It comes after rollout of the jab was last week paused in the US.
The rollout of the jab in Europe was also delayed last week and the EU had been due to receive 55 million doses of the jab.
The EMA today concluded that unusual blood clots associated with low levels of blood platelets would be listed as a rare side effect.
Side effects are common with all medications and vaccines including the coronavirus jabs.
Most people won’t have any side effects, but people suffering them have mainly reported pain at the site of injection and fatigue.
Over 7 million people in the United States have been given the J&J jab.
Out of seven million, there have been just eight reports from the US of the serious blood clots.
Specific risk factors have not yet been confirmed but all patients were under the age of 60 and all cases were confirmed within three weeks of vaccination.
The majority of those affected were women.
The cases had typically occurred in unusual sites such as the veins in the brain – this is also known as cerebral venous sinus thrombosis (CVST).
They also occurred in the abdomen – also known as splanchnic vein thrombosis and in arteries, with low levels of blood platelets and sometimes bleeding.
