WHO–ENHYPEN Blood Donation Campaign: Who Can Donate in South Korea?

Short answer: WHO and ENHYPEN highlighted voluntary blood donation in Seoul on October 23, 2026, but the campaign did not change South Korea’s donor rules. A pledge or meeting the headline age and weight thresholds does not guarantee eligibility. Korean blood centers make the final decision after identity checks, a questionnaire, vital signs, hemoglobin testing, and review of illness, medicines, vaccination, procedures and travel.

What happened in Seoul?

The WHO–ENHYPEN collaboration began on World Blood Donor Day, June 14, 2026. WHO reported that its “Drop Your Drop” campaign had received more than 9,000 pledges across 177 countries, including more than 3,250 participants who identified themselves as ENGENE.

During an October visit to a Korean Red Cross donation center, every ENHYPEN member went through donor-eligibility screening. JAY and JUNGWON then donated plasma. That sequence matters: a public pledge is an invitation to check eligibility, not permission to bypass screening.

The October announcement celebrated outreach. It did not create a new Korean age limit, shorten donation intervals or make every campaign participant eligible.

What are the basic age ranges in South Korea?

The Korean Red Cross Blood Services lists these starting ranges:

• Whole blood: ages 16–69
• Plasma donation: ages 17–69
• Platelet and platelet-plasma donation: ages 17–59, with additional type-specific restrictions
• Age 65 or older: donation is limited to people who donated between ages 60 and 64.

These are entry criteria, not a complete eligibility test. The donation type, present health and personal history can narrow the answer.

What is checked at the donation center?

The general minimum weight is 50 kg for men and 45 kg for women. Korean Red Cross guidance also lists systolic blood pressure from 90 to 179 mmHg, diastolic pressure below 100 mmHg, pulse from 50 to 100 beats per minute and temperature no higher than 37.5°C.

Hemoglobin must be at least 12.5 g/dL for whole blood and 12.0 g/dL for component donation. A result below the cutoff may defer donation that day. It is a safety screen, not a full diagnostic evaluation of anemia or its cause.

Specific collection volumes and component procedures can add other requirements. An online questionnaire or reservation never overrides the assessment made at the center.

How long must donors wait between visits?

After whole-blood donation, the standard interval is eight weeks. After a component donation, it is two weeks. In the preceding one-year period, whole-blood donation is limited to five times, while platelet and platelet-plasma donations are limited to 24.

The next eligible date shown in the Korean system can be later than this simple calculation. Previous test results, medicines, illness and the combined donation history can add a deferral. Korean Red Cross records and staff guidance are therefore more reliable than counting days independently.

Why do medicines, vaccines and travel matter?

Korea’s Blood Management Act enforcement rules identify circumstances in which blood should not be collected to protect both donor and recipient. Temporary or longer deferrals may follow certain infections, medical conditions, medicines, vaccines, procedures, test results or stays in malaria-risk areas.

Examples in Korean Red Cross guidance include isotretinoin for acne and certain medicines for hair loss or prostate conditions, which can carry post-treatment waiting periods because of potential fetal effects. Travel screening depends on the country, specific region, dates and duration—not merely whether someone crossed a border.

Do not stop a prescribed medicine just to donate. Bring the exact product name, last dose and travel details to screening. Treatment decisions belong with the prescribing clinician, while the blood service determines donation eligibility.

What should a donor do before and after?

• Bring accepted photo identification and answer the electronic questionnaire accurately.
• Avoid arriving fasting, sleep-deprived or unwell.
• Rest and drink fluids after donation.
• Korean Red Cross advises avoiding alcohol that day, smoking for one hour, and saunas, steam rooms or prolonged hot baths.
• Dizziness or low blood pressure can occur, often in the first one to two hours. Avoid driving or operating equipment during that period and avoid strenuous exercise for 12 hours.

Limits of this explainer

• The WHO release describes a participation campaign, not a Korean rule change.
• Headline age, weight and hemoglobin values cannot determine an individual’s eligibility.
• Medicine, vaccine, disease, procedure and travel deferrals vary by exact product, event and date.
• These criteria describe donation in South Korea and should not be transferred to another country.
• An online screening result or appointment is not the final medical decision.

The useful takeaway

The campaign may give young people a reason to consider donating, but safe blood donation starts with accurate screening. In South Korea, choose the intended donation type, review current Korean Red Cross criteria and complete on-site assessment. A safe, repeat donor contributes more than a social-media pledge—without putting the donor or recipient at avoidable risk.
