THIS week’s UKHSA vaccine surveillance report has landed – and this week there’s a change. In the (in)famous Table 12, which shows rates of infections, deaths and hospitalisations per 100,000 by vaccination status, the data have suddenly switched to giving rates for triple-jabbed rather than two-or-more doses, meaning we no longer have continuity with our previous data. So sudden was the change that the report itself has not kept up with it, and the notes under the table still say the rates are for ‘people who have received either two doses of a Covid-19 vaccine or in people who have not received a Covid-19 vaccine’.
The change means we have to re-start our week-by-week comparisons, so the infection rates by age for this period are depicted above and the unadjusted vaccine effectiveness figures below.
Below is how the total reported infections for the period break down by vaccination status (in this chart vaccinated means one or more doses). While the chart doesn’t take into account the different numbers of people vaccinated and unvaccinated, with over 70 per cent of infections in the vaccinated it does show that the outbreak is predominantly in vaccinated people.
