Top US health authorities said Friday they have not yet found a "causal" link between Johnson and Johnson's Covid shot and blood clots, as the EU drug regulator probed possible instances among those who have received the vaccine.

"At this time, we have not found a causal relationship with vaccination and we are continuing our investigation and assessment of these cases," said a statement from the US Food and Drug Administration regulator.
