BRUSSELS/LONDON—EU officials confessed on Saturday to a “blunder” in invoking Northern Ireland Brexit emergency powers during a showdown with Britain over vaccines, and London said it expected its supply of COVID-19 shots would not be interrupted.
The European Union has fallen far behind Britain and the United States in the race to vaccinate its public. It announced on Friday it would impose export controls on vaccines, widely seen as a threat to prevent doses from being sent to Britain.
