Yes — heirs in South Korea can continue a deceased person's vaccine-injury claim for added medical expenses. The Supreme Court's First Division confirmed that right on Oct.
23, 2026, ruling for the late Jeon Mo against the Korea Disease Control and Prevention Agency. Jeon developed Guillain-Barre syndrome, an acute paralytic nerve condition, after an influenza shot in October 2014. According to Aju Press, the court dismissed the agency's appeal and allowed added expenses beyond an earlier disability payment in the case described in Aju Press's account of the ruling.

What the Supreme Court decided
Jeon was vaccinated at a Yongin public health center in October 2014 and later required hospitalization. He received a first-degree disability classification in June 2015. His first compensation request was denied in September 2015, but he won in court in February 2021. That win brought about 325.78 million won for care from October 2014 through July 2015.
When Jeon later sought 136.18 million won plus 10.09 million won in nursing costs, the agency refused. According to Aju Press, those figures and dates are set out in Aju Press's account of the ruling. The court held that an earlier disability lump sum does not automatically block added medical expenses. Pre-payment expenses remain preserved. Active treatment for recurrence or worsening also remains eligible, with limits only on duplicate conservative-treatment costs after payment.
Who can file under South Korea's vaccine scheme
South Korea uses a no-fault vaccine system, meaning recipients do not have to prove negligence to seek payment. The law covers disease, disability, or death linked to vaccination. Claims may be filed by a recipient's representative or by a deceased recipient's estate, with no filing charge. That structure is described by the Oxford Faculty of Law in its summary of the system in the Oxford summary of South Korea's scheme.
For readers, the key point is succession. If the injured person dies, heirs do not lose a pending medical-expense claim solely because of the death. The final-round plaintiffs here were the heirs of the injured person. They pursued the denied request for additional medical costs after his death. The ruling therefore matters most to families carrying ongoing bills from a severe post-vaccination injury.
Why heirs still must prove a causal link
Permission to sue is not a guarantee of payment. Heirs still must show that vaccination contributed to or aggravated the injury or death. Medical records and causation evidence remain central. A Seoul Administrative Court decision from July 11, 2025 illustrates that test.
In Case 2023GuHap73595, a Moyamoya-related hemorrhage seven days after COVID vaccination was held compensable after agency denial. That outcome is discussed by IPG Legal in IPG Legal's review of the Moyamoya case. Courts reject heir claims without medically recognized causality. The practical limit is therefore narrow. Heirs can continue the claim, but they must connect the vaccine to the harm claimed.
What families should document
Separate costs by time period. Keep bills from before the disability payment apart from later bills. Flag hospital stays, active interventions, and treatment tied to recurrence or worsening.
For later conservative care, avoid claiming the same costs twice. The court allowed limits on duplicate post-payment conservative-treatment costs. Itemized invoices, admission records, nursing notes, and physician statements help show which costs are new.
- Group receipts into pre-payment, recurrence or worsening, and ongoing care
- Keep hospital, pharmacy, rehabilitation, and home-nursing invoices separate
- Save disability classification, court judgment, and prior payment records
- Ask the treating doctor to link each active treatment to recurrence or worsening
Frequently Asked Questions
Does this ruling create a U.S.-style class action?
No. It concerns South Korea's administrative vaccine-compensation claim and court review of a denial, not a consumer class settlement.
Can heirs file a new injury claim after death?
The ruling addresses continuation of a deceased victim's pending medical-expense claim. New death-benefit requests still need proof that vaccination contributed to or aggravated death.
