Seroprevalence data indicates around 79.1% of the population have antibodies to SARS-CoV-2 from either infection or vaccination, compared to 14.8% from infection alone.

The hospital admission rate for COVID-19 has risen – it was 1.48 per 100,000 in week 23, compared to 1.13 per 100,000 in the previous week.

Hospital admission rates for COVID-19 are highest in the North West, with a rate of 2.62.

Dr Yvonne Doyle, Medical Director of Public Health England, said:

Case rates have increased across all age groups and regions around England, and we are seeing further increases in hospitalisations. We now know that 2 doses of either vaccine offer very high levels of protection against hospitalisation from all variants, including Delta, so it is important to take up the offer of the vaccine to protect yourself and others.

We know that many of you will be currently enjoying Euro 2020, but please when going to fan zones or celebrating with friends, follow the guidelines in place and enjoy the tournament safely.
