Getting COVID booster alongside flu shot could reduce hospitalisations, study finds
In a study published in the Medical Journal of Australia, Burnet Institute researchers found that offering COVID-19 vaccination boosters alongside the flu shot could reduce the hospital admission rate for COVID-19 by up to 14 per cent.
It comes amid a renewed push by experts for Australians to get the COVID-19 booster as the NB. 1.8.1 variant has driven up infections.
Researchers used mathematical models to compare scenarios where COVID-19 vaccines were delivered at different times of the year.
The results showed that even though COVID-19 was not seasonal like influenza, increasing COVID-19 booster rates by offering them at the same time as the influenza vaccine was still likely to be an effective public health strategy.
In the last six months, there have been 1.3 million doses of COVID boosters administered to people aged 18 years and over.
Experts have been proactive in their push for higher vaccination rates.
Among them is Burnet Institute head of modelling and biostatistics, and co-author of the study, Associate professor Nick Scott.
He said offering both vaccinations at the same time could also be a simple way to increase vaccination coverage.
"By offering a COVID-19 booster vaccination alongside the annual influenza vaccination, we could aim to achieve similar vaccination coverage for COVID-19 as influenza, which would make a meaningful difference in reducing hospital admissions and deaths," he said.
Another of the study's co-authors, mathematical modeller Fenella McAndrew, said the research showed that getting vaccinated at any time against COVID-19 was a benefit, so it made sense to receive both vaccinations together.
"Unlike influenza, COVID-19 doesn't have a well-defined season, and when we modelled different scenarios, the percentage of people receiving booster vaccinations was more important than the timing of the vaccination," she said.
With such a reliable vaccine available for COVID-19, it makes sense for people to receive regular booster vaccinations to protect themselves, she added.
COVID-19 infection can lead to serious illness that can impact every system in the body, leading to a variety of health concerns including cognitive decline, immune system damage, liver impairment, kidney disease and reduced lung function.
It can also increase the risk of cardiovascular disease and diabetes.
The Australian government recommends COVID-19 booster vaccinations every 12 months for healthy adults between the ages of 18-64 without any risk factors.
Older Australians, aged 75 and older, without any risk factors are advised to receive a booster vaccination every six months.
According to the Department of Health, regular COVID-19 vaccinations are the best way to maintain your protection against severe illness, hospitalisation and death from COVID-19.
They are especially important for anyone aged 65 years or older and people at higher risk of severe COVID-19.

New $90 million research facility opens at CSIRO to house specimens collected over 150 years
Millions of irreplaceable biodiversity specimens have been re-homed at a new CSIRO facility that the agency says will support research to better understand and manage Australia's natural environment. Named 'Diversity', the $90 million National Research Collections building in Canberra features temperature-controlled vaults that are bushfire and pest-resistant while designed to preserve 13 million specimens for future generations. Among the specimens, which have been collected over 150 years, are 55,000 birds, 17,000 orchids, 2.4 million moths and seven million beetles. Dr Clare Holleley, who is the director of vertebrate collections, says the facility serves as a "time machine for Australia's biodiversity". "It's taken snapshots of specimens over time, and when we put all of those little snapshots together, it puts together a picture of how Australia's biodiversity is changing. "We can learn from those trends and potentially predict what is going to happen in the future." The collections include 99 per cent of Australia's native birds, as well as exotic bird species, skeletons, mammals, reptiles stored in ethanol, eggs and frozen tissue. Relocating the specimens took about a year. The official opening of the facility coincides with National Science Week, described by CSIRO chief executive Doug Hilton as an "exciting" moment. Dr Hilton described the facility as "cutting-edge", featuring new genomics laboratories and digitisation facilities that will allow scientists to extract and share more information from research specimens. "If we can't understand how things are changing over time, it's very hard to conserve things for the future," he said. "What we have here is a facility that holds specimens in a highly secure way and allows us to digitise and automate digitisation in a way that is just the envy of the world." While there was celebration at the opening of the building, concern remains about the potential of job cuts at the agency, with the Community and Public Sector Union warning that hundreds of jobs could be axed this year. In responding to those concerns, Dr Hilton said: "Our science has to adapt". "There are programs of research that we may have to stop in order for us to be able to do new programs of research to tackle those big problems like productivity, sustainability and our sovereign science capacity." He said the agency would be reviewing its whole portfolio of science next month and then would need to make "hard choices", but wouldn't say how many jobs could be affected. The new National Research Collections building was jointly funded by the CSIRO and the Department of Education through the National Collaborative Research Infrastructure Strategy. While the building won't be open to the public, the collections will be accessible to researchers, governments, and citizen scientists worldwide.

