A review by the European Union's medicines regulator has concluded the Oxford-AstraZeneca Covid-19 vaccine is "safe and effective".
The European Medicines Agency (EMA) said it would continue to study possible links between rare blood clots and the vaccine.
Its findings came after 13 EU states paused rollouts of the jab.
The World Health Organization (WHO) on Thursday called on countries to continue using the vaccine.
Much of Europe is struggling to contain a surge in coronavirus cases.
Decisions to suspend use of the vaccine sparked concerns over the pace of the region's vaccination drive, which had already been affected by supply shortages.
