A simple matching rule for reopening should be fixed by health authorities, such as:
people with a green pass can go everywhere, and essential places are open to everyone
in zones where the virus circulates (orange or red zones), places at highest risk of transmission should adopt a health pass to ensure a safe reopening
