As vaccination speeds up and governments are eager to return to a sense of normalcy, the concept of vaccine passports has gained significant traction among policymakers and business leaders. The EU Commission proposed a 鈥渄igital green pass鈥� for travel in Europe and the U.S. government is eyeing a similar approach. Vaccine passports or certificates would allow businesses and countries to better track and distinguish between those who are vaccinated and those are not, and give the fully-vaccinated more access to activities that are still deemed problematic (travel, large gatherings such as concerts, sport events, etc.). But vaccine passports are not an easy solution. They come with significant drawbacks that could exacerbate inequality and discrimination against vulnerable groups.

Join us for a discussion with transatlantic experts on April 8, 10AM ET/4PM CET about the prospects for vaccine passports, ethical and legal concerns, and practical ways to implement them.

Quotes

Ron Roozendaal, Dutch Health Ministry

鈥淭rust and interoperability are crucial.鈥�

鈥淲hat can you expect entering the European Union this Summer? First of all, we will have a unified, interoperable Green Certificate for the EU citizens, and they can show that while entering. (鈥�) What we try to do now is come to an interoperable framework internationally, outside the Union also.鈥�

鈥淚s there debate? Yes, there is a lot of debate in the Union. It鈥檚 about trust, mainly. (鈥�) What we try to do is use the digital possibilities to enhance the situation. For example, it is possible to come up with a digital certificate that does not enable persons being tracked around their visits in other countries. You can do that by changing QR-codes every few seconds. You cannot change a QR-code that has been printed on paper. So what we try to do is come up with a more privacy preserving way of doing this in a digital society, to enable people trusting.鈥�

Melinda Mills, University of Oxford

鈥淥ne thing we plead for are internationally standardized criteria, because we鈥檙e a global world.鈥�

鈥淚n the UK and the US we have very polarized societies and it鈥檚 often connected to civil liberties, and I think we have to really realize how people are seeing this and we have to engage with them about how this isn鈥檛 about your rights, this is about protection, and this isn鈥檛 about tracking鈥� And, you know, I think we can鈥檛 underestimate that narrative.鈥�

鈥淐ovid has revealed deep inequalities in many of our societies and we just have to be really clear if there is vaccine hesitancy among certain ethnic groups, or pregnant women don鈥檛 get vaccinated or people don鈥檛 get tests for different reasons, we really have to clarify (鈥�) what鈥檚 in place for those people that aren鈥檛 able to do these tests or have a vaccine.鈥�

Deanne Kasim, Change Healthcare

鈥淲e realized that privacy and equity were absolutely the things that needed to be preserved for this.鈥�

鈥淲e realized (鈥�) that there could be a need for this, similar to your boarding pass, that you have a QR code to get on an airline 鈥� but how do we take that to a place which is preserving privacy, that doesn鈥檛 live on somebody else鈥檚 server and that really is up to the consumer?鈥�

鈥漌hen the vaccines rolled out we all got our paper card. (鈥�) The whole idea of the credential was to put that white card digital, but also to preserve privacy, and I think that鈥檚 something that we have looked to bake into these apps, but as these mature, that continues to be a thread throughout the fabric.鈥�

Brian Behlendorf, Linux Foundation

鈥淭here鈥檚 been recent advancements in cryptography and mathematics that are much better aligned with this idea of being able to prove a thing without having to show a lot of information about that thing. Kind of the equivalent of if I do go to a concert and I show my driver鈥檚 license, the person looking at that license, if they have limited it to people over the age of eighteen, they鈥檙e not writing down my birthday 鈥� they鈥檙e just looking to see 鈥榠s this person over eighteen? Okay, great, they can go in鈥�. That same kind of zero-knowledge system and zero-knowledge proof needs to be something that we standardize across the system and make really meet up with the users鈥� expectations of how these systems should work. They should work like paper.鈥�

鈥淭hese passport systems, these pass systems, these wallets, as we prefer to call them, need to be trusted more like the way that consumers trust their mail client or their web browser, than the way that they might trust their Uber app sitting on their phone.鈥�

鈥淚f any of these efforts, the health pass and the stuff that we work on at the COVID Credentials initiative come to bear fruit, you will see a second wave of apps that are more interoperable, that are more about management of certificates, about putting more power in the consumer鈥檚 hands and true interoperability.鈥�
