An investigation is ongoing after Lisa Shaw, a local radio broadcaster with BBC Radio, died of a blood clot on the brain at the age of 44, just weeks after receiving the AstraZeneca coronavirus vaccine.

In a tweet by BBC Radio Newcastle last Sunday, May 23, Shaw’s death was confirmed, with the station noting that everyone at the station was “devastated” by the award-winning host’s death on May 21.

“She was a brilliant presenter, a wonderful friend and a loving wife and mum,” the tweet continued.

On Thursday, May 27, Shaw’s family confirmed that the BBC host had been given the AstraZeneca vaccine and experienced “serious headaches” a week later, which progressed to a blood clot on the brain, according to the National File.

The BBC Radio host was not known to have any underlying health issues.

“She was treated by the Royal Victoria Infirmary’s intensive care team for blood clots and bleeding in her head. Tragically, she passed away, surrounded by her family, on Friday afternoon,” the statement from the family said. “We are devastated and there is a Lisa-shaped hole in our lives that can never be filled. We will love and miss her always. It’s been a huge comfort to see how loved she was by everyone whose lives she touched, and we ask for privacy at this time to allow us to grieve as a family.”

Shaw’s death will be investigated, according to a “fact-of-death” certificate from Newcastle senior coroner Karen Dilks, with “complication of AstraZeneca COVID-19 virus vaccination” being a possible reason in her death.

The Oxford-AstraZeneca vaccination has been linked to a specific type of blood clot.

They are known as cerebral venous sinus thromboses (CVSTs), and what sets them apart is that persons with CVSTs frequently have low platelet counts (the building blocks of clots) in their blood.

They are regarded as exceedingly rare (there have been 332 reported cases and 58 documented deaths), after nearly 35 million doses of the AstraZeneca vaccine have been given in the UK, BBC reported.

The Medicine and Healthcare Products Regulatory Agency (MHRA) said it was “saddened” to learn of the BBC host’s death from a blood clot, and that reports with a fatal outcome are fully evaluated by the MHRA, including an assessment of post-mortem details if available, as with any serious suspected adverse reaction [to the AstraZeneca vaccine]. Their “detailed and rigorous review into reports of blood clots occurring together with thrombocytopenia is ongoing,”  they further added.

Following concerns of lethal blood clots, the UK, along with other European countries, suggested that people under the age of 40 be offered an alternative to the AstraZeneca vaccine.

In the United Kingdom, there have been 332 reported occurrences of cerebral venous sinus thromboses (CVSTs) and 58 deaths linked to the vaccine as of this writing. CVSTs are a very unique sort of blood clot because the victims have very low quantities of platelets, which normally form a clot.
