ChorogUsan's Life-Saving Receipt turns grocery slips into vaccine lifelines — ADFEST Gold

All children under 12 in South Korea can get essential vaccinations free, but only 55.2% of migrant-background children complete them versus 96.4% of Korean children — language barriers and hard-to-find information keep families out of the system.

Turn the grocery receipt into a life-saving medium: when a parent buys childcare items, print vaccine guidance in their language with a QR code to free care.

DMINUSONE wrote a conditional receipt algorithm and installed it on POS systems in local stores in migrant hubs such as Icheon, Gimpo and Incheon. When a shopper buys diapers, formula or baby lotion, the receipt prints vaccination and health guidance in their native language, with a QR code linking to free vaccination, medical interpretation and counseling services.

Around 70,000 receipts reached migrant families and 80% of previously missed migrant-background children went on to get checkups and vaccinations — 102 children were linked to medical institutions and 80 received care. More than 1,000 institutions joined, generating 101.6M impressions; the work won ADFEST Media Lotus Gold, Spikes Asia Healthcare Gold and two Cannes Lions Silvers.

South Korea gives every child under 12 free essential vaccinations, yet a 2024 health survey found only 55.2% of migrant-background children complete them, against 96.4% of Korean children. The care is free; the barrier is a medical system built around the Korean language, with complex, hard-to-find information that pushes migrant families into a health blind spot.

DMINUSONE's insight was that migrant families cluster by country of origin and rarely move beyond their living radius, and the one place nearly every migrant parent visits is the local grocery store. The agency turned that store into a media channel: a conditional receipt algorithm, installed in shops across hubs like Icheon, Gimpo and Incheon, prints health guidance only when a shopper buys childcare products such as diapers, formula or baby lotion. The message appears in the parent's native language, with a QR code linking to vaccination support, medical interpretation and counseling.

The campaign reached about 70,000 families through receipts and more than 1,000 institutions joined the effort. According to ChorogUsan, 102 previously unserved children were linked to medical institutions and 80 received checkups and vaccinations. The work won ADFEST 2026 Media Lotus Gold, Spikes Asia 2026 Healthcare Gold, two Cannes Lions 2026 Silvers and a Clio Health Award, and was reported in migrant families' home countries including Vietnam and Ukraine.

The insight treats the physical receipt — the only touchpoint every migrant parent already holds — as the media, so no new habit or app is required.

Printing guidance only on childcare purchases makes the message conditional on a clear signal of need, keeping it relevant instead of noise.

Native-language messaging plus a QR code to interpreters and free services removes both the language barrier and the 'where do I go' barrier at once.

Placing the system in grocery stores inside migrant hubs means the medium travels with the community rather than expecting families to find it.

The results loop back into the cause: 102 children connected to care and 80 vaccinated or screened, with coverage in families' home countries amplifying trust.

Find the touchpoint your audience already touches daily and make the message conditional on a behavior that signals need — relevance at the point of purchase reaches audiences no campaign can target.

The campaign ran from July 2025 in stores across migrant hubs and grew beyond advertising: over 1,000 institutions (40 regional offices, 68 partners, supermarket chains) joined, generating 101.6M impressions in Korea and coverage in Vietnam and Ukraine. It reached the National Assembly, prompting a policy forum on migrant children's healthcare access. By mid-2026 it had won ADFEST Media Gold and Silver, Spikes Healthcare Gold and Bronze, two Cannes Lions Silvers, a Clio Health Silver and Korea Advertising Awards; ChorogUsan continues its vaccination and interpretation programs.
