We can talk about how more than 98% of the entire population of Australia happily took two to three COVID vaccinations over the course of the past two years or so and there's been no significant increase in morbidity and mortality statistics compared to before.

We can talk about how Australia has some internationally acclaimed epidemiologists who have been trawling the statistics here for the past 40 years, publishing ground breaking work on folate for infants, SIDS, disease studies, etc. and yet have (at least according to your premise) utterly failed to identify any better health outcomes for the unvaccinated Vs the vaccinated in four decades of data on flu outcomes.

Exactly what kind of numbers are you expecting to see in an island population of 22+ million over four decades?
