Give Blood NHS has found a novel way to encourage people to donate during #NationalBloodWeek.

"There’s a decline year-on-year of the number of new people donating, and more than half of current donors are over 45," Give Blood NHS's head of PR, Andrea Ttofa, told BuzzFeed News.

"It’s important to take action now in order to maintain a safe supply of blood for the future," she continued.


The campaign also encourages people to drop the As, Os, and Bs from their Twitter names to raise awareness of the need for new blood donors.

A number of brands have embraced the campaign.

"We have the biggest social media following of any blood service in the world and a very engaged community, but they’re often people who have already donated themselves," Ttofa said.

The NHS says having a strong supply of all blood types is essential in treating a number of illnesses.

"This is about always being able to provide for the future," Ttofa said.
