Delta variant: What we know about the science, Centers for Disease Control and Prevention, August 6, 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,, Christie Aschwanden, Five reasons why COVID herd immunity is probably impossible,. While it is known to be highly prevalent in the United Kingdom and present in the United States, there is a significant chance that it will predominate throughout the United States over the coming months. The most important of these are being vaccinated and wearing masks in high-risk environments.. Our estimates of three to eight months for manufacturing, distribution, and adoption of sufficient vaccine doses to achieve herd immunity remain unchanged, and suggest that the milestone may be reached between July and December 2021. 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. 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. Transitions will be gradual. https://lnkd.in/gQczZ6Um Could the same happen in the U.S.?,. In 10 years, COVID-19 will be circulating seasonally alongside the four other major coronaviruses that cause mild to moderate illnesses, such as the common cold.

The United States, Canada, and much of the European Union are now in the throes of a Delta-driven wave of cases.95 COVID data tracker weekly review, accessed August 15, 2021; COVID-19 daily epidemiology update, August 18, 2021; SARS-COV-2 Delta variant now dominant in much of the European Region and efforts must be reinforced to prevent transmission, warn WHO/Europe and ECDC, European Centre for Disease Control and Prevention, July 23, 2021, ecdc.europa.eu; Ceylan Yeginsu, The new reality of a European trip: Things are going to change, New York Times, July 30, 2021, nytimes.com. With queues for kilometres at some PCR test sites that actually opened over the Christmas weekend and rapid antigen tests rarer than the hottest Christmas toy, frustrations ran deep. We think Q3 or Q4 of 2021 are even more likely to see herd immunity in the United States. Without continued immunization, population immunity to current variants, including Omicron, will lessen over time. The threshold to achieve it is governed by a number of factors, including the transmissibility of the disease.138Eames, Fine, and Heymann, Herd immunity: A rough guide, pp. We believe that herd immunity in the United States is still most likely in third or fourth quarter 2021, but that the chance of delay until first quarter 2022 or beyond has increased (Exhibit 2). Debates have continued about the role of vaccine mandates, the use of vaccine passports, testing requirements, masks and mask mandates, and restrictions on gatherings. 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. Variant prevalence is taken from Outbreak.info, which summarizes the data uploaded to GISAID. Subscribe for free to get the latest breaking news and analysis sent to your inbox. The curve rises sharply from Q1 2021 to a peak between Q3 and Q4 2021. 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. Web2022 Nostradamus seven 2022 predictions: From the death of Kim Jong-un to war in Europe and the collapse of the EU From the death of a dictator to cataclysmic quakes, Nostradamus is believed to have predicted dire events for 2022. Omicron is a game changer, Prime Minister Scott Morrison said on Thursday. For example, the COVID-19 death rate per capita in the past month for the United States is 50 percent higher than Argentinas and ten times greater than the Philippines.44Mortality risk of COVID-19, Our World in Data, ourworldindata.org. 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. We believe that those are all reasonable expectations, based on public statements from vaccine manufacturers and the results of surveys on consumer sentiment about vaccines.174Joe Myers, 3 in 4 adults around the world say they would get a COVID-19 vaccine, World Economic Forum, September 1, 2020, weforum.org. 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. Many models predict thresholds of about 40 to 50 percent. 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). Anna Engberg, COVID-19: Vaccine mandate enforced in Austria, Healthcare IT News, February 1, 2022, healthcareitnews.com.

