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. "We perhaps overdid it early on, so the risk perception was too high. Each of the three variables is an important driver of the outcomes. The Stats Guy: 22 predictions of what 2022 has in store for Australia 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. Australia in 2021 Psychic Astrology The fall in COVID-19 cases across much of the world over the past ten weeks signals a new dawn in the fight against the disease. Different levels of lockdown restrictions bred different habits across the country. But it is possible that evolution will not produce epidemiologically significant new variants. Estimates of increased vaccine coverage needed are based on R0 = 3.36-4.32, which is 4080% greater than R0 of 2.4. "Ifyou don't know where you are now, that can make it very hard to know what's coming next. 15. 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. Beyond that, a more realistic epidemiological endpoint might arrive not when herd immunity is achieved but when countries are able to control the burden of COVID-19 enough that it can be managed as an endemic disease. If early vaccine doses reach a significant percentage of high-risk elderly individuals by the end of quarter one, the combination of protecting these groups and the arrival of spring in the northern hemisphere should improve the situation compared with where the United States is now. Please note that this would be subject to change and further delay if the OxfordAstraZeneca vaccine remains suspended in multiple countries following concerns about blood clots; WHO has confirmed its continued support of the vaccine.127WHO statement on AstraZeneca COVID-19 vaccine safety signals, WHO, March 17, 2021, who.int. Other important drivers of disease trends include the variant mix, the season, and behavior (such as masking, compliance with isolation and quarantines, and working from home). Further, higher-than-expected efficacy may help offset coverage challenges that surveys have suggested. And real downside risk remains, especially with respect to duration of immunity and long-term vaccine safety (given the limited data available so far). Nina Le Bert et al., SARS-CoV-2-specific T cell immunity in cases of COVID-19 and SARS, and uninfected controls,, The basic reproductive number (R0) is a measure of contagiousness or transmissibility. Jacqui Wise, Covid-19: Pfizer BioNTech vaccine reduced cases by 94% in Israel, shows peer reviewed study, BMJ, February 25, 2021, Volume 372, Number 8282 bmj.com; Benjamin Mueller, Vaccines sharply cut coronavirus hospitalization, U.K. studies show,. He said improving antivirals which are most effective at reducing severe illness when taken shortly after an infection beginswould also help. As Australia transitions its COVID-19 strategy, it has rapidly gained immunity over the past year through a combination of vaccination and infections. Add to this the rapidly rising positive rate of those who do make it to the front of the line. When will the COVID-19 pandemic end? | McKinsey The United Kingdoms experience nevertheless suggests that once a country has weathered a Delta-driven wave of cases, it may be able to relax public-health measures and resume the transition toward normalcy.87 Sarah Zhang, Watch the U.K. to understand Delta, Atlantic, August 3, 2021, theatlantic.com. These countries, primarily in North America and Western Europe, are the ones discussed above. The long tail of the curve shows falling probabilities to Q3 2023 and beyond. As immunity wanes, however, the next stage remains highly uncertain. Endemic COVID-19 does not mean that the disease poses no risk. We made this point in the last four editions of this article, and unfortunately it remains as true as ever. While countries such as Israel have shown what is possible, the United States has fallen behind its targets.144Coronavirus: Israel leads vaccine race with 12% given jab, BBC, January 3, 2021, bbc.com.145Michelle R. Smith, Governors scramble to speed vaccine effort after slow start, Associated Press, January 6, 2021, apnews.com. While vaccinations have been reducing the risk of severe illness, research is still unfolding into long COVID. Despite his grim outlook on COVID-19 deaths, Professor Esterman said its not all doom and gloom. 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. Esterman said he expected case numbers to drop very slowly or even plateau. Vaccine hesitancy, however, has proven to be a persistent challenge, both to preventing the spread of the Delta variant and to reaching herd immunity.88 COVID-19 Consumer Healthcare Insights, June 2021.

