The Prime Minister Scott Morrison has welcomed the updated Australian Technical Advisory Group on Immunisation (ATAGI) advice which strongly urges adults over 18 in Greater Sydney to get any vaccine available to them, including AstraZeneca.

Mr Morrison says 90,000 additional Pfizer vaccine doses will be delivered to New South Wales from next week, amid the state's growing COVID-19 outbreak. 

He also conceded there is brand damage around the AstraZeneca vaccine, but people should consider the evidence around its efficacy.
