I believe only one person has died and unfortunately she had a number of other health issues. Two or three others have already been released from hospital, there are varying degrees of concern with clotting (which may also depend on other health issues, don’t know). You’d actually need a much larger sample to realistically assess individual risk related to particular ailments, that research may well have started somewhere in the world but 11 cases doesn’t provide a statistically valid sample. And we don’t really want more!
