From the WashPost: Shutdowns prevented 60 million coronavirus infections in the U.S., study finds.
Shutdown orders prevented about 60 million novel coronavirus infections in the United States and 285 million in China, according to a research study published Monday that examined how stay-at-home orders and other restrictions limited the spread of the contagion.
A separate study from epidemiologists at Imperial College London estimated the shutdowns saved about 3.1 million lives in 11 European countries, including 500,000 in the United Kingdom, and dropped infection rates by an average of 82 percent, sufficient to drive the contagion well below epidemic levels.

Unfortunately, the headline is somewhat misleading. As noted in body, some things worked and some didn’t. The most devastating action in terms of the economy – the lockdowns – apparently had no discernible impacts. Further, the baseline is not clear in the second study – 500k lives saved in the UK – compared to what? The IC’s discredited model?
