covid predictions for 2022 australia

Favorable findings on natural and cross-immunity would help accelerate timelines. And some data inconsistencies have emergedfor example, it is unclear why molnupiravirs efficacy in an interim analysis dropped in the final readout.69Merck and Ridgeback Biotherapeutics provide update, November 26, 2021. The second is that rapid antigen tests arent that accurate, he said. The key factor is diminished mortality. Longer-term storage requires freezing at 70 degrees Celsius, requiring special equipment.165Katie Thomas, New Pfizer results: Coronavirus vaccine is safe and 95% effective, New York Times, November 18, 2020, nytimes.com. 2. Eames, Fine, and Heymann, Herd immunity: A rough guide, pp. A communitys level of immunity is a precarious balance, constantly shifting as individuals gain and lose immunity. This means downsizing is pushed backwards too. Some new studies suggest that infection confers more immunity and protection against severe disease than does vaccination alone. The trend towards sliding into retirement continues. SARS-CoV-2 will continue to mutate under all scenarios, but most mutations do not lead to stable new forms of the virus with an evolutionary advantage. At worst, we see a long-tail possibility that the United States could be still battling COVID-19 into 2023 and beyond if a constellation of factors (such as low efficacy of vaccines and a short duration of natural immunity) align against us. AEST = Australian Eastern Standard Time which is 10 hours ahead of GMT (Greenwich Mean Time), abc.net.au/news/covid-omicron-cognitive-leap-into-2022/100734564. Of these deaths, 4,547 occurred in 2022 more than double the 2,239 deaths recorded over the first two years of the pandemic. Paul Griffin an infectious diseases physician and associate professor at the University of Queensland said communicating risk so that Australians could make informed choices remained a challenge. Whats more difficult to estimate is when a new variant of SARS-CoV-2 will emerge. We think Q3 or Q4 of 2021 are even more likely to see herd immunity in the United States. This will help stabilise the inner-city rental market, help fill casual jobs in retail and hospitality, and generally boost the economy. The optimistic scenario would see a peak of disease burden close to that seen over the past six months, while the pessimistic would see a very significantly higher burden of disease than in the past six months. With Omicron as the dominant variant, the pandemic phase will feel like it is over for more and more people, though certainly not all. Society has grown used to tracking the number of COVID-19 infections (the case count). This distinction will have much to say about whether the United States reaches normalcy in Q2 or Q3 of 2021. Treasury is estimating a historical surge in net migration, but several factors including changes to COVID policy settings make the prediction seem far-fetched. While we dont yet know the full extent of waning immunity for Omicron, new evidence indicates that those who have received three doses of vaccine may benefit from medium-term protection.32Frauke Muecksch, Zijun Wang, Alice Cho, et al., Increased potency and breadth of SARS-CoV-2 neutralizing antibodies after a third mRNA dose, BioRxiv, February 15, 2022, biorxiv.org. Director of the Australian National Phenome Centre, Professor Jeremy Nicholson, shares the path forward on how we may continue to live with COVID in 2022 Other epidemiologists have called into question those hopeful estimates and note that policy should be based on conservative estimates of herd-immunity thresholds until better information is available.9Abstractions Blog, The tricky math of herd immunity for COVID-19, blog entry by Kevin Hartnett, June 30, 2020, quantamagazine.org; Apoorva Mandavilli, What if herd immunity is closer than scientists thought?, New York Times, August 17, 2020, nytimes.com. Were still seeing thousands of people being infected; were seeing many, many people ending up in hospital, he said. Its behavior and effects, with respect to several key measurable traits, are as follows1 Delta variant: What we know about the science, Centers for Disease Control and Prevention, updated August 19, 2021, cdc.gov; Yasmeen Abutaleb, Joel Achenbach, and Carolyn Y. Johnson, The war has changed: Internal CDC document urges new messaging, warns delta infections likely more severe, Washington Post, July 29, 2021, washingtonpost.com; Apoorva Mandavilli, CDC internal report calls Delta variant as contagious as chickenpox, New York Times, July 30, 2021, nytimes.com; Michaeleen Doucleff, The Delta variant isnt as contagious as chickenpox. Perhaps the escalation was most marked in Queensland, with its newly reopened border no longer protecting it from the surge. If we are lucky the blow will be softened by an infrastructure boom that creates employment opportunities for middle-income earners. While they are not recommended for use in hospitalized patients, these antibodies add to the growing armamentarium of treatments and protocols for COVID-19, where every incremental advance could help to reduce mortality. We could still get another variant