However, you are still protected against severe disease/hospitalisation when vaccinated. They reckon, they will need booster shots for the elderly after about 8 months - this is what Germany is planning - but the younger/healthy ones will be fine. As long as Covid is circulating in the community, the immune system of vaccinated people will get natural boosters (as most of them will have no or little symptoms when infected). Then, there is the option of "mix and match" vaccines to increase effectiveness (some countries are recommending this already). And one day, the 2nd generation of vaccines will likely be more effective against the Delta variant as well.

I know 2 people here who recently caught Covid (Delta variant) despite being vaccinated - one person had Pfizer (in January), the other one AZ (2nd jab in May/June). The AZ guy had underlying issues (COPD, lung cancer) so Covid could have been a death sentence for him. Instead, he spent a week at home in bed, feeling crook but didn't need to be admitted to hospital. Exactly what the vaccines are supposed to do.

Yes bring on the second generation. Any ideas when next gen recipes are coming?

Pfizer/Biontech will submit more data regarding the efficacy of booster shots shortly.
Regarding an updated version:
"While Pfizer and BioNTech believe a third dose of BNT162b2 has the potential to preserve the highest levels of protective efficacy against all currently tested variants including Delta, the companies are remaining vigilant and are developing an updated version of the Pfizer-BioNTech COVID-19 vaccine that targets the full spike protein of the Delta variant. The first batch of the mRNA for the trial has already been manufactured at BioNTech’s facility in Mainz, Germany. The Companies anticipate the clinical studies to begin in August, subject to regulatory approvals."

But even if efficacy is waning, it still appears that the shots largely protect against severe illness, which is the primary goal of vaccination.
Breakthrough infections appear to be increasing, but even in the face of Delta, the existing vaccines are still extremely protective.

Full vaccination is still effective at preventing hospitalisation and death despite the virus having slightly changed its structure, but it seems that so far it has not been enough to trick the vaccine-elicited immune response.

Also, Delta won't be the last variant we'll encounter. If there was an updated vaccine every time we deal with a new variant, it eventually would get too confusing and foster vaccine hesitancy.

The best protection against new variants is high vaccination rates across the globe as variants will always develop when the virus is allowed to run free. That's why it makes more sense to push for a quick global vaccine-roll out and distribution rather than offer 3rd booster shots in rich countries.

In essence...Covid will become part of our life. It will be interesting to watch once WA and QLD wake up to this new world as they're definitely not prepared. No matter how high your vaccine coverage is amongst your population, there won' t be zero cases.

How long they can keep that up for is going to be quite a spectacle. Especially if NSW lets overseas people in with a clear Covid test and no Quarantine. That's even going to be a challenge for far more moderate Victoria to come to grips with. Public opinion in the rest of Australia seems hell-bent on zero Covid.... I'm fairly concerned about getting the living with Covid message through to Victorians at present. Different mindset in Victoria, the public there have basically been in a full-scale personal battle with Covid, trying to do their bit to beat it. and doing quite well in that battle. Living with Covid for a lot of them will mean that fight was in vain and hard for a lot to admit defeat.

So people are having to fly back to Vic or NSW, with nowhere to live no jobs etc. The directive was brought in with 2 hours notice. No one will be leaving Queensland in the near future cos they could find themselves locked out of their homes for the duration.

At $3000 per stay surely giving them some income is the right thing to do. Delta will come in. It's just a matter of time. I feel for the travel industry. It's going to take a long time for the rest of Australia to trust a holiday to Queensland again.

SImilarly, we have been putting people on buses to Cairns from Townsville, sometimes 50 a day, or putting them on a plane to Brisbane, because there are noi quarantine hotels in Townsville. People stared at me in disbelief when I said Why don't we sign up a Townsville hotel and save thousands in transport fees. And all those people have to be returned to Townsville at the end of their quarantine. Spending money like water, and no logic to it.

I agree with your last statement. Many people just won't come to Queensland again in case of more sudden decisions. Death knell for many tourist operators.

Across Australia, in the 14 months between April 2020, and June 2, 2021, there have been 21 hotel quarantine breaches, some of which have led to disastrous health consequences, and corresponding lockdowns (notably, but not limited to, Victoria's first big Alpha-strain outbreak of a year ago).

That's a long-sustained record of failure for hotel quarantine in general, across Australia. Hotels are not designed to limit room-to-room airflow through their HVAC systems, nor to provide an environment conducive to limiting (quarantined) guest interaction, especially with minimally motivated/compensated rent-a-guards in charge.

A sensible state government would respond by building bespoke quarantine facilities with (belated but useful) federal help, and by limiting further reliance on "hotel quarantine" to the extent possible, given that approach's well-documented record of public-health failure and risk.

Does she honestly expect us to believe that garbage?

The NRL bubble exists so a pampered bunch of 1 percenter entertainers (sorry, er, athletes) can continue to ply some semblance of their trade, to the benefit of themselves, and the TV rights holders who make money off them. Good for them, in some ways, and I also cynically get the "bread and circuses" angle for the pollies that have supported it.

But to suggest that the NRL bubble is "tightly controlled" is ludicrous, given the number of brazen breaches that have made the headlines over the past weeks and months. (Note that this latest extension of the 'bubble' is defended by QLD pollies as "self-funded" -- but it is also apparently "self-policed". Guess how tight *that's* going to be...)

And to suggest that wantonly extending the bubble, to NRL family, agents, camp-followers, or whoever, is reasonable at a time when members of the "general public", even those with far more profound family and/or business interests in QLD, are denied access, is just appalling.
