The World Health Organisation has said there is no evidence that incidents involving blood clots are caused by the Oxford-AstraZeneca vaccine.
In a statement, the WHO said it was reviewing reports relating to the jab, but it was important that vaccination campaigns continued.
It was good practice to investigate potential adverse events, it added.
Germany on Monday joined several other European countries in halting vaccinations as a precaution.
There have been a number of cases in Europe of blood clots developing after the vaccine was administered.
However, experts say the number of blood clots reported after the vaccine were no more than those typically reported within the general population.
About 17 million people in the EU and the UK have received a dose of the vaccine, with fewer than 40 cases of blood clots reported as of last week, AstraZeneca said.
