Scientists ‘find cause’ of rare blood clots linked to Covid vaccines - and how to solve it

Scientists claim to have identified the cause of rare blood clots which have been linked to some Covid-19 vaccines.

Concerns have been raised over the AstraZeneca and Johnson & Johnson vaccines, after some people developed blood clots after their jab, but German researchers have said the current jabs could be modified to make them safer for future patients.

What is causing the blood clots?

A research team at the Goethe University in Frankfurt claim, in a study not reviewed by experts, the rare blood clots are caused by “floating mutant proteins”, which can occur when a vaccine sends the spike protein of the Sars-Cov-2 virus into the wrong part of a cell.

Lead scientist Rolf Marschalek said the issue lies with the adenovirus vectors, which both the AstraZeneca and Johnson & Johnson vaccines use to send the spike protein into the body.

This method then sends the spike protein into the cell nucleus, rather than the cytosol fluid inside the cell. Once inside, parts of the spike protein then split apart creating mutant versions.

These mutations are unable to bind to the cell membrane, causing “floating mutant proteins” to be secreted by cells into the body instead.
