This new correlational study by Porat et al. found that that the more people felt they themselves had control & the authorities understood their needs, the more willing they were to get vaccinated and their actual vaccine status.

If vaccine passports were perceived to frustrate these needs (for autonomy and relatedness), therefore, we'd expect passports to de-motivate people from getting vaccinated.

In line with this expectation, the researchers found that the sample from Israel (has vaxx passports) had more autonomy-frustration and relatedness-frustration than the sample from the UK (doesn't have vaxx passports)

It was only a correlational study. BUT the idea that the meaning of vaxx /passports (e.g., 'a form of coercion') might impact on intentions to get vaccinated has been evidenced in previous (pre-covid) research, covered in our recent rapid review

More recently, this experiment by @ReicherStephen @ProfHeidiLarson & de Figueiredo provided further evidence of backfire effects...

They found that while vaxx passports could increase motivation to get vaccinated among some groups, among those with low trust in the authorities (e.g., minorities), the opposite was the case.

Other risks for vaccine passports (and other forms of covid health certification) include inequalities/ social exclusion (the major problem), self-infection (already happening in France), and complacency over test results.

Conclusion:
Vaxx passports are one possible solution to the problem of opening up safely. But their multiple problems means we should look instead to other solutions:
Public engagement with the vaxx programme
Support for self-isolation
Masks & distancing
Reliable testing

PS These comments refer to domestic 'vaccine passports'. Surveys find that vaccine passports for international travel are less controversial and supported by more people: bmcpublichealth.biomedcentral.com/articles/10.11…