Deltas high transmissibility also makes herd immunity harder to achieve: a larger fraction of a given population must be immune to keep Delta from spreading within that population (see sidebar, Understanding the Delta variant). 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. making it possible to protect a group that comprises a significant share of the population in some countries. and more large employers in the United States implementing vaccine mandates.93 Leslie Josephs and Robert Towey, Covid vaccine mandates sweep across corporate America as delta variant spurs action, CNBC, August 9, 2021, cnbc.com; Alexis Benveniste, From offices to restaurants, companies are requiring proof of vaccination, CNN, August 4, 2021, cnn.com. 9116. They have typically maintained tight border restrictions and a strong public-health response to imported cases. Data released this week saw the fertility rate fell to an all-time low of 1.58 kids per woman in 2020. 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. Will oral therapeutics be available quickly enough to blunt a potential Omicron surge in December 2021 and January 2022? 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. NSW Health Minister Brad Hazzard suggested on December 15 just 18 days ago, when the state recorded 1,360 cases a day that NSW should brace for 25,000 cases a day by the end of January. 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. If vaccines are efficacious, safe, and distributed to all ages, vaccine coverage rates of about 45 to 65 percentin combination with projected levels of natural immunitycould achieve herd immunity (Exhibit 2). Its possible that regular revaccinations would be required to maintain immunity, and ongoing surveillance for COVID-19 will be required. Subpopulations with fewer interactions have lower thresholds for herd immunity than do those with more interactions. A McKinsey Live event on COVID-19 vaccines are here. The next normal wont look exactly like the oldit might be different in surprising ways, with unexpected contours, and getting there will be gradualbut the transition will enable many familiar scenes, such as air travel, bustling shops, humming factories, full restaurants, and gyms operating at capacity, to resume. COVID-19 cases and 7 day rolling 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,. These factors include the following: Herd immunity requires that enough people be simultaneously immune to SARS-CoV-2 to prevent widespread ongoing transmission. Enter a new variant, faster than any we've seen to date, and a lot can change in a matter of weeks. The proportion of the population with effective immunity from COVID-19 vaccines is estimated from historical, reported vaccine administration data (both completed second doses and boosters); rates of vaccine effectiveness against Omicron reported in published literature; rates of waning vaccine immunity reported in published literature; and a generalized assumption that older individuals received COVID-19 vaccines before younger ones did. While regular revaccinations may be needed, perhaps similar to annual flu shots, the threat of widespread transmission will be gone. Melbourne School of Population and Global Health WebCHNH SCH GIM GI HAMPER 2022 Thng 12 20, 2022 Tags. What scientists know so far,. Finally, an economic threshold for endemic COVID-19 will come when epidemiology substantially decouples from economic activity and secondary economic effects largely resolve. In a phase where vaccines are freely available, the government is encouraging lower-risk individuals to instead use rapid antigen testsand stay home if they feel unwell. If new strains predominate, they could lead to a longer timeline to herd immunity. "Not only is the spread of this virus inevitable, it is necessary," he said on Thursday. As COVID-19s impact on health wanes, we are likely to see greater normalization of social and economic life. When Ms Spooner contractedCOVID-19, she said she was unsure of her reporting requirements. Well-executed distribution of effective vaccines will still be paramount. Its probably several times that number of cases.. We're so far beyond COVID-zero that Queensland's Chief Health Officer Dr John Gerrard said it baldly this week: infection with COVID-19 was required for the pandemic to evolve to be endemic a constant presence in our lives. That could happen if a real or perceived safety issue increases hesitancy or if younger populations see little reason to be vaccinated once older cohorts are protected and a transition toward normalcy is well underway. Prior natural infection with a different variant appears to provide only partial protection against Delta. Prospects for the rest of the year and beyond hinge on the questions of whether and when future variants will emerge. In December, Federal Health Minister Mark Butler said the national plan involved funding for research to help better understand long COVID. "But better antivirals, better access to antivirals, will also make a huge difference.". Endemicity remains the endpoint. Most terrifying 2022 predictions - new Covid In its final study, Pfizer reported that PAXLOVID reduced risk of hospitalization or death by about 89 percent for high-risk patients and about 70 percent for standard-risk patients.66Pfizer announces additional Phase 2/3 study results confirming robust efficacy of novel COVID-19 oral antiviral treatment candidate in reducing risk of hospitalization or death, December 14, 2021. Workers still need to come to the office occasionally, and settling too far away from the office towers isnt an option for