Its possible that regular revaccinations would be required to maintain immunity, and ongoing surveillance for COVID-19 will be required. Given the likely timing of herd immunity in various geographies and the uncertain duration of protection from vaccines (both duration of immune response and efficacy versus new variants), it is likely that some measures such as booster vaccines are likely to be required indefinitely. Instead, it is most likely as of now that countries will reach an alternative epidemiological endpoint, where COVID-19 becomes endemic and societies decidemuch as they have with respect to influenza and other diseasesthat the ongoing burden of disease is low enough that COVID-19 can be managed as a constant threat rather than an exceptional one requiring society-defining interventions. Almost two years into a pandemic that has claimed more than five million lives and affected billions more, people everywhere are finding it hard to summon the energy for another chapter in the story.51Charlie Giattino et al., Excess mortality during the coronavirus pandemic (COVID-19), Our World in Data, December 7, 2021. A transition to the next normal, in whatever form that takes, will come gradually when people have confidence that they can do what they used to do without endangering themselves or others. 9116.

Further, the European Centre for Disease Prevention and Control (ECDC) noted on December 12, 2021, that 776 cases were within its remit and all cases for which there is available information on severity were either asymptomatic or mild. If you look at it now, its more like 40 deaths a day. 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. First, up-to-date vaccination status, including a recent booster, proved to be especially important in protecting against Omicron21Effectiveness of a Third Dose of mRNA Vaccines Against COVID-19Associated Emergency Department and Urgent Care Encounters and Hospitalizations Among Adults During Periods of Delta and Omicron Variant Predominance VISION Network, 10 States, August 2021January 2022, Centers for Disease Control and Prevention, January 28, 2022, cdc.gov.

Catch up on the latestCOVID-19 news here. The United Kingdom appears to be making this shift now (though cases there were increasing as of this writing). FatalityLimited evidence suggests that the case fatality ratio (the proportion of deaths among confirmed cases) of the Delta variant is roughly one and a half to two times greater than that of ancestral COVID-19. Exhibit 2 lays out the likely timing of vaccine availability in the European Union. In just 10 months, the cost of servicing an average $600,000 mortgage will have risen by more than $14,000 per year once those rate hikes are fully passed through. In the context of Omicrons arrival and impending spread, three factors come to the forefront: the potential impact of new therapeutics in reducing hospitalizations and death, the criticality of boosters in the context of waning immunity, and clarity and consensus in public-health measures. A second (and likely, earlier) end point, a transition to normalcy, will occur when almost all aspects of social and economic life can resume without fear of ongoing mortality (when a mortality rate is no longer higher than a countrys historical average) or long-term health consequences related to COVID-19. Even before the emergence of Omicron, the past four months have seen the continued evolution of the public response to COVID-19. The transition would gradually normalize aspects of social and economic life, with some public-health measures remaining in effect as people gradually resume prepandemic activities. If they fail to do so, regional house prices will continue to rise sharply. Researchers are learning more about differences among individuals attitudes, which include both cautious and unlikely to be vaccinated. 91 COVID-19 Consumer Healthcare Insights, June 2021. The initial evidence indicates that the efficacy of these therapies is unlikely to be reduced by the mutations present in the Omicron variant.67Jason Gale and John Lauerman, How does Omicron challenge the treatments for Covid?, Bloomberg, December 9, 2021.

The Pfizer trial has enrolled some children (ages 12 and older), but efficacy in those under 18 remains unclear. The world doesnt care about internal political squabbles in Australia or whether a lockdown was too strict. David Heymann, the chairman of the World Health Organizations Strategic and Technical Advisory Group for Infectious Hazards, noted in December that endemicity may be the destiny of this virus.146Melissa Davey, WHO warns Covid-19 pandemic is not necessarily the big one, Guardian, December 29, 2020, theguardian.com.

Based on a range of likely vaccine scenarios and the fact that those with prior exposure to SARS-CoV-2 will still be eligible for vaccination, every ten percentage-point increase in seroprevalence could roughly translate into a one-month acceleration of the timeline to the epidemiological endpoint. The changes to the close contact rules should limit the number of healthcare workers taken off the roster and strengthen the system, along with a new directive from NSW to allow asymptomatic staff deemed as close contacts to leave self-isolation. One of the reasons is that weve seen a very poor uptake of the third dose, the booster dose we know that two doses wont protect you against infection, he said. As described in Ensheng Dong, Hongru Du, and Lauren Gardner, An interactive web-based dashboard to track COVID-19 in real time,. The decline in the efficacy of COVID-19 vaccines over time and the benefits of booster doses have become much better understood over the past three months.

