Three young people have suffered strokes and one has died soon after receiving the Oxford/AstraZeneca vaccine, prompting a call for doctors to be vigilant.
Two women in their 30s and a man in his 40s suffered clots in their large arteries, leading to ischaemic stroke, but experts have stressed the chances were still extremely small.
A team of experts from the National Hospital for Neurology and Neurosurgery at University College London (UCL) Hospitals NHS Foundation Trust, and other medical organisations said the NHS must look out for patients with ischaemic stroke within about one month of vaccination.