coming along tomorrow, which is worse than Delta., Though the Omicron variant results in less severe disease on an individual level compared with Delta, its high transmissibility had led to vast numbers of infections, Esterman said. But herd immunity would mean that the emergency measures currently in place in many countries could be lifted. These are my 22 predictions for 2022. are seeing their worst peak yet, and continuing to tighten restrictions. Under the Omicrons twin scenario, a variant that evaded prior immunity (including from Omicron) but was otherwise similar to Omicron in transmissibility and severity of disease might cause a wave of disease broadly similar to the one we have recently experienced, though perhaps slightly worse if the public response to it is even more muted and if vaccine-conferred immunity has waned. The recent authorization of COVID-19 vaccines for children as young as six months is also an important step.10Coronavirus (COVID-19) update: FDA authorizes Moderna and Pfizer-BioNTech COVID-19 vaccines for children down to 6 months of age, US Food and Drug Administration, June 17, 2022. 'Felt a bit dodgy': Sydney woman pays $25 for rapid antigen test after chemist sells multipack individually, This man advises his clients that elections, rates and mortgages are invalid, Jock Zonfrillo remembered as an 'incredible chef' and icon of Australia's culinary landscape, Selling the furniture and couch-surfing: Families forced to make 'impossible' decisions amid fears inflation crisis hitting kids, Perfect storm brewing for housing market and it could make buying your own home a pipedream, 'The first three weeks were brutal':Clare went into rehab just as lockdown kicked in 2020, but she stuck with it, A year ago, this Australian couple fled Ukraine with their three cats. Go to the beach, go and do what you want to do. Lee Landenberger, Novavaxs COVID-19 vaccine shows 100% protection against severe disease, March 12, 2021, bioworld.com. The world doesnt care about internal political squabbles in Australia or whether a lockdown was too strict. Several potential definitions of the transition from pandemic to endemic phase are possible (Exhibit 4). The PALM scheme has since expanded to include hospitality, age care and tourism jobs. Potential herd-immunity timelines are bifurcating as a result of growth in variants that may reduce vaccine efficacy. A number of Australian states, territories, and cities have implemented lockdowns in response to the pandemic. When we refer to herd-immunity timelines for a country, we mean the point at which the entire nation or a significant portion reaches herd immunity. BA.5 appears to [be] infecting the lungs, whereas the BA.2 mainly infects the upper airways. Third, the duration of vaccine-mediated immunity may prove shorter than anticipated, making it hard to reach the necessary threshold for simultaneous immunity. So what should you do next? Here's where you can find it, Timely reminder: How to respond if you test positive to COVID-19. University of South Australia professor of biostatistics Adrian Esterman told The New Daily on Monday that COVID-19 deaths were slowly rising as governments wound back public health measures, and would likely average 50 a day by the end of July. Exhibit 1 assumes a US public-health response similar to that seen during the Delta wave. This is a fragile dawn, however, with transmission and deaths still high, unequal access to vaccines, and variants of concern threatening to undo progress to date. "We expect hospitalisations to rise in coming weeks, simply due to the very large number of cases, which will be far larger than the positive tests indicate, due to today's decision.". For example, while 215 million Americans are fully vaccinated, only 93 million have also received a booster dose.33COVID-19 vaccinations in the United States, The Centers for Disease Control and Prevention, February 23, 2022, covid.cdc.gov. We hope that this article offers a starting point to interpret the potential spread and severity of the disease it produces and the ways in which new therapeutics, booster doses of vaccines, and public-health measures will be important in limiting its impact. It isnt yet clear whether public interest in boosters will continue to decline or demand will in time match the historical uptake of flu vaccines (around 50 percent of adults). Exhibit 3 includes three types of immunity for six countries: immunity derived from previous infection only, from vaccination only, and from both (now the largest group in many countries). Data from the US Centers for Disease Control and Prevention also suggest that vaccinated people who become infected with the Delta variant may transmit it efficiently.86 Delta variant, August 6, 2021; The war has changed: Internal CDC document, July 29, 2021; CDC internal report, July 30, 2021; The Delta variant isnt as contagious, August 11, 2021. Although advances in detecting and treating COVID-19 lead the news less frequently than they did a year ago, important developments continue to emerge. "The ones we've used so far have been tremendous in reducing high-risk people progressing to severe disease," Dr Griffin