A preprint, an unpublished non-peer reviewed study, from researchers in Germany presents a theory for why vector-based COVID-19 vaccines, such as Oxford-AstraZeneca and Johnson & Johnson, may cause rare blood clots.

It’s a really interesting hypothesis, that errant processing of the delivered spike gene results in the production of a truncated spike protein, which gets secreted from the cell, potentially triggering blood clotting events.
The data certainly highlights that production of this truncated spike may well occur, but it stops short of providing a concrete link with promotion of blood clotting. Nevertheless, it is certainly something worth investigating further.
