In that particular interview, I tend to agree. However I've seen/read multiple other interviews and talk shows where EU politicians talk quite differently. They may admit some general mistakes (without naming one) but still dispute each and every critic.

In one talk show for example a representative of the European Commission at least mentioned twice that in Africa even less people got vaccinated than in the EU. Like this would be the frame of reference.

Well, really owning up to a mistake that will cost a few tens of thousands of lives would at least be a resignation.
