The proportion of the population with effective immunity for both COVID-19 vaccines and prior infection is separated from the aforementioned proportions of the population with effective immunity from COVID-19 vaccines only and from the population with effective immunity from prior COVID-19 infection only. 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. Art exhibitions, ball pits for kids, free mini co-working spaces avoid empty storefronts at all costs and make the main street into a local destination. The emergence of Omicron during the winter of 202122 is visible as a sharp drop in immunity in multiple countries (since existing immunity was suddenly less effective against the new variant). Estimated case-detection rates range from 3:1 to 10:1.2Charlie Giattino, How epidemiological models of COVID-19 help us estimate the true number of infections, Our World in Data, August 24, 2020, ourworldindata.org; Hazhir Rahmandad, John Sterman, and Tse Yang Lim, Estimating COVID-19 under-reporting across 86 nations: Implications for projections and control, medRxiv, August 3, 2020, medrxiv.org. The dynamics of seasonality may cause differences between the northern and southern hemispheres. While the vaccines used in Western countries remain highly effective at preventing severe disease due to COVID-19, recent data from Israel, the United Kingdom, and the United States have raised new questions about the ability of these vaccines to prevent infection from the Delta variant.84 Arjun Puranik et al., Comparison of two highly-effective mRNA vaccines for COVID-19 during periods of Alpha and Delta variant prevalence, medRxiv, August 8, 2021, medrxiv.org; Alistair Smout, English study finds 50-60% reduced risk of COVID for double-vaccinated, Reuters, August 3, 2021, reuters.com; Berkeley Lovelace Jr., Israel says Pfizer Covid vaccine is just 39% effective as delta spreads, but still prevents severe illness, CNBC, July 23, 2021, cnbc.com.

The first two factors combine to drive the number of cases, while the third determines the number of severe cases and deaths. We also introduce the McKinsey COVID-19 Immunity Indexa tool for understanding a communitys current level of risk from the disease. NSW 'could' have 25,000 COVID-19 cases per day. Emerging data on these antibodies suggest that they can reduce the need for hospitalization of high-risk patients, and hold potential for post-exposure prophylaxis.154Laura DeFranceso, COVID-19 antibodies on trial, Nature, October 2020, nature.com; Coronavirus (COVID-19) update, FDA, November 2020. Unless these countries choose to maintain their border restrictions (such as hotel-based quarantine) indefinitely, they might accept the risk of endemic COVID-19 after governments determine that a sufficient portion of the population is vaccinated.102 Salma Khalik, Moving from Covid-19 pandemic to endemic: Singapores strategy and how it can unfold, Straits Times, July 3, 2021, straitstimes.com; Peter Collignon, Australia must eventually face reality: Live with Covid or become a hermit nation, Guardian, June 15, 2021, theguardian.com. A new dominant variant will receive a Greek-letter name, but until then we have created more descriptive names for our scenarios. Total deaths are the estimated number of deaths attributable to COVID-19, including unreported deaths. 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. While an initial course of all WHO-approved vaccines continues to provide strong protection against severe illness and death, the rate of breakthrough cases increases meaningfully as time passes, indicating that protection declines with time. Many countries are hoping that a vaccine will do the bulk of the work needed to achieve herd immunity. 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. 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. 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.

The positive readouts from the vaccine trials mean that the United States will most likely reach an epidemiological end to the pandemic (herd immunity) in Q3 or Q4 2021. One consequence is that the vaccines contribution to population-wide herd immunity will depend on adults, at least until vaccines are approved for use in younger populations. the efficacy rate may not prove high enough to drive herd immunity. But Omicron-specific boosters (especially to address BA.4 and BA.5) could potentially emerge this autumn and significantly enhance the efficacy of vaccines against the predominant strain.9Peter Marks, Coronavirus (COVID-19) update: FDA recommends inclusion of Omicron BA.4/5 component for COVID-19 vaccine booster doses, US Food and Drug Administration, June 30, 2022.

Protection against any infection (including asymptomatic disease) is likely to be lowerand protection against severe disease is likely to be higher. This article presents a new analysis of a range of scenarios based on the infectiousness, immune evasion, and severity of disease caused by the Omicron variant. Read More 31 December 2020 46 Comments Blog. It's one thing to know that the way we see COVID is changing, that this is potentially a milder variant for most people and mass vaccinations should prevent the huge rate of hospitalisation and death seen overseas last year.
