SYDNEY: Australia will buy 10 million additional doses of the COVID-19 vaccine jointly developed by US drugmaker Pfizer Inc and Germany's BioNTech , Prime Minister Scott Morrison said on Thursday.

"These additional vaccines have been secured consistent with our requirements," Morrison told reporters in Canberra.

Australia last week approved the Pfizer-BioNTech COVID-19 vaccine for use for people aged 16 years and older, and expects to begin inoculation at 80,000 doses per week by the end of February.
