It's not the "Oops we were so wrong" that some people want it to be.  A few highlights:

According to the unmitigated scenario, if left unchecked the virus could have infected 7 billion people and caused in the region of 40 million deaths this year. 

The modelling showed that implementing measures early on can have a dramatic impact.  If all countries were to adopt this strategy at 0.2 deaths per 100,000 population per week, 95 per cent of the deaths could be averted, saving 38.7 million lives.

However, if this strategy is adopted later (1.6 deaths per 100,000 population per week), then this figure drops to 30.7 million.

“Our research adds to the growing evidence that the COVID-19 pandemic poses a grave global public health threat. Countries need to act collectively to rapidly respond to this fast-growing epidemic. Sharing both resources and best practice is critically important if the potentially catastrophic impacts of the pandemic are to be prevented at a global level.”
