Professor Mary-Louise McLaws, an epidemiologist at the University of New South Wales, said the vaccination rate needs to increase quickly due to the narrow window before a second dose is required.

Australia may not need to administer all 45m doses to stop the virus circulating – a point called herd immunity, which is reached when there is sufficient immunity in the population such that Covid-19 cannot spread. Given Australia’s low number of cases, reaching this point would need to be done almost entirely through vaccines.
