Scientists link Covid vaccines to rare neurological complications

Date:

According to the most comprehensive study of side effects from two jabs, the BioNTech / Pfizer and Oxford / AstraZeneca coronavirus vaccines are associated with seven rare neurological complications.

Using data from 32 million vaccinated adults in the United Kingdom, researchers estimated 38 additional people per 10 meters initially received. Oxford / AstraZeneca Shot Suffering from Guillain-Barré syndrome, it causes more pain and weakness in the limbs than the general population and is usually temporary.

They found Increasing risk Twenty-eight days after vaccination with BioNTech / Pfizer shots, the incidence of hemorrhagic stroke, a cerebral hemorrhage, was estimated at 60 per 10 million people. The increased risk was significantly higher in female patients.

A smaller dataset from Scotland confirmed an association between the AstraZeneca vaccine and Guillain-Barré syndrome, but did not find the same association between Pfizershot and hemorrhagic stroke.

Aziz Seek, a professor of primary care research and development at the University of Edinburgh, emphasized that adverse events are so rare that the incidence must be reported in the millions rather than in the thousands. Incidents were measured 28 days after vaccination or had a positive test result.

“None of these vaccine-related adverse events show a higher risk than the risk associated with infection,” he said.

In fact, people infected with Sars CoV-2, the virus that causes Covid-19, were at significantly higher risk for seven neurological conditions.

The infection causes an excess of 145 Guillain-Barré syndromes per 10 million people, and 123 extra events of encephalitis meningitis and myelitis, inflammation of the brain and spinal cord. People infected with the virus were at increased risk of hemorrhagic stroke, but only in the first 7 days after a positive test result.

Data include people vaccinated from December to May, including 20 m vaccinated with AstraZeneca and 12 m vaccinated with Pfizerjab, with 2 million people tested positive for Covid-19. It was compared. Scientists will study the incidence in the population after two doses.

The AstraZeneca vaccine has become associated with another very rare vaccine Side effects of blood coagulationIn some countries, shots have been abandoned or restricted for use by young people.Pfizer and Modana mRNA vaccines Related It is associated with rare heart inflammation, especially in young men.

Julia Hippisley-Cox, A professor of clinical epidemiology at Oxford University, who was not involved in the development of the Oxford / AstraZeneca vaccine, had previously pointed out an association with Guillain-Barré syndrome, which is “the largest and most reliable study internationally.” Said. That kind.

Pfizer said it took the vaccine-related adverse events “very seriously” and collected information to send to regulatory agencies. “Hundreds of millions of people around the world are vaccinated with our vaccine,” he added.

AstraZeneca did not respond to requests for comment.
