(CNN)European drug regulators have confirmed a link between the Oxford-AstraZeneca Covid-19 shot and rare blood clots, as UK authorities recommended that people under 30 should take alternative vaccines.
The European Medicines Agency (EMA) said Wednesday that a particular combination of unusual blood clots with low blood platelet counts should be listed as a side effect of the vaccine, but stopped short of recommending its use be limited. The benefits of the shot outweigh the risks and Covid-19 is a "very serious disease," it added.
UK regulators took a more cautious approach, saying healthy adults under 30 should be offered other vaccines. Officials described the move as a "course correction" that would not derail the country's rapid inoculation program.
We're still talking about extremely low rates
Elsewhere, UK regulators said a thorough review of rare and specific types of blood clots continues, and as of Mar 24, officials have received 22 reports of cerebral venous sinus thrombosis (CVST) and 8 reports of thrombosis events with low platelets. The events were among 18.1 million doses of AstraZeneca vaccine that had been given by that date.
A panel from the British Society of Hematology today released interim guidance on diagnosing and managing the rare conditions, which they say have not been definitively linked to vaccination. However, they say the cases are unusual, because despite thrombocytopenia, patients experience progressive thrombosis, mainly venous, with a high preponderance of CVST.
The whole thing seems counterintuitive. The patients are experience thrombosis in spite of having low platelet levels, even though ther reverse should be expected
