Depends on where you live, in the Midwest the peak was more around Halloween in October. You can hardly find Thanksgiving in any data (and then you probably have to squint and ignore proper statistics) By Chirstmas/new year things were clearly in decline. Other areas of course have different results.
The vaccines seem to have an impact, but it is hard to be sure. There are a lot less old (>65) in the new infected list, which used to dominate the list. The younger groups seems to be be about even by age group. However there are many potential confounding factors, and I haven't done a proper statistical analysis so I don't want to claim something.
