Australians could, in the future, be required to show proof of vaccination to enter pubs, grocery stores and sports stadiums, under a plan being considered by the national cabinet.

Prime Minister Scott Morrison this week said state and territory leaders are in talks about the idea, which would take place under phase B of Australia’s COVID-19 exit plan, when 80% of the population is vaccinated.

Professor Mary-Louise McLaws, a UNSW professor and advisor to the World Health Organisation, says it is dangerous and inaccurate to assume that being vaccinated fully eradicates the possibility of virus transmission.
