World Blood Donor Day Campaign: How Missing Type Made Blood Groups Disappear
Published · By Gaurav Phogat
World Blood Donor Day falls on 14 June. Its best-known campaign, NHS Blood and Transplant’s Missing Type, removed the letters A, B and O from brand names across England in the week leading up to the day and roughly tripled new donor sign-ups. The lesson: when you show people what is missing, they notice the gap and step in to fill it.
About World Blood Donor Day
World Blood Donor Day is held every year on 14 June, the birthday of Karl Landsteiner, the Nobel laureate who discovered the ABO blood group system. It was first organised in 2004 by the World Health Organization, the International Federation of Red Cross and Red Crescent Societies, the International Federation of Blood Donor Organizations and the International Society of Blood Transfusion (Wikipedia). WHO uses the day to grow regular, voluntary, unpaid donation, to thank donors and to urge governments to invest in national blood programmes. The 2026 slogan is “One Drop of Humanity. Give Blood. Save Lives.” (WHO). For hospitals with a blood centre, it is the clearest annual moment to recruit first-time donors.

The problem it had to solve
Fewer new people were coming forward to give blood. NHSBT’s reveal message was that 40% fewer new donors had come forward than a decade earlier, and it said it needed 204,000 new donors that year (NHSBT). A shortage that has not happened yet is hard to make visible. Appeals for blood are familiar enough to be ignored.
The idea in one line
Take the blood group letters A, O and B out of everyday life, so people feel the absence before you explain it.
How it worked
In a teaser phase, organisations quietly dropped the letters from their branding. Waterstones, Odeon, Green and Black’s, NOW TV and GAME were among the first. The reveal then explained the gaps and asked people to register as donors. By World Blood Donor Day about 1,000 businesses had joined, including Google, O2, Microsoft, McDonald’s, British Airways, Coca-Cola, Arsenal, Santander, Nando’s and Starbucks (NHSBT). The Downing Street sign and the Church of England took part too (NHSBT).
In 2016 the idea went global: 25 blood services from 21 countries ran it from 16 August, with Royal Mail adding a special postmark (NHSBT).
Results
NHSBT reported 30,620 new registrations between 5 and 14 June 2015, about 20,000 more than in 2014 and the highest total for any National Blood Week. 59% of registrants were aged 17 to 34, and Black, Asian and minority ethnic sign-ups rose from 832 to 2,025. The campaign reached a combined social audience of 147 million, and #MissingType was used more than 21,000 times (NHSBT). In 2016, about 24,000 people in England signed up over two weeks, double the previous fortnight, and 46,000 came forward across nine reporting countries (NHSBT). All of these are figures reported by the campaign owner.
What makes it stand out
- Insight: absence is more noticeable than another appeal.
- The distinctive asset costs nothing: three letters everyone already knows.
- Partners carried the media: each brand’s logo change was the ad.
- Built-in timing: a week of momentum ending on World Blood Donor Day.
- Easy to copy, which is why 21 countries could adopt it a year later.
Criticism and limits
Registration is not donation. The published results count sign-ups, and I could not find a verified figure for how many of those people went on to give blood, or kept giving. The numbers are NHSBT’s own, with no control group. The idea also depends on big brands saying yes; without about 1,000 partners it would have been a clever logo on one website. And NHSBT’s own 2016 release states the decline in new donors with two figures that do not match (24.4% and 27.6%), a small reminder to check campaign statistics before reusing them.
Would it pass in India today?
Yes, comfortably. The creative uses no patients, no testimonials and no superiority claims, so clauses 8.1(ii), 8.1(iii) and 8.1(v) of the NMC 2026 guidelines are not engaged. It is health education and a public call to action, which clause 8.2 allows. The care points are data and claims: a donor registration form must collect only what is needed, with clear consent under the DPDP Act, and any shortage figures you quote must be sourced to avoid misleading claims under ASCI rules.

What I take from this
Much of the blood donation creative I see leans on a drop of blood, a smiling donor or a hospital bed. Missing Type shows that the stronger move is to change something people already see every day and let them work out why. The second lesson is about the calendar: NHSBT did not treat 14 June as a single post. It built a week, with a teaser, a reveal and a peak on the day itself, so that the day became the payoff rather than the starting point. A hospital blood centre can plan the same arc with very little money, as long as the registration step at the end is short and works on a phone.
What an Indian hospital can borrow for World Blood Donor Day
- Missing letters on your own channels (Low: under Rs 1 lakh). Channel: hospital website header, social profile images, lobby signage and WhatsApp channel, from 7 to 14 June. Drop A, B and O from your own name and signage, then reveal the reason with a link to book a donation slot at your blood centre. Compliance: health education and facility facts are allowed under clauses 8.2, 8.3 and 9.1 of the NMC 2026 guidelines; no donor or patient testimonials (8.1(ii)).
- Neighbourhood brand coalition (Mid: Rs 1 to 10 lakh). Channel: local cafes, pharmacies, colleges and housing societies changing their signage and posts, plus a shared hashtag and a city PR push. Each partner points to the same donation camp page. Compliance: partners must not imply clinical endorsement; keep claims to verifiable facts (ASCI); camp registration forms need explicit, purpose-limited consent (DPDP Act).
- Group-wide donor drive with follow-through (High: above Rs 10 lakh). Channel: multi-city digital campaign, outdoor and corporate camps, plus SMS and email reminders to registrants. Measure donations, not just sign-ups, and publish anonymised totals afterwards. Compliance: reminders only to people who consented to be contacted (DPDP Act); no “No.1 blood bank” style claims (clause 8.1(iii)); label any AI-made visuals (clause 7.2).

Questions people ask
WHO’s 2026 slogan is “One Drop of Humanity. Give Blood. Save Lives.” The day is held on 14 June each year, Karl Landsteiner’s birthday.
NHS Blood and Transplant created Missing Type with the agency Engine Group. It first ran in England in June 2015, during National Blood Week.
It made an invisible shortage visible using three letters everyone knows, and about 1,000 brands carried the message on their own logos. NHSBT reported roughly three times as many new donor registrations as the previous year.
Make the need visible on your own channels, link straight to a donation slot or camp, get local partners to amplify it, and follow up with consenting registrants so sign-ups turn into donations.