Experts say it's important the community understands that isn't the case but there are some things that could make the next year a little easier than the past three. WebCHNH SCH GIM GI HAMPER 2022 Thng 12 20, 2022 Tags. As part of Australia's COVID-19 plan for 2023, PCR testing will be prioritised for the most vulnerable, in a bid to ensure their access to antivirals is fast-tracked. In the United States, supply is well ahead of demand.11John Farley, FDA updates on Paxlovid for health care providers, US Food and Drug Administration, May 4, 2022. More retail spending will take place online. A previous post predicted the economy, politics, and drug pricing reform in Get The New Daily free every morning and evening. But here lies the cognitive gap for Australians. At this stage, when monthly mortality from COVID-19 may start to resemble that of flu in an average year, we may see a transition toward normalcy, albeit with public-health measures still in place. While the European Union, the United Kingdom, and the United States have had broadly similar COVID-19 experiences, other parts of the world look very different. These five factors combined mean that there is still a meaningful chance that herd immunity is not reached in the medium term. In this extract from Pandemedia, The Australian Financial Reviews Patrick Durkin explains how his coronavirus experience began with a car race. In the United States, COVID-19 hospitalization and mortality rates in June and July were nearing the ten-year average rates for influenza but have since risen. Patrick Knox and Laura Gesualdi-Gilmore The Sun 3 min read December 30, 2021 - 9:00AM Some initial data offer concerning evidence that B.1.351 and P.1 may be examples of such variants, although recent Novavax data (with a small sample size) offer some reassurance that its vaccine is effective against severe disease caused by B1.351.130Lee Landenberger, Novavaxs COVID-19 vaccine shows 100% protection against severe disease, March 12, 2021, bioworld.com. 1/15/21 estimate. We dont yet know how long the protection the vaccines offer will last. Cases moved from double digits on December 21 to well into the 3,000s by year's end. The question of disease severity is more complicated. Copyright 2023 The New Daily. While the situation looks somewhat better in parts of the Southern Hemisphere, much of Europe and North America is in the midst of a fall wave, with the prospect of a difficult winter ahead. On November 26, 2021, WHO reached deeper into the Greek alphabet to declare Omicron a new SARS-CoV-2 variant of concern.50Update on Omicron, WHO, November 28, 2021. For example, with a variant that is 40 to 80 percent more transmissible, vaccine efficacy of 90 percent would require 83 to 100 percent of those over 12 to be vaccinated; efficacy of anything less than 75 percent would make herd immunity likely unachievable through vaccination of only those over 12. In the base case (25 percent more infectious; 25 percent greater immune evasion; 25 percent less severe disease), the COVID-19-related hospitalization rate in the United States could peak significantly higher in the next six months than in the past six. 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. 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. But a number of other factors could delay the timelines beyond those described, including unexpected safety issues emerging with early vaccines, significant manufacturing or supply-chain delays, continued slow adoption, further mutation, or a shorter-than-anticipated duration of vaccine-conferred immunity. "So, I still think we should have ready access to testing so we can find cases and link high-risk people with antivirals more readily than perhaps we are at the moment.". By and large, the six-month outlook in many countries is brighter than at any time in the past two years. Such therapies are also easier to administer in lower-resourced regions than injected or infused treatments are. This general point appears to be especially true for the Omicron variant.71Pfizer and BioNTech provide update, December 8, 2021. A psychic who claims she saw the Covid-19 pandemic coming in 2018 is now warning of everything from political upheaval to a world war in the years ahead. But several uncertainties could temper the optimism, starting with the duration of immunity. Things will be fine by January 2022. Even countries, such as the United States, with high McKinsey COVID-19 Immunity Index scores continue to experience many new COVID-19 cases as a result of the extremely high transmissibility of current SARS-CoV-2 variants. Much work remains to be done. Yet the past two weeks have brought renewed hope, headlined by final data from the Pfizer/BioNTech150Pfizer and BioNTech conclude Phase 3 study of COVID-19 vaccine candidate, meeting all primary efficacy endpoints, Pfizer, November 18, 2020, pfizer.com. "Not only is the spread of this virus inevitable, it is necessary," he said on Thursday. As Australia transitions its COVID-19 strategy, it has rapidly gained immunity over the past year through a combination of vaccination and infections. Natural immunity to SARS-CoV-2 Gen X is taking over even more leadership positions. Nicholas Casey and Norimitsu Onishi, Crack down hard, or wait and see? This means downsizing is pushed backwards too. When we give people immunity, we change the risk calculus; this was the main reason for vaccinating the community. Those results have generally been achieved through a combination of moderately effective interventions rather than a single big bang (Exhibit 3). "I've gotsevere mortgage stress and a $100 doctor's bill was a really significant cost for me," she said. Factors that could influence actual outcomes include: The surge of COVID-19 cases resulting from the spread of the Delta variant and from vaccine hesitancy brought a sudden, tragic end to the transition toward normalcy