Australia has received 300,000 doses of the AstraZeneca PLC vaccine, more than doubling the amount of all vaccines shipped to the country so far and allowing the government to ramp up its Covid-19 immunisation drive.

“We will now be able to scale up the vaccination rollout to our priority groups, including our most vulnerable Australians and to our frontline border and health workers,” Prime Minister Scott Morrison said in a statement, according to Reuters.

Up to four million Australians are expected to be inoculated by March, with Morrison being among a small group receiving the first round of the Pfizer/BioNTech vaccine.
