Britain's Early COVID Vaccine Rollout Reduced Support for EU Policies

Why Cross-Border Performance Shapes EU Support

Irene Rodríguez, Toni Rodon, Asli Unan, Lisa Herbig, Heike Klüver, and Theresa Kuhn ask whether citizens’ evaluations of their country’s performance relative to neighbors shape support for the European Union. Building on a benchmarking argument, they propose that people do not only compare how well their own country performs against other EU members but also against nearby non-EU countries — and that those comparisons can change attitudes toward the EU.

A Natural Test: The UK's Early Vaccine Rollout

The 2020 COVID-19 vaccination campaigns offer a clear test case: the United Kingdom began vaccinating weeks before most EU countries. That timing created an unexpected contrast that could shift citizens’ perceptions of the EU’s effectiveness without the usual confounders of long-term opinion change.

Data and Research Design: Eurobarometer and an Unexpected Event During Surveys (UESD)

The authors exploit Eurobarometer survey interviews conducted around the start of the UK rollout using an Unexpected Event during Surveys Design (UESD). This design compares respondents interviewed just before and just after the UK’s early vaccine start, leveraging the abrupt timing to identify the causal effect of a non-EU neighbor’s superior performance on EU attitudes.

What the Analysis Finds

• The UK’s faster vaccine rollout produced a statistically significant decline in specific policy support for the EU — for example, assessments of the EU’s handling of the vaccine situation and support for EU-level policies.
• By contrast, the same shock did not produce consistent changes in diffuse support (longer-run attachments to or identity with the EU).

Implications for European Integration and Performance Legitimacy

These results suggest that cross-border benchmarking against non-member states can weaken support for supranational policies when those outsiders outperform the EU on salient tasks. The study highlights a mechanism through which short-term performance lapses — relative to visible comparators — can erode confidence in EU policy competence while leaving deeper attachments unchanged. The findings inform debates about EU legitimacy, crisis management, and how comparative performance affects public backing for integration.
