South Korea on Monday confirmed its first case of blood clotting,as a direct side effect of AstraZeneca's COVID-19 vaccine.
The case involves a man in his 30s, working at a medical facility.
He was inoculated on April 27th.
Two weeks later, he developed a serious headache, which was later accompanied muscle cramps.
He was hospitalized, and was confirmed with thrombosis of the brain.
Thanks to early treatment, he is now in a stable condition.
This marks the first blood clotting case,where the authorities have confirmed causality with the vaccine.
"We've conducted platelet antibody tests on the patient. The results, which came out today, showed that he tested positive, based on which, we were able to confirm vaccine-induced thrombocytopenia."
Authorities stress the risk is relatively low.
So far,South Korea has seen only one case of blood clotting, out of some 3.3 million people who got the AstraZeneca jab.
That amounts to 0.3 cases per million.
In the UK, authorities say, it's roughly 9.5 cases, in every 1 million.
In the EU, it's 10 cases per 1 million people.
Health authorities also stress, that even when this very rare blood clotting case occurs, it can still be treated.

"Early detection is key when headaches or a tight chest lasts for long period of time, recipients could get blood test and imaging test if necessary. If confirmed with thrombocytopenia, anticoagulant drugs can be used"
Experts say,possible signs of blood clots could be severe headaches or stomachaches,… and recommend that vaccine recipients see a doctor,.. if symptoms last longer than three days.