NSW Health probe finds 'no definitive evidence' of health impacts from Cadia gold mine
An investigation has found no definitive evidence of health impacts from exposure to heavy metals in emissions from one of the largest gold mines in Australia. New South Wales Health has released the findings of an 18-month investigation into dust exposure from Cadia Valley Operations (CVO) near Orange in the state's central west. It was triggered by concerns among neighbouring farmers who worried heavy metals from the mine were contaminating their properties and posing health risks. CVO's owner, Newmont Mining, pleaded guilty to breaching air pollution regulations between 2021 and 2023 and was fined in the Land and Environment Court earlier this year. The Environment Protection Authority, which initiated the legal proceedings, adjusted the mine's environmental protection licence in late 2024, which saw changes to its requirements for monitoring air, surface water and groundwater. Eight adults and six children from seven properties were selected to take part in the NSW Health investigation, and the volunteers were identified through the local group Cadia Community and Sustainability Network. NSW Health acknowledged that the results did not represent "a population-level epidemiological assessment" but provided insights based on the sample. "A NSW Health investigation into the potential health risks of dust exposure from the Cadia gold mine … has found low community exposure to heavy metals, and no definitive evidence of health impacts from heavy metal exposure among volunteers who were assessed," NSW Health said in a statement. Samples were collected from indoor dust, water, soil and homegrown produce, and clinical assessments were also conducted on the 14 participants. A small group of people returned "slightly elevated concentrations of arsenic and mercury in their blood", but NSW Health concluded the levels were not considered to pose any health risks, and were likely a result of dietary intake rather than environmental exposure. However, NSW Health suggested follow-up testing for those participants. "In one case, repeat and alternative testing through an existing specialist was suggested to further explore a health concern." One of the key concerns initially raised by the community was that people may be ingesting heavy metals through dust that was contaminating their rainwater tank supplies. NSW Health's investigation found copper and zinc were detected in most samples, while lead, manganese, arsenic, chromium, cobalt and nickel were found in some of the samples collected, and close to the reporting limit. But it said the levels were at or below drinking water guidelines and consistent with other metal concentrations found in other sampling events in the area. NSW Health established the Cadia Mine Expert Advisory Panel, which reviewed the investigation's results. The panel concluded no evidence of significant contamination at volunteers' properties was found, and there was no indication that broader community testing was required at this time. The ABC has contacted Cadia Community and Sustainability Network and Newmont Mining for a response.

Whose economic summit is it anyway?
Productivity is the word of the week, dominating the lead-up to Treasurer Jim Chalmers' Economic Reform Roundtable. Even the RBA's rate cut - which had the Treasurer metaphorically dancing in the aisles - was quickly overshadowed by a warning from the RBA Governor: Australia's productivity is falling faster than forecast. It's shaping up as a summit with big stakes - and behind the scenes, there's been a quiet tug of war over who owns it. Is this Anthony Albanese's policy agenda, or Jim Chalmers' political stage? All of that comes off the back of an historic announcement from the Prime Minister to begin the week - Australia will formally recognise Palestinian statehood, triggering diplomatic ripples at home and abroad. Patricia Karvelas and Fran Kelly are joined by Melissa Clarke, Radio National Breakfast political correspondent on The Party Room. Got a burning question? Got a burning political query?