said. The response to Omicron may include both accelerating the rollout of booster doses of existing vaccines and developing new formulations better targeted to this variant. In 2022 we can expect to see tax hikes, energy bill increases and less money in our pockets. Michael Ollove, Amid Omicron Uncertainty, States Resist New Mandates, PEW, December 10, 2021, pewtrusts.org. While the potential for a transition toward normalcy in just a few months is encouraging, many signs suggest that the next six to eight weeks will be difficult. WebA barrier on the state border of Queensland and New South Wales preventing interstate travel in April 2020 during the COVID-19 pandemic in Australia. Caution is still warranted. We hope that our perspectives prove useful to leaders as they set policy and strategy; we will continue to update the series. Research and findings of the past two months have shed light on a number of uncertainties and in some cases have raised new questions. but the real-world impact of their use at scale is not yet known, and supplies of paxlovid are still scaling.38CDC Health Advisory: Using Therapeutics to Prevent and Treat COVID-19, The Centers for Disease Control and Prevention (CDC), December 31, 2021, emergency.cdc.gov; Berkeley Lovelace, Jr., Covid pills are easier to find as the Omicron surge subsides, NBC News, February 23, 2022, nbcnews.org. Just as the risk of flu is considered normal, so too might the risk of COVID-19. We are more confident in this timeline for the United Kingdom than for the United States, given that the first has already experienced a wave driven by a more infectious variant, whereas the latter could still face one. This appears to have occurred in southern England over the past few months. Subpopulations with fewer interactions have lower thresholds for herd immunity than do those with more interactions. The Milder-cron scenario would continue the trend toward less severe disease. For now, we remain bystanders as the virus evolves. This initial version of the McKinsey COVID-19 Immunity Index helps us make a few observations: One significant limitation of the McKinsey COVID-19 Immunity Index is that it doesnt indicate which people within a community are protected. We will We need to get that up to nearly 100%, he said, adding that people over 65 should get their fourth Covid jab as soon as possible. You've got a text to say you're COVID positive. The healthcare sector continues to boom. Some of those measures (such as full lockdowns and restrictions on certain industries) have significant social and economic consequences, and others (such as testing and tracing), while expensive, dont. Subscribe for free to get the latest breaking news and analysis sent to your inbox. We will consider timelines for other countries in forthcoming updates; they will vary based on the timing of access and distribution of vaccines and other factors. More than 85 poor countries will not have widespread access to coronavirus vaccines before 2023, Economist Intelligence Unit, January 27, 2021, eiu.com. Over the past couple of months, the number of tests bought from one online retailer has been rising, which may reinforce the impression that the United States is entering a period of sustained case growth. For an example of a low-end estimate, see Max Fisher, R0, the messy metric that may soon shape our lives, explained, New York Times, April 23, 2020, nytimes.com. Three factors lead us to believe that timelines for herd immunity and transition toward normalcy in the United Kingdom will be similar to those in the United States. Could the same happen in the U.S.?,. The 'winter shot': Everything you need to know about getting your next COVID-19 booster, If you catch COVID again, will your symptoms be worse? The start, peak, and tail of this curve are almost the same as the previous one. Once the threshold is reached, the whole population is protected. doses for 80 percent of the global population, An optimistic scenario for the US response to COVID-19. And its much more powerful than the existing Moderna mRNA vaccine, he said. While a more infectious variant likely means more people are acquiring natural immunity through infection (despite ongoing efforts to minimize new cases), the net impact of more-infectious strains is likely to be that a higher portion of the population needs to be vaccinated, which may take more time. The world will praise Australia for its handling of COVID. The biggest risk to a countrys ability to do this would likely then be the emergence of a new variant that is more transmissible, more liable to cause hospitalizations and deaths, or more capable of infecting people who have been vaccinated. These therapeutics, including both small-molecule and antibody treatments, have helped blunt the incidence of severe disease in places where they are widely available. But he pointed to a number of potential factors. One is a final result, and the other is an initial result whose sample size is large enough to give reasonable confidence in the data. Beyond that, a more realistic epidemiological endpoint might arrive not when herd immunity is achieved but when COVID-19 can be managed as an endemic