Australia has fallen far behind its target for Covid-19 vaccinations, according to recent figures, with only about 670,000 people inoculated against an initial target of four million by end-March.

Reuters reports that the slow rollout, which puts Australia behind many other developed countries, has been blamed by the government on supply issues from Europe, while recent floods across the east coast have slowed the delivery of vaccines.

State governments have also complained about slower-than-expected distribution and a lack of certainty on supplies, while local media have reported errors by private contractors hired to assist with the rollout.
