Macron: EU vaccine failure because it didn't 'shoot for stars'

European Union leaders are struggling to speed up vaccinations, trailing countries like Britain and the United States and facing supply delays.

Macron himself has been criticized at home for a faltering rollout which has been slowed by bureaucracy and public mistrust of vaccines.

The EU tightened its oversight of coronavirus vaccine exports on Wednesday, giving it greater scope to block shipments to countries with higher inoculation rates such as Britain, or which are not sharing doses they produce.
