SHANGHAI/GENEVA (Reuters) - Doctors in Shanghai are using infusions of blood plasma from people who have recovered from the coronavirus to treat those still battling the infection, reporting some encouraging preliminary results, a Chinese professor said on Monday.
A top emergency expert at the World Health Organization (WHO) said later that using convalescent plasma was a "very valid" approach to test, but that it was important to get the timing right to maximise the boost to a patient's immunity.
