The Oxford-AstraZeneca coronavirus vaccine trial on children and teenagers has been paused while the UK regulator investigates whether there's a possible link with rare blood clots in adults, APA reports citing BBC.
Prof Andrew Pollard from Oxford University has told the BBC while there are no safety concerns with the trial itself, the paediatric clinical trial will not give any further vaccinations while they await for additional information from the MHRA.
Participants in the trial are advised to continue to attend all scheduled visits and can contact the trial sites if they have any questions.
About 300 volunteers signed up for the trial which started in February.
Researchers are assessing whether the jab produces a strong immune response in children aged between six and 17. Updates from the European Medicines Agency and the MHRA are expected in the coming days.
