Dismiss 12.17pm Normal text size Advertisement Queensland’s Chief Health Officer says “now is the time” for people younger than 60 to speak to their GP about getting the AstraZeneca vaccine if they can’t get a dose of Pfizer. Jeannette Young has come under fire from interstate and federal authorities over her stance on the AstraZeneca vaccine, which she has said should not be used by anyone under 40 and only by those under 60 after speaking to their GP. She reiterated that stance on Monday, despite growing case numbers in south-east Queensland thanks to an outbreak involving several school communities with the highly transmissible Delta variant.