While the variant of concern appears to be most widespread in the United Kingdom, it has been detected in over 30 countries, many of which (including the United States) have limited capacity for genetic sequencing. 4According to CDC ACIP interim recommendations (December 22, 2020), will vary as individual states are making their own decisions (CDC phase 1a = healthcare personnel, long-term care facility residents; CDC phase 1b = frontline essential workers, persons aged 75 years; CDC phase 1c = persons aged 6574 years; persons aged 1664 years with high-risk medical conditions; essential workers not recommended for vaccination in phase 1b); phase 2 estimate based on 2019 census population estimate of persons aged 16, less population accounted for in CDC estimates of persons covered in phases 1ac; CDC and Operation Warp Speed vaccination guidelines may evolve over time. In practice, we have data on whether people who are vaccinated are less likely to get sick with COVID-19 (and less likely to get severe disease), but we wont have data on how likely they are to transmit to others. Clinics have been set up around Australia dedicated to supporting patients suffering from the condition, but funding for many of them is not certain. Today, much of the world is intensely focused on it, but we can reasonably expect the imminent threat to abate. Consumer surveys suggest that a portion of the population is cautious about vaccination. They have already begun in some locations and could be well advanced in most countries by the first or second quarter of 2021. : TransmissibilityDelta is significantly more transmissible than either the ancestral COVID-19 variant or other variants. 22. On the other hand, ECDC also notes that it is too early to draw definitive conclusions on disease severity. More-infectious viruses require that a higher percentage of people be simultaneously immune to reach herd immunity.136Ken Eames, Paul Fine, and David L. Heymann, Herd immunity: A rough guide, Clinical Infectious Diseases, 2011, Volume 52, Number 7, pp. Dr Griffin said it demonstrated that continuing to try to suppress the virus indefinitely "isn't really feasible, with these new sub-variants, in particular". The death of the wallet. Choose a holistic set of health, economic, and social markets that they are managing for, Monitor and track progress against them in ways that allow for targeted response escalation when needed, Limit disease through effective use of vaccines, therapeutics, and other countermeasures, Slow transmission through testing and environmental/workplace modifications, the potential for new variants to emerge (for example, a variant that evades vaccine-mediated immunity to the extent that it frequently causes severe disease in the vaccinated and spreads widely would likely have the most significant effect on any countrys prospects for reaching the end of the pandemic), further evidence of waning natural and vaccine-mediated immunity over time, and challenges with rolling out vaccine boosters quickly enough to maintain immunity, further challenges with vaccine manufacturing or global rollout, changes in the ways that countries define an acceptable burden of disease (for example, setting different targets for disease burden in vaccinated and unvaccinated populations), Population vaccinatedthe proportion of people who have received the vaccine so far, Vaccine courses securedthe additional supplies for which a country has contracted, Consumer vaccine sentimentthe publics willingness to be vaccinated, Population under 19 years of agea greater proportion of children makes a transition toward normalcy easier to achieve but herd immunity more difficult, Natural immunity, or the rate of prior COVID-19 infectionhigher. The second end point of the pandemic may be reached earlier than the first. Coronavirus pandemic (COVID-19), Our World in Data, accessed July 24, 2022.

Some health authorities have indicated most long-COVID patients will be best cared for by GPs and allied health professionals in the community. Finally, an economic threshold for endemic COVID-19 will come when epidemiology substantially decouples from economic activity and secondary economic effects largely resolve. It's tempting to see the testing crisis as evidence of Australia falling at the first hurdle, but in reality, the hurdles are gone andthe track has changed. Lee Landenberger, Novavaxs COVID-19 vaccine shows 100% protection against severe disease, March 12, 2021, bioworld.com. Exhibit 3 lays out three example scenarios for the potential characteristics and trajectory of the pandemic under a new dominant variant. Europe splits on Omicron response, New York Times, December 20, 2021.28Michael Ollove, Amid Omicron Uncertainty, States Resist New Mandates, PEW, December 10, 2021, pewtrusts.org. Millennials continue on to family-sized houses. Twelve months ago, most people werent thinking about COVID-19. Several clinicians in South Africa have noted the apparently mild presentation of Omicron cases.61Fareed Abdullah, Tshwane district Omicron variant patient profile - early features, South African Medical Research Council, December 8, 2021. Recent developments suggest that herd immunity is less likely to come in early 2021, given that vaccines are arriving roughly on the expected timeline; and the downside scenario stretching into 2022 is also less likely, since efficacy is clearer. As Australia transitions its COVID-19 strategy, it has rapidly gained immunity over the past year through a combination of vaccination and infections. His prediction, shared by other experts, is based on cases in Australia this past summer (its winter). The situation may be dynamic as vaccines are approved at different times, each with its own considerations in manufacturing and distribution. 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. While even greater infectiousness (such as the sub-variant BA.2 has exhibited) is possible, to become dominant a new variant would likely need to also partially or fully evade prior immunity, including that provided by Omicron infection. I would expect there to be a higher hospitalisation rate because the lungs, you know, once it gets into lungs its a more severe disease.. Every press conference, every QR code, every public health poster. Hybrid work will dominate. The formula relies on several broad assumptions. 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. Customer segmentation will be trickier in 2022. SARS-CoV-2 and Surface (Fomite) Transmission for Indoor Community Environments. She said her doctor was flippant when she asked about it. While these uncertainties are important, they do not necessarily change the story of a transition toward endemicity under Omicron. The Delta variant increases the short-term burden of disease, causing more cases, hospitalizations, and deaths.82 Delta variant: What we know about the science, Centers for Disease Control and Prevention, August 6, 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. If thats true, then while they are further along, they may also have further to go. Since I like a challenge, I looked at demographic, social, and economic data to come up with 22 predictions of what 2022 will hold in store for Australia. However, slow initial rollout of the vaccines and the spread of more infectious variants increase the risk that significant mortality continues in the second quarter, blunting a transition to normalcy. Existing vaccines may protect against the Brazilian coronavirus variant, University of Oxford, March 18, 2021, ox.ac.uk. Yet its also oddly anticlimactic: the text arrives then nothing. This base-case scenario has the potential to place a severe strain on healthcare systems. At-risk countries. Immunity each day is considered with respect to the dominant variant in circulation in the population in each country. They estimate that the proportion of infected people was at least twice as high as indicated by cases reported to authorities by the end of February 2022. Surging cases put immense pressure on the nation's health systems, with rising COVID-19 cases in hospitals and valuable healthcare workers being sent into isolation as they became infected. While initial data suggest that COVID-19 vaccines do block significant transmission,129Smriti Mallapaty, Can COVID vaccines stop transmission? Here we review five implications; each has helped refine our probability estimates for the COVID-19 pandemic timeline. As populations get closer to this state, it may be helpful to introduce some nuance to what we mean by the term. 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.

