A patient of a long-term care hospital in South Korea with multiple underlying diseases died Wednesday after receiving the AstraZeneca vaccine against COVID-19, local media reported citing officials.
The 50-something patient was vaccinated Tuesday morning at the hospital in Goyang, outside of Seoul's northwestern border.
The patient began to show symptoms of heart failure and difficulty in breathing by the afternoon but recovered after being put under emergency care.
The symptoms recurred Wednesday morning before the patient died, according to the report.
Health officials said they have yet to determine whether the patient suffered side effects from the vaccine.
The patient's preexisting conditions included heart problems, diabetes and a stroke.
