For months now, experts have been saying we'll need three doses to be protected from coronavirus, especially the Omicron variant. And now, it's official. Yesterday, the rules changed and people over 16 will be required to have all three doses of a COVID vaccine to be considered "up to date". So why make the change now when previously two vaccines were considered good enough? And might it mean for vaccine mandates down the track?

Two years into the pandemic, we're still discovering new things about COVID almost daily. The latest is what COVID can do to your heart, a year after you've been infected. A huge study has shown really disturbing problems from heart attacks, to strokes, to blood clots on the lungs to heart failure. So on today's Coronacast, who is at most risk? And what does this tell us about COVID as a disease? Also on today's show: * International tourists - what will they bring? * The real story about aged c...

When it comes to ways to fight COVID-19, vaccines have been the main tool we've used so far during the pandemic. But new antivirals are being produced for use including in Australia which has recently provisionally approved two different drugs. They promise to help stop at-risk people ending up in hospital and dying. So what are the drugs, how do they work and will they usher in a new way of handling the pandemic?

As the Omicron wave continues to subside, there's the temptation to hope that now that it's over, the whole pandemic is done. And while we can dream that it's true, hoping unfortunately won't help that become reality. The general weariness is understandable for us everyday people, but what about for policy makers and their preparations for new variants or the next wave? Also on today's show: * Are we really at Omicron's peak? * Can a person be infected simultaneously with two or more strains of ...

Looking at the family tree of coronavirus is a bit like taking a trip down memory lane. The whole crew is there including the famous ones like Alpha, Beta and Delta, and the ones that never really made it into the big time. But what if we zoom in on Omicron? Lately, there's been a bit of noise made about a few Omicron sub variants. What are they? And how much should we worry? Also on today's show: * TGA releases a post-market review for rapid antigen tests. What can we learn from it? References:...

As the scary peaks in all states and territories in Australia, except WA, seems to be behind us, there is now a new sense of calm. Daily coronavirus cases seem to be falling for now, and there's renewed hope that the worst of this wave is behind us. And according to some experts, it could well be the case both here and globally. Due to so many people now either infected by Omicron or vaccinated, they say we may be settling into a new trough of equilibrium. So is it the end of the pandemic? Or ju...

The number of people dying from COVID hit a record high this week, as large case numbers continue in most states and territories. It comes as no surprise then that NSW and Victoria announced that people can get their third dose at the three month mark, bringing it forward from the 31st January which was originally planned. So why roll out boosters even earlier? Could the number of deaths be tied to people not being as protected as they could be? Also on this week's show: * Vaccine supply and log...

We're all no doubt very tired of the pandemic by now and could be forgiven for hoping now that Omicron has landed in Australia, once we get over the current outbreak it's all over. But according to evolutionary virologist Eddie Holmes, sadly Omicron won't be the last and in fact the next variant probably won't evolve from Omicron. So what can we do apart from get vaccinated and hope this terrible roller coaster ride will somehow end soon?

Well, that escalated quickly. When Coronacast left you last year, there were nearly 4000 national daily cases. Yesterday, there were more than 72,000 and there's no sign it's slowing down. Health systems in most states and territories are beginning to groan under significant pressure. Add to it probably more than one or two hundred thousand cases a day going unreported, it's fair to say COVID in Australia is in a bit of a mess. So on today's Coronacast - which will be coming out weekly for at le...

It's been a massive year for coronavirus and COVID-19. There have been outbreaks, lockdowns and a pile of new variants. But there have also been massive successes like the vast majority of Australians coming forward to be vaccinated. But sadly, the pandemic seems like it's far from over. So on today's last Coronacast of the year, we look forward to 2022 and offer some tips on how to stay safe this summer. We'll be back around February 2022! Thanks so much for listening and writing this year....

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 ha...

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 i...

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...

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? Als...

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 n...

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 researc...

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 deci...