Both the pace of case growth and the rapidly increasing share of Omicron among samples sequenced suggest that, through a combination of greater infectiousness and immune evasion, Omicron is spreading very quickly.60Sarah Zhang, Omicrons explosive growth is a warning sign, Atlantic, December 8, 2021. Eames, Fine, and Heymann, Herd immunity: A rough guide, pp. The next wave of medical advances will also prompt questions. Past estimates and COVID-related resources will But in regions with strong public-health responses, normalcy can likely come significantly before the epidemiological end of the pandemic. Previous editions of this article invoked a comparison of the COVID-19 burden to that from other diseases such as flu. Merck expects COVID-19 pill molnupiravir to be effective against Omicron, Reuters, January 11, 2022, reuters.com. "In order for us to go from the pandemic phase to an endemic phase, the virus has to be widespread.". Omicron is a sobering reminder that SARS-CoV-2 has the advantage of rapid mutation and can produce new variants faster than anyone would like. If T-cell cross-reactivity provides meaningful immunity, it would offer significant progress toward herd immunity. For this reason, the continued global rollout of COVID-19 vaccines remains an investment in our collective safety as well as an imperative to protect individuals. The booster campaigns of the six countries shown in Exhibit 3 have primarily utilized mRNA vaccines. Based on a reproduction number (R0) of 2.4 for the original strain and assuming that the herd immunity threshold can be approximated using the formula 1- (1/R0). This article was edited by Josh Rosenfield, an executive editor in the New York office. The possible time frame for them to manage COVID-19 as an endemic disease is less clear. Ideally, we will tighten building codes in Queensland to prepare for a major monsoon event that will occur sooner or later (or so my sources in the BoM tell me), purchase better firefighting equipment (again, I am being told we need more firefighting airplanes), and put systems in place to provide quick financial support for the victims of extreme weather events. Source: Bloomberg; DC; HHS; Moderna; Pfizer; Reuters; WSJ. "No one wants to see [large numbers of COVID-19 deaths] happenbut, from a population point of view, we're in an OK place at the moment," Dr Lydeamore said. Peter Loftus, Moderna is testing its COVID-19 vaccine on young children,. This might make COVID-19 analogous to measlesa disease that causes intermittent, limited outbreaks in countries with well-developed vaccination programs but significant ongoing disease in parts of the world where access to vaccines is more limited. How many COVID cases go unreported each day? Vaccines are also likely to be made available to children in the coming months,90 Samantha Artiga, Jennifer Kates, Kendal Orgera, and Jennifer Tolbert, The next stage of COVID-19 vaccine roll-out in United States: Children under 12, Kaiser Family Foundation, July 30, 2021, kff.org. Treasury is estimating a historical surge in net migration, but several factors including changes to COVID policy settings make the prediction seem far-fetched. Science brief, last updated March 8, 2021; Matthew Smith, Europe is becoming more pro-vaccine, YouGov, January 22, 2021, yougov.co.uk. It is gained through vaccination (primary series and boosters), infection with SARS-CoV-2, or both (hybrid immunity). It first caused major waves of disease in India and the United Kingdom and more recently triggered serious outbreaks in many other countries. Sarah Zhang, Omicrons explosive growth is a warning sign,. 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. We acknowledge Aboriginal and Torres Strait Islander peoples as the First Australians and Traditional Custodians of the lands where we live, learn, and work. We just have to wait and see though that those few days of data turn into the trend that we hope that it is., Sign up to receive an email with the top stories from Guardian Australia every morning.

