Scientists believe they have found the “trigger” that causes the side effect of blood clotting following the Oxford-AstraZeneca Covid vaccine.

The research team – in Cardiff and the US – have demonstrated in detail how a protein in the blood is attracted to a key component of the vaccine.

They suspect this starts a chain reaction, involving the immune system, which ultimately causes the dangerous clot.

The Oxford-AstraZeneca vaccine is estimated to have saved around one million lives from Covid.