that some countries had begun to make. COVID infections soared in January thanks to the original Omicron variant, with states around the country reporting a combined 150,702 new cases on January 13. Earlier in the pandemic, it was unclear how long immunity after COVID-19 infection would last. Lots has been written about this. And third, given public fatigue and the lessons of the past two years, finding the right combination of public-health measures will be critical. Michael Lydeamore an infectious diseases modeller from Monash University said while there had been more COVID-19 deaths than anyone in the community would want in 2022, excess mortality estimates from the Australian Bureau of Statistics were starting to come down again. Professor Esterman said there is also hope that Australias youngest will soon be able to get vaccinated against COVID-19, with children under five now eligible to receive their first dose in the US. Some countries in this group, such as Australia, have recently faced a Delta-driven surge in cases, but in absolute terms the burden of disease remains low relative to other countries. WebCHNH SCH GIM GI HAMPER 2022 Thng 12 20, 2022 Tags. For an example of a high-end estimate, see Seth Flaxman et al., Estimating the effects of non-pharmaceutical interventions on COVID-19 in Europe, Nature, August 13, 2020, Volume 584, pp. 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 all wish that level could be zero, eliminating the disease is not feasible for any country with open borders. Immunity can only partly predict the burden of disease at any point in time. 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,. It is still early days, and there is time to accelerate, but there is little margin for error if the United States is to achieve herd immunity in third quarter 2021. We have previously written about herd immunity as a likely epidemiological endpoint for some countries, but the Delta variant has put this out of reach in the short term. Even later herd immunity remains possible if other challenges arise, especially vaccine safety concerns or ambivalence to vaccination following a transition toward normalcy. Despite his grim outlook on COVID-19 deaths, Professor Esterman said its not all doom and gloom. John Farley, FDA updates on Paxlovid for health care providers, US Food and Drug Administration, May 4, 2022. A McKinsey Live event on COVID-19 vaccines are here. More data are likely to emerge on this in the weeks ahead. Early 2022 will see the return of migration, albeit not yet at pre-pandemic levels. Herd immunity is not the same as eradication. The Stats Guy: 22 predictions of what 2022 holds for Australia. In the United States and most other developed economies, the epidemiological end point is most likely to be achieved in the third or fourth quarter of 2021, with the potential to transition to normalcy sooner, possibly in the first or second quarter of 2021. The concerning development in recent weeks has been the confirmation of new strains in South Africa, the United Kingdom, and elsewhere that combine multiple mutations and have different profiles. And this will have an impact on hospitalisations because of the sheer numbers, he said. In such places, until herd immunity is reached, COVID-19 might be analogous to measlesnot a day-to-day threat to most people, but a persistent risk. A number of questions and caveats remain. That's an approach that will continue in 2023, with a national COVID-19 plan outlining an approach based on an informed community taking the lead on protection, alongside vaccine supply certainty and a focus on taking the pressure off hospitals. We've heard the horror stories testing centre queues so long they were closed just minutes after opening time, friends who'd visited upwards of five sites trying to get a pre-holiday test, people with long-standing medical appointments missing out on a required PCR test. 20. This article updates our perspectives on when the coronavirus pandemic will end to reflect the latest information on vaccine rollout, variants of concern, and disease progression. However, the future uptake of boosters is a significant unknown. For example, I suspect that the demand for working from home will be stronger in Melbourne than elsewhere. The researchers estimate that at least 17 per cent of Australian adults had been infected with SARS-CoV-2, the virus that causes COVID-19, by the end of February We will see case numbers go up, which are effectively production numbers going up. Fareed Abdullah, Tshwane district Omicron variant patient profile - early features, South African Medical Research Council, December 8, 2021. Epidemiological update: Omicron variant of concern (VOC) data as of 12 December 2021 (12.00), ECDC, December 12, 2021. Of course, we're not alone the whole world is being buffeted. It showed gamers were losing more than $23m every day and statewide losses in pubs and clubs totalled $4.26bn in late 2022, generating $1.18bn in tax. The timing of such a transition will depend on the progress toward herd immunity, as previously detailed (since more people with immunity means fewer deaths and long-term health consequences), and on the effectiveness of a countrys public-health response. Evidence so far suggests that the Omicron variant, relative to Delta, is likely to be more infectious, show more immune evasion, and be less severe, on average. What's new this quarter The worst-case scenarios were avoided. Recent projections suggest that it is likely to take until late 2022 or early 2023 for these countries to achieve high vaccine coverage.104 Sara Jerving, Africa not on track for 10% COVID-19 vaccination rate by end of year, Devex, July 30, 2021, devex.com; Over half a billion COVID-19 vaccine doses administered in WHO South-East Asia Region as countries scale up vaccination efforts, World Health Organization, August 6, 2021, who.int.