disease. Another consequence is that older children, who have twice the COVID-19 incidence of younger children and who have higher viral loads (and therefore greater potential contagiousness) than adults158Rebecca Leeb et al., COVID-19 trends among school-aged childrenUnited States, March 1September 19, 2020, Centers for Disease Control and Prevention, October 2, 2020, cdc.gov; Lael Yonker et al., Pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2): Clinical presentation, infectivity, and immune response, Journal of Pediatrics, August 19, 2020 jpeds.com. Since the winter of 2021, this is Omicron for most countries, and we consider immunity against BA.1 and BA.2 rather than the more recent subvariants. A new dominant variant will receive a Greek-letter name, but until then we have created more descriptive names for our scenarios. Add to this the rapidly rising positive rate of those who do make it to the front of the line. The booster campaigns of the six countries shown in Exhibit 3 have primarily utilized mRNA vaccines. 13. Europe and the United States have entered the endemic stage of the COVID-19 outbreak: the virus is widespread, is significantly less fatal than it was in 2020, and is spurring only limited changes in public behavior. The most significant price rises were Domestic holiday travel and accommodation (+13.3%), Electricity (+8.6%), International holiday travel and accommodation (+7.6%) and New dwelling purchase by owner occupiers (+1.7%). Even as some locations reach herd immunity, pockets of endemic COVID-19 disease are likely to remain around the world, for example in areas affected by war or in communities with persistently low adoption of vaccines. Dr Griffin said fatigue with the pandemic was a big part of that, which meant there was a need for balanced commentary to reinforce the measures Australians should still be taking to reduce risk. What happens next? This economic definition is related to the individual behavior definition, but may take longer to reach because those secondary effects, including supply chain imbalances, labor market disruptions, and global asymmetries affecting travel and trade, may linger. Endemic COVID-19 does not mean that the disease poses no risk. It's a big shift from the first few years of the pandemic, where the gold-standard PCR testing was available to everyone in the community in an attempt to identify every case and send rings of contacts into quarantine. Both countries target low- to semi-skilled workers, mainly for seasonal agricultural and horticultural work. Omicron: School closures must be avoided whenever possible, United Nations, December 17, 2021, news.un.org. During the anticipated period, the Australia infection control market in is anticipated to expand significantly. These five factors combined mean that there is still a meaningful chance that herd immunity is not reached in the medium term. We acknowledge Aboriginal and Torres Strait Islander peoples as the First Australians and Traditional Custodians of the lands where we live, learn, and work. Fourth, supply-chain disruptions and delays are real, and could produce supply shocks and interfere with timelines. "Ifyou don't know where you are now, that can make it very hard to know what's coming next. The virus has been mutating since it was identified a year ago. Herd immunity, the second endpoint, is most likely in the third quarter for the United Kingdom and the United States and in the fourth quarter for the European Union, with the difference driven by a more limited vaccine availability in the European Union. This means demand for childcare will remain stable despite declining births. the efficacy rate may not prove high enough to drive herd immunity. All rights reserved. and is now declining just as quickly. (modern). And will booster uptake continue to slow in each subsequent round of boosting? The approval, in at least one country, of vaccines made by Pfizer and BioNTech, Moderna, Oxford and AstraZeneca, Sinopharm, Serum Institute, Bharat Biotech, Gamaleya, and others within a year of viral sequencing smashed all records for development timelines. When this end point is reached, the public-health-emergency interventions deployed in 2020 will no longer be needed. Watch the U.K. to understand Delta, August 2021; Grady McGregor, Sophie Mellor, and Biman Mukherji, Delta waves in India and the U.K. have already receded. They are not intended to be predictive for any individual. Airline passenger volumes in the United States are much closer to prepandemic levels than they were a year ago48TSA checkpoint travel numbers (current year versus prior year(s)/same weekday), Transportation Security Administration, tsa.gov. But as the more infectious Delta variant becomes more prevalent within a population, more people within that population must be vaccinated before herd immunity can be achieved (Exhibit 1). Well-executed distribution of effective vaccines will still be paramount. The relationship between waning antibodies and reinfection risk remains unclear. Historical data are smoothed slightly to reduce small kinks introduced by data-reporting patterns. Hiring qualified staff will be challenging.
