Germans 'solve' Covid vaccine blood clot puzzle: Scientists say rare side effect from AstraZeneca jabs is caused by cold virus used to deliver the jab into the body - and can be fixed

Germans scientists say they have figured out why the Covid vaccines from. AstraZeneca and Johnson & Johnson are linked to rare blood clots. In a new pre-print, the team says the problem is with the adenovirus vector, a common cold virus used to get the body to induce an immune response. They claim the vaccine is sent into the cell nucleus instead of surrounding fluid, where parts of it break off and create mutated versions of themselves. The mutated versions then enter the body and trigger the rare blood clots. Scientists say they can genetically adapt the vaccine to prevent the virus's spike proteins, which it uses to enter cells, from splitting apart
