From an Age article a few days ago:”Vaccination walk-ins were halted on Monday with people told to wait until the end of the week as the state government cut the number of Victorians able to get the Pfizer jab as part of the state’s vaccine rollout.
Almost three weeks after the state’s rollout of the Pfizer vaccine was extended to 40 to 49-year-olds, supply caps meant people were unable to make phone bookings for their first dose and those who walked up to mass vaccination hubs were turned away.”
