Nicola Sturgeon has attempted to reassure Scots after several countries in Europe halted the AstraZeneca vaccine over blood clotting issues.
The First Minister said the medical body, the Medicines and Healthcare products Regulatory Agency, responsible for vaccines in the UK was monitoring the problem.
Ireland stopped injecting its population with the jab yesterday, while the Netherland temporarily halted the rollout.
A review released by Norway's medical agency over the weekend led to a number of countries suspending the vaccine while they investigate further.
So far the Netherlands, Denmark and Iceland have stopped their programmes.
Sturgeon tried to calm any concerns about the jab at her daily briefing earlier today.
She said: "In the UK, the decision to suspend the use of any vaccine is a matter of the Medicines and Healthcare products Regulatory Agency.
"The MHRA has confirmed to us that there is no current evidence of an increase in blood clots being caused by the AstraZeneca vaccine.
"That is the issue that has paused the vaccine in some other countries.
"As you would expect, though, the MHRA is continuing to monitor this carefully, and remains in regular contact with other regulators."
Meanwhile, Downing Street also attempted to reassure people.
The Prime Minister's official spokesman said: "The Oxford/AstraZeneca vaccine remains both safe and effective, and we urge anybody asked to come forward to receive a vaccine to do so."
There was "no evidence" that blood clots are any more likely to occur following vaccination, the spokesman said.
