According to Professor Vanassche, a rare side effect has been known for some time with immune activations such as vaccinations, but also infections or inflammation.
An antibody is randomly formed that activates platelets and thus leads to a blood clot. “This extremely rare phenomenon can therefore occur after vaccination, but no link has yet been established with a specific type of vaccine,” Vanassche emphasizes.
The chance that a thrombosis will occur with a COVID-19 infection is also many times higher than the chance of this rare complication after vaccination: there are no precise figures, but between 10 to even 60 percent of hospitalized corona patients have a thrombosis. through. “Anyone concerned about a thrombosis should therefore be vaccinated against COVID-19”, Vanassche concludes.
At the moment, no risk factors have yet been established for the side effect after vaccination. “No sex-linked factors have yet been identified in this side effect,” says Vanassche. “Classical thromboses, on the other hand, are much more common in women. The difference is even greater in the younger age groups.”
