Thank you very much for taking the time to write this comment @john1981!

The girls are my nieces so the schedule of their vaccinations is up to their parents.

I also appreciate you explaining "herd amunity"- I just looked it up and I think "amunity" was a typo and I think you mean: herd "immunity"? Or am I mistaken?

Either way your comment made me think about something.... Australia's current population is 23.78 million people. Australia currently receives 8.46 million visitors a year. Australia does not require vaccinations to visit and does not vaccinate people on arrival (although it is evident that this would be profitable for the Pharmaceutical companies).

With a yearly influx of almost 30% of the population of potentially unvaccinated tourists I wonder how this impacts "herd immunity"? Does this negate "herd immunity" or Australia should vaccinate on arrival? It would devastate tourism if they insisted on this!

What do you think mate?

Cheers! =)
