Explainer: The Delta variant of COVID-19 is growing exponentially in England, even outside the original hotspots, new data has revealed
The sharp rise in the figures could be partly due to increased surge testing and sequencing in these areas, as well as the spread of the variant itself. Until now, it was not thought exponential growth on this scale was happening in as many parts of England.
Now, a paper referenced by the PHE report suggests it is 64% more transmissible within the home, even after adjusting for age, sex, ethnicity, socioeconomic background and vaccination status. But, the good news is that people who have been double vaccinated have similar levels of protection against the Delta variant as they do against the Alpha variant.
A single vaccine dose also offers less protection against the Delta variant. It is as much as 17% less effective than it is for Alpha in the case of some vaccines.
