For the second year in a row, major global companies such as Google, Nandos and Tesco are dropping A, O and B from their logos to support the NHS Blood and Transplant campaign The Missing Type to raise awareness about donating blood.

The letters signify different blood types.

Mike Stredder, director of blood donation at NHS Blood and Transplant, said: “Every donation can help or save up to three patients and last year in England alone 900,000 people gave blood – helping up to 2.7 million patients.”

The amount of blood being donated has dropped globally between 2005 and 2015 by a fifth, and in the UK, new volunteers have dropped by 40% in the last 10 years.

Under the video it says: “Around the world, As, Bs and Os are disappearing. This year blood donor organisations from 21 countries – covering 1 billion people – are coming together for our Missing Type campaign. We are asking everyone to ‘drop’ the letters of the main blood groups to show support for blood donation and register to give blood.”

This year, the campaign has grown with 21 countries including Australia, America, Belgium, Ireland, South Africa, Japan taking part.

A number of organisations supported the campaign in the UK, including Microsoft, Guys & St Thomas’ NHS Foundation Trust, Boots, Warburtons, Manchester City, Santander, Transport for London and Odeon.

Donated blood is vitally important for hospitals to be able to undertake lifesaving work.

“In England alone we need almost 200,000 new donors, especially from blood groups like O negative and A negative, younger and black and South Asian donors,” says NHS Blood and Transplant.

PR Week said: “In the UK, people can start donating blood from the age of 17, but more than half of donors were aged 45 and over last year. Black donors are also in particularly short supply – 3.5 per cent of the population of England is black African or black Caribbean, but they accounted for fewer than one in every 150 donors.”
