Without a clear medical understanding of mRNA Technology - at least knowing its chemical formula as a drug, it would be impossible as a policy for the Australian Government to accept any such solution as a viable 'medication' - even at the time of Pandemic. Just because it is a Pandemic, does not authorize the Australian Government to administer an un-authorizable, un-tested and un-verified drug onto its Citizens. The Pandemic does not provide any 'excuse' to validate an untested drug, and hope that it solves any issue. The risk inherited by such suggested uptake of mRNA Drug, is that Citizens may fall sick years after its administration, and where their General Physicians and Specialists in Australia, would not know how to diagnose, post subjection of the Patients to such unknown and un-qualified medications.
The best action the Australian Government can take, is to make compulsory, the best 'available and verified' drug in Australia, that is administered for such symptoms of Influenza. The rest of the chance, as it belies, would be most suitably mitigated with a path that offers a Known Science, as opposed to an option of Unknown Science, such as that of the mRNA Technology.
