The UK Zoe Covid-19 study has changed its methodology for counting new Covid-19 cases and vaccine breakthroughs, possibly following the reaction to this article last week which showed vaccine breakthroughs in the UK at nearly 50%.

The new Zoe methodology shows that vaccine breakthroughs are now at 40% of new Covid-19 cases – see the chart at the top of this post. The chart also shows that there are now more Covid-19 cases in the fully vaccinated than in the partially vaccinated.

Meanwhile, the Zoe study have said that they will stop counting new unvaccinated Covid-19 cases soon as “the numbers of unvaccinated people of all age groups are so low“.

“As you see in the graph below, when we overlay our previous estimate (red line) and new adjusted estimate (orange line) in a single graph, we can see our updated methods align more closely to trends observed in government confirmed cases (blue line)”
