The new facility based in the cathedral Crypt can accommodate eight patients at any one time, and it is hoped around 1,700 people will be vaccinated each week.
The first patients received their Covid-19 jabs on Monday (January 18) when it opened its doors to become the latest large-scale vaccine centre in the UK.
The use of the cathedral has been greeted as a huge boost to Lancashire's vaccine roll-out, with thousands of people within a 45-minute drive of Blackburn to be invited for their vaccine at the site in the coming weeks.
Below are pictures from inside the cathedral, where NHS staff and volunteers have been busy administering the potentially life-saving jab to patients aged 80 and over.
