A report issued by the US Food and Drug Administration stated that six people have died during trials of a Coronavirus vaccine developed by the American pharmaceutical giant Pfizer and the German company Biontech.
The report explained in detail that four of the six deceased received a fake drug, and two were inoculated with the real drug.
It was also announced that one of the participants in the group of participants in the vaccine tests had obesity and atherosclerosis and died three days after taking the first dose of the drug.
The deceased second volunteer had a heart attack 60 days after the second dose.
Among the participants who received the placebo vaccine, two died as a result of a heart attack and a stroke, while the cause of death of two others is being determined.
Of the six deceased, three were over the age of 55.
In total, about 38,000 people over the age of 16 participated in these tests.
The US Food and Drug Administration had previously confirmed the effectiveness of the Pfizer and Biontech vaccine, and the documents said that the drug showed an adequate level of safety, and there are no obstacles to its use in emergencies.
