What are the main issues around Vaccine Passports?

The headline is that at present, any use of vaccine passports or health status apps is not justifiable given the lack of evidence on transmission.
2.

The vaccine passport relies on the assumption that my vaccine status tells you something about the risk I pose to you, not simply the risk I face from COVID-19. That’s not something we can currently know.
3.

Add in different vaccine regimes combined with emerging mutations that may impact upon vaccine effectiveness, and it all makes for a complicated picture.
4.

The move towards a system of individualised risk scoring could undermine public health by treating a collective problem as an individual one, and reducing compliance with social distancing, hand hygiene and masks.
5.

Building infrastructure around vaccination could exacerbate distrust by marginalised groups and increase vaccine hesitancy, if this is seen as introducing mandatory vaccination by the back door, or building surveillance apparatus for communities that are already monitored.
6.

Tying movement to vaccine certification could increase inequality nationally, entrench existing global inequalities, and potentially even supercharge vaccine protectionism.
7.

Infrastructure introduced for one purpose might be used for another – and information might flow to third parties or personal data may be repurposed.
8.

This isn’t an issue that can be solved by technical build alone; even the most privacy-preserving technology could be used to share some manifestation of health information or risk score to different actors, from potential employers to insurance companies.
