The rate of Covid-19 infections among people age 55 or over in Britain is increasing, even as it decreases among younger people.

Various causes may be combining to do this. It could be that a substantial fraction of them are now socializing more. It could be that they have been convinced there is no need to take precautions (masks, distance, ventilation, avoiding large groups). It could be that their booster doses are losing effectiveness as the months go by. It could be the new variant BA.2, which is like Omicron by transmits more easily.

This result lumps together all ages 55 and up. I wonder what we would see if the statistics were broken down into 10-year age groups, and into the specially vulnerable and others.
