Gathering together lots of data, and summarising it one chart, an overview of why the boosters matter:
Basic message, if you aren't vaccinated, get vaccinated. If you were vaccinated more than 6 months ago, and you're in an eligible risk group get a booster. But, of course, that's just about cases and most of us are more interested in serious illness, hospitalisations and deaths.
A reminder of what covid is doing through the age groups.
In terms of raw numbers, the majority of deaths are in the oldest, but we're still seeing an unnecessary large number of deaths in the 30/40 something's, where a lot of people remain unvaxxed. The changes over the past year (comparing the yellow and the blue lines) are almost entirely related to vaccine uptake and the groups about to get boosters are likely to start falling further soon.