Very well stated. Most countries have made significant progress in reducing the numbers of deaths and hospitalizations associated with COVID-19. Global attitudes: COVID-19 vaccines, Ipsos, February 9, 2021, ipsos.com; Yasmeen Serhan, The vaccine-hesitant man of Europe,. "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.". Victoria which had been sputtering along mainly in the low 1,000s since the end of lockdown started picking up around then too, albeit at a lower rate than NSW. WebA fantastic post on the top 10 issues of 2022. The winter of 202223 may see a more substantial uptick in the Northern Hemisphere, but this is unlikely to be as severe as the December 2021February 2022 The nation has seen thousands of COVID-19 deaths since then, dwarfing the tolls from 2020 and 2021. 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%). Public-health authorities around the world are considering short- and medium-term strategies for the timing and rollout of booster shots. And the rules changed again less than 24 hours later. 23Emma K. Accorsi, Amadea Britton, Katherine E. Fleming-Dutra, et al, Association Between 3 Doses of mRNA COVID-19 Vaccine and Symptomatic Infection Caused by the SARS-CoV-2 Omicron and Delta Variants, January 21, 2022, jamanetwork.com.. Countries where a significant portion of those at risk had received three doses of vaccine, including at least one dose of mRNA vaccine, saw hospitalizations substantially decouple from cases.24New COVID-19 cases worldwide, Johns Hopkins University & Medicine, February 20, 2022, coronavirus.jhu.edu. Booster vaccinations will be important in maintaining immunity levels over time.100 US to advise boosters, August 16, 2021. 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. The PALM scheme has since expanded to include hospitality, age care and tourism jobs. "I think that the practicality and the feasibility outweighs any potential benefit of implementing those sort of measures," Dr Griffin said. 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. The biggest overall risk would likely then be the emergence of a significant new variant. The pace at which governments relax public-health measures will be critical. Nor is it clear yet what the approval standards might be for multi-valent vaccines. Although advances in detecting and treating COVID-19 lead the news less frequently than they did a year ago, important developments continue to emerge. If vaccines are only 75 percent effective at reducing transmission, then coverage of about 60 to 80 percent of the population will be needed for herd immunity. Time traveller reveals wild predictions for 2022, including new Covid strain A so-called time-traveller has made a series of incredible claims about the year ahead, 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. What scientists know so far,. One is that each member of a population mixes randomly with all other population members. "If this sort of trend continues, then that's good news for us, in that it's just becoming moretransmissible, it's not becoming any more severe," he said. Lets face it Microsofts introduction of the ChatGPT (generative AI) enabled Bing search engine as well as the ChatGPT embedded co-pilot in all Microsoft Office The emergence of Omicron led to tighter rules around travel in many countries, with some, such as England, also restricting domestic travel.76Prime Minister confirms move to plan B in England, United Kingdom, December 8, 2021. 3. Here, as in other regions, the timing of access to vaccines will be the biggest driver of the end of the pandemic. There is no evidence of higher case fatality with either new strain, but there are fears that new strains may affect how antibodies bind to the virus and may reduce the efficacy of vaccines or antibody treatments developed over the past few months. Research and findings of the past two months have shed light on a number of uncertainties and in some cases have raised new questions. 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. These approaches could reduce mortality in the short term by broadening access, but they could also delay herd immunity if, for example, a delayed second dose reduces efficacy. And government policy still mattersin particular, the few remaining countries with zero-COVID-19 strategies may also experience the coming months differently as they choose whether to continue or relax their border policies. Baby Boomers will act with a sense of urgency. Delta-cron (Omicrons twin) and Milder-cron scenarios we described in our March 2022 update remain a reasonable summary of the range of possibilities for the impact of future variants. Vaccination remains an essential element in building immunity. Raising vaccination rates will be essential to achieving a transition toward normalcy. Alistair Smout, UK PM Johnson speeds up plan to end COVID self-isolation rule, Reuters, February 9, 2022, reuters.com. Public-health authorities may therefore need to look at a wider range of indicators to support their planning and disease management efforts. "If you don't fulfil this definition of a close contact then there is no need for you to be in that line," Mr Morrison said. For an example of a low-end estimate, see Max Fisher, R0, the messy metric that may soon shape our lives, explained,, Frank Ball, Tom Britton, and Pieter Trapman, A mathematical model reveals the influence of population heterogeneity on herd immunity to SARS-CoV-2,. This data will be published in 2022 and will show that Australians had even fewer kids during COVID there will be no coronavirus baby boom. WebEven for the Upgraded Scenario we might expect 14% of time is expected in some form of lockdown, with a wide uncertainty range of 0% to 50% of the year in lockdown. Those results have generally been achieved through a combination of moderately effective interventions rather than a single big bang (Exhibit 3). Dr Lydeamore said he was concerned that, as we entered a new year, vaccine coverage across the nation was "dropping rapidly". On the other hand, if vaccine uptake is fast, New Zealand might achieve a longer-lasting vaccine-based herd immunity. Data are not yet available on the drugs efficacy in vaccinated individuals. If new strains predominate, they could lead to a longer timeline to herd immunity.
