Wowsers, 25,000 cases a day?

2021/12/15

As COVID numbers continue to rapidly increase in NSW - likely due to the Omicron variant - we're being warned that modelling is pointing to 25,000 cases a day by the end of January.Yesterday, NSW Health Minister Brad Hazzard talked about modelling by the University of NSW which said case numbers could reach heights not seen before in Australia.And it comes as NSW continues to let its foot off the restrictions brake, redefining what a close contact is.So is what is happening there likely to happen

There was a large jump in COVID cases in NSW yesterday, and while we're largely moving on from day to day case numbers - this one is worth talking about.Why? Well, there's a new variant in town and health authorities are already suggesting that we can expect far more from Omicron in coming weeks.The same goes for other states and territories - like Victoria which still has higher daily figures than NSW, but hasn't yet seen a big jump.So on today's Coronacast what should we make of the rising

After nearly two years of constant internal border changes, by the end of this week large parts of Australia will once again be open for domestic travel.South Australia opened a few weeks ago, Queensland opened yesterday and Tasmania is due to open tomorrow. Western Australia has also finally given a date and will reopen on the 5th of February next year.So with state and territory bubbles bursting all over the place, what might come next for people who live there?Also on today's show:* How is

Why is the Moderna booster a half shot?

2021/12/12

Australia now has two different booster options to choose from when the inevitable time comes for the third dose of coronavirus vaccine.Moderna was approved by the country's vaccine expert group ATAGI over the weekend.We'll also be able to get the booster a month earlier, with the Government announcing a shorter period due to the threat of waning immunity and new variants.So if Moderna is a choice, should you take it over Pfizer? Does it even matter? And why is the Moderna booster only a half

All roads lead to third doses

2021/12/09

As the data from initial studies into how Omicron evades our immunity continue to flow in, it's becoming more and more likely that a third dose - or booster - is going to be essential.Several more studies have been released, all showing large falls in immunity to the Omicron variant.One thing that the studies imply though is that there are much higher antibody levels in people who have either been infected, or received a third dose.So how much will third doses be needed to combat Omicron?Also on

Omicron evades vaccines, but not all is lost

What"s That Rash? ·

2021/12/08

One of the first studies into Omicron and immunity has reported back and it's not super great news: there's significant evasion of antibodies produced by the Pfizer vaccine.But not all is lost. The study says that the Omicron variant uses the same way of getting into our cells, meaning our existing tools and techniques should be relatively easy to change so they work better. The study is not yet published, and is a very small sample size so it's worth keeping in mind that this is still a very new

Do vaccinated people get long COVID?

2021/12/07

Beyond the nasty and sometimes life-threatening symptoms that COVID can bring, there's another risk: long COVID. It's the collection of prolonged symptoms including brain fog, smell loss and fatigue.And while we know that being vaccinated drastically reduces your risk of a bad bout of COVID itself, a lingering question has been whether it also protects you from long COVID. Well, according to a yet to be peer reviewed study, the answer is yes it does. Also on today's show:* Is there any research work

Over the next several months, the fight between Delta and Omicron is going to be scientifically fascinating. In the red corner is the current world champion Delta, which easily beat out every other variant of concern to date. In the blue corner is the challenger Omicron, whose continued existence probably relies on its ability to beat out the champion. But how will we know who's winning and when will we get a better sense of it all? Also on today's show: * What makes a virus go viral? * Who

It's been a bit more than a week since we learned of Omicron, the newest coronavirus variant of concern.And while we're still a while from knowing solid answers, the world's scientists have done an amazing job over the last 7 days unraveling parts of Omicron's mysteries.The three big questions are will our vaccines continue to work? For people who do get the virus, will it be severe and will it beat Delta to become the coronavirus champion of the world?So on today's Coronacast, what we know from the

Just like we're likely going to be stuck with COVID for the rest of our lives, we're probably also going to be stuck wondering which is the most effective vaccine to protect against it.Well lucky we've got science to help sort it out, with a new study putting the Moderna and Pfizer vaccines head-to-head across hundreds of thousands of people.And other scientists have been busy working out how much protection you have against reinfection, if you are infected in the first place.Also on today's show:*

Can Omicron evade our vaccines?

2021/12/01

As the days tick by since Omicron was discovered, it's slowly spreading around the world.One example is reports of a couple of Israeli doctors who likely picked up Omicron in the United Kingdom, before flying back home.Their symptoms are said to be mild at the moment, but more worryingly, both of the doctors were fully vaccinated with Pfizer - that's all three doses.So what do we know about how Omicron works with our current vaccines?

Do we really know yet if Omicron is "milder"?

2021/11/30

Nearly two years into the global coronavirus pandemic, it's probably safe to say that we're all pretty much ready for it to be done.So no wonder we're hoping that very early reports from South Africa are possibly, just maybe, indicating that the Omicron variant is "milder" than variants before.But how much evidence is there for that yet? Is it true, or just wishful thinking?Also on today's show:* Is it possible that the emergence of this variant is actually an encouraging development for the COVID

2021/11/29

As the world desperately awaits news from scientists on anything Omicron, some experts have started thinking about where the variant might have come from.One theory is that it's from someone severely immunocompromised, where the virus has had millions of opportunities to evolve against a poor immune response.But it's far from the only theory.So on today's Coronacast, a few other possibilities of where - and when - Omicron might have popped into existence.Also on today's show:* The evolutionary

Hello Omicron. Goodbye Delta?

It's the news we didn't want: There's a new variant of concern in town and it's got all sorts of mutations just where you don't want them.It's also got a new fancy name: Omicron, and it's reportedly outpacing Delta in countries in southern Africa.But is it really? Is it more infectious? Is it more virulent? Is it vaccine resistant, and if so by how much? How much do we really know at the moment?

How does COVID rank against other pandemics?

As pandemics go, the coronavirus one is pretty big. It rapidly spread around the world, and is still causing problems.But how does it compare to past pandemics? Are we actually living in a fortunate time in human history?If we could magically replace COVID with a bug from the past, would it be a good or bad idea? Would you prefer the plague? Syphilis? Perhaps a flu pandemic might tickle your fancy.Well to help you decide, on today's Coronacast, we go through the pandemics in history.Also on today's

All around the country at the moment are family discussions and debates about what to do about that one relative or friend who still doesn't want to get vaccinated.The numbers of double vaccinated people continue to rise as people realise it's in their benefit to get the jab.But there will always be holdouts, no matter what policies are put in place.So how much does it matter if someone at the Christmas party is unvaccinated when nearly 90 percent of us 12 or older are double dosed?Also on today's

When the slew of variants popped into existence last year, scientists began worrying what it could mean for vaccine resistant variants down the line.So far, the Delta variant has remained top dog. While it is much more infectious than the original coronavirus, thankfully it doesn't evade our vaccines by much.But what about down the line? As more and more of the world is vaccinated, will the virus find a way to evolve to get around vaccines? That’s on today’s Coronacast.Also on today’s show:*
