South Korea probes deaths of two who received AstraZeneca COVID-19 vaccine

South Korean authorities said on Wednesday they are investigating the deaths of two people, both with pre-existing conditions, who died within days of receiving AstraZeneca’s COVID-19 vaccine.

A 63-year-old nursing home patient with cerebrovascular disease, developed symptoms including high fever, after being given the vaccine four days ago, Korea Disease Control and Prevention Agency (KDCA) Director Jeong Eun-kyeong told a briefing.

The man was moved to a larger hospital on Tuesday, but died after showing symptoms of blood poisoning and pneumonia, Yonhap news agency reported.

Another nursing home patient in his 50s with a cardiac disorder and diabetes died on Wednesday after suffering multiple heart attacks, having received the vaccine a day earlier, the agency said.

KDCA said it is investigating the cause of the deaths, but did not confirm any causal relationship to the vaccine. The agency earlier said it will provide compensation of over 430 million won ($383,466) for deaths from the COVID-19 vaccine.
