McKinsey report shows Delta has moved the goal posts for governments and business globally

The Delta variant has moved the goalposts.

By Katy McLaughlin, Senior McKinsey editor, Southern California.

Some parts of the world felt a surge of optimism in the spring, as vaccination rates were climbing and COVID-19 cases dropping. Those regions now face the disappointment of a reversal, thanks to the spread of the Delta variant.

Such whiplash is starting to feel like a way of life for people everywhere, as well as for industries including shipping, retail, and healthcare.

This week, McKinsey published updated research examining when the pandemic might end and attempted to estimate when some pandemic-related disruptions could return to what we used to call normal. 

Among high-income countries, cases caused by the Delta variant reversed the transition toward normalcy first in the United Kingdom, during June and July of 2021, and subsequently in the United States and elsewhere.

McKinsey’s analysis supports the view of others that the Delta variant has effectively moved overall herd immunity out of reach in most countries for the time being (exhibit). The United Kingdom’s experience nevertheless suggests that once a country has weathered a wave of Delta-driven cases, it may be able to resume the transition toward normalcy. 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. The biggest overall risk would likely then be the emergence of a significant new variant.

McKinsey’s data outlined above in figure form appears to show Australia will need to get much higher vaccine coverage than the Doherty Institute’s findings, the latter of which form the basis of Australian National Cabinet’s opening up plan.

  1. Do we have a councillor who has the mind to ask of the general manager of Coffs Harbour City Council a simple question? She or he can put it in their own words. Such as this:

    “What proof can you provide that the Cultural and Civic Space (sic) building if built will remain open, as you have stated to the public, and not be closed by NSW State Government Health Orders?”
