According to a study published Thursday by Oxford University, the risk of developing rare clots is higher for people who get COVID-19 than for people who are vaccinated.
The chance of getting cerebral venous thrombosis – the condition that prompted federal health officials to stop using the Johnson & Johnson vaccine this week – is up to 10 times higher after being infected with the coronavirus that after receiving a shot. according to the study.
“[Findings] it must be taken into account when considering the balances between the risks and benefits for vaccination, ”Paul Harrison, head of the Oxford group of translational neurobiology, said at a news conference on Thursday.
During the study, which was used to develop the AstraZeneca vaccine in Europe, the researchers examined the number of coagulation cases in the two weeks following the diagnosis of COVID-19.
They also investigated how many people suffered from the disease two weeks after the administration of a single dose of the Pfizer, Moderna and AstraZeneca vaccines.
The researchers found that the risk of developing the disease was 10 times higher after contracting COVID-19 than after receiving Pfizer or Moderna shots and eight times higher after receiving the AstraZeneca puncture.
The study did not include any data on the Johnson & Johnson vaccine, which was arrested by federal health officials Tuesday after six women reported suffering from clotting, including a 45-year-old girl who died.
Like the Johnson & Johnson vaccine in the United States, AstraZeneca’s sting has dropped due to possible links to brain blood clotting in Europe.
Denmark has stopped using AstraZeneca after an investigation “showed real and serious side effects”, according to health officials. Other countries have limited the use of the vaccine to older age groups, who appear to be less affected by clots.
