A BRADFORD doctor says there is ‘no proven link right now’ between one of the Covid vaccines and blood clots.

The trial of the Oxford/AstraZeneca vaccine in children has been paused while regulators investigate reports of a rare form of blood clot among adults.

The University of Oxford said that no safety concerns have arisen from the trial itself.

But it is waiting for more information from the Medicines and Healthcare products Regulatory Agency (MHRA) before giving any more vaccinations.

Regulatory bodies from the UK, Europe and the World Health Organisation (WHO) are assessing data on the jab and a potential association with a rare form of blood clot.

The WHO and the European Medicines Agency (EMA) have confirmed they will publish findings later this week.

Appearing on today's Good Morning Britain, Dr Amir Khan explained that the data is being reviewed and we await its findings.

He said: “The EMA and WHO are looking at the global data on the Oxford vaccine to see if there may be a link between the vaccine and these very rare blood clots.

"The symptoms are headaches, nausea, blurred vision.

“There is no proven link right now. The data is being reviewed and they may restrict the use of the vaccine in the under-30s because these clots are more common in younger people, but we don’t know yet. We don’t know when they will come out with their statement, or publish their data.

“If you look at these numbers, it is a very rare event.

“In the UK, just over 18 million people have had Oxford vaccine, and there have been 30 people reported cases of these clots, seven people have sadly died of this out of the 30.

“Europe have taken a slightly different approach. Germany have halted their use of this vaccine. 2.7m people have been vaccinated with the Oxford vaccine and 31 people have reported this clot. Germany have been vaccinating younger people where this clot is more common.

“We are waiting for more data.”

Dr Khan added it is incredibly rare to get these specific blood clots in the brain. He added it is common to get minimal side effects after having the vaccine, but 'if your headache persists beyond four days after having the jab, then people, should seek medical help'.

The University of Oxford said in a statement: "Whilst there are no safety concerns in the paediatric clinical trial, we await additional information from the MHRA on its review of rare cases of thrombosis/thrombocytopaenia that have been reported in adults, before giving any further vaccinations in the trial.

"Parents and children should continue to attend all scheduled visits and can contact the trial sites if they have any questions."

The Prime Minister yesterday urged the public to trust the regulator on vaccine safety.

Boris Johnson said getting the population vaccinated was "the key thing", while he visited the AstraZeneca manufacturing plant in Macclesfield.

"On the Oxford/AstraZeneca vaccine, the best thing people should do is look at what the MHRA (Medicines and Healthcare products Regulatory Agency) say, our independent regulator - that's why we have them, that's why they are independent," he said.

"Their advice to people is to keep going out there, get your jab, get your second jab."

He added: "The best thing of all is to vaccinate our population, get everybody out getting the jab, that's the key thing and that's what I would advocate, number one".

The MHRA is also investigating reports of a very rare and specific type of blood clot in the brain, known as cerebral venous sinus thrombosis (CVST), occurring together with low levels of platelets (thrombocytopenia) following vaccination.

The former chief executive of the Medicines and Healthcare Products Regulatory Agency (MHRA) has said he has "no reservations" about the AstraZeneca vaccine.

Professor Sir Kent Woods told LBC radio: "The risks of Covid are much higher.

"The reason it is so difficult to be certain whether or not there is a cause-and-effect relationship, even in younger people, between the vaccine and these thrombotic events, these clotting events, is that there are such clotting events occurring in the background anyway."

He added: "It's not an unknown event."

A Government minister has said that getting the Oxford/AstraZeneca jab is safer than not being vaccinated.

Small business minister Paul Scully told Times Radio: "The regulator does not regulate drugs that it believes are unsafe.

"There's absolutely every evidence that you are safer taking the vaccine, you are more likely to survive, to live, to stay well.

"And this is the route out of our pandemic.

"So my message is, when you're invited to do so, as I did, and I've had my first jab, please do go and get that."
