Covid: how has the pandemic changed in the UK in 2021?

Last year, Covid-19 cases were soaring in the UK, hospitalisations were increasing, and the government had tightened restrictions to try to get a handle on a new variant.

There is a sense of familiarity. A weary public is worried about its festive plans being canceled, an outcome that would be all the more painful in light of the Christmas party scandal that has engulfed Downing Street in recent weeks.

The government is pinning its hopes on a booster campaign to hold back aidal wave of Omicron.

The link between Covid infections and death has been weakened by the UK's vaccination campaign.

The decision to declare freedom day in mid-July feels less like a mission-complete moment than it does.

The Guardian plots the UK's vaccine progress against government decisions and the number of Covid deaths in 2021.

The one thing we can say for certain is that a line has not yet been drawn under the Covid pandemic.

There are data notes and methodology.

The UK daily deaths are based on the government's primary metric from the Covid-19 data dashboard which only includes deaths that occur within 28 days of a positive Covid test. The latest death count as recorded by the Office for National Statistics was 173,525 occurences, which includes all deaths where Covid was mentioned on the death certificate deaths to 10 December.

The government has a data dashboard called Covid-19. The percentage is the proportion of adults who have received two doses of the vaccine.

The University of Oxford has a government response tracker. Anything below a stringency index score of 75 is considered to be very low.
