Oxford University Pauses AstraZeneca Vaccine Trial in Children Amid Blood Clot Concerns

Strategic Insights

— 1 min read

Oxford University has paused a trial of the AstraZeneca COVID-19 vaccine in children as young as 6 years old due to concerns over rare cases of blood clots in adults receiving the vaccine. The trial, which was underway in the UK, has been put on hold while the country's medical regulator reviews the issue. The decision comes as Britain's Medicines and Healthcare products Regulatory Agency (MHRA) has reported seven deaths among 18.1 million administered doses of the vaccine due to rare blood clots.

Key Takeaways:

  • The Oxford University trial of the AstraZeneca COVID-19 vaccine in children has been paused due to concerns over rare cases of blood clots in adults.
  • The trial, which involved children as young as 6 years old, has been put on hold while the UK's Medicines and Healthcare products Regulatory Agency (MHRA) reviews the issue.
  • The MHRA has reported 7 deaths among 18.1 million administered doses of the vaccine due to rare blood clots, including 22 reports of brain blood clots (cerebral venous sinus thrombosis) and 8 reports of clotting in those with low platelets.
  • Despite these concerns, the MHRA has advised the UK to continue administering the vaccine in all groups, citing that blood clotting is rare enough that the benefits outweigh the risks.
  • Other countries, including Germany, have restricted the use of the AstraZeneca vaccine in certain populations, with Germany's independent vaccine commission recommending that those under 60 who have received the first dose complete their inoculation with a different product.
  • June Raine, chief executive of the MHRA, stated that participant safety is the agency's top priority, but no safety concerns have been reported with the Oxford University trial.

Statistics:

  • 18.1 million doses of the AstraZeneca vaccine had been administered in the UK.
  • 7 deaths were reported due to rare blood clots.
  • 22 reports of brain blood clots (cerebral venous sinus thrombosis) were documented.
  • 8 reports of clotting in those with low platelets were reported.
