German scientists found the cause of blood clots after COVID-19 vaccines: adenovirus, pandemic, coronavirus, sars-cov-2, covid-19, covid-19 vaccine, adenovirus vectors, blood clots

Rare but serious blood clots after vaccination against COVID-19 are caused by adenovirus vectors that penetrate the cell nuclei and can be misread, causing rare diseases, according to a group of German scientists.



'The explanation provided by German researchers is still a hypothesis, as yet unexplored by other experts,' stresses the British daily The Guardian, adding that some scientists have different theories about the link between vaccines and blood clots. According to researchers from the Goethe University in Frankfurt, the problem only concerns vector vaccines in which adenoviruses are the carriers of the immune-inducing spike protein (S proteins). Of the preparations approved in the European Union, AstraZeneca and Johnson & Johnson vaccines are based on this mechanism.
`` Some adenoviruses make their way into the cell nuclei, where some instructions for making coronavirus proteins can be misread, '' the researchers said in an article published Wednesday on Research Square, which collects unreviewed research papers. They add that the resulting proteins can potentially cause blood clotting disorders in a small number of people. - All vaccines based on mRNA [in the EU they are preparations of the companies Pfizer / BioNTech and Moderna - ed. PAP] should be safe products, the researchers write in an article that has not yet been reviewed by other scientists. The authors add that they know how to modify vector vaccines to increase their safety.
