I was trying to look for the source of the image and first came across it being posted in a forum here:

https://www.muftisays.com/forums/96-covid19/13775-covid-vaccine-yes-no-maybe.html?pg=2

I found it in a Twitter post on this account posted on July 14 and it mentions it was by the Expose:

The Expose seems to be a news site with the url: expose-news.com. The article that has this image was written on July 12. The site has annoying popups when you visit it:

https://expose-news.com/2022/07/12/distracted-boris-uk-gov-revealed-vaccinated-highest-covid-death-rate/

The article states that the chart was produced from data provided by ONS (Have no idea what that is:)

From the article, here is the link to the source data:

The latest dataset from the ONS is titled ‘Deaths by Vaccination Status, England, 1 January 2021 to 31 May 2022‘, and it can be accessed on the ONS site here, and downloaded here.

Site: https://www.ons.gov.uk/peoplepopulationandcommunity/birthsdeathsandmarriages/deaths/datasets/deathsbyvaccinationstatusengland

Anyway, you can follow that trail if you want to dig deeper. All I did was a Google image search and dug through Twitter until I saw the tweet with the image and mention of the site where it came from. The Expose itself did not appear as one of the results of the Google image search.