Berg et al., Mandated Bacillus Calmette-Gurin (BCG) vaccination predicts flattened curves for the spread of COVID-19,. 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. In less than three months, Omicron has spread around the world, caused record peaks in cases in many places,16WHO Coronavirus (COVID-19) Dashboard, World Health Organization, February 2022, covid19.who.int.

Francesco Guarascio, Moderna eyes COVID booster by August, not clear yet if Omicron-specific needed, Reuters, February 17, 2022, reuters.com. Evidence of past infection was also the highest among young blood donors (27 per cent), matching higher reported case numbers in this age group. Our scenario analysis suggests that Omicron-related hospitalizations are likely to continue to decline in the United States and remain at relatively low levels through the spring and summer (Exhibit 2).

In this extract from Pandemedia, The Australian Financial Reviews Patrick Durkin explains how his coronavirus experience began with a car race. Receiving a text revealing you have tested positive to COVID is a big moment, filled with uncertainty about what is to come. "You should go home. The strain is likely to continue spreading in the coming months, propelled by its reproductive advantage over the original. The nation has seen But the same shortfalls in access that bedevil the distribution of vaccines in low-income countries are striking again with therapeutics: doses sit unused in high-income countries while other parts of the world lack access.12Ann Danaiya Usher, The global COVID-19 treatment divide, National Institutes of Healths National Library of Medicine, February 24, 2022. Dr Lydeamore said the fact that multiple branches of evolution of the virus were ending up in a similar position was a sign of "convergent evolution", and could be a good thing. Since the Omicron variant of COVID-19 was named by WHO on November 26, 2021, it has moved at lightning speed. For example, Eli Lillys antibody bamlanivimab was granted Emergency Use Authorization (EUA) by the US Food and Drug Administration on November 9,153Coronavirus (COVID-19) update: FDA authorizes monoclonal antibody for treatment of COVID-19, US Food and Drug Administration, November 9, 2020, fda.gov. Without continued immunization, population immunity to current variants, including Omicron, will lessen over time. While there has been at least a few documented cases of reinfection, most experts expect that the majority of those exposed to the virus are immune for some period of time. The trend towards sliding into retirement continues. Immunity protects individuals and reduces risk for people in the community around them by reducing rates of onward transmission. Its not clear when use in children will be indicated. The process will be enabled by tools such as vaccination of the highest-risk populations; rapid, accurate testing; improved therapeutics; and continued strengthening of public-health responses. Globally, of the approximately 30 million people known to have COVID-19, more than 900,000 have died.1Coronavirus Resource Center, Johns Hopkins University & Medicine, September 18, 2020, coronavirus.jhu.edu. While the United States could still achieve herd immunity in the third or fourth quarter of 2021 (in line with the peak probability in our previous estimates), the emergence of more-infectious variants of SARS-CoV-2 increases the risk that this milestone will not be achieved until later.
