Vaccine safety experts from the World Health Organization (WHO) are meeting on Tuesday to review the Oxford-AstraZeneca jab, after several European countries halted their roll-outs.
There have been a number of cases in Europe of blood clots developing after the vaccine was administered.
However, experts say the number of incidents matches the rate typically reported within the general population.
The European Medicines Agency (EMA) is also meeting on Tuesday.
It is expected to issue its decision on the continued use of the Oxford-AstraZeneca vaccination on Thursday.
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.
