Scientists could be moving closer to understanding why the Oxford-AstraZeneca Covid-19 vaccine causes a risk of blood clots in some people.
A German researcher has suggested that an ingredient in the vaccine may cause
blood vessels to leak, sparking
a chain reaction in the immune system.
There are, however, competing theories to the proposal put forward by Dr Andreas Greinacher, of the University of Greifswald, which follows studies in mice.
Finding the cause could offer multiple benefits, according to experts. It could allow researchers to amend the vaccine to prevent the clotting risk, and help doctors to treat affected individuals.

Scientists world-wide are racing to understand why Covid-19 vaccines from AstraZeneca PLC and Johnson & Johnson are causing rare but potentially deadly blood clots.
Determining the connection would help patients, doctors and health agencies better assess any risks posed by the vaccines and safely calibrate their use. In recent weeks, the U.S., the Canadian province of Ontario and several European countries including Norway and Denmark either paused or completely halted rollouts involving these vaccines. Understanding the cause is of highest importance for the next-generation vaccines, because [the novel] coronavirus will stay with us and vaccination will likely become seasonal, said Eric van Gorp, a professor at Erasmus University in the Netherlands who heads a group of scientists studying the condition.
A preservative in AstraZeneca s Covid vaccine may trigger a rare overreaction from the immune system that causes blood clots, a scientist has claimed.
Tiny numbers of people given the jab or the one made by Johnson & Johnson have developed a clotting condition that spooked some countries into turning their backs on it.
The reasons for this have been unclear but one German expert has suggested it may begin with a chemical used to make the vaccine.
EDTA, or ethylenediaminetetraacetic acid, might trigger an immune overreaction by forming clumps using platelets in the bloodstream.
EDTA commonly used in medicines and cosmetics may make more ingredients of the intra-muscular jab leak into blood vessels.

Blood expert zeros in on vaccine blood-clotting cause
A German blood expert has conducted research that he says sheds light on why the Johnson & Johnson and AstraZeneca vaccines have triggered rare but serious blood clot conditions in a few vaccine recipients.
Andreas Greinacher, a researcher at the University of Greifswald, believes so-called viral vector vaccines could cause an autoimmune response that leads to blood clots in a small number of people. He believes that reaction could be tied to stray proteins and a preservative used in the vaccines.
