Your eyes aren't playing tricks on you – something very important is missing here: the A, the B and the O. This is exactly what the worldwide awareness-raising campaign of the Red Cross blood donation services is about in 2021: Under the name "#missingtype – you only notice it when it's gone", the blood donation services want to raise awareness of the consequences of the lack of certain blood groups using the missing letters.

You only notice it when it's gone. For people who need blood donations, however, that could be too late. That is why we call on you today on World Blood Donor Day to donate your A, B and O. Give blood – and save lives!
