Brain Clots ‘More Likely’ With Covid Infection Than Vaccine

Brain Clots ‘More Likely’ With Covid Infection Than Vaccine, According to New Study.

A NEW study suggests that brain clots are more likely with Covid infection than in people who have been vaccinated for the potentially deadly virus. The study suggests that the chances of developing a serious brain clot called a cerebral venous sinus thrombosis (CVST), come in at eight to 10 times higher in Covid patients than in people who get a vaccine, as reported the BBC.

The study was only based on the Pfizer or Moderna vaccine, and was based on data from the United States. The Oxford research team believes that the study should reassure people about being vaccinated.

The study investigated the number of CVSTs found in patients diagnosed with coronavirus, in the two weeks following the diagnosis. It also looked at the number of cases that were found in the two weeks after people had received the first coronavirus vaccine.

Paul Harrison, professor of psychiatry at the University of Oxford, speaking about the study said, “Firstly, Covid-19 markedly increases the risk of CVST, adding to the list of blood clotting problems this infection causes.

“Secondly, the Covid-19 risk is higher than seen with the current vaccines, even for those under 30; something that should be taken into account when considering the balances between risks and benefits for vaccination.”

Prof Beverley Hunt, of Thrombosis UK, explained how the clots experienced by Covid patients and those experienced by vaccinated people appear to be caused by different mechanisms. She said, “Patients who are hospitalised with Covid-19 have very pro-thrombotic (sticky) changes in their blood, which persist after they have been discharged. This will lead to an increased rate of blood clots.

“The mechanism for the very rare blood clots and low platelet counts seen after the AstraZeneca vaccine is different. It is associated with an immune response.”

The study still needs to be formally reviewed and should be considered as a work in progress according to researchers.
