I agree that we will need to reach 90%+ of 5YO+ with current vaccines to be able to go back to a pretty much normal life with low risk to the general public.
What I’m less sure about is whether we can or will maintain restrictions for the unvaccinated. Most of Europe and US dropped those requirements very quickly even if holding onto them would have been a benefit. Whether it was simply too hard to back up legally, or too hard to enforce, I’m not sure, but I don’t think they dropped those requirements for no reason. I hope we do hold onto restrictions for unvaccinated longer than others did. I’m just not sure we will.
We have already announced that we’re moving away from booster shots for the whole population, and just planning to implement them for vulnerable groups, so we can instead reserve them for poorer countries who haven’t had the chance to be widely vaccinated. I’m a little conflicted about that stance. It clearly seems the right thing to do both from a humanitarian view, as well as it being likely to help reduce incidence of worse variants in future. I do wonder, though, whether holding back boosters from a relatively small population like Australia might hamper our own daily life and economy enough to divert our focus away from concentrating more of our efforts on world needs. I just wonder if being less selfish could hamper our capacity to give more over the next few years. It’s like the announcement on planes about applying your own oxygen mask first, before helping others. Our instinct is to prioritise children before us, but doing so may ultimately do more harm to them and us if we become incapacitated.
