Conclusions
These results suggest that restrictions applied for a long period or reintroduced late in the pandemic (for example, in the event of a resurgence of cases) would exert, at best, a weaker, attenuated effect on the circulation of the virus and the number of casualties. Combined with the results in Haug et al. (2020), they suggest that lockdowns should be strict and brief.
...
Even if restrictions played a role early on, they had a one-off effect that would be hard to replicate going forward. This suggests that the heavy reliance on lockdowns as in the early stages of the pandemic may not be advised.
