During our second lockdown the increase in cases did slow down a bit, but only a bit. One could argue, that the soft lockdown didn't really work that well, as it didn't turn the ship around.
The interesting part of the statistics was, that the age bracket of 20 - 35 was the only one with reduced infection numbers during the 2nd (soft) lockdown. So all positive effects from this age group were totally negated by every other age bracket - be it school children (massively increased numbers due to open schools), of kinder garden kids (same with open). Or also older people seemingly (no idea of the reasons) contracting Sars-CoV-2 at an increased rate during the soft lockdown.
I have no idea for why these other age brackets have increased numbers. Could be that these are also the age brackets were you find the most critics, but that is just a totally unproven hypothesis of mine.
Could be that behavior changed in regards to the first lockdown and people do not keep their social distancing as much as they did (that is just anecdotal evidence from encountering people not keeping their distance while grocery shopping).
