Australia has fallen 3.4million doses short of its target of delivering four million Covid vaccinations by 31 March, prompting criticism of the government.
The 85% shortfall comes two days following Brisbane entering another snap lockdown to combat a small outbreak.
Last week the government said the vaccine rollout did not demand urgency given Australia’s low infection rates.
The country has recorded 909 deaths and 29,300 cases since the pandemic began – far fewer than many other nations.
Outbreaks have led to six lockdowns in cities in recent months. Critics say situations like Brisbane’s outbreak show why a quick vaccine programme is still needed.
Australia is currently up to stage two of its four-phase rollout for its 25 million population.
Doses are being offered to people over 70, those in aged care homes, frontline health workers, emergency service workers, Aboriginal and Torres Strait Islander people over 55, and people with underlying health conditions.
Authorities have not specified why the pace has been so slow, but issues such as booking technicalities have been reported. There are also reports that some people are opting to not get the vaccine.
