London – A study by researchers at Oxford University in England suggests that the risks of experiencing dangerous and rare blood clots in the brain are much higher in those who catch coronavirus than those who receive either the AstraZeneca vaccine or the vaccines produced by Pfizer and Moderna in the US Research shows that the number of people suffering from clots after receiving vaccines given by US pharmaceutical giants seems very similar to the number of people receiving the rare condition after a shot of AstraZeneca, which was developed in conjunction with the Oxford Vaccination Institute.
A key finding of the research, revealed on Thursday as a “pre-printed” study that has not yet been analyzed by other scientists, was that the risk of experiencing a blood clot in the brain was about 95 times higher. greater for people who contract COVID-19 than in the general population.
This is yet another serious health threat associated with the disease and one that scientists have hoped will boost confidence in all major vaccines currently available in the Western world, as their research suggests that drugs pose a significantly lower threat of clotting. than the disease they have ‘It turned out he can handle.
“This is further evidence that the vaccine is helping people dramatically from the ravages of COVID-19,” said CBS News medical consultant Dr. David Agus of the CBS This Morning study.
The analysis of real-world data collected by the global health research network TriNetX and European agencies included information on hundreds of thousands of people who either caught COVID-19 or were offered AstraZeneca, Pfizer or Moderna Photos. Most data on mRNA vaccines, which are US drugs, come from the United States, while data on AstraZeneca vaccines come largely from Europe’s mass vaccination programs.
The data showed that about 4 in 1 million people who receive vaccines made in America suffer from cerebral venous thrombosis (CVD) or blood clots in the brain. With the AstraZeneca vaccine, which works in a different way and is similar to Johnson & Johnson fired, the research showed an incidence rate of about 5 out of 1 million.
This equates to a 10 times higher risk of CVT for people who get the coronavirus than for those who receive Pfizer or Moderna vaccines and 8 times higher for those who have been given the AstraZeneca vaccine.
“There are concerns about possible associations between vaccines and CVT, leading governments and regulators to restrict the use of certain vaccines,” said Paul Harrison, a professor of psychiatry and head of the Oxford Translational Neurobiology Group. “I came to two important conclusions. First, COVID-19 significantly increases the risk of CVD, adding to the list of blood clotting problems caused by this infection. Second, the risk of COVID-19 is higher than that seen with current vaccines, even for those under 30; which should be taken into account when considering the balances between the risks and benefits of vaccination. “
Research released by Oxford on Thursday found that about 39 out of every million people who contract COVID-19 are likely to experience brain clots. The scientists emphasized that the purpose of their research was not to compare vaccines, but to gather firm data on the risks of all vaccines compared to the risks associated with COVID-19 capture.
“The signs that COVID-19 is related to CVD, as well as portal vein thrombosis – a liver clotting disorder – are clear and we should take note,” said Dr. Maxime Taquet, another researcher in the Neurobiology Group. Translational.
As the figures used to determine the overall incidence rates have been constantly updated, the researchers emphasized that “all comparisons must be interpreted with caution, as data continue to accumulate”.
They also noted that it was not yet clear whether “COVID-19 and vaccines lead to CVD through the same or different mechanisms” and said that they would be the subject of their ongoing research.