many. are seeing their worst peak yet, and continuing to tighten restrictions. This article was edited by Josh Rosenfield, an executive editor in the New York office. Until a new variant emerges, and under some scenarios even once it does, the United States and Europe will likely continue to move toward these definitions of endemicity. US mortality for COVID-19 is still higher than the historical average for flu but has fallen by 85 to 90 percent since its early 2021 peak. and is now declining just as quickly. SARS-CoV-2 variants, Centers for Disease Control and Prevention, last updated March 16, 2021, cdc.gov. (modern). The other variables will also have much to say about the timeline to reach herd immunity (see sidebar, Key factors affecting the timeline to herd immunity). Paxlovid and other COVID-19 therapeutics are now widely available in high-income countries. WebOlder Australians Linda is adamant that a lot will change not only with general day-to-day life post-Covid, but also in the world of retirees. WebOver the twelve months to the December 2022 quarter, the CPI rose 7.8%. Many workplaces remain relatively cautious in their policies,30Stephan Kahl, Damian Shepherd, Faris Mokhtar, Claire Che, Nic Querolo, Sarah Holder and Natalie Wong, Omicron Suddenly Upends the Worlds Return to the Office, Bloomberg, December 20, 2021, bloomberg.com. (Exhibit 1). Patrick Durkin BOSS Deputy editor. Since home tests became more widely available, in late 2021, consumer purchases of them have risen in line with waves of COVID-19 cases, prefiguring rises in deaths attributable to the disease (Exhibit 1). It also reduces the fraction of the population required to reach herd immunity. Based on our reading of the current state of the variables and their likely progress in the coming months, we estimate that the most likely time for the United States to achieve herd immunity is the third or fourth quarter of 2021. Australia Data are not yet available on the drugs efficacy in vaccinated individuals. Of these deaths, 4,547 occurred in 2022 more than double the 2,239 deaths recorded over the first two years of the pandemic. A new Covid-19 subvariant is emerging in Australia, with experts warning it might be one of the most transmissible strains so far. Countries like New Zealand have avoided significant COVID-19-associated mortality but appear to be further from herd immunity because so few New Zealanders have infection-driven immunity to SARS-CoV-2. How will drugdrug interactions with ritonavir be managed for PAXLOVID use? Merck expects COVID-19 pill molnupiravir to be effective against Omicron, Reuters, January 11, 2022, reuters.com. In contrast, some locations, such as Hong Kong,17Farah Master and Clare Jim, Hong Kong considers mass testing as COVID fight intensifies, Reuters, February 17, 2022, reuters.com. Moderna also announced that its vaccine is more shelf-stable than expected and would need only refrigeration to keep it stable for 30 daysanother piece of good news. In the short term, public-health measures can help control the pandemic, but even when herd immunity is achieved, managing the risk of COVID-19 will require monitoring, potential revaccination, and treatment of isolated cases. 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. Case controllers. Most countries have deferred the hope of achieving herd immunity until the arrival of a vaccine. As growth in the regions continues, local councils must make enough land available to accommodate the increased demand for housing. If these strains become dominant, they may cause a material delay in reaching herd immunity. 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. One end point will occur when the proportion of society immune to COVID-19 is sufficient to prevent widespread, ongoing transmission. Data so far are mixed on the severity of the disease it causes: some early findings have pointed toward a mild clinical course, while other evidence has suggested that Omicron may lead to more frequent hospitalization in children than other variants do.53Implications of the further emergence and spread of the SARS CoV-2 B.1.1.529 variant of concern (Omicron) for the EU/EEA first update, European Centre for Disease Prevention and Control (ECDC), December 2, 2021; Loni Prinsloo, Toddlers make up 10% of hospital cases in Omicron epicenter, Bloomberg, November 29, 2021. The US has topped 500,000 daily cases andreduced its isolation period, records are being smashed in Europeas many countries increase restrictions,Israel is attempting an uncharted fourth vaccination shot. (For more on the potential for a faster resolution of the COVID-19 crisis in the United States, see An optimistic scenario for the US response to COVID-19.) 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. 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. Both countries target low- to semi-skilled workers, mainly for seasonal agricultural and horticultural work. Data on the availability of vaccine doses in the United States increase confidence that this is possible, but the slow start to the vaccine rollout reinforces that success is by no means guaranteed. Vaccine hesitancy makes it all the more difficult to reach the population-wide vaccination level rates that confer herd immunity. 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. 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. As that happens, countries across Europe are rolling back the last public-health restrictions.45Jamey Keaten, More countries in Europe, recently the pandemics epicenter, ease COVID restrictions, Los Angeles Times, February 2, 2022, latimes.com.
