The federal government f'ed up and failed to get enough orders in last year of enough different vaccines. They relied too heavily on the AstraZeneca one, because it could be made here. They gambled and we lost. However this is a government lead by someone who cannot ever admit to stuffing up, so there is always someone else to blame. Then they have further compounded that problem with an inability to organise a piss up in a brewery, so the roll-out has been a mess as well. Then they are putting out mixed messages about the need to get vaccinated, like saying if you are worried about getting the AZ, there will be Pfizer available later in the year.
