Jenny Cordina, Eric Levin, and George Stein, COVID-19 Consumer Healthcare Insights: What 2021 may hold, June 24, 2021, McKinsey.com. An earlier timeline to reach herd immunityfor example, Q1/Q2 of 2021is now less likely, as is a later timeline (2022). We might then expect to see a seasonality-driven wave of disease next fall and winter, but hospitalizations would likely peak well below the level of the wave we just experienced. As growth in the regions continues, local councils must make enough land available to accommodate the increased demand for housing. This distinction will have much to say about whether the United States reaches normalcy in Q2 or Q3 of 2021. What are the implications of the ChatGPT4 / Generative AI They are keen to travel, spend time with the grandkids, and feel its their time now.

Johnson, The war has changed: Internal CDC document urges new messaging, warns delta infections likely more severe,. On the other hand, ECDC also notes that it is too early to draw definitive conclusions on disease severity. Such therapies are also easier to administer in lower-resourced regions than injected or infused treatments are. 10. Exhibit 4 provides a global view of seven factors that are likely to drive herd-immunity timelines for the rest of the world. The year of the endemic phase? 7 predictions for 2022 Allowing for the risk of another new variant and the compound societal risk of a high burden of influenza, respiratory syncytial virus, and other winter respiratory diseases, the question for these countries will be whether they manage to arrive at a different epidemiological endpoint, as we discuss next. COVID-19 Again, when a new "national" set of rules for close contacts and testing were announced on Thursday with four different timelines, and exceptions in South Australia, an "in principle" yes but no changes in WA and an announcement to come from the NT. A McKinsey Live event on COVID-19 vaccines are here. As ever, different parts of the world will experience the coming phase differently. As immunity wanes, however, the next stage remains highly uncertain. That trend is likely to continue whilst the special COVID rulesfor working holidaymakers introduced by the Coalition Government remain in place and the labour market remains strong. Other advanced economies are probably on similar timetables.

Depending on vaccination progress over the summer (whether the United States is on the earlier or later end of the herd immunity window), there may be a smaller fall wave of disease in third to fourth quarter 2021. The past month or two have seen seven important developments: Whats the net impact of all these developments? 20. The drugs are more likely to be effective if taken within five days of symptom onset,68Merck and Ridgeback Biotherapeutics provide update, November 26, 2021; Pfizers novel COVID-19 oral antiviral treatment candidate, November 5, 2021. requiring an efficient pathway from diagnosis to prescription and distribution. Fifth, and most concerning, variants that reduce the efficacy of vaccines or the benefits of natural immunity may spread widely. is blind to contagious new virus variant, scientists warn, New York Times, January 6, 2021, nytimes.com. In April 2020, we were told 30,000 Queenslanders would die, that demand for intensive care could peak at 35,000 beds a day, that Victoria could have reached 58,000 cases a day. WebThe Consumer Price Index (CPI) rose 1.9% this quarter. These are my 22 predictions for 2022. So, as we consider future waves, two critical questions remain about the duration of protection: how significantly will immunity wane? In this article, well review the developments since our last perspective (January 21), offer an outlook for each of the three geographies, assess risks, and outline what the end of the pandemic might look like. 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.

Only two measures will be looked at: deaths per million and the vaccination rate. The world doesnt care about internal political squabbles in Australia or whether a lockdown was too strict. Herd immunity might not be reached until 2022 or beyond. Having suffered a wave of cases caused by the Delta variant during June and the first few weeks of July, the country delayed plans to ease many public-health restrictions and eventually did so on July 19, though expansive testing and genomic surveillance remain in place. One is that each member of a population mixes randomly with all other population members. National cabinet encourages wearing masks to combat COVID-19. 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. Singapores government has announced that it will make this shift, and more countries may follow its lead.96 Niharika Mandhana, From pandemic to endemic, Singapore creates model for living with Covid-19, Wall Street Journal, July 1, 2021, wsj.com. 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). (Note: these scenarios are not related to the Omicron-hospitalization scenario shown in Exhibit 2.). Early 2022 will see the return of migration, albeit not yet at pre-pandemic levels. Its possible that unforeseen developments such as significantly more infections than expected this winter could lead to earlier herd immunity. 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. 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). Some (not all) of these changes will stick. But for now, fewer of us need to get testedand, according to Morrison, that's cause to relax. We have written previouslyabout the transition to managing COVID-19 as an endemic disease and noted that a new variant was one of the greatest risks to timelines.

If you look at it now, its more like 40 deaths a day. Its probably several times that number of cases.. Most countries have deferred the hope of achieving herd immunity until the arrival of a vaccine. F. Javier Ibarrondo et al., Rapid decay of anti-SARS-CoV-2 antibodies in persons with mild COVID-19,, Rebecca Cox and Karl Brokstad, Not just antibodies: B cells and T cells mediate immunity to COVID-19,, Katie Thomas, New Pfizer results: Coronavirus vaccine is safe and 95% effective,. As cases decline, our analysis suggests that the United States, Canada, and the European Union could restart the transition toward normalcy as early as the fourth quarter of 2021, provided that the vaccines used in these countries continue to be effective at preventing severe cases of COVID-19. Some have suggested that particular populations, such as those who are immunocompromised due to HIV or other causes, are disproportionately at risk of incubating new variants.41Lawrence Corey, Chris Beyrer, Myron S. Cohen, Nelson L. Michael, Trevor Bedford, and Morgane Rolland, SARS-CoV-2 Variants in Patients with Immunosuppression, The New England Journal of Medicine, August 5, 2021, nejm.org. 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.

Three levers are likely to be especially important, starting with the extent to which countries can effectively scale and make available new oral therapeutics with the potential to reduce the chance of progression to severe disease, and which are unlikely to be blunted by Omicron. Tt c bi vit tagged "product_bot-arrowroot-huu-co-h-to Yes, its no longer an absolute acute emergency like it was, because we have a large percentage of our population vaccinated and weve got better treatments. but public-health responses to Omicron have typically been less forceful than those of prior waves with similar disease burdens. 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). 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. As populations get closer to this state, it may be helpful to introduce some nuance to what we mean by the term. Transitions will be gradual. 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. Evidence of past infection was also the highest among young blood donors (27 per cent), matching higher reported case numbers in this age group.
