I've read about that too
Moreover, it had been stated by many right at the very beginning that lockdowns and quarantines were there not to prevent the spread of the virus as it was impossible to do (which proved correct, by the way), but only to slow down the virus so that the healthcare system wouldn't collapse. In other words, governments did everything they could, and now we are already past the point where quarantines could actually be useful. To repeat, they were not to prevent or stop the disease but to slow down its spread and win some time
If that is the case, then I don't think that the objective has been achieved. Mass production of a vaccine is at least 5-6 months away, and we are still witnessing more than 50,000 new cases per day, in each of the major hotspots (Brazil, United States, India.etc). But the fatality rate has gone down, by as much as half. At least in India, the healthcare system is close to collapse.
