A study published in the “Nature Medicine Journal” stated that “Covid-19” disease is more likely to cause damage to the nervous system than vaccines, according to the “Bloomberg” agency.
As part of the study, which was led by the University of Oxford, health records of 32 million people in England were analyzed to determine the risks of rare conditions in the brain before and after the result of positive tests for “Covid” or receiving the first dose of the “Pfizer-Biontech” vaccine, according to what I reported. German news agency.
The researchers compared the incidence of neurological complications in specific time periods. While vaccines have been shown to lead to an increase in neurological complications, such as Bell’s palsy and Guillain-Barré syndrome.
The study found that Covid poses a greater risk. The rare cases of these complications have prompted many countries to restrict the use of the AstraZeneca vaccine, which is produced by the University of Oxford, with older groups.
But there are several limitations to the study, for example, only the risks associated with the first dose of the “AstraZeneca” vaccine or the “Pfizer-Biontech” vaccine were examined, as the data on the second dose were limited at the time of preparing the study.
“Covid-19 vaccines are very effective in reducing the risk of very severe complications of COVID-19 infection,” said study co-author Julia Hebesley-Cox.
US regulators added Guillain-Barré syndrome to the list of rare side effects of the AstraZeneca vaccine last week.
