Three cases of stroke have been diagnosed in the UK after doctors administered a vaccine from the British-Swedish company AstraZeneca. The Journal of Neurology Neurosurgery & Psychiatry writes
“Our observations show that vaccination with the AstraZeneca vaccine leads in some rare cases to the formation of not only venous but also arterial blood clots in brain vessels. Sometimes this results in the development of strokes even in young patients, which is something doctors should bear in mind”, – said Professor David Werring of University College London.
According to the professor, taking the AstraZeneca vaccine in some cases provokes the formation of blood clots not only in veins but also in arteries. The first patient to be diagnosed with a stroke was a 35-year-old woman. She started complaining of headaches about 6 days after the vaccination. Afterwards, she lost control of the muscles in the left side of her body.
The medics discovered that she had developed a massive blood clot in her middle cerebral artery, which triggered the ischaemia and caused a massive stroke. Despite doctors’ efforts, the patient slipped into a coma, after which medics pronounced her dead as a result of brain stem damage.
Two other patients, a 37-year-old woman and a 43-year-old man, presented with complaints of headaches and speech disorders. The symptoms were also associated with blood clots in internal arteries. However, the lives of the patients were saved by the use of clot-dissolving drugs.
Recall that the first reports of blood clots after vaccination with AstraZeneca’s drug began to appear in early April. A number of countries around the world have stopped immunisation with the drug, but the EU regulator later listed the occurrence of blood clots as a rare adverse event.
