Almost 70% of the adult population in England now have COVID antibodies, latest figures suggest.
An estimated seven in 10 adults (68.3%) in private households were likely to have tested positive for coronavirus antibodies in the week to 11 April, according to the Office for National Statistics (ONS).
That's up from an estimated one in two, or 53.1%, two weeks earlier.
The presence of COVID-19 antibodies suggests someone has had the infection or has been vaccinated - and the inoculation rollout has now reached more than 33 million people across the UK.
In Wales, some six in 10 adults (61.0%) in private households tested positive for antibodies in the week to 11 April, according to the same new figures.
This is also up from around one in two adults, or 48.2%, two weeks before.
And for Northern Ireland, the estimate is also six in 10 adults (62.5%) - up from just over one in two (54.6%).
