A 98-year-old scientist and his 85-year-old wife have recovered from the novel coronavirus on the same day after being treated for 18 days.
Mr. Han and his wife were diagnosed with the disease in February and transferred to the provincial hospital on February 24 after their conditions worsened.
Scientists believe the treatment works, in theory, by putting disease-fighting proteins from recovered patients into people still battling the illness.
The sick patients’ bodies can then use these proteins – called antibodies – as if they were there own, instead of having to make them from scratch.
