It is believed that the AstraZeneca vaccine saved the lives of one million people in the world

Scientists believe they have found the “factor” that leads to very rare cases of blood clots after receiving the Oxford AstraZeneca vaccine against the Corona virus.

A team in Britain and the United States has shown in great detail how a protein in the blood is attracted to a key component of a vaccine.

And they see that this process sets off a chain of reactions, in the immune system, that can end with dangerous clots in the blood.

The vaccine is believed to have saved 1 million people from Covid disease.
