A doctor has explained the symptoms of the blood clots being linked with the Oxford AstraZeneca Covid-19 coronavirus vaccine.
Dr Amir Khan has warned that anyone suffering from prolonged headaches, nausea or loss of vision for more than four days after having the jab should seek medical attention as it could be a warning sign of a potential blood clot.
The GP from Bradford was joining Good Morning Britain hosts Adil Ray and Ranvir Singh to discuss viewer concerns about the AstraZeneca vaccine after trials at Oxford on children were paused as the UK's independent medicines regulator revises the links between the vaccine and a small number of blood clots in adults.
The AstraZeneca vaccine has been suspended in some countries across the world in those under-55 after worries blood clots in the brain have been formed in a small number of adults.
Dr Amir Khan was asked by Ranvir: "How do you know if you're feeling it? If you've got one?"
Dr Amir replied: "It is very rare these very specific blood clots in the brain, it's common to get minimal side effects after having the vaccine such as a temperature, fevers, chills, headaches, but if your headaches persist beyond four days after having the vaccine then you should seek medical help.
"Other symptoms include blurred vision and nausea."
Dr Amir then warned of more serious repercussions if these warning signs are given time to develop, adding: "As time develops, if you don't get treatment, that could lead on to seizures and comas.
"Headaches, blurred vision, nausea, particularly after four days is when you should seek medical help."
Adil then asked: "Can it happen at any time after four days, Dr Amir? Is there a time - is there a moment you can go 'Right, I'm clear of this now? It's been a few weeks, I should be okay?'"
Dr Amir added: "So yeah, four days onwards, it's thought to be around 10 days but anything beyond four days, you should seek medical help."
Earlier in the show, Dr Amir did reiterate that the likelihood of a blood clot forming as a direct result of having the Oxford AstraZeneca vaccine currently stands at 1 in 100,000, whereas the likelihood of dying from Coronavirus is a much greater risk.
That echoed calls from Prime Minister Boris Johnson and the UK regulator, Medicines and Healthcare Products Regulatory Agency (MHRA) which said the benefits of the jab continue to outweigh any risk.
Good Morning Britain returns at 6am every weekday morning on ITV.
