Deceased AstraZeneca trial volunteer didn’t receive vaccine

A participant who died during a trial of AstraZeneca Plc’s Covid-19 vaccine in Brazil hadn’t received the company’s shot, according to a person familiar with the matter.

Another vaccine maker, Johnson & Johnson, said earlier this month that it would pause its trial to investigate an illness in a study participant. Both the AstraZeneca and J&J vaccines are based on adenoviruses, cold germs that researchers have used in experimental therapies for decades.
